I've been using my laptop for about two years, for an average of probably several hours of power-on a day. The design_charge is 2000000, and the current / now charge is 1792000, so I suppose it hasn't degraded too badly yet. This is, I believe, a bottom of the barrel battery, on a rather low end system, which I guess also means less power draw, although my understanding is that the Celeron has crippled power management. When new, I got a fairly consistent 1.5 hours till shutdown, and I haven't done a drain test recently. You mention overcharging; as Ismael says in another message in this thread, the system seems to know when the battery is full and stops charging; the power LED goes from red to green, and ACPI reports "full", not "charging". Does it really keep charging, to the detriment of the batter?
