I bought the IBM ultrabay slim battery. Do any of you have this battery. If so, what does it show as your full charge capacity. Also, has it happened that for some reason it didn't charge until you took it out and put it back in?

Thanks.

18.39 Wh after 81 cycles.
Design is for 23.76 Wh.

On the T40 I have, and others have reported this as well, the batteries will sometimes fail to charge until you remove and reseat them. This is possibly related to the latest BIOS + (power?) controller code.

14.34 Wh after 81 cycles
and it's only 5 months old. hopefully it'll konk out before the warranty expires.

Five months old and you're down to almost half the rated capacity???

I've got news for you, it's already "konked". Call IBM and tell them you want a new one!

Just got mine today from Insight.

23.76 wh, cycle 1.

If I can get 6 continuous hours on the pair I'd be happy.
