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.

Batteries should generally be bulk (up to 80% SOC) charged at a minimum rate of C20/10 - that is, ((20-hour amp hour capacity) / (10 * hour)); e.g. a 240 ah battery should be charged at an initial bulk rate of 24 amps. And there is ^almost^ no upper limit! As long as temperature is monitored, a battery can accept charge about as fast as it can be discharged (that is, until it's 80% charged). Several experiments have shown that batteries actually perform better when charged at these rates for at least part of the charge cycle.
