Battery finally clicked its last click. After months of trouble with it it finally quit. Threw a nearly brand new Everstart U1R in as a temporary fix, and I have a Deep cycle one laying around that no one’s using yet. Any reason not to use it as a supplement for that poor lawn mower battery? Especially for basic tasks like running the blower fan for a few minutes while the car’s not running or rolling windows. I have old wiring ran for an amp I used to have, no reason not to just put the deep cycle onto those wires? I know I should just get a real car battery but money’s tight and I want to get by with what I have for maybe a month, if that
