Slow charging at 1 or 2 amps or less does a better job than fast charging.
I keep all my vehicles on battery tenders. Those all charge at a rate between 750 mili-amps to 1.25 amps. They turn off when the battery is fully charged.

I know a lot of folks that use a battery tender to maintain the charge on their battery and never disconnect the battery cables from the battery.

That includes vehicles, boats and yard equipment and I’ve done it that way for more than twenty years, with no issues.

BTs maybe not. I dont take chances. If its being stored , battery is disconnected anyway.
