When replacing an aging laptop battery, you may find replacement batteries advertised with a higher mAh (milliampere-hour) rating than the original battery. For example, your laptop may originally have a 4,000 mAh battery, while a compatible replacement is advertised as 5,000 mAh or 6,000 mAh.

This naturally raises several questions:

Can a laptop safely use a higher-mAh battery? Will it damage the laptop? Will the charger handle it? Does higher mAh actually mean longer battery life?

In many cases, yes, a higher-mAh battery can be used safely, provided the replacement battery is genuinely compatible with the laptop. Capacity alone does not determine compatibility. Voltage, battery chemistry, cell configuration, physical dimensions, connector pinout, battery management electronics, firmware communication, and manufacturer specifications can all matter.

A higher mAh rating normally means the battery can store more charge and potentially operate the laptop for longer between charges. It does not mean that the battery will force additional current into the laptop.

This guide explains the technical details.

1. What Does mAh Mean in a Laptop Battery?

mAh stands for milliampere-hour.

It represents electrical charge capacity.

For example:

• 4,000 mAh = 4 Ah
• 5,000 mAh = 5 Ah
• 6,000 mAh = 6 Ah

In simplified terms, a higher mAh rating means the battery can theoretically supply a given current for a longer period.

If two batteries operate at the same voltage, the battery with the higher mAh capacity generally stores more energy.

For example:

Battery A: 11.4 V, 4,000 mAh
Battery B: 11.4 V, 5,000 mAh

Battery B has approximately 25% more charge capacity.

However, mAh should not be considered independently of voltage.

2. mAh vs Wh: Which Is More Important?

For comparing laptop battery capacity, Wh (watt-hours) is usually more useful than mAh.

The relationship is:

Wh = Voltage × Ah

Because:

Ah = mAh ÷ 1000

the formula can also be written as:

Wh = Voltage × mAh ÷ 1000

For example, consider a battery rated:

11.4 V, 4,000 mAh

Its approximate energy capacity is:

11.4 × 4,000 ÷ 1000 = 45.6 Wh

Now consider:

11.4 V, 5,000 mAh

Its capacity is:

11.4 × 5,000 ÷ 1000 = 57 Wh

The second battery therefore stores approximately:

57 Wh ÷ 45.6 Wh = 1.25

or about 25% more energy.

This is why Wh is generally the better figure when estimating potential laptop runtime.

3. Can You Install a Higher mAh Battery?

Yes, in many cases.

Suppose the original battery is:

11.4 V, 4,000 mAh, 45.6 Wh

and a replacement battery is:

11.4 V, 5,000 mAh, 57 Wh

If the replacement is specifically compatible with the laptop and has the correct:

• voltage
• battery chemistry
• connector
• pinout
• physical design
• battery management system
• communication protocol
• cell configuration
• part-number compatibility

then the higher 5,000 mAh capacity is normally not a problem.

The laptop consumes the current it requires. The battery does not simply push its full capacity into the motherboard.

4. Higher mAh Does Not Mean Higher Current Is Forced Into the Laptop

This is one of the most common misunderstandings.

A battery rated at 6,000 mAh does not continuously send 6,000 mA into the laptop.

The mAh figure describes capacity, not the amount of current that must flow at any particular moment.

For example, if the laptop requires approximately 2 A under a particular workload, a compatible battery capable of supplying that load provides approximately what the system requires.

Conceptually:

4 Ah battery at 2 A load → about 2 hours

6 Ah battery at 2 A load → about 3 hours

Real laptop runtime will differ because of conversion losses, varying system power consumption, battery reserve limits, temperature, battery aging, and power-management behavior.

The important concept remains:

Higher capacity generally increases potential runtime rather than forcing higher power into the laptop.

5. Voltage Is Critical

When choosing a replacement laptop battery, voltage compatibility is much more important than simply finding a higher mAh number.

For example:

Original battery:

11.4 V, 4,000 mAh

Replacement:

11.4 V, 5,000 mAh

This may be suitable if all other specifications match.

But suppose the replacement is:

14.8 V, 5,000 mAh

You should not assume it is compatible merely because it physically fits or has a higher capacity.

Laptop battery voltage is related to cell chemistry and series configuration.

