- Ever wonder how to know if your deep cycle batteries are good before you replace them?
This video will help you follow a step by step to testing your standard, flooded type deep cycle batteries. Note - Gel & AGM type batteries are sealed and can be tested with voltage and amps but the electrolyte is not designed to be accessible so never remove their caps.
Tools needed for the VACE formula:
A. Standard voltmeter - amzn.to/3gEoMnm
B. EZ Red (preferred) Battery hydrometer - offered on Amazon amzn.to/3BmayzK
C. Battery Load Tester - also offered on Amazon amzn.to/3mI5v8I
D. Safety glasses
Open Circuit Voltage OCV
2.1 Volts Per Cell (VPC) = 100% Charged
1.75 Volts Per Cell (VPC) = 0% Charged
Specific Gravity S.G.
1.265 or Greater = 100% Charged
1.225 - 1.230 = 75% Charged
1.185 - 1.190 = 50% Charged
1.140 - 1.175 = 25% Charged
1.125 or less = Discharged
Always use hydrometer at end of charge cycle to check % charged

Thanks great videos keep up the great work!
You were awesome ..I have looked for answers to questions . And I have to say I have never been so impressed. Thank you for helping stupid people like me that just want more knowledge . I can’t thank you enough . You’re very informative !
finally a very smart man, i so agree with you, we work with current, voltage is exciting electrons, a great load test yes sir, a loose wire causes sparking, will cause pits on the terminals, i so agree with yo sir
Dude that was awesome info
Big TY
Thx for the info
Am a former electronic instructor and I easily give this training video 5 stars! *****

