Not sure why it burned, but I'd expect the other motor to go also if
it's a matter of you doing something wrong. Knowing if the motor
really draws more current from the new batt would be nice as would
the temperature rise.

Aside from that. AFAIK, lawn mower batteries are not made for deep
cycle use. Maybe the batt revolted :) Maybe someone at the toy mfg
can tell you more about the original batt. Beware of salesmen.
