Questions about this item
Does this 6-cell 10.95V 77.5Wh battery fit the A1286 15.4-inch Mid 2009 or Mid 2010 MacBook Pro chassis?
Yes, it is built for the A1286 15.4-inch MacBook Pro Mid 2009 and Mid 2010 models and matches part numbers A1321, 661-5211 and 661-5476.
The kit includes two screwdrivers — which screws do they fit and what is the common mistake?
The drivers fit the bottom-case screws and the battery’s three tri-wing screws; the common mistake is not disconnecting the trackpad flex cable before lifting the old battery.
After roughly 500 recharge cycles, what replacement will be needed?
The lithium-polymer pack itself will need replacement once it no longer holds a useful charge after about 500 cycles.