They love calling on a Sunday!
thanks!
Thanks for the video I learned alot.
How did you convert AH to CCA on deep cycle batteries? Only car batteries indicate the CCA.
That battery is huge!
Do you have a recommended load tester for 8v batteries? Or can I just use 6/12v tester?
How long after charging the battery should I wait before testing the electrolytes?
I have a question more than a comment I have a 1000 amp load tester that tests 6v, 12v, and 24v batteries can I use this for 8v golf cart batteries?
Right now I am using the 12v scale but not sure what kind of voltage drop I should expect
Nice clear explanation on checking out the battery. Thanks.
Should the Crown 6V battery in the video be given an equalization charge since there is a noticeable difference in the specific gravity of the cells?
Yes, perform eq on day one and then approx every 45 days thereafter.
Thanks.
Hello Jeff, My name is Pat good to meat you. I need to ask so questions, I am building a small solar system and don't know witch way to go and cost is a big factor. Do I go 6 or 12 volt, flooded lead or AGM. I will probable going between 300 & 400 watts, and using solar and alternator charging while driving. Can you offer some advise to the battery end . I live in Hemet Ca. and can make arrangements to come and pick them up. I hate to bother you but don't which way to go. Thank you for your time and trouble, Pat
Hydrometer question? What reading is acceptable and what is problematic? Thanks
Jeff do you have any tips for keeping my 48v (8v x 6) Golf cart batteries charged that sits unused for long periods of time?
Certain brands of 48 volt golf cart Chargers have a mode that will keep the batteries fully charged. First one that comes to mind is a brand called Quick Charge. Battery minder also makes a 48 volt tender
I’ve got six 8 V batteries in my golf cart. When I test them under load they’re showing between 6.6 and 6.7 V apiece. They’re about six years old. Is that an acceptable working number?
So the end of the video had me do the test. I am getting quite a bit of voltage from just touching the grease or whatever the thin layer of liquid is on the top of each battery. What is the best way to clean these things? Thank you im hoping that may be what is draining my batteries so quickly.
clean off excess conductive grease with a rag and make sure top of battery is also clean
Hi Jeff, I have an off grid home and am using Crown CR430 batteries. Will the Battery load tester work with that much amperage, if not what do model do you recommend?
The load test is a snapshot to batteries health. Typically you would fully charge L16, load test with 200-300 amps and observe voltage not dropping below 2 volts. Back up results with battery hydrometer
Interesting info regarding the 650A CCA rating for GC2 batteries. That's helpful, thank you. Any idea why GC2's do not have a CA or CCA rating on the label, or on the factory spec sheets?
What I'm trying to determine is -- similar to the max. C/5 charge rate -- if there is a max *discharge* rate. We currently have 12 each CR-225 batteries for our whole-house UPS. They've lasted about 10 years, but it's time to replace them. I'm wondering if we can get away with 8 batteries. We are using 2 Trace DR2424 inverters. They pull 140A each at full load, but the load is generally just a couple hundred watts. The heaviest load is our well pump -- either 1/2 or 3/4 hp (I can't recall).
Good question about max discharge rate, because if allowing batteries to heat up is a problem during charging or discharge, then certainly an excessive load could create excessive heat - but I wonder if batteries have that indicated as a rating in their specifications. If not, why. Paper shredders indicate how many pages can be shredded simultaneously, and they are also rated for minutes to avoid overheating and damage. It would make sense to have batteries rated in a similar way.
I have a 2002 club car 36v battery is reading 8.6 on the volt meter. Why?
Quick question...I did a complete clean of my car battery and tipped all the electrolyte out and cleaned inside of battery with water and baking soda...now I come to realise I need to refill the battery with mixture of sulphuric acid and distilled water...can I use the hydrometer to test the mixture ratio before putting it in the battery...so for example mix some acid with water and test with hydrometer untill it reads in the green the 1200 range...and when it does it's the right ratio? And then fill the battery up with that ?
Good idea I've never tried that. Or find another battery that's toast and use the acid from it
REMEMBER....Always add acid to water and NEVER water to acid, it can blow up in your face(not a fire explosion, but it can hurt you).
But I add distilled water to acid nearly every month when level gets low?
i use 6-6volt duracell batteries in my cart. they are 2 years old this month. i charge them between uses and have added very little water only because it didn't need any added. why did my cart run fine for 36 holes for almost 18 months and the last 6 months decrease slowly whereas i barely make 18 holes...if i'm lucky. purchased them at Sam's Club. any suggestions. thank you
the best diagnosis tool for a flooded six full battery would be to purchase a battery hydrometer and check your cell specific gravity look for equal readings across all the cells
Ho jeff writing from puerto rico...how do you check amps on a 6v 420ah bateery carbon lead
this would require a discharge test that is not diy friendly, However an inexpensive discharge item can be purchased on amazon for about $50> Will Prowse has a video specifically on discharge test on batteries that is relevant to your need
How can I ask a question 🤔
My hydrometer i just bought shows almost no movement filled with the electrolyte .but the load tester showed good battery, just got these batteries used. All fluid is to top of fill holes
Charging your batteries at that level of fluid can cause it to overflow. The plates swell. There are indicators at the bottom sleeve inside to stop. The fluid rises to the top.

DO Golf Carts have a charging system?
most carts come with an external or portable charger designed for the carts voltage. some carts come with an onboard charger located in or near the battery compartment
i have 2 6volt batterys, they read 6.1 volts. each, but i put them in my small camper and they die over night with some mild use............ i looked inside and dont see any liquid, the plates are moist
Top it off with distilled water like he said (quarter inch above the plates is considered full). It will bring them back to life and be able to get a good charge.
Can you bring batteries back to life my battery went dead over the winter and they wouldn't really old but they don't take charge is there a video how to bring them back Cajun land Church Point Louisiana
Bloke cheerio..pip pip bucko
That's a 12V load tester bud; and since golf cart batteries are not cold cranking AMPs like auto or marine batteries, the test is bogus. Look at needle in video, it is in the red zone (replace) to begin with. This test can actually damage deep cycle golf cart batteries
People are listening to this "expert" poor soles
You telling people to load test a deep cycle battery which is Wrong, unless you doing a proper discharge test over a day or longer you are giving people wrong advice. Delete your video
