The old battery on my 12 inch Powerbook has only 10 minutes of battery life per cycle so I decided to buy a replacement. I've ordered replacement batteries for pre Unibody Intel macs and I've had success so I didn't really expect anything to go bad. Arrived today and I excitedly put it in only to notice something odd. It (kind of) doesn't work.
The charger changes from green to orange and the battery goes from being 0% to reading fully charged. Even more odd I turned on CoconutBattery to see that the maximum capacity of this battery was 65535mAh (obviously not true, it's just showing the highest possible number). Then it goes down to 6% out of 65535mAh which is what it should be. Then it shows 0 capacity with 0 charge. Then it goes back to being fully charged with 65535mAh, and the whole cycle repeats.
Disconnecting the charger I get like 10-15 seconds worth of backlightless battery life. I tried resetting the PRAM, PMU and NVRAM and it's obviously not a problem with the machine. The DC In jack works because it charges the old battery just fine. It's just this new battery I'm having an issue with. I wouldn't really care what capacity it showed if it actually powered the machine properly. Anyone had this issue before? Is there a way to recalibrate it? Should I just return it?
Edit: Seems like the 65Ah capacity is a common issue but those people still have running batteries, I can't get mine to charge up at all pretty much.
