Winter Prep for a rig

[nate379]

I wouldn't think a trickle charger would damage a battery. If your rig is always needing the charger, I would guess there is some sort of draw the charger is covering up, or the batteries are junk.

Batteries are supposed to only last 4-5 years.... that being said, the ones in my truck are about 7 years old best I can tell and they work great.