For example, lithium-ion battery packs may be based on configurations such as:

• 2-cell series
• 3-cell series
• 4-cell series

Different lithium chemistries and manufacturer labeling conventions can also result in ratings such as 7.4 V, 7.6 V, 7.7 V, 10.8 V, 11.1 V, 11.4 V, 11.55 V, 14.4 V, 14.8 V, 15.2 V, and others.

Do not decide compatibility from a voltage number alone.

Use the laptop manufacturer's supported battery specifications and replacement part numbers.

6. Why Some Replacement Battery Voltages Look Slightly Different

Users sometimes find an original battery marked:

10.8 V

while a replacement is marked:

11.1 V

or an original marked:

14.4 V

while another battery is:

14.8 V

Some such batteries may be compatible because lithium-cell nominal voltages and labeling conventions differ.

However, this should never be assumed.

The correct approach is to verify:

Does the battery manufacturer explicitly list the replacement as compatible with the exact laptop model or original battery part number?

If yes, the voltage difference may be intentional and supported.

If not, avoid experimenting based solely on physical fit.

7. Battery Part Number Is Extremely Important

Laptop manufacturers commonly assign batteries specific part numbers.

Examples may include manufacturer-specific identifiers for:

• battery assemblies
• spare parts
• replacement packs
• regional variants
• different capacities for the same laptop family

When buying a higher-capacity replacement, compare the original battery part number with the replacement manufacturer's compatibility list.

This is often safer than searching only for:

"Battery for Laptop XYZ"

because one laptop series can have multiple generations and battery designs.

8. Physical Size Must Match

A higher-capacity battery may require more or larger cells.

For removable batteries, manufacturers historically offered:

• standard batteries
• extended batteries
• high-capacity batteries

An extended battery could protrude from the rear or bottom of the laptop.

Modern laptops generally use internal batteries, so the replacement must fit within a precisely defined internal space.

Check:

• length
• width
• thickness
• mounting holes
• screw positions
• cable length
• connector orientation
• battery shape
• clearance around components

Never force a battery into the chassis.

9. Connector and Pinout Must Match

Two batteries can have similar voltage and capacity but completely different electrical interfaces.

Modern laptop batteries may contain connections for:

• positive power
• negative/ground
• SMBus communication
• temperature sensing
• identification
• battery presence
• protection signals
• manufacturer-specific communication

A connector that appears physically similar does not guarantee identical wiring.

An incorrect pinout could cause malfunction or hardware damage.

Therefore, connector and part-number compatibility should be verified before installation.

10. Battery Management System Compatibility

A modern laptop battery is not merely a group of lithium cells.

It normally contains a Battery Management System (BMS) and protection electronics.

Depending on design, these electronics can monitor:

• pack voltage
• individual cell conditions
• current
• temperature
• charging state
• discharge state
• remaining capacity
• cycle count
• overcurrent conditions
• overvoltage conditions
• undervoltage conditions
• thermal conditions

The battery may also communicate information to the laptop's embedded controller.

A poor-quality replacement may have acceptable-looking specifications but unreliable electronics.

Possible symptoms include:

• battery not detected
• incorrect charge percentage
• sudden shutdown
• battery stuck at a particular percentage
• battery not charging
• inaccurate remaining-time estimates
• firmware warnings

This is one reason battery quality matters as much as advertised mAh.

11. Will a Higher mAh Battery Damage the Laptop?

A properly designed, compatible higher-capacity battery should not damage the laptop merely because it has a higher mAh rating.

Consider:

Original:

11.4 V, 4,000 mAh

Replacement:

11.4 V, 5,500 mAh

The replacement has approximately 37.5% greater charge capacity.

It does not mean that 37.5% more current is automatically sent through the motherboard.

The laptop's load and power-management circuitry determine current draw according to operating conditions.

Problems arise when the battery is:

• electrically incompatible
• incorrectly wired
• physically unsuitable
• based on inappropriate cells
• equipped with poor protection electronics
• counterfeit
• defective
• unsupported by the laptop

The danger is incompatibility or poor construction, not higher mAh by itself.

12. Will a Higher mAh Battery Take Longer to Charge?

Potentially, yes.

A larger battery stores more energy, so if the charging system operates at approximately the same effective charging power, a higher-capacity battery may take longer to charge.

For example, suppose two compatible batteries have:

Battery A: 45 Wh

Battery B: 60 Wh

Battery B stores approximately 33% more energy.

