Question about note book batteries. By keeping the ac power plugged in all the time, will that do damage to the battery or shorten the life of the battery?
Some one in Bestbuy told me that it will shorten the life of the battery, if kept plugged in all the time with battery installed.

Thanks

It shouldn’t matter if you have a recent Lithium-Ion battery pack.

It’s all in the temperature regarding Li-Ion. From Wikipedia:

At a 100% charge level, a typical Li-ion laptop battery that is full most of the time at 25 °C or 77 °F will irreversibly lose approximately 20% capacity per year.
Standard performance on old Li-Ions, should be way better these days.

However, a battery in a poorly ventilated laptop may be subject to a prolonged exposure to much higher temperatures, which will significantly shorten its life. Different storage temperatures produce different loss results: 6% loss at 0 °C (32 °F), 20% at 25 °C (77 °F), and 35% at 40 °C (104 °F). When stored at 40%–60% charge level, the capacity loss is reduced to 2%, 4%, 15% at 0, 25 and 40 degrees Celsius respectively

Lithium-ion polymer batteries are somewhat in the same results.

O.K. Thanks again.
