Very impressed that this KZbin man takes the time to answer questions. Alot don't. Good for you. I don't have an electric golf cart yet, but may someday. Right now i came here because an aircraft tug vehicle with similar battery setup has taken a dive in a few months of non-use and coupled with weird extreme cold in the deep south. When I say extreme, I mean EXTREME ! January 2024. I'm confident your instructions will work great! Thank you

[@waynemartin.waynesgolfcart4900]

Great, Thank you!

[@kristineozment977]

Thank you so much for this

[@nebhosspin1252]

Thanks for showing as it is helpful. My golf cart is club cart 36 volts with 6 batteries. Will that also applicable if I plug in the charger, and the reading for 1 of the battery is more than 6.5v or less? My batteries reading without the charger are from 6.2 to 6.5 volts range for each. Thanks for help.

[@waynemartin.waynesgolfcart4900]

Your batteries are low. What I am saying, is when the charger is running, and 1 of your batteries voltage us twice as much as the others, then that battery is bad.

[@robertcoulthard7461]

Thank you Wayne. Of course, I ended up having to buying a load tester to find my dead battery.

[@salzero1]

Very informative video. I also have a ez go rxv. Bought it used and batteries are not lasting to long after a charge. Going to check if 1 battery might be bad of if I should just replace all. Thanks again.

good luck sir, i check mine, for overheating, you have to check current

[@caleclarkson7591]

Would a bad battery only let the cart barley move? Got a friends 36volt cart and if I slightly hold the pedal done it will move but not very fast. All the batteries test over 6 volt but one and it’s at 3.4. Thanks

[@waynemartin.waynesgolfcart4900]

Yes 1 battery will keep cart from moving.

[@robertomejiasmurillo4884]

Hi Wayne. Thank you very much for the video. I love your content. I have a question, is there need to be any special battery if I have to buy one? I am assuming you just need to find a 12 volts battery similar as the ones used in cars. Thank you

[@waynemartin.waynesgolfcart4900]

No, car batteries and golf cart batteries are not the same. You need deep cycle batteries and they are expensive.

I recently bought a used 2012 RXV and was wondering if you like and recommend your watering system that you have on your cart. I learned that back battery is a booger to fill up. Thanks

[@waynemartin.waynesgolfcart4900]

I am no longer a fan of watering systems, after seeing batteries blow up due to gas fumes getting trapped inside the hoses. My best advice is to install a lithium battery set up. Next, just the normal 3 in 1, or 4 in 1 caps that normally come with the batteries. You can easily reach those rear holes with a Hudson sprayer like I show in my video.

I have a 36 volt ezgo, time for new battery, been thinking of of with 3 12volts, do you loose in the way of distance and performance this way? Say with 12 volt marine deep cycle battery.

[@waynemartin.waynesgolfcart4900]

DO NOT USE MARINE BATTERIES FOR A GOLF CART!! they will only last 2 years max, and your distance sucks. If you have 6. 6 Volt batteries right now , totaling 36 Volts , and want to replace them with 3. 12 volt batteries you can do that but your distance will diminish because 6 batteries has more lead than 3. 12 volt batteries

Wayne thanks for this excellent video! I have a Club Car cart and it took 7 hours for a full charge. Only used it about 1 hour and it would not start so I charged it. 2nd time time it took about 5 hours to recharge it. It starts now but I must have a bad battery. Can you help me?? Subscribed! 😊😊🇺🇸🇺🇸

[@waynemartin.waynesgolfcart4900]

Your charging times sounds normal, nothing unusual. BUT if you can only get 1 hour of driving out of a charge, that might be a problem. Get a volt meter and check the batteries, before, during, and after charging.

do you have a video on how to change that bad battery ? i have a club car with one bad battery how to disconnect and connect it back? thanks

[@waynemartin.waynesgolfcart4900]

No video, none needed. If you need to replace a battery, being careful, flip tow switch to tow, remove the 2 cables going to the bad battery, and lift the bad battery out. Then drop in the new battery and rehook up the 2 wires. Just don't let the 2 wires touch anything or each other.

Maybe you have your tester probes on the wrong terminal. Mathematically doesn't seem possible,. Send me a picture of your entire battery compartment so I can see all the batteries and wires. Also indicate where you are placing your probes? Text the pics if easier 760 393 1314

[@usasupra23]

I didn’t know you could test them while they were still connected in series? Do you also need to load test them as well to be sure?

[@waynemartin.waynesgolfcart4900]

you can test them while they are still connected, also can charge individual without removing any wires.

