Actually, it's the 100% charge state that is bad for LiIon. But a charge/drain cycle will likely wear the battery out even faster - LiIon batteries wear model is based on usage time. A 90% charge is ideal for long term storage - or for someone who leaves the laptop plugged into AC power most of the time.
As far as software controls, I'm not familiar - but one thing that works in any OS is to simply remove the battery when on AC power.

Hello all: Does anyone know of a tool/project that will allow me to read the battery condition (not the charge status) on a Dell laptop battery? Under XP there is a utility that warns that the battery is still holding a charge but that the battery is degraded and should be replaced.
Also, not sure if this is possible, but I would like to control how the laptop charges the battery. I tend to have the laptop plugged in most of the time and this constant charging state is apparently very bad for battery lifetime. So a charge/drain cycle is supposedly better.
Thanks, Kwan _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
