I routinely connect two completely different batteries together to charge (both 12volt, one lawn tractor and one marine). I NEVER leave them connected together for longer than I am charging them, and usually for durations around 24 hours. If I'm pushing 10amps into both, then I don't worry about one draining the other, then it's just a matter of pulling the charger and the jumper wires.
