Car electrical guys - need battery upgrade advice

[Billy Goat]

I added a battery minder 2012 to my tool list and have been getting crazy life out of my batteries. I hit them with it every few months for a week or so.

Think it would work fine 24 hrs at a time? On a battery still installed?

Been looking for a trickle/maintainer for tractors.

Desulfation takes time...but I'm not sure how little time.

Bigger lead-acid SLI makes a real difference, and essentially zero cost difference between most sizes. I've hammered shelf edges flat on several vehicles and nearly doubled the capacity.
