OS X 10.2.8 PB 17"
Ever since I applied the battery update, my battery "time left" readings are all over the place. For example, in the span of one minute I see the following readings:
2:29 3:15 2:49 3:22 2:59 2:40
the percentage readins don't appear to be changing. I've been thru several recalibration cycles.
One top of this, and even more irritating, I no longer get a low battery warning at around 10%. Instead at about 18% the machine just goes to sleep with no warning.
Did Apple screw up yet another update release?

Mine works OK in that respect... Very accurate estimates after a brief period of optimism.

..but I do see that one. It sits there saying calculating... for about 5 minutes and kerplonk!.

ever so slightly it would seem.

Hmm, finally got around to trying the spare battery with the update. I purchased this battery last month. With this battery in place I get the low battery warning around 7% and the powerbook goes to sleep when the reserve goes down to 2%. Still with the original battery that came with the machine (purchased May 2003) I get no warning and the machine is forced asleep around 16 - 18%. This is repeatable.

Have had the same post battery update experience with the original battery in my PB G4 FW800. Dodn't get a low battery warning and in my case the comp goes to sleep abruptly when the battery level has reached around 20%. This never happened prior to the update. The two times I did calibrate the battery,I got the 10% warning clearly suggesting that this is indeed an update issue.

It's been fine for me, but reports at Macintouch are bipolar. Some people think it's great and others have your experience. Very little "ran fine but didn't really have any significant impact" comments.

Prior to installing the battery update, my 1.25 GHz 15" AlBook was getting less than 2 hours. ioreg showed the capacity as 3318.
Right after installing the update, capacity shot up to 4200 and I was able to get around 3 hours out of it. But over the last couple of days, capacity has come back down to 3568!! Ugh! And I'm getting quite a bit short of 3 hours.
Anyone with similar experience?

If you have not calibrated your battery in a while, "20%" may be an incorrect estimate of the charge. Perhaps it was really only 10% or less? The way to be sure is to calibrate your battery before running the update.
And I recommend calibrating it at minimal load, FWIW.
