Battery fun...

"desulfation mode"....snazzy!

Right?:D
Everything about it was automatic and worked like it was supposed to.
All I had to do after a trip as far as batteries went was to plug the motorhome in when we got back and it charged then maintained 4 big 6 volt deep cycle batteries.
They advertised as "Clean DC sine wave" meaning electronic equipment calibration quality power output.

Car show cars with hydraulics and big stereo's use them at shows to keep their power up, and golf cart owners love them for their cart batteries.
