This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries batery.repair and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!
Great production! I mean the way you put this video together. Really impressive with the illustration outlines inserted. I don't need to look further. Outstanding!
This video provided the practical solution I needed to get my Bad Boy MTV charging again. Thank you!
I seriously wait for these videos. Making a “Papas Treeclimber” myself, and these videos help out so much! Thank you!
There are several factors in battery repairing. One resource I discovered that succeeds in merging these is the Magic Mender Wizard (google it if you're interested) definately the no.1 course that I've heard of. look at this incredible resource.
Useful information used to overcome my problem many thanks
Straightforward and to the point. Thanks
Not certain about the points made but ,if anyone else trying to find out how to recondition old batteries at home try Bablim Battery Booster (just google it ) ? Ive heard some pretty good things about it and my co-worker got great success with it.
THANK YOU!!! THANK YOU!!!! THANK YOU!!!!
You saved us a TON of money!
Perfect info! Thanks!
Thank you so much! My golf cart was beyond dead and you helped us to revive it! Amazing video, super helpful.
interesting points ,if anyone else needs to find out about lead acid battery reconditioning try Jons Mender Guide ( search on google ) ? Ive heard some awesome things about it and my mate got excellent success with it.
Did it last a good while?
Thank you. Exactly what I needed. Six 8-volts for thirty minutes each. Now I understand why my sensing circuit on the charger wouldn’t allow the charge.
What amperage did you charge with? 2a? 10a?
@@johnnywoods227kind of annoying no one ever says that answer
@@philipchesleyiii Going to depend on how low they are, I've brought some 8v banks back that were extremely low charging each one individually on a 6v 10 amp charger for 24 hours. Then putting them in 2 seperate banks of 3 in series, 24v per bank, and charging each bank with a 24v 15 amp charger that has a good lead acid charging profile. If they are starting out at 5.5 volts or higher per battery you can skip the 6 volt charge and just use a 24v charger.
@@Reloadeez I just did them in sets of 2. I charged the first set for an hour and 45 minutes, at 10 amps. Then charged the other two sets for 45 minutes each at 10 amps. I also had to refill the batteries cuz they were kind of low. Worked out.
They were all still connected, I just moved the cables from post to post.
Thanks! I'll give it a shot!
I will have to try this soon, as we have had 6 years of service with our golf cart here in the Phoenix area using the same set of batteries. Nobody believes we've gotten six seasons out of them, but somehow we have. If our batteries stop working when the heat comes back on in May/June, I will try your method for sure. My only complaint about the video has nothing to do with the information given, just the overly loud background music that is absolutely not necessary. Other than that brilliant, well done!
Worked beautifully. Thank you so much!!!
Thanks for watching and don't forget to subscribe.
here's a few ideas for getting a good result
do not attempt to do this until you know what you are doing - the acid can burn your skin
Test the voltage first - there may be a kaput cell which would waste your time.
Check the battery fluid.
attempt to fully charge the battery.
(I learned about these and more from Jons mender guide site )
Thank you for the video
Many thanks..You are awesome😎👍
When you revive old batteries in a battery bank such as with a desulfator, how much time does that typically buy you before you have to do it again? Thanks.
What charger did you use in the video?
I brought back a bank of 8v club car batteries that I thought had zero chance of coming back from the dead doing something similar. They had been sitting for 3 years, had less than 1v per battery on the multimeter, and extremely low electrolyte levels. I added water to around the 60 percent full level and put each one individually on a 6v charger overnight, took 6 days. I then added water to around 75 percent level, and put 2 separate banks of 3 in series on a 24v smart charger with a good internal lead acid charging profile overnight. Topped off the water and did a 24v desulfation mode overnight for each bank. 48V bank read 51 volts on meter when done and each battery was within 0.10v of each other. Have been running on the bank for 2 years with no issues.
Thank you good info
I just acquired a 2001 ezgo. It’s has been in water. Batteries are old. What would be the 1st thing you would do or check
if i have two chargers, can i charge two sets of batteries at a time? to save time?
