Battery help

[JS3]

I am looking to buy a new battery for my Early 2011 15" macbook pro. My current one is saying service. Where other than apple can I pick one up for a decent price and what are the specs I should be looking for.

Thanks for you help.

I wouldn't trust or recommend any non-Apple battery, due to the number of problems reported with "knockoff" batteries. Also, there is no assurance that knockoff batteries have the same charging technology that Apple uses, involving the battery, the MagSafe adapter and the Mac's logic board.
