For those who don't quite understand, what he is saying is that there is a low level cut-out switch at approximately 4-a5 volts. So If the battery sits too long and drains, which it realistically should not if it's plugged into a tool because the tool has a low level switch to stop draining the battery before it reaches this criteria, the battery has a cut-out switch so it cannot charge. So by going into the battery and bypassing the little brain and directly charging the cells up above the brain cut-out threshold, he tricks the brain by bypassing it and giving the cells enough power to get the brain to open the passage for charging again. This works about 70-90% of the time, but if you have a burned out cell you need to revert to another video. Thanks for your great short video!
Making use of the ruclips.net/user/postUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type
After I watched your video yesterday evening, I had two batteries that would not charge I done exactly like you showed it works flawlessly thank you young man, you made it simple and easy to understand thank you
That’s awesome! I appreciate the feed back and thank you for watching 🍻
I would listen to your thing about the batteries but I can't hear you you're too low what's the sense of listening if I can hear you
@@joeyoung2119 I am deaf - I watch RUclips for hours a day, subtitles rock! Try it.
@@joeyoung2119turn your volume up
Reasonably new battery brought back to life. Works perfectly. 10 minutes. Thanks!
It worked. I used the 12v battery on my motor mower, connected to the Ryobi battery with jump leads. Thank you. Very satisfying!
You're the man! I had 3 dead Ryobi 18 volt batteries that I've held on to. After watching your video, I did as instructed. All 3 chargers are blinking green again and charging the batteries! It took me less than 15 minutes to do all 3! Thanks for saving me the money and frustration with Ryobi.
Thanks for watching 🍻
There's a dozen or more of these videos on RUclips, and I was happy I went with this one. Cuts to the chase; doesn't require me to hack my Ryobi charger. $15 trickle charger was worth the investment to get three formerly dead Ryobi lithium batteries in play again.
Thanks for posting.
Thanks for watching 🍻
I sometimes try these RUclips videos to fix things and they very rarely work. However, this time, everything worked perfectly and I know absolutely nothing about electronics! VERY clear instructions and showed me exactly what to do. I have no idea how to actually use a trickle charger or a multimeter but with this video I was able to fix my Ryobi 18 Volt battery and, more importantly, impress my wife with the blinking green light!!! Thanks so much for a great tutorial. I wonder if that process works on other similar batteries too. Keep up the good work. You are the MAN!
Wow, this very nice! thank you for watching, I really appreciate it. Cheers!
Great fix! I had a Ryobi 18V 3ah that just went out and you saved me $67! Works great again and I now know to keep a charge on them too. Easy once I had an T10 extention torx bit. Thanks for posting.
Glad I could help
Wow, worked great. Hardest part was finding the right torx bit.
Had a Ryobi 18v battery that died and wouldn't charge so I marked it bad and had planned on throwing it away. Before I got around to throwing it away a much newer battery did the same thing. I was thinking I would have to buy a couple of new batteries. I decided to do a search to see if anyone else had the same issue and I came across this video. Being a retired mechanic, I had everything necessary to try this process and it worked great. Took the batteries apart as shown in the video and used a small 12v charger touching the leads to the batter for only 1 minute. Both batteries are now charging great. Thank you for your video!
Awesome , thanks for watching 🍻
Thanks man.... you helped me fix TWO things with your vids (vacuum), keep sharing your stuff.... from ireland.
Thanks for watching
Worked for my Riobi.. I had left town for a few months, coming back to a dead battery .. (so, not overuse).. A quick boost from a working battery (1 minute connected) , and everything is working again.. Thank you.
Edward Pinsent 💥 nice , thanks for watching and letting us know it worked for you! I really appreciate it! Cheers! 👋
i went and bought the harbor freight charger and it worked like a charm i was really excited thx again
Thank you. I'm off to Harbor Freight to pick up 12v trickle charger. You saved me cash on new Battery.
Nice , it worked for you too,. Thank you cheers
Thanks a ton as I'm a heavy Ryobi user , drills , cordless and corded, saw, sheet metal saw , circular, multi tool and just about everything except the blower lol. But seriously I've got 1 battery exactly like the one you demonstrated on and 8 others ,so I'm just going use that hack and get it right back up. 🙏🎯👍
Very cool! Thanks for watching! I appreciate it!
Thank you young man I appreciate it I've got two of those batteries that died on me and I didn't know what I was going to do, when I seen the Harbor Freight charger come up the light bulb went off in my head an old dog can learn new tricks thank you son
I hope it works out successful for you! Thanks for watching I appreciate it. Cheers 🍻
Look at your battery case to see if it offers pos and neg terminal markings. I was able to charge my battery without removing the casing/cover. Worked like a charm... took less than 30secs of holding the clips on the terminals before I plugged it back in to the ryobi charger and it started charging as usual. Thx for the video!
Thanks for sharing and watching 🍻
Yeah, I've repeatedly put them on and off the charger to "rejuvenate", sometimes 10+ times before they start charging. Used to have them not charge all the time and would use that trick... but learned to not run them down till they're dead when in the tools and none go bad anymore.
I've got two old Ryobi 12 volt batteries that won't charge. I was gonna throw them away, but I will try this trick. Thanks. Cheers from eastern TN
Worked like a charm. THANK YOU!!
I'm so glad I found this video, thanks for pointing me in the right direction 😮😊
Fantastic. I have six (6) P102 batteries that have all went dead. Going to get that charger and bring them back to life. Thanks for saving me much money
Gary Leahy nice , I appreciate it, thanks for watching
I tried this today and it worked perfectly !! Thank you !