[@usasupra23]

For us basic battery users, should we be moving the battery positions in the rack periodically at all? I was told to move them once in a while

[@waynemartin.waynesgolfcart4900]

No, no need to move them. I never heard that, why lift those heavy batteries at all.

[@davegervais8306]

When testing voltage on individual batteries , do you disconnect the main ground to the OBC and the main power first? Do you disconnect all the batteries or simply put the negative and positive leads of multi tester on the positive and negative posts of each battery.

[@waynemartin.waynesgolfcart4900]

don't need to disconnect anything. Just read each individual battery and then the entire pack

I have a 48v cart -4 12v batteries. Put the charger on and the meter only came up halfway. Put battery tester on - all showed good under load. Put the charger on another cart and the meter went to full charge. Any ideas?

Did you try another charger on your cart?

[@steelwheels4613]

No I haven’t. What would that tell me?

[@waynemartin.waynesgolfcart4900]

If both chargers worked the same on both carts, then that would there might be something different about your cart. There may be no issue at all with your cart, if the batteries are fully charged, and charger is acting that way.

[@bradytom78]

Thanks for this video. My EZGO txt only lasting about 9 holes and really struggles on uphill. I've checked my 6 batteries at full charge. All measuring 8.6V. Should I measure again when the cart is nearly out of power?

[@waynemartin.waynesgolfcart4900]

Check volts on each battery and also on the entire pack, check them twice, charge them and let them sit for about 6 or 8 hours or more. Then drive cart for awhile and recheck all over again, then let's compare the numbers.

[@bradytom78]

Have you thought maybe whatever you are calling an indicator might be bad?

[@bradytom78]

@@waynemartin.waynesgolfcart4900 I wish that were true. The power is definitely down when indicator says so, once indicator gets to 50% the cart can barely make it up any upslope. Cart in question is ezgo txt 2+2 from 2018. One thing is one of the batteries measured 5V at first, but when I rechecked it was 8.6. This happened twice. Once at full charge, once after running down a bit.

If the batteries ever get to 50%, they are considered dead. How old are your batteries?

My batteries are jumping from 0 to 18v when plugged into the charger. Charger light is on on the charger but doesn’t show it charging light when plugged in. Have 6 12v batteries

[@waynemartin.waynesgolfcart4900]

Some things don't sound right here. First if your batteries are at zero volts, they won't trigger your charger to Come on. And if you have 6 batteries at 12 volt each, that's 72 volts. Exactly what type of golf cart do you have? When was the last time the cart was driven and last time it was fully charged? How old are the batteries? You can send me pictures of the charger and the entire battery area so I can see all the batteries and wires.

Can a battery be restored ?

[@waynemartin.waynesgolfcart4900]

Not really. Not sure what kind of battery you are talking about, but if it has gone dry and the plates exposed, it's a gonner.

[@derrickdry504]

Is it okay to change out just one battery? I’ve heard you should change them all at the same time.

[@waynemartin.waynesgolfcart4900]

Here is my answer, I would say if the set of batteries are all the same age, and are 3 years old or more, then change all at the same time. Anytime you only change 1 or 2 batteries only, the remaining batteries will pull the new batteries down to their level. Therfore the new batteries will have their life lessened. Now if your set is say 2 years old and 1 battery goes bad, then yes just replace that battery. And if you do, try to find a used battery about the same age, or if not , you have to buy a new one.

[@waynemartin.waynesgolfcart4900]

Not following you? You want to see the charging on only 1 battery? If you have a set of 8 volt batteries, you can check the individual batteries with a volt meter.

[@jremeee2011]

How old are those US batteries?

[@waynemartin.waynesgolfcart4900]

2 years old. The reason the battery went bad, was because the charger was set for the wrong algorithm.

[@johnliebe1234]

I use cleaned and tightened all my terminals. Without the charger connected, there is about 48 volts across all the batteries. When I connect the charger, the charger meter goes to 15 amps and stays there. That doesn’t sound right to me. Suggestions?

[@waynemartin.waynesgolfcart4900]

Sounds like it is working correctly. Leave it plugged in, in about an hour the meter should drop to around 10. Just leave it alone , don't unplug it. If charger is running after 16 hours, then you can unplug it.

[@johnliebe1234]

Thanks. That worked. Is it ok to leave the charger plugged into the cart all the time? Does it matter if the cart is in Run or Tow?

[@waynemartin.waynesgolfcart4900]

no, doesn't matter, run or tow. As long as there is water in the batteries, you can leave the charger plugged in
