I use a Schumacher SEM-1562A charger 'Maintainer' for my SUV battery, but it doesn't have a desulfator function.
I don't drive it much anymore. If we don't need to haul big stuff, we take the wife's Prius C2.

We replace car batteries every 6 years, so I'm able to cycle out my old junk 12V basement batteries.
When I buy a new car battery (we have two cars), I turn in my oldest 'basement' battery.

My 12V solar controllers are simple voltage regulator junk from China.
They were cheap and they don't over-charge, so I'm happy..

My next big battery problem is to replace my three year old 48v battery bank,
with real solar backup batteries..

I'm not sure, but I may have set the controller voltage too high and
lately the output performance has dropped off..
