4 month old batteries won't stay charged long
I recently installed 6-6 volt US batteries in my Ez go about 4-6 months ago. After installation, the batteries would last for 10+ miles slite grade. As of now, I'm lucky to get 2 miles before they are near dead. What happened here????
(When I plug cart in, it charges for about half the cycle time. Batteries show full charge. I have 2 chargers and it does it with both). Thanks for the helpin advance!!!!!! |

Did you check the water levels?

Re: 4 month old batteries won't stay charged long
Which model batteries did you install?
Did you follow the break-in procedure? Are any of the cables/controller getting hot? What is your definition of a slight grade? As "MichaelClayshulte" said what are you water levels? What is you setup, controller/motor? |

Re: 4 month old batteries won't stay charged long
When you say 'batteries would last for 10+ miles slite (slight) grade', what does that mean? How far were you running them down? Do you have a digital voltmeter installed on your cart to monitor pack voltage?

Re: 4 month old batteries won't stay charged long
Your charger(s) might not be capable of fully charging US Battery batteries.
What is the Make/Model of the chargers you have used to charge them? Attached in a SoC chart for US Battery Deep-Cycle Wet-Cell Lead-Acid batteries. The voltage reading is taken 12 to 24 hours after the charger turns of automatically. Also what is the model on the USB batteries you have? |

Re: 4 month old batteries won't stay charged long
I am running US 2200 batteries (2015) I am using a power wise charger. All water levels are good and I have load tested all the batteries and all appear good. I have a 500 amp Altrax controller and a AMD-36 Volt motor (4.45 hp@3570 RPM)
