You saved me $500 my man! Both of my 12.0 batteries were dead, all banks were around 3-3.8v on both of them, charged each bank back up to full, slapped it on the charger to "reset" it and now i have full 4 bars of charge again!
Just a heads up: when you take the casing off, there’s +/- all along the bottom of the banks on the plastic. Clearly indicated. My question to you is: with the banks that are connected together with the metal. How do you know where to put your wires. Wouldn’t it short out the bank that shares the same weld plate thing? That’s a detail that I really would have liked you included. Cheers.
@@fixer2uI realize that. What I meant was, are the vertical banks insulated from each other somehow? Because from what I gather, when you charged the second bank, you slipped your positive/negative leads in the same way. Adjacent the second vertical battery bank. My question was: that whole metal façade… how is it not pushing voltage to the previous bank as it seems it’s all on the same plate. (Except for the 5th one of course) Maybe a dumb question. Sorry. I’m about to do one of mine based on your tutorial.
Just take 2 razor blades and 2 batteries one good battery and the one that doesn’t work, go positive to positive and negative to negative This will charge up the dead cell (without having to take anything apart or having to buy anything, long as you have more than one charger) If you want to be more safe and not risk ruining the other battery, (yet this has never happened to me) but you could also do it with wires, then on the positive side add a fuse to insure you don’t crap out 2 batteries.. However I just risk it an haven’t had an issue and have fixed all my chargers!!💯
Also forgot to add I let the connected batteries sit together for 30 minutes every time… an then I throw the non-working battery on the charger and im back in business battery good as new! I think this could potentially blow up, I’m no electrician, so don’t do it in the kitchen like me lol go outside and stand back for the 30 mins to be safe.. however I don’t think it’s possible for them to blow up do to being the same voltage… It definitely works though saved me tons of money, I’m always stoked when I see someone go to throw away a “non-working battery” I always say “I’ll take it, I scape at the end of every year and they give a tiny bit 4 batteries (not really true lol) I’m tryin to save up some batteries!! hahah jk I always will just help most people an teach umm not to throw them out an I always risk my battery to save theirs lol (too nice) haha Now time to buy the one part to fix my sawzall, really don’t want to fix it though, wanna use it as an excuse to get the hacksaw for my wife… “my sawzall is completely unfixable, time to get the one that works better for plumbing” hahah I mean it’s not like you can ever have too many tools 🤷♂️
I have a question, if I do not have a battery charger could I accomplish the same thing if I drain each bank down to balance out the good and bad banks, then put it back on the m18 charger?
FYI - don't get greedy and try to charge two low banks at the same time. My Opus charger briefly flashed 4400ma as the charge rate as the banks tried to equalize through the charger when I hooked up the second set of leads. Yeah, those banks are still in series so can't hook up to two at once. Charger survived, tougher than it looks. Thanks Fixer, don't remember if you mentioned that, watched this long ago and just skimmed again now.
I have 2 M18 12 batteries that only show 2 bars and then show fully charged. I would love to try this but to be honest, electricity and thought of blowing these up scares the heck out of me. The link provided doesn't appear to be for sale but they have the C3400 which appears to be same but next model up. Would love to fix these.
Did u try a sea foam type product first to see if that helped and how did u prime the injectors after cutting off the fuel supply, thanks for ur advice and always enjoy ur videos, very helpful for my own R tractor.
I did not try seafoam, but that is not a bad idea! I just changed the oil though so not really looking forward to doing it again! To prime, you go to the fuel filters and there are priming plugs above each plus on in between. You take out the left plug until you get a steady stream of fuel. Then do the right plug, then do the center. At that point you should be primed. Have a full tank of fuel in there also as the extra head pressure helps.
Just fixed an XC8.0 with a $30 "MiBOXER 18650" charger I had lying around from flashlight games. Definitely important that it's a current-limiting charger, but at 200mA nothing even got warm. Thanks for the video!
@@fixer2u I have other batteries blinking 1 bar and I was experimenting and fried my charger. Have you tried to charge cells with another fully charged battery?
Thanks for this vid! I bought the same charger to revive two 8.0s. It brought one of them back, but on the other one, all banks read 4.19v but only 3 of the leds light up.
