How does your MagSafe power adapters cable look like? Does it have any bumps, kinks or worn spots in the sheathing?  You could have damaged your systems charging logic within your system. Stop using it and get a new unit.

Otherwise, when you change out the battery you need to do a few things here before using the system. First you need to do a SMC reset so the system forgets about the old battery. Then next thing here is to properly calibrate your battery. Follow these links:

I would also recommend installing this app so you get a better view on what your systems battery: [http://www.coconut-flavour.com/coconutbattery|coconutBattery]. Post a screen shot before and after you do the SMC reset and calibrating in your question so we too can see whats happening.
