I have a 2002 PDS cart with 2008 Energizer batteries in it. It appears to charge fine by the state of charge sheet floating around and it passes a load test. I get around 12-15 continous miles around the neighborhood wich is quite hilly. My question is my powerwise charger will only run for about 4 hours after the batteries are discharged to around 50% and the big mystery is the charger always shuts off around 10 amps, which I think is to high. I would think it would go to at least 5. I do not think it is getting a finishing trickle charge. Can anyone running this type of charger tell me the amps their charger shuts off, and if anyone knows why mine appears to shut off early, your info would be greatly appreciated.
