New iFixit Battery draining quickly after install
I recently purchased a NEW battery for my MacbookPro 13" (early 2011 i7)and after install, the battery seems to drain very quickly. I initially let the battery drain to 5% and then connected the magsafe charger and charged it to 100%. In an effort to see if the battery was performing correctly, I unplugged it and used it for about 30 minutes. The battery dropped quickly from 100% to 92% (within 3 minutes) the estimated time remaining on a the charge was 5h42m. It then declined rapidly after that until I decided to plug it in again. Is this normal from a new battery? Am I supposed to do anything to make it work more regularily? any help would be appreciated.
