The battery of my MacBook Pro 15" (early 2011) died recently and I happen to have the battery from a 13" MacBook Pro (2010) handy.
Does anyone know of any reasons why this battery would not work?
I'm not concerned about battery life – I just want to be able to power the thing up.
Any ideas?
Thanks!

Nope. They're different sizes. Compare iFixit's guide to replacing a 15" early 2011 battery to their guide for a 2010 13":
15":
13":
Both batteries are roughly proportional to their cases, and the 15" has a substantially bigger case than the 13". Additionally, they're shaped differently - see the little notch in the top left of the 15" battery, which isn't there on the 13" battery. It physically won't fit.
