    So I was reading some articles online about prolonging lithium ion battery life. I recently got a new battery because my old one didn't work anymore..the second I'd unplug the power cord, the laptop would shut off because the battery was no longer good. So what can I do best to prolong the battery life?

    I don't use my laptop for many "mobile" purposes and usually just keep it plugged into the AC cord on my desk I'd say 90% of the time. So should I occasionaly run just on battery power to a partial discharge and then fully charge it? I've read that full discharges are not good for LI batters, but should be done about once a month. So I guess my main question is since I don't use my laptop away from an outlet that much, what should I do? Remove the battery completely? Thanks for your input

    Modern laptops have "smart chargers" that properly maintain the battery.

    I never bother with removing or cycling the battery, my present one is 2 years old and still runs fine (on the rare occasion it gets used).

    My opinion is that cycling the battery may add a very small percentage of life, but unless you know exactly what the optimum cycling is for that exact battery construction, you may also subtract a small percentage of life. But we will never know what the optimum for that construction is...

    I work on the theory of leaving it alone and letting tha laptop take care of it. Thats what its designed for.

    If you feel the need, everything you never needed to know on rechargeable batteries is here:
