How long should a laptop battery last?
How long a laptop battery should last after each charge?
After the laptop has gone through a full single charge and the power adapter is unplugged, the average life of a laptop battery can be anywhere between one and six hours. This time is dependent on the battery, its capacity (mAH), what's being done on the laptop, and how old the battery is. Over time, the laptop battery's capacity decreases, which means the battery will not last as long as it did when you first got the laptop and will continue to decrease over time.

What's the overall life of a laptop battery?
A laptop computer battery should last between two and four years, or around 1,000 full charges. The total lifetime of a battery is dependent on the type of battery your laptop has (NiCad, NiMH, or Li-ion), how much you use the battery, how it's charge, and how well you take care of the battery.