@fixer2u I really like the concept. I am a cabinet builder and finisher. I've been with the same builder for over 30 years. When I was first starting out in the business, I was friends with an old finish carpenter who had built his own cabin out in the woods. He cut trees off of the property and used them for the wood. He told me that he used diesel fuel mixed with gear lube to preserve everything... I can't imagine the smell it made. I never forgot that story.
@@robdittes5228 Oh wow that is really cool! Yeah there was definitely a smell to this trailer for a couple of weeks, but now I do not smell it at all. That is brave using that on a cabin especially if you have a wood stove!
Any chance you may have the specs or drawing for the crankshaft? I contacted the company you sent yours to and they requested a drawing for specs…….I’m rebuilding the pony on my Model R as well…. Keep up the great work with your videos!
@@Xplorer228 yeah true. I mean you can still get in there with a wirewheel or wire brush and the exhaust manifold paint will work in there too. Its rated for 2000F.
@@fixer2u well I wanted to say I opened a new charger and two of the batteries charged a few months ago to three bars and worked fine but my girl plugged that charger in and left it, And yesterday it drained one of the batteries and now I used it to try to charge the other and it's not working I tried charging other things on the charger but it shines green on the 12 volt side with nothing on it and it just shines green on the 18 v side whenever something is plugged in so I think my charger is trash now and for some reason my rapid charger isn't even lighting up when I plug it in but once I get it to three bars again I'mma use your method to see if I can save the batteries but is there a local store I can buy the battery charger at if not is yours the 3100 or the 3400? Also do you think I need to buy new chargers or is it fixable thing for the chargers as well, and does this method work 100 percent of the time?
@@philantemalone9675 I cant help you with your chargers. I have not had anything go wrong with mine. I also cannot help you with your local store question. I personally have not seen a charger like this in a local store. For me this has worked 100% of the time with my batteries.
@@fixer2u nice well even the one awnser was a huge help and greatly appreciated but I was wondering tho which model battery charger it is because and if it doesn't matter between the models I'd but the cheaper there was two different from that brand on Amazon but thank you very much this definitely is a huge help I'm such a non wasteful person and I can't see myself wasting hundreds of dollars on batteries but why does this happen just from non use I did have those batteries sitting for a few years?
Battery Issue. The Fix is Place a Jumper from bad battery to a good charged battery. Pos + to Pos + and Neg - to Neg- terminals wait for about 15 minuets for battery to equalize. problem solved. both batteries are ready for work or charge to full
I did a brake job this winter and my tire was so seized on I had to actually loosen the lugs, then go for a drive and do a couple hard stops to loose the wheel, it worked, but damn that thing almost killed me before I thought of that, it would not budge and I even had friends come try. Harbor Freight has a cheap tire changer that has a bead breaker built in, very good tool especially with duckbill mod.
Yeah that truck has been stuck worse for sure I have had a much harder time in the past. I have seen that tite changer but I might only use it once every couple of years....
This Man deserves a new Fluke, or at the very least, a new Klein MM. 😊 I am going to try this on a couple of my M18 XC batteries that give the ‘Christmas lights’ when placed on the charger, as well as a couple of my M18 8.0 HO ( expensive ) batteries with the full charge showing only 3 bars. I have a NiteCore charger that will charge LiIon batteries up to 21700 in size, so will try this. I have scrap dowels lying about, so will give it a go. I’m thinking the NiteCore charger will suffice?? What say You? Much appreciated! 👍
I had a bank (M18 12AH) @ 3.67 and it took almost 12 hours to get just below 4.2... Is that normal, in the video you mentioned an hour? Great video by the way, thank you.
Thanks for the comments, what did you have the amps set at on the charger? Mine has taken that long. Since I have published this video, I have had to do this on other batteries.
google must be listening lol, just offered to help fix a family friends kitchenaid that was leaking oil yesterday and now your brand spanking new video gets recommended to me today. Thanks for the upload!
Thank's for the video. I will be doing this fix as well since we have the same problem with it leaking. I will be using this as a reference. Once again thanks for the video.
