I have a macbook air 11". I just got a new batter installed a few weeks back. I don't know if there is correlation here, but every since the batter was replaced, I have gone through 3 chargers. Why would this be?

I have a macbook air 11". I just got a new batter installed a few weeks back. I don't know if there is correlation here, but every since the batter was replaced, I have gone through 3 chargers. Why would this be? Is it that they installed the wrong battery? The charger I've been using is 60W. I believe one of the was a 45W. Does the wattage matter? I'm thinking it's related to the new battery because I never had that problem until I had that installed.
