Batteries seem to be failing prematurely

thompson521dc · 04-12-2017, 11:23 AM

I bought a new set of interstate batteries 13 months ago. I have kept them watered and kept cables tight. I have an in dash volt meter from Scotty. Recently (within last 8 weeks) the day after a charge resting voltage is between 50.0-50.3, it used to be 50.9-51.1. So based on the chart that is frequently posted here I am only getting 80-85% charged. The batteries have an 18 month battery. I went back to the place Ali bought them. I could tell the lady decided my batteries were fine before I even unloaded it. She used a handheld tester and told me they are fine. I explained what I stated above. She tried to say my volt meter is unreliable. I disagreed but the other thing she said the caused her to lose credibility is that I have nothing to worry about as long as they're over 48V. NOT ACCURATE! At this point I saw no point in arguing so I packed up and left. My first question is should I see this much deterioration in 13 months? If so my next question is does anybody have any experience dealing with interstate on warranty issues? Thank You in advance!

I don't know about interstate batteries. What kind of charger are you using? Have you reset the OBC?

Are they 12, 8 or 6 volt? and which model number?

They are 8 volt. Not sure the model number. I have not reset the obc. I am using the stick charger. It's a 2013 Precedent

What is a stick charger? did you mean stock?

The dash mounted volt meters can give false readings. You need to check pack voltage and individual battery voltage with a digital multimeter if you can find one.

Obviously I meant stock. (Big fingers, small phone)

Multi Meter and dash gauge are pretty darn close. Each battery is consistent 8.32/8.33.

That's after charge complete and 8-12 hr rest? You are using the factory Power Drive Charger?

Dang, I'm not an expert around here but it seems like you are not getting a full charge on your batteries...

Have you tried resetting the OBC? Pull the Neg wire from the battery post going to the OBC, leaving it disconnected for 15 min?

How much has the cart been used in the last 13 months and what do you use if for mostly?
