Default Expected Voltage Loss?

It seems my cart loses about 50% of charge over two weeks (Lester Summitt II plugged in all the time). Is this normal? It is a bit annoying because when I need to use it I have to go start a charge.

Default Re: Expected Voltage Loss?

Lead-Acid type Golf cart batteries tend to self-discharge at about 1% per day(more or less), so in two weeks they'd typically be down to about 84% (14% loss).

A 50%loss in 14 days indicates sick batteries or something is draining the pack.

The Summit-II charger shuts off after the charge cycle, so it doesn't matter if it stays connected or not.

Yes - that is normal. I don't think the Lester will restart charge without unplugging it. Maybe I am wrong about that but I have not used mine since I switched my cart to Lithium.
