Replacing the battery was not likely the cause of your check engine light. Most auto parts stores have a code reader will read the code for you at no charge and reset the light.
Most likely the alt. quit. The battery ran out of charge. Charge the battery, start the engine, and check volts on the battery, anything less than 14 volts, like 12.3 or so, check wires, and most likely change the alt.
Only the computer can tell what made your check engine light come on. It could be your battery. If your battery is bad, replace it and see if that solves the problem. If it does not, then you will have to connect your car to the computer and find out why the check engine light came on.

My check engine light came on because the terminals were not connected tightly. no. quite the contrary. if you have a "check engine" light on, disconnecting, or in this case replacing the battery will turn it off. you have a different problem.
locate the x fuse in the engine right side test it
If it does that. Check your alternator. If you have no problem there. Check your battery charge. I'd check the battery charge first. If thats cool. I'd check the sensor. Cause it's telling you somethings wrong with your battery system. Good Luck.
