Input: After reading the reviews I had high hopes for this replacement battery.  It fits well, charges up and does not get hot.  All is well until battery level is around 30% then it drops like a stone.  Battery was at 33% this evening.  I left the room for literally 5 minutes and when I came back in the laptop was completely dead.  I booted it back up with the power cord plugged in and the battery had completely drained.  I had calibrated the battery as instructed. Also, the battery capacity dropped from 100% to 96% the first day I used it.<br /><br />This is the second off-market replacement battery I have tried.  I have learned my lesson; I guess I will have to pay Apple's ridiculous asking price for a new battery.  Very disappointed.

Didn't work for me
