Sorry I don't follow. What was dead, the charger, battery or winch.


The battery ....



I see no issue with using one charger for 2 batteries. A charged battery
on a float charger should take very little current.

On previous years charged each fully individually then put them in
parallel and hooked up charger and left it on over winter and all was
fine ... this year the one battery was flat.

Maybe I had a bad connection but all were in place OK
