Battery Life

[dc81]

Just a quick questions here. About 2 months ago I purchased a T41p refurb (in excellent condition) but the battery had 15 cycles on it. How many cycles can an average 9 cell battery have?

Depends on how many are put on it.

Actually, mine has 89 Cycles on it right now; it will be 90 Cycles by tonight. A Cycle refers to a discharge and recharge according to the thresholds set in the Power Manager. That doesn't always reflect the wear level of the battery though. A good thing to do is to get NHC and check the wear level of the battery. Just a note, don't try to fully discharge LiIon Batteries completely; that will increase the wear level quite significantly. I usually go down to around 5% if I need to use up all of the battery.