Can I use this on closed system batteries
Can you use two 8v chargers at once??
Shsss don't tell anyone I've been making a fortune bringing batteries back to life.
Can I have head lights, turn signals and horn with weak or dead batteries
THANK YOU!
Not certain about the points made but ,if anyone else needs to find out about how to recondition batteries try Jons Mender Guide (Have a quick look on google cant remember the place now ) ? Ive heard some extraordinary things about it and my buddy got amazing results with it.
So there is no need to disconnect the other batteries while you charge the 2?
Yup, no need. The other batteries aren't being affected because they're not hooked up to the two being charged.
I have a 48v golf car with 6 Trojon battery. My problem was I only have 40v across from number 1 to 6 after 36 hr of charging . All battery measure 8v except for number 5 only produced 6.66v.
Question:
is my number 5 battery defective and need to replace or can revive it with a 8 v trickle charge?
Also, when I initiate the charger it starts with 12 Amp now 36 hr later it show 0 Amp. How is that happen? Is my charger ok?
I am new to golf car rodeo, any help would appreciate.
I think your chargers meter type reads hi amp when batt r fully drained, and will head to zero as it nears fully charged. I’m no pro tho...
Can you recommend a cheap 12v charger? Since it doesn’t happened yet and just want to have it handy, I don’t want to spend a lot for a charger.
The latest and greatest charger on the market right now is the MODZ MAX charger. It's weather proof and does a great job of maintaining a golf cars battery pack.
DIY Golf Cart thanks for the reply. I’m interested more on the battery charger to use to revive the batteries when it hasn’t been used for awhile. Is there a brand, type of charger that I should buy?
@@Ernie831 No such animal.
How many amps is your 12v charger?
Most likely 1.5-2
I have six six volt batteries and they're all completely dead. I connected the two batteries as you suggested in your video with a 12-volt charger and I still get a zero reading on my charger. If there's no voltage in the batteries how can I make my 12-volt charger connected to the two batteries operate properly
It sounds like you may have dead cells, don’t take my word for it and do more research ofc but it sounds like you make need new batteries
I think The meter on the charger measures amp rate while charging, when hits zero its charged. Check each batt with a multi meter. I think any batt under 6.50 V is bad or getting close
I have a 1984 36v cart and debating on removing on of the 6v and adding a 12v deep cycle making it 42 volt. I have one bad battery and a new 12v I’m not using. Can I do this or do I need to remove two of the 6v and add the 12v to keep it 36v. It struggles with hills as it currently set up so I was wanting to use the new 12v I have that’s not being used to see if I can get more pep. Any advice?
I know this is not what you're going to want to hear but, No that will not work for long. Something will burn up. If the cart is equipped with a controller, you can upgrade the entire electrical system to 48 volts and alleviate all you climbing issue or trade it in on a 48 volt golf cart. You will never be happy doing any climbing with 36 volts.
Thank you for the information. I don’t know if it has a controller or not. I know nothing about golf carts. This is my first one
It’s pretty old and I don’t see anything that looks like a controller for the images I googled. It’s a old cart before electronics so to speak. It’s a pretty simple cart. Old 3 wheeled cart but good condition still for being 35 years old. Lol
@@patrickhailey5812 Follow the wires from the solenoid. One of the wires will be coming from a battery positive and the other will either be going to a coil spring or to a box (controller).
What if I don't have a battery charger to spend 3hrs putting enough amp in battery how can I get it started?
Push your golf cart next to a car with a good battery. Connect jumper cables from the car battery to the golf cart batteries (make sure you connect to the battery ends that are not connected to other batteries the cables usually run towards the rear of the cart and positive and negative are on the correct posts) then turn on your golf cart charger it should now turn on then disconnect the jumper cables and continue to charge your cart as normal.
For 8 volt batteries do you have to take off the connectors?
No, do not disconnect anything other than flipping the switch to TOW.
