How To Test Golf Cart Batteries For Load With Troubleshooting For Problems. Wonder how to know if your deep cycle batteries are good before you replace them?
This video below will help you follow a step by step to testing your standard, flooded type deep cycle batteries. Note – Gel & AGM type batteries are sealed and can be tested with voltage and amps but the electrolyte is not designed to be accessible so never remove their caps.
Tools needed for the VACE formula:
A. Standard volt meter
B. EZ Red (preferred) Battery hydrometer – offered on Amazon
C. Battery Load Tester – also offered on Amazon
D. Safety glasses
Open Circuit Voltage OCV
2.1 Volts Per Cell (VPC) = 100% Charged
1.75 Volts Per Cell (VPC) = 0% Charged
Specific Gravity S.G.
1.265 or Greater = 100% Charged
1.225 – 1.230 = 75% Charged
1.185 – 1.190 = 50% Charged
1.140 – 1.175 = 25% Charged
1.125 or less = Discharged
Always use hydrometer at end of charge cycle to check % charged.
