What experience do people have with 12" PB batteries getting crappy long before the 300 cycle/80% point? Does Apple replace them (mine is still less than a year old)? Or do they just ignore it since the Powerbook itself is no longer under warranty? (they refused to fix my loose power connector because of a small dent on the bottom-right corner from the first week I owned it). Apple seems particularly obnoxious about fixing the 12" Powerbook (since friends with 15" PBs have gotten them fixed even with visible damage), but I really can't afford a new battery for this old machine (saving up for a 15" MBP!). My battery is, as stated, at 21% health after 257 cycles. It lasts maybe 30 minutes. This is down from more than an hour only 4-5 days ago. Is Apple likely to replace this?
