Also, the controllers in some carts are on all the time, unless the Run/Tow switch is in Tow. Plus, so cart have voltage reducers for 12V accessories that stay on all the time. So the question is: How much do the batteries discharge over what period of time? |

Re: batteries discharge
Also define "fairly new", how often do you charge, and how often do you check electrolyte?
How do you measure voltage, handheld, onboard voltage meter, or bar chart? |

Re: batteries discharge
Battery age is about two years. Use cart every day for golf. Charge every day. electrolyte - monthly. Hand held voltage meter.

Re: batteries discharge
Batteries acquire a "surface charge" while charging, so the voltage measured immediately after the charger shuts off will be significantly higher than what it is a few hours later.
A 36V pack will measure about 45V or higher at charger shut off and about 38.2V about 12 hours later. |
