-- (1) Deep cycle. -- (2) New Batteries didn't run the cart, since installed. -- Update -- The service Man told Me that I didn't give the charger enough time (11 hrs.) to do it's thing, with new batteries. -- I plugged it back in - went shopping, and when I returned, after a few hours, the charger was off. -- Since then I ran the cart for approx. 1 hr. - plugged in the charger, and it worked properly, eventually it shut off. -- To sum this up -- I had 4 of 6 bad Interstate batteries. -- I replaced them with 6 new, U.S Battery Co. batteries. -- All batteries are 6 - 8 volt = 48 volt total. -- Looks like - problem solved. -- Thanks to All, for Your input.