It may therefore require more time to charge from the same starting percentage under similar conditions.

However, actual charging time depends on:

• charger wattage
• laptop charging circuitry
• battery charge profile
• battery temperature
• laptop workload
• USB-C Power Delivery negotiation, where applicable
• charging limits
• fast-charging support
• battery age

Charging is also not performed at constant maximum power from 0% to 100%, so simple division gives only a rough estimate.

13. Do You Need a Bigger Charger?

Usually not merely because the battery capacity is higher.

If the replacement battery is officially compatible with the laptop, the existing correct charger is generally intended to work with the laptop's charging system.

A higher-capacity battery may simply take longer to reach full charge.

For example, replacing a 50 Wh battery with a compatible 70 Wh battery does not automatically mean that a 65 W laptop charger must be replaced with a higher-wattage charger.

The laptop's charging electronics determine how much charging power is accepted.

Use a charger meeting the laptop manufacturer's required voltage, wattage, connector, and protocol specifications.

14. Does Higher mAh Increase Laptop Performance?

Generally, no.

A higher-capacity battery primarily affects how much energy can be stored.

It does not directly increase:

• CPU speed
• RAM
• SSD performance
• GPU performance
• display refresh rate
• application speed

Its main benefit is potentially longer battery runtime.

There are special cases where laptop performance policies differ depending on battery state, charger connection, temperature, or power limits, but this is not a direct consequence of a larger mAh rating.

15. How Much More Runtime Can You Expect?

If voltage remains the same, capacity increases can provide a rough indication.

Suppose:

Original battery = 4,000 mAh

Replacement = 5,000 mAh

Increase:

(5,000 − 4,000) ÷ 4,000 × 100 = 25%

The replacement has 25% greater rated charge capacity.

If the original battery when new delivered 4 hours under a particular workload, an idealized estimate might be:

4 × 1.25 = 5 hours

But this is only an approximation.

Actual runtime depends heavily on:

• screen brightness
• CPU utilization
• GPU utilization
• Wi-Fi activity
• Bluetooth
• external USB devices
• SSD/HDD activity
• background applications
• browser tabs
• video playback
• gaming
• Windows power mode
• cooling fans
• battery temperature
• battery health

For batteries of different voltages, compare Wh rather than mAh.

16. Example: Why mAh Alone Can Be Misleading

Consider two hypothetical batteries.

Battery A

7.6 V, 6,000 mAh

Energy:

7.6 × 6 = 45.6 Wh

Battery B

11.4 V, 4,500 mAh

Energy:

11.4 × 4.5 = 51.3 Wh

Battery A has the larger mAh number:

6,000 mAh vs 4,500 mAh

but Battery B stores more rated energy:

51.3 Wh vs 45.6 Wh

Therefore:

Do not compare laptop batteries by mAh alone.

Compare Wh when evaluating energy capacity, and separately verify electrical and mechanical compatibility.

17. Can You Replace a 4,000 mAh Battery With a 6,000 mAh Battery?

Potentially yes.

Suppose the original is:

11.4 V
4,000 mAh
45.6 Wh

and the replacement is:

11.4 V
6,000 mAh
68.4 Wh

The replacement stores approximately 50% more energy.

If the battery is fully compatible with the laptop, it could theoretically provide approximately 50% more runtime under comparable conditions.

But before installation, confirm:

• supported laptop model
• original battery part number
• nominal voltage
• connector
• pinout
• dimensions
• mounting points
• battery chemistry
• BMS compatibility
• firmware compatibility

18. Can You Use a Lower mAh Battery?

Potentially yes, if it is otherwise an approved compatible battery.

For example:

Original:

11.4 V, 5,000 mAh

Replacement:

11.4 V, 4,000 mAh

If the replacement is supported, the laptop may function normally but have shorter runtime.

Lower capacity itself does not necessarily create a compatibility problem.

Again, compatibility should be verified using manufacturer specifications rather than mAh alone.

19. Battery Chemistry Matters

Laptop batteries commonly use lithium-based rechargeable cells, but exact chemistry and design can vary.

You should not replace one battery design with another simply because:

• voltage looks close
• capacity looks higher
• connector appears to fit

The laptop's charging system and battery electronics are designed around expected battery characteristics.

Always use a replacement specifically designed for the laptop.

