Golf cart batteries
yes, JeffC_, you are correct with the 25% rule as it applies to wet type lead acid batteries. However, a smart charging regulator tends to make the rule obsolete as it regulates the current to the batteries. 25% rule is more for unregulated (or pooly regulated) charging plan. It would be a waist, though, to install an alternator with the capacity of 50%, as the regulator wil not let it run to it''s capacity. It''s all a matter of find a good balance between batteries/regulation/charging.
