Battery Saver

Does anyone have one of these? Does it work or worth it?

Mostly overkill IMO.
Your cart will automatically go back into a maintenance charge if it is left plugged in.
When the cart is stored, plugging in the charger once a month is more than adequate to keep your batteries in top shape.

i don't have that one... but i have used a charger with similar technology to "revive" 12V lead acid batteries.

from what i can tell, pulse desulfating does appear to add life to a heavily sulfated battery.
black line is a 5A discharge down to 10.5V after a normal charge.
red line was the same 5A discharge after 2 weeks on the desulfator.
green line was the same discharge after an additional month on the desulfator.

The aircraft industry uses desulfators and I'm sure they work, my question is whether it is practical for a golf cart that is regularly maintained and charged.
Each time a ferroresonant golf cart charger finishes it's cycle it spends about 3 hours in the equalization mode at 2.6v/2.7v per cell which should eliminate any sulfation that may have been forming.
