I don't disconnect the battery cables on mine (Generac GP7500) when the
trickle charger is on it.
However, I do disconnect the charger when I do the weekly test run.

hello everyone,

I just bought a used generator (excellent shape) with elec. start.

What I'd like to know is ...is it necessary to disconnect either of
the cables to the battery to charge it with a trickle charger?

Thank you for advice and information.
