100A would only be delivered to a flat battery, it'll charge much slower than that.
There's also the parasitic loads to make up for, the electronics that eats power when the vehicle is off and on.

You're better off testing battery voltage and not doing anything until it drops enough to warrant charging. Leads acids don't like sitting even half discharged, keep it near full.

We agree.
o Adults easily agree on such things simply because they are related facts.
