Is there a way to hook up a battery maintainer if we don’t drive the car all winter? Car will be stored in our garage in Michigan.
Will this keep the main power battery charged?Yes, of course there is.
You get an automatic tender type small charger (NOT a trickle charger) and connect it directly to the battery.
Either to the posts on the battery or to the "jump points" under the hood.
Fuel stabilizer in the gas is a good idea too.
