Battery

kantuckian

I have a 2000 CC DS with 4 12 volt batteries they are napa less then 6 months old.I charged them and they read 50.6 volts after charging ran a discharge test and the discharger ran 42.3mins,restarted discharger 3 batts read 12.0 0ne battery reads 10.3 volts.started charging again the bat that read 10.3 volts reads 15.4 volts all others rearing around 13.7 volts, I check them like every 30 min ea time readings differ between ea battery .my question is does anyone know why all batteries are not charging equally. Note this cart has 6 ga cables non like any i have ever seen if they are for automobiles would that have any effect on charging thy look like new and very good.

I'm guessing you have automotive batteries and not deep cycle golf cart batteries. Or marine batteries what are the markings on the battery.

NAPA #8141 ser#505962 BCI #GC2 77min @75 Amps that's it all it shows on Battery label.

Thanks

That's a golf cart battery but with the voltages that one is reading there is something wrong with it. I have an Interstate battery for my riding mower that started doing the same thing; found it flat one day and it charged to well over 14 volts. I let it sit for a while and then plugged back into the tender and it started stinking the high heavens...

I guess my guess was wrong. But whenever I see NAPA I think car battery. Still don't know. Nowhere do they say deep cycle battery just golf cart battery.

It does say dwn on side of battery for GOLF Cart

Just a thought, is there any chance you are using one of your batteries for 12 volt accessories like lights or a radio? If so, that could cause some imbalances in charging.

How does it run when your finished charging?

They were using the battery that read low for accesories they left it unattended for a couple months with radio left on competely drained that bat.i installed a 48 volt t0 12 volt reducer then charged the batteries only ran 40 plus minuets same battery checked bad like shows 2.0 volts less then other 3 the owner said that bat had been replaced 3 times Question the other 3 batteries r 2015 batteries would it work if i just replace that one battery

Considering the cost for 4 new batteries to replace batteries that are less than a year old I think I've be willing to just replace the 1 that is not behaving as it should....
