Testing Batteries on a 36v

papajoe · 05-23-2010, 06:10 PM

First let me apologize if this information existed. I searched and searched and my lack of computer skills may have caused me to miss these intructions. How do I test my batteries to see if they are all good? I have a 2008 EZ GO with the forward and reverse on the dash. I think it is a PDS? Anyway I want to know how to test the batteries please.

Your cart is 2 yrs old. Do you have reason to believe your batteries are not good? A voltmeter and hydrometer will give a good idea of the general health of the batteries .... beyond that is a load test .

Here is why I say I am concerned When I left to go out for a spin in the neighborhood the bettery meter on the dash read full. I went about two miles and teh weight in the cart was about 380 lbs of passengers me and one other. We were crawling up hill. I get back and the bettery meter reads a line above half. BUT! When it gets to a flat surface it has pull. Just really never knew if batteries were ok. Last time me, my wife and toddlers were out no problem at all. Thoughts?

You may have a weak or bad battery?

Thats what I am thinking Scotty but how do I test it? I am a novice at all this. I just got the cart 2 months ago. Could you please instruct if you wouldn't mind. Do I need to purchase something?

Ok I figured out how to test batteries one is reading at 5.9v the 5 other are either 6.1 and 6.2. Should I replace the 5.9?

If you are sure you have 2 year old batterys that are going bad you dont want to replace only the bad ones as that will cause damage to the new ones by over charging them. I know its alot of expense but when changing batterys replace ( ALL ) with new ones with same date code and be sure of not having some with older shelf life .

Yep replaced them all. Now getting 6.2 on all batteries..

Be sure to break the new batterys in correctly. Look at stickies above for info.
DO NOT RUN CART UNTIL AFTER CHARGING BATTERYS FIRST.
