Batteries test fine, cart will not charge

donnapaula

We tested the batteries they all seem fine, but when we put it to charge, the charger stops at 10 and the cart is NOT charged, are we missing a piece to this electrical puzzle, please help I posted 3 days ago and NOONE responded...when you first get in it it seems fast then slows immediately...It's a 2004 EZ-GO 36V

Hello, sorry nobody responded...... please explain the charger stops at 10? DO you have a volt meter? If not borrow or buy a DVM. check the total pack voltage before and then after you plug the charger in ... what are the readings? How long does the charger run? Any other tech info? Battery brand, age etc?

Thanks Scotty, actually we just put brand new batteries in, we charged it fully and it's still doing the same thing, it's going a little faster but not much, it almost seems like it goes faster in reverse...This time when we charged the batteries it seemed to take a full charge, before the meter would get to 10 and then get hot and shut off

Do you have a voltmeter?

NEW BATTERIES?
http://www.buggiesgonewild.com/elect...attery+Breakin

NEW BATTERY BREAK-IN PROCEDURE:
Following proper break-in procedure can increase the strength and the useful life span of your new batteries. New batteries are initially about 75% of their full strength. The following procedure will insure they reach their full potential.
The 1st 10 to 20 complete charge/discharge cycles are critical to insure they reach 100%. New batteries should be charged before use and thereafter as follows:
Plug the charger in and leave it alone until charger shuts off by itself. Then drive to discharge the batteries to 75% battery pack capacity (see chart) Plug the cart back in and repeat the charge cycle.......It is very important you let it charge until it is completely done. Repeat this for the first 10 - 20 cycles......by the 12th cycle you will notice a difference in power, speed, and run-time.........I have never had a customer say they have not noticed the increase.
Most importantly, NEVER run the battery pack down below 50% of capacity throughout their entire life. Never leave the batteries in a state of discharge for extended periods of time. Recharge the pack once a week if the cart is sitting idle or in storage. And when in doubt, recharge it.
During the break-in procedure, keep an eye on the water levels. T can take 12 hours or more for the 1st few Charging times. These extended charge cycles may evaporate some of the water. ( use distilled water only )
As the batteries break in you will notice the charge time gets shorter. Eventually going from 12 to 5-6 hours per recharge.
ONCE A MONTH:
Routine maintenance is the 2nd most important thing to insure you get the most use out of your new battery pack. It is critical that you get into a routine of spending 10 - 15 minutes a month to keep the cable connections clean and check the water levels. Proper water level is critical. Dry batteries die quickly.
Keep the Distilled Water level up to the bottom of the fill hole sleeve or a half inch above the lead plates. Do not fill to the top.
Use a hard nylon brush to remove any visible corrosion. Carefully check that all of the cable connections are tight. Loose connections cause arching which will melt the soft lead terminals. Spray-on Battery Terminal Protector is available from the auto parts store and greatly reduces corrosive build up.
I hope this helps you get the most use possible out of your battery investment.

we do have some sort of yellow meter that we originally tested the batteries with

scottyb

The yellow meters are good What is the pack voltage?

donnapaula

I'm sorry what does that mean, they are 6volt batteries

scottyb

The pack voltage is the sum of all the batteries hooked together. It is what the cart runs on... 36v or above. A pack voltage reading is an indication of state of charge. A reading before and during charging would show if in fact the charger is or isn't working.

donnapaula

He is going to test that, we checked a couple more wires that didn't look great and have put it back to charge
