A laptop battery is a consumable component. Even when a laptop is otherwise working perfectly, its battery gradually loses capacity because lithium-ion and lithium-polymer cells chemically age with time and charge cycles. When rep...
A modern laptop battery is much more than a collection of lithium-ion cells connected to a charging circuit. Inside most laptop battery packs is a Battery Management System (BMS) containing a controller, protection circuitry, temp...
A laptop showing 100% battery charge should normally be able to operate for some time after the charger is disconnected. However, an aging or faulty laptop may display 100%, 80%, or even 50% battery and then switch off instantly o...

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...
Laptop battery swelling is a serious hardware and safety issue that should never be ignored. A swollen battery can push against the laptop's bottom cover, keyboard, touchpad, display assembly, or internal components. In severe cas...
...8-cell, or 9-cell batteries. When buying a laptop or replacing an old battery, users often assume that a battery with more cells will automatically provide longer backup. That can be true, but cell count alone does not determin...
Laptop battery calibration is frequently recommended when a laptop suddenly shuts down despite showing remaining charge, the battery percentage behaves erratically, or Windows reports an inaccurate remaining runtime. However, batt...
A laptop battery does not retain its original capacity forever. Lithium-ion and lithium-polymer batteries gradually lose their ability to store energy because of charge cycles, temperature, age, charging habits, workload, and norm...
A laptop that once provided several hours of battery backup may gradually begin losing charge much faster. In some cases, the battery percentage drops rapidly even when the laptop is idle. In others, the laptop becomes warm, the f...
Laptop battery technology has improved significantly over the years, but most modern portable computers still rely on two closely related rechargeable battery technologies: Lithium-ion (Li-ion) and Lithium-Polymer (Li-Po or Li-Pol...
When replacing an old laptop battery, you may find that the original battery is marked 11.1V, while a replacement advertised for the same laptop model is marked 10.8V. This naturally raises an important question: Can an 11.1V lapt...
When checking a laptop battery, you will commonly find specifications such as: 11.4 V 15.2 V 3,500 mAh 5,000 mAh 42 Wh 56 Wh 86 Wh These numbers describe different electrical characteristics of the battery. A common mistake is to ...