@@diygolfcart Thank you! I just wanted to say that I have gone through so many videos and found this one and I have so far charged 5 batteries and can finally almost use my golfcart thank you so much!
@@metro9203 Fantastic! Glad to have helped!!
DIY Golf Cart I’ve tried charging one battery at a time for 30 min. Then I plugged the golf cart charger it blinked like it was charging then it stopped and went blank again
@@rustylozanolpc4227 What is the voltage at the charger receptacle on the car? We need to see what the charger is seeing when it's plugged in.
You said batteries are filled, with what? more detail please
Distilled water
Batteries are filled with H2S04 (sulfuric acid), but you top-up batteries using distilled water and only distilled water, not "pure mountain water" or any such contaminated water.
My 12 volt charger has 3 settings... 50 amp, 10 amp, ad 2 amp... Which one do I select for my 36 volt golf cart with Six (6 volt) batteries that are dead... my battery charger for the golf cart will not come on and charge my golf cart.
I have the same problem and looking for a response
Charge two batteries at a time as shown in this video. Start with 2amps, then go to 10amps as the batteries pick up a charge after about 2 to 3 hours or longer. By that time, your batteries should be charged enough so that your cart charger kicks in. If not, you may have dead cells in some or all of your batteries, which means you might want to recondition them as explained in many CZcams videos by using a method you prefer, usually by removing the acid in all the batteries and replacing the acid with acid or similar material bought at an auto parts store. WEAR PROTECTIVE GEAR or you might get seriously hurt.

Save your old battery chargers that charge dead batterys! The new fangled chargers Won’t go figure!
Many smart chargers need to sense a voltage so that they know they are hooked to a battery and then they start the charging cycle. If you have a battery that has a voltage so low that the charger can't detect it, first off that's very bad for the battery and will shorten its life. But past that, if you want to try and squeeze some more life out it, you need a dumb charger to charge it up enough so that the smart charger can tell there's a battery there. Kind of goofy but that's what you do. When you use a dumb charger be careful not to overcharge your battery. With smart chargers you don't have to worry about that.
my golf car is a 48v and batters only have 0.1 to 0.4 volts in them and the car charger won't charge the battery.
Dead cells = Needs new batteries.
@@diygolfcart thank you
My 6 batteries are linked together but the last two are connected to what I think is the charger. How can I determine which one to connect the the positive and negative terminals using the charger?
Connect your batteries in Series. Number your batteries 1 to 6, going from 1 to 2 and 2 to 3, etc. Always connect the positive terminal to the positive of #1 and the negative terminal to the negative to #6, which will provide a charge throughout the entire series of six batteries.
😮
Do I need to fill batts with distilled water, or does Blinker Fluid work just as well?
only use organic blinker fluid.
1 hr lol if the voltage is low eg 1 or 2 volts, to charge each set takes 10+ hrs with 4 amp, so to get the 6x8v or 8x6v batteries up above 37v as needed this can take a few days. (48v)
8x6v unless you make up a wiring set to charge 2x6 with a car = 12v then 6x leads to jump the other 3 sets, with each set only in pairs of 2 then you could charge them within an hr for the controller to take over (+37v)
Why don’t they make a golf cart charger that recognizes low voltage or have reconditioning capability?
I totally agree, I wish someday some individual or manufacturer come up with this new kind of charger.
I think because of govt regulations. Don't want you to be able to use the charger plugged in the and touch the prongs to someone skin and send electricity through them. Safety.
As an electrical engineer I am curious as to how a relay can sense a voltage?
as an electrical engineer you should know there is such thing as a voltage sensing relay. I think that is what he's referring to. Not that its relevant to anything in the video
@@brockmunn7858 you are thinking of a semiconductor or other solid state voltage sensing circuit controlling a standard electromechanical switch (relay)
I’ve got 8 six volt batteries
Go to settings playback speed at the least 1.25, if not 1.5. Thank me later.
hahah!
