[MOVED] Is it necessary to replace my laptop battery?

[laptopxwjj]

I've bought my laptop about 1 year ago. At first, my laptop battery can back me about one and half hours. Every time when i start my laptop, it always says the battery is low and it can only last for less than 30 minutes. One of mu friends has told me to do something to prolong the life of my laptop battery. Is it complicated Or Is it necessary for me to buy a new one?

If you have charged and discharged the battery every day then that makes hundreds of cycles. That is a lot for rechargeable batteries. So it is not surprising if their capacity is declining.

Eventually you will need a new battery pack.

Do you see a light which indicates that the batteries are charging? It should go off after a while. As long as the batteries get charged, things are still working okay.

Windows OS has a battery monitor control panel. You can observe its remaining capacity, and you can see how quickly it is charging or discharging.
