How long should a laptop battery last?
The life of a laptop battery operating under normal conditions should be between 500 to 800 charge-discharge cycles. This translates into one and a half to three years of laptop battery life for the average user. As your laptop battery begins to die, you will notice a decline in the running time of the laptop battery. When your two hour battery is only supplying you with twenty minutes worth of use, it is time for a new one. When a laptop battery is not used for extensive periods of time it should be removed from the device and stored in a cool, dry and clean environment. Self-discharge will occur when the battery is not used for an extended time period. Fully charge the battery before use after storage. Long term storage will have permanent effects on the laptop battery's capacity.