20. OEM vs Third-Party Higher-Capacity Batteries

There are generally two replacement categories.

OEM Battery

An OEM battery comes from or is supplied for the original laptop manufacturer.

Advantages may include:

• known compatibility
• proper communication
• expected physical fit
• manufacturer support
• appropriate safety design

The disadvantage can be higher cost or limited availability for older laptops.

Third-Party Battery

Third-party batteries can be useful, particularly for older laptop models where original batteries are unavailable.

However, quality varies considerably.

A reputable third-party replacement should provide clear information about:

• supported laptop models
• compatible battery part numbers
• voltage
• capacity
• Wh
• warranty
• safety/protection features
• manufacturer or supplier identity

Avoid buying based solely on the largest mAh number.

21. Be Careful With Unrealistic Capacity Claims

Some low-quality replacement batteries advertise extremely high mAh values.

For example, if an original internal battery of a particular physical size is rated around 4,000 mAh and an unknown replacement of essentially identical size claims 10,000 mAh, the claim deserves scrutiny.

Battery energy density has physical limitations.

A dramatically higher capacity in the same space may indicate:

• misleading labeling
• low-quality cells
• manipulated specifications
• incorrect capacity calculations
• counterfeit products

A realistic, reputable 5,000 mAh battery may provide better service than an unknown battery claiming 10,000 mAh.

22. Check Wh Along With mAh

Suppose a replacement is advertised as:

11.4 V
5,000 mAh
57 Wh

Check the mathematics:

11.4 × 5 = 57 Wh

The figures are internally consistent.

If the listed voltage, mAh, and Wh values do not approximately agree, investigate before purchasing.

Remember that manufacturers may round ratings, so small differences are normal.

23. How to Identify Your Existing Battery Specifications

Depending on the laptop, specifications can be obtained from:

• battery label
• laptop service manual
• manufacturer support website
• BIOS/UEFI
• diagnostic software
• Windows battery report

In Windows, open Command Prompt or PowerShell and run:

powercfg /batteryreport

Windows generates an HTML battery report.

It may contain information such as:

• battery name
• manufacturer
• serial number
• chemistry
• design capacity
• full charge capacity
• cycle count, when available
• recent battery usage
• capacity history

Note that Windows commonly reports capacity in mWh, not mAh.

24. Design Capacity vs Full Charge Capacity

These two values are important when determining whether a battery actually needs replacement.

Design Capacity

The energy capacity the battery was designed to provide when new.

Full Charge Capacity

The amount of energy the battery currently estimates it can hold at full charge.

For example:

Design Capacity: 60,000 mWh

Full Charge Capacity: 42,000 mWh

Approximate battery health:

42,000 ÷ 60,000 × 100 = 70%

So the battery is operating at approximately 70% of its original design capacity according to the reported values.

25. Higher Rated Capacity vs Battery Health

Do not confuse battery capacity specification with battery health.

Suppose:

Original battery design capacity:

50 Wh

Old battery current full charge capacity:

30 Wh

New replacement:

65 Wh

Compared with the worn 30 Wh battery, the new 65 Wh replacement could appear to provide more than twice the usable energy.

But compared with the original battery's 50 Wh design capacity, the increase is:

(65 − 50) ÷ 50 × 100 = 30%

So distinguish between:

• original design capacity
• current degraded capacity
• replacement rated capacity

26. Does Windows Need Configuration After Installing a Higher-Capacity Battery?

Normally, no special Windows configuration is required.

The laptop's battery controller and operating system obtain battery information from the battery and embedded controller.

After replacement, Windows should automatically recognize the battery if it is compatible.

However, initially you may see inaccurate:

• percentage estimates
• remaining runtime
• charge predictions

The battery gauge may improve after normal charge/discharge usage and controller learning.

Follow the battery or laptop manufacturer's calibration procedure if one is provided.

Avoid repeatedly deep-discharging lithium-ion batteries merely for routine calibration.

27. What If the Laptop Says "Battery Not Detected"?

If a replacement battery is installed and Windows or BIOS reports:

Battery not detected

possible causes include:

• incompatible battery
• connector not fully seated
• defective battery
• BMS communication problem
• damaged connector
• firmware compatibility issue
• battery protection state
• motherboard charging problem

If the original battery is detected but the replacement is not, the replacement battery or its compatibility becomes a primary suspect.

