I checked mine: they are bad
Before I read about this problem I had been thinking something was wrong with my battery. I could never "catch it in the act" but it seemed like one moment I would have lots of charge and then poof it would drop from an hour of reserve time to sleep mode.

I get the battery instant discharge as well. At 100%, the menubar indicator gives me about 1:30. But it usually only makes it about 30 minutes (to around 60%) where it instantly discharges to 1% and goes to sleep. Verified looking at the pretty little lights on the battery.

Same problem here -- Call AppleCare!
A few months back, I had the exact same problem with my iBook G3/600 (16 VRAM) battery. It would drain normally from 100% down to about 50%, at which point the charge would abruptly drop to zero and the machine would go to sleep. A quick call to Apple tech support had me resetting the PRAM, NVRAM, power manager, and other "standard" things, but to no avail. It was quickly determined that my four-month old battery was defective, and I was couriered a replacement the following day under the AppleCare warranty. I believe "decent" battery performance is covered under the AppleCare extended warranty plan. I recharge my battery at least once a day, so I can easily reach the "average" life-expectancy of 500-600 cycles for Li-Ion cells before a year is up. Considering the cost of a new iBook battery, the AppleCare warranty will pay for itself in new batteries alone! FWIW, my replacement iBook battery that's about four months and maybe 200 charge-cycles old shows:
with noticably worse -- but still acceptable -- performance from when it was new. It equates to around four hours of continous, low-processor use with the screen brightness at 10%. -Dave |
