our cars can't run without a car battery, so this has to b car related, i have 5 batteries in a setup against the wall for the winter, i use a trickler system, maybe u have seen them from harbor freight??????????, i was checking the batteries and found 2 of them to be up around 17 volts, the rest were at 14 or so, when is high to high??????????, thanks jerry
I'd say 14 v on a trickle system is about it. Just my opinion though...