28. What If the Battery Is Detected but Does Not Charge?

Possible causes include:

• incompatible battery
• defective BMS
• unsuitable charger
• charger wattage problem
• damaged charging port
• USB-C PD negotiation issue
• battery temperature protection
• BIOS/firmware issue
• charging threshold configured by manufacturer software
• hardware failure

Do not automatically assume that the higher mAh rating is responsible.

29. Battery Safety Is More Important Than Capacity

Lithium batteries contain significant stored energy.

Poor-quality or damaged batteries can create risks including:

• overheating
• swelling
• leakage
• smoke
• fire
• damage to the laptop chassis
• trackpad deformation
• internal component pressure

Stop using a battery if it is visibly swollen, physically damaged, unusually hot, leaking, or producing unusual odor or smoke.

A swollen internal battery should not be compressed or punctured.

30. Signs of a Poor Replacement Battery

Be cautious if a new replacement battery shows symptoms such as:

• capacity drops rapidly
• laptop shuts down at 20–40%
• battery percentage jumps unexpectedly
• battery becomes excessively hot
• battery does not charge fully
• BIOS repeatedly reports battery errors
• battery swells
• runtime is far below advertised capacity
• charge level remains stuck
• system reports inconsistent capacity

These symptoms can indicate defective cells, poor BMS calibration, inaccurate specifications, or incompatibility.

31. Higher mAh vs Higher Wh: Final Rule

If voltage is identical:

Higher mAh = higher Wh

For example:

11.4 V × 4 Ah = 45.6 Wh

11.4 V × 6 Ah = 68.4 Wh

But if voltage differs, comparing mAh alone is misleading.

Therefore, when comparing battery energy capacity:

Use Wh.

When checking battery compatibility:

Use the manufacturer's supported battery specifications and part numbers.

32. Replacement Battery Compatibility Checklist

Before purchasing a higher-mAh laptop battery, verify:

1. Exact laptop model
2. Original battery part number
3. Replacement battery compatibility list
4. Nominal voltage
5. Battery chemistry/design
6. Wh capacity
7. mAh capacity
8. Connector type
9. Connector pinout
10. Physical dimensions
11. Mounting positions
12. Cable position and length
13. BMS compatibility
14. BIOS/firmware compatibility
15. Charger requirements
16. Supplier reputation
17. Warranty
18. Safety certification information where applicable

If all critical compatibility requirements are satisfied, a higher capacity can be a useful upgrade.

33. Practical Example

Suppose a laptop originally uses:

Voltage: 11.4 V
Capacity: 4,200 mAh
Energy: approximately 47.9 Wh

You find a replacement:

Voltage: 11.4 V
Capacity: 5,200 mAh
Energy: approximately 59.3 Wh

Capacity increase:

(5,200 − 4,200) ÷ 4,200 × 100 ≈ 23.8%

Under comparable operating conditions, the new battery could theoretically provide around 24% greater runtime than the original battery when it was new.

If the existing battery has already degraded significantly, the observed improvement may be much larger.

But this is appropriate only if the replacement is designed for the laptop.

34. Does Higher Capacity Make the Laptop Heavier?

Possibly.

If additional capacity is achieved through:

• more cells
• larger cells
• larger enclosure

then the battery can be heavier.

For older laptops with removable extended batteries, the difference can be noticeable.

For internal laptop batteries, the chassis normally limits physical size, so compatible higher-capacity versions must still fit within the available battery compartment.

35. Is the Highest mAh Battery Always Best?

No.

Consider three hypothetical choices:

Battery A: OEM, 4,500 mAh
Battery B: reputable compatible replacement, 5,200 mAh
Battery C: unknown seller, 9,000 mAh

Battery C may appear best from the advertised capacity, but capacity is meaningless if:

• specifications are false
• cells are poor quality
• BMS is unreliable
• battery life is short
• safety is questionable
• laptop compatibility is poor

A battery should be selected on compatibility, quality, safety, warranty, and realistic capacity, not the largest printed number.

36. Recommended Approach

If you want longer laptop runtime, a higher-capacity replacement can be an effective option when the laptop supports it.

Prioritize replacement criteria in roughly this order:

Compatibility → Voltage/design → Part number → Connector/pinout → Physical fit → BMS/firmware support → Quality/safety → Capacity

Do not reverse the process by buying the battery with the highest mAh and then trying to determine whether it can be made to work.

