maximizing Li-ion battery life

I own a ThinkPad Edge 15 with a 9 cell 2.8Ah Li-Ion Battery. Hoping someone has an informed opinion about when to use battery vs AC adapter. I'm guessing that even if I ALWAYS have access to AC power, I should occasionally operate my laptop off the battery-alone to discharge battery. However, I have no idea what's the happy medium. Thanks in advance for any input.

Re: maximizing Li-ion battery life

I can understand very well your question on battery.

 

I suggest you after the battery charge up to 100 percent then you should remove the power adapter and once the battery left with 5 to 10 percent then connect the power adapter.

 

You need to make sure if the power adapter is connected to the laptop then it should disconnect after the battery charge up to  100 percent.

 

To know more detail on the batter please refer to the mentioned below web link.

Re: maximizing Li-ion battery life

Not sure whether the Thinkvantage power manager has the battery maintenance function. But for general uses you use the battery reset option every 2 to 3 months when you are not always discharging the battery from full to 5% and then recharging back again.
