I bought a maybe-OEM battery on eBay for my recently acquired Pismo PowerBook G3.
It works great - I get like four hours on it with Airport off and brightness down in both OS X and OS 9. However, in OS X, it never seems to calculate how much time I have on the battery - the menu bar icon indefinitely shows "(Calculating...)". Additionally, Coconut Battery provides this information:
Battery Health Monitor is unable to read anything from the battery.
Is there a reason why this is happening? It shows usable time remaining in the Control Strip in OS 9, so something is off in how OS X specifically is seeing the battery's data (I think).

Have you tried reconditioning? Run it until flat, then charge it right up.

If you're getting 4 hours of battery time with airport off, then it seems like CoconutBattery isn't able to read the battery sensors on your eBay battery. You can throw that software away...especially for that old a model...
The other possibility is that the after-market battery never had the sensors to begin with.

I'm not sure the originals reported all that much info. I really don't recall.

Well, it's an OEM battery, so I doubt the sensors are nonexistent.
I know that Battery Health Monitor is pretty old; wasn't it around back in the 10.2 days? ...That being said, I suppose the Pismo is even before that time. I seem to recall the TiBook was the first PowerBook to ship with OS X.
As far as cycling the battery - it's already drained a few times since I got it, mostly due to me forgetting to charge it.
