It's best to have dual batteries with Battery Isolater or an upgraded alternator. The H2 has a pretty stout alternator to begin with. Rule of thumb is always leave engine running and if you dont have either of those, you should winch for a bit and stop so alternator can rechanrge battery. If not, there is a chance you can overload alternator and burn it up or kill battery or both.

I think Summitup is ahead of the game with dual batteries. I just take the cautious approach and winch slow, pause and winch again.
