battery meter question

lspencer001

I have a 1998 Yamaha G19E. when I bought the cart it had 6 brand new interstate deep cycle batteries in it. I wanted to keep them in good shape so I ordered a analog battery meter from the dealership. when it came I installed it and it went straight to the charge section on the meter and when you plug it in to charge it goes to the red section. I know that when I put the volt meter on it reads right around 50volts after a charge. is this normal for new batteries or is the meter itself defective. thanks

thanks. that helps out greatly. just went out and measured and after a full charge they read 52volts.

FYI
The charger cut off point for most 48v chargers is about 63 volts. Once the charge has ended the batteries begin to settle. this settling takes 12 to 24 hours. At that point you can see what the batteries can hold. Ideally that is 50.9 v
Your 52v may still be going down

ok thanks. now another quick question. my cart also has the digital foward/reverse switch on the dash. some people have told me to always turn the key off when not using to avoid draining the batteries and others have said that it is not required.

If you leave it on for days or more on end, it will drain. If you forget to turn it off until tomorrow it may drain a little, but not totally dead. The cart turns itself mostly off when the relay clicks off a few seconds after you stop driving. I have accidentally left them on over the weekend, without any trouble. Sure, it will drain "faster" if you power the logic circuits on for long periods of time without need to do so, but we are talking a few milliamps (1 milliamp = .001 amp) difference here. Some logic circuits are active all the time anyway, (with tow/run switch on) go unlock the brakes with the key off, and try to push it out of the garage, it will fight you all the way. If it doesn't, your motor rpm sensor is not working.

ok thanks. I always turn the key off every time I get off even if for just a few seconds. did the break test and it didn't want to move so that is a good sign.
