That guy in the Fico building on Asoke that calls himself DrMac is excellent, he's Eastern European I think, speaks good English and knows his stuff. Prices are good and he's quick. He replaced my MacBook screen one time, and a speaker too. Never had a problem since.
Two years sounds a very brief battery life, even given it might have been worked to death. I'd get him to check the Mac over, it's just possible there's another cause. I changed my battery two months ago (not with him, I'm abroad) after seven years use. It was still good for an hour to an hour and a half before being drained, and I used it on and off battery about nine hours a day.
