I bought this on another recent sale. Didn't like it, so returned back to Amazon. First, it couldn't repair a battery that has apparently died sitting in my car that wasn't driven in a few months, even after left plugged in for 3 days. Second, it made a constant humming noise, that while faint, irritated the hell out of me. Third, the unit looks cheaply built, with thin cables and clamps that are rather too small.

That "Repair" button is for low voltage ONLY; not for desulfation .... When a battery is discharged so low that THIS charger will not engage, it trickle charges to bring the voltage back up to where this charger can engage.

I bought this on the deal a few weeks back. It worked great to bring my completely dead car battery back to life. Now I can start/drive without having to jump the car everytime.

I had to use the low voltage repair mode.

I'm kinda excited about this model because it claims to have a desulfator to 'repair' older batteries. Might have to pick it up.

It should unless it's a lithium one. This charger should be able to handle most types of lead ones (deeps cycle or crank one)

Maybe.... not for gel or lithium batteries, but will work as a maintainer for a deep cycle lead acid Marine battery that simply has the plates further apart for the ability to be drained completely and recharged numerous times.

This is not a hands off charger.... if the voltage is too low from being drained, you will have to use the "Repair' function on this charger to bring the voltage back up to about 7 or 8 volts before the charge part of this charger will work.

I think I remember an old superhero cartoon where the villain had a desulfator and was out to harm man kind with it.