Conclusion

Yes, you can often use a higher-mAh battery in a laptop, provided the battery is specifically compatible with the laptop.

Higher mAh means greater charge capacity. At the same voltage, it also means greater energy capacity and therefore potentially longer runtime.

A higher-capacity battery does not automatically push excessive current into the laptop.

However, mAh is only one specification. A safe replacement should also match or be explicitly compatible in terms of:

• voltage
• battery design and chemistry
• physical dimensions
• connector
• pinout
• battery management system
• firmware communication
• laptop model
• original battery part number

For comparing how much energy batteries store, Wh is generally more informative than mAh.

The safest rule is simple:

Choose the highest-quality battery that is explicitly designed for your exact laptop and supported battery part number. Treat additional mAh or Wh as a capacity benefit only after compatibility has been established.

Frequently Asked Questions (FAQ)

1. Can I replace a 4,000 mAh laptop battery with a 5,000 mAh battery?

Yes, if the 5,000 mAh battery is explicitly compatible with your laptop, including voltage, connector, pinout, physical fit, battery electronics, and supported part number.

2. Will higher mAh damage my laptop?

Not by itself. A higher mAh rating represents greater capacity. An incompatible voltage, pinout, BMS, or poorly constructed battery is the greater concern.

3. Does higher mAh mean higher voltage?

No. mAh measures charge capacity, while volts measure electrical potential. They are different specifications.

4. Does higher mAh mean longer battery life?

Usually it means longer runtime per charge when comparing compatible batteries at the same voltage. Long-term battery lifespan depends on chemistry, cell quality, temperature, charging behavior, and usage.

5. Should I compare mAh or Wh?

Use Wh to compare stored energy, especially when battery voltages differ.

6. Can I use a 6,000 mAh battery instead of 4,000 mAh?

Potentially yes, provided the 6,000 mAh battery is designed and certified by its manufacturer as compatible with your laptop.

7. Will a larger battery charge more slowly?

It may take longer because it stores more energy, assuming the laptop's effective charging power remains similar.

8. Do I need a more powerful charger for a higher-mAh battery?

Usually not simply because capacity increased. Use a charger meeting the laptop manufacturer's specifications.

9. Will higher mAh increase laptop speed?

No. Battery capacity does not directly increase CPU, GPU, RAM, or SSD performance.

10. Can I use a battery with slightly different voltage?

Do not assume compatibility. Some apparently different nominal voltage ratings can be compatible in particular battery families, but this should be verified through manufacturer specifications and part-number compatibility.

11. Is an aftermarket higher-capacity battery safe?

It can be if produced by a reputable manufacturer and specifically designed for the laptop. Quality varies significantly among third-party batteries.

12. Why does a new battery show the wrong percentage?

Battery gauge estimates can initially be inaccurate. Normal usage or a manufacturer-recommended calibration procedure may improve reporting.

13. Why is my new battery not detected?

Possible causes include incompatibility, improper connection, defective BMS, defective battery, firmware issues, or motherboard problems.

14. Is a 60 Wh battery better than a 45 Wh battery?

If both are fully compatible and comparable in quality, the 60 Wh battery stores approximately 33% more rated energy than the 45 Wh battery.

15. Can I install a battery with lower mAh?

Yes, if it is an approved compatible battery, but expected runtime will generally be lower.

16. Is a 10,000 mAh laptop battery always better than 5,000 mAh?

No. Check voltage, Wh, physical size, compatibility, manufacturer reputation, and whether the capacity claim is realistic.

17. How can I check battery capacity in Windows?

Run:

powercfg /batteryreport

Then open the generated HTML report and inspect Design Capacity and Full Charge Capacity.

18. What is the difference between mAh and battery health?

mAh is a capacity specification. Battery health describes how much capacity an aging battery retains relative to its original design capacity.

19. Can a higher-capacity battery overcharge my laptop?

Capacity itself does not cause overcharging. Charging is managed by the battery and laptop charging electronics. An unsafe or defective battery, however, should not be used.

20. What is the most important specification when replacing a laptop battery?

There is no single number that establishes compatibility. Start with the exact laptop model and supported battery part number, then verify voltage/design, connector, physical fit, electronics, and capacity.
