Of course they are perfectly normal. > > what would be an accurate description of > the good battery (good, great, super, so-so, odd, etc?). If it actually lasts 2 hours and 15 minutes, I would describe it as unbelievable. In fact, I don't believe it. The Battery Time Remaining on the classic Mac OS is notorious for grossly overestimating the actual battery life of older batteries. It probably died out much sooner than that. > > Is there another > battery program that I might try to reach the dead battery with?

TIA One may have been heavily used, the other not. I don't think they're as far apart as you suspect. Actually run the PowerBook (and use it) on battery for as long as that battery lasts. I bet its less than an hour. I wouldn't be surprised if it was under a half hour. -- PowerBooks is sponsored by <http://lowendmac.com/> and...
