Re: (ET) Battery chargers.

This is exactly what US Battery requires... so for the 225 A-Hr US2200 
golf cart battery, a minimum of 22.5 amps is needed for the bulk phase 
of charging. Never needing watering is s sign of under-charging; 
requiring excessive watering is a sign of over-charging. The electrolyte 
should be bubbling nicely at the end of the charge cycle.
