Could charging of battery while not disconnecting it has caused the problem in the engine of Sears garden tractor?

I have a 2008 sears garden tractor with a 25 hp courage pro engine. I changed the oil and charged the battery because I left the key on. Now the engine starts but will not stay running. Oil is full. But I did not disconnect the battery when I charged it. Could this have done something? Could charging of battery while not disconnecting it has caused the problem in the engine of Sears garden tractor? I would really appreciate your replies regarding this. Thanks.
