When it comes to laptop batteries, it's normal for them to lose their ability to maintain maximum capacity as they age. Generally, after 1 to 2 years or 300 to 400 charge cycles, laptop batteries become problematic and need to be replaced. If your laptop is old, it's likely that the battery has already died and needs to be changed. You'll know it's time to replace the battery if your laptop can charge it but it doesn't last long enough or has 25% or less of its maximum capacity.
As you use it and it weakens, you'll notice that your laptop doesn't seem to last as long on the battery. If your laptop doesn't have a battery that can be repaired by the user, you'll need to contact the manufacturer so they can open it and replace the battery. If your device is still operating normally, you don't have to change the battery yet. However, if you never use the battery, such as if you use your laptop on your desktop most of the time and it's quite hot, which is bad for the battery, removing it can certainly help extend its life.
If the battery starts to fail within the warranty period, the easiest thing is to contact the manufacturer, as they may cover the part and the replacement. If your laptop has a user-repairable battery, that is, one that you can remove on your own, you can order a replacement battery for your laptop model online. If the warranty has expired, you can take the device to a repair shop or replace the battery yourself. Windows warned us that the time had come to replace the battery and the battery seemed to have a wear level of 27.7% depending on its reported capacity.
You may expose it to too much heat if you leave the battery on while playing demanding and exhausting PC games on your laptop.In conclusion, if you want your laptop to last longer and perform better, you should plan to replace its battery at some point.
