Thank you for providing the meter and charger for this video test/review.

That was a good test bro. I had my fingers crossed that that charger could do something to bring a little bit of life back to it. I was watching the numbers when you started and when you ended. And you're absolutely right, it plateaued. Great video though so now we know.
Final thoughts :)
I think you'll agree with me that doing the "Epsom Salt" treatment is over the top to bring an old battery back to life. I have better things to do :)
Yo, Tony, Thanks man. The charger definitely charges good. The repair mode worked better on this test than it did the last test. I am keeping my eye out for a battery that is having trouble but only a year or two old to test repair mode on next. The outcome was still good because I was able to start my mower. Thank you for the charger and battery checker meter. When used together it gave a good overview of what was happening.
I sure used to think that way. I am starting to have troubles with that though because of the new battery cost. I am not sure why it costs so much for a new battery now. I wonder how much it would cost to do the dump, clean,and refill. Would it be worth the time and effort on top of the cost? Would it bring the battery back up where it would last a few years or is it a short term thing? Let me know what you think Tony.
Correction to statement at 1:40: For internal resistance, the lower-case "m" before ohms means milliohms (thousandths of an ohm) rather than megohms (or megaohms, i.e., millions of ohms), abbreviated as Mohms with an upper-case M.
The following is taken from a post at Quora by Mr. Prasun Biswas. [Begin quote]
In a lead-acid [LA] battery, the lower the battery internal resistance [IR], the more the battery in good condition.
To be exact, for a 12V LA battery:
If IR>30 milliohm, battery is in very bad condition. Probably unusable.
If IR is between 10 to 30 milliohm, still poor condition but may be usable or revivable.
If IR is between 5 to 10 milliohm, it is in good condition.
If IR is less than 5 milliohm, it is in very good condition.
[End quote]
Can anyone confirm these internal resistance ranges from a published source? I assume they apply to a car battery. What about a truck battery? Motorcycle battery? UPS battery?
I suggest waiting several hours after reconditioning a battery before checking its voltage. From my experience, voltages above about 12.6 V only exist for a while after charging and do not represent the steady charged value. The voltage after several hours tends to be a multiple of roughly 2 V because a 12 V battery consists of six roughly 2 V cells. Thus, if your battery reads about 8 V, that means that four cells are working and two are not. The repair mode in this FOXSUR battery recharger reconditioner attempts to desulfate the lead plates in a battery so that all the cells can function.
Greg, after a year and a half, is the battery still working?
Hey Jon, Thank you for watching and writing in. Thank you for the Milli vs Mega Ohms correction and explanation. The battery worked all season without issue. After letting it sit for the winter it was dead again this spring. Guess what I did? Yup, this same repair and charge. Well I am happy to say that it worked another season. Getting ready to put it up for winter again. After reading your message I plan to make a new video this coming spring. I hope you will watch and comment when you see it.
@@GreggFesto I suggest Googling:
How to store battery during winter
Key points include taking the battery inside if needed to avoid freezing and charging the battery monthly (beginning at the end of the season) so you won't have to do a "repair" charge next spring. Best wishes!
Given that a brand new flooded lead acid battery presents less than 1mOhm per cell of internal resistance (that is, about 5mOhm as a total, for a six cell or else a 12V battery), the ranges' reference here above seem to be right. As a rule of thumb, a battery needs to be replaced when its initially confirmed internal resistance is doubled. So, if at the time of buying it, its IR was, say, 7mOhms and now we measure 14mOhms, this shows us that the battery has reached the end of its life. The Sealed Lead Acid batteries present higher internal resistances than the flooded ones and finally the common 7Ah/12V UPS batteries present about 25mOhm of IR when they are brand new...
Drain it down to 11V and do the "repair" mode at least 3-5 times. The plates need to desulfate.
I agree.
Good video and test. I didn't notice if you checked the electrolyte level first, you should also run the CCA test after the battery sits for at least 2 hours. Do you know if your battery charger pulses are 16 volt power spikes like a Noco Genius 5 and 10 charger or CTEK charger uses? I have a Pulsetech PowerPulse passive battery desulfator on my 2001 BMW battery as preventative maintenance as Pulsetech claims that there patented frequency they use can extend battery life up to three times. I also used my PowerPulse on my other BMW battery that I let sit disconnected for a year, and it was at 11.2 volts, I tried charging it with my friends Exide 6 amp automatic charger for 14 hours and battery voltage was at 13.1 volts, yet it would not start my other car. I put the PowerPulse on it along with a 1 amp Schumacher manual battery charger for 72 hours, and left the desulfator on it for a week and it started my car right up. My point is desulfation can take up to 30 days depending on how sulfated your battery is.
Thanks for watching and commenting. I did not check the electrolyte level and do not know the pulse voltage. I just tried it out as-is to see what happened. Next bad battery I get in may get more cycles.
I have to wonder if a battery would last longer running repair every 2 months. Or every six months. I have a small cycle that kills a battery every year.
I think that running periodic repair will extend life but the best value for money is a trickle charger. Have you checked into those?
@@GreggFesto Yeah, am currently running a battery tender 24/7. Now, I unplug 24 hours before I ride. Nothing like a fresh charged battery starting my bike. Only to leave me stranded later in the day.
I have read the cheaper battery tenders from places like harbor freight are sometimes not very good and can cause charge issues. What kind are you using? Have you checked your bike to make sure it is charging the battery while you are riding?
@@GreggFesto Yes, have a volt meter for SAE to USB connector. Constant 14 volt. I use only "Battery Tender" chargers. Have more then one. Use successfully on other vehicles. My dual sport is subject to harsh environments, and gets bounced around a lot. It also is probably the tiniest battery I have. It has proven unsafe to charge minutes before a five hour ride. Better to fail at home, than to fail 10 or more miles from the nearest road.
Hey, I can’t see the battery in your video because I’m visually impaired but did you check the water level in the battery? Also, how is your Mustang project going?
Hey Clay, Hope all is well with you. Yes I did check the level in battery before I put it on charge. All cells were full and even across. I am going to continue to use this battery until it wont do anything else then I may try to restore it by flushing it and putting in new acid. Not quite sure yet. The last thing I did to Mustang was taillights. I did just get some brakes in for it so I will make video on replacing them soon hopefully. Clay I want to say thank you very much for continuing to watch my videos and comment. It is much appreciated. Did you have any time to check out Blind Fury TV channel to see how Stephen is doing these days? I think he has found his fit with the UA-cam channel.