That’s awesome, thanks for watching 🍻
This worked like a treat, thanks for the fix
i am a ryobi fan and have 18v plus system batteries for a while and been replacing as they died, i assumed the batteries would no longer hold a charge or take a charge, your video is interesting and i will certainly give it a try, it gets expensive buying new 18v batteries , thank you for the tips
It’s definitely worth trying, but those batteries do fail over time , so do consider that a cell could be bad. Thanks for watching 🍻
Worked for my battery !!! I had a battery that I couldn't "fix" by connecting to the visible terminal connectors... So I opened the battery, as shown in the video, and connected the charger directly to the internal batteries (thereby bypassing the electronics) and now, all is good.
Thanks for watching, I appreciate it 🍻
Great post, worked like a charm. Just think of all the people that ran out and bought new batteries, when all it was was a crappy PCB set up. 👍
I had a Ryobi 18 V battery that sat in my garage for over 18 months that would not take a charge.
The "Fix" was fast...easy & safe.
I used my 12VDC trickle charger ..held the "+" & the "- " cables to the battery posts for slightly over 2 minutes.
I then put the battery into the Ryobi battery charger.
The charger "Testing" cycle ran a little longer than normal then it started the charging cycle !
I did not do any disassembly ...I didn't drill any holes !
That’s awesome, I’m glad it worked out for you! Thanks for watching 🍻
I lost one battery unnecessarily a while ago, so this is definitely worth a try to save another one that ow doesn't charge.
It was a very good video. But I have two questions, 1 why do you have to take the battery apart, I didn't hear you say you needed to take them apart??? My second question is, can thus be done to a regular Ryobi battery, a no Lithium battery??? Again great video
Thanks for the video. I used my car battery charger on the maintenance setting. It worked.
Excellent! Good idea
Thanks that was my next question.
Holy shit bro!!! I just saved a battery thanks to you.
Thumbs UP!!!
Nice 👍🏼 Thanks for watching!
Thank you very much, exactly the same problem, and with your help problem solved My hero
Awesome, dude! Thanks for the tutorial. Got 2 batteries repaired this way, trying on another brand now too. Appreciate ya!
Welcome to the channel, thanks for watching 🍻
Thanks for the tutorial, p190 , revived
Great job dude ! work perfectly for me too. Thanks from France
Brilliant!!! I now have to see if I can get my 2 batteries back serviceable. Thanks for the info. 😉😉👍👍
Great video, saved me from having to go and buy another battery. Thanks!
Awesome thanks for watching
Great for a one time fix. I wouldn't want to do this after it quits the second time. Thankx
Absolutely by that time it’s best to properly discard 🍻
Rather than a trickle charger I simply used another Ryobi 18v battery and connected it with a couple of handheld wires for 30 seconds... bingo, dead battery up to 12v and the charger recognises it instantly. Many thanks :)
Excellent!! Cheers
works like a charm!!!
Works Great! $9.99 From Harbor Freight and 20 min. labor
Best video on how to do this on youtube!
Thanks for watching I appreciate it! Cheers
Nice video and great info.
this is better than most videos on this platform, but the key problem is that you should have a professional charger like the imax b6ac v2 and attempt to charge each individual cell that makes up the pack to its normal voltage. another thing to keep in mind is that although it might charge to full it could have bad cells which could be contributing to poor life. these individual cells would need to be replaced with ones of the same specs in order to prevent damage. as I said in the beginning this is a much better video than most and should work for many people. I would urge caution to inexperienced people who think that applying voltage is going to solve their problems. I have seen many things that are a safety hazard and many videos don't take safety as a priority. just to let you non electronics savvy people know that it's not so much the voltage that can kill you, but it is the amperage that will do it. most current above 100ma could be lethal! take extreme caution. if you don't feel comfortable, leave it to a professional.
I have a 1.5ah Ryobi battery that only charges to 2 bars instead of 4. Does that mean there's a bad cell needing to be replaced? So, the method shown here wouldn't help? Thanks.
Holy Cow!!! My "spare" battery has been dead for 4 years, and i thought i had a bad circuit board.... Now working again, thanks to your tip!!! By the way.... I bought one of those driver bit kits from Home Depot, and i use it alot in my electronics shop. I love it!
Rusty The Raver very cool !
Thanks for the information. I have one that won't charge so I'm going to try it out.
@Edwin Leach 💥 nice, thanks for watching!
Great video. I have four RYOBI "dead" batteries. Your video might just give them a new life. My plan is to use my trickle charger too. It's too bad that RIOBI, and others, don't have a way to prevent this from happening in the first place. But then they won't sell us new batteries thinking ours are trashed. I will be putting this video in my saved video folder.
Thanks for watching I appreciate it 🍻
it's because the bms has no way to determine if the pack just has a dead cell or if one is actually shot, and when they become overly discharged and the individual cells aren't balanced there's always a risk of overheating and fire, that's the real reason why it happens. just take care of you're batteries, keep them out of temperature extremes and keep them charged up but don't over charge them. most people just use their drill once in a while and don't keep their packs charged. hot and cold don't help either.
this got you a new subscriber, great work , nice chapters
this links broke Buy 12v charger here
Thank you for sharing this! It Worked!
Thanks for watching I appreciate it
Perfect tutorial thanks!!
THAT'S AMAZING! Saved me $54.
Sweet , thanks for watching
Great video thank you. Guess what I'll be doing in the morning?
💥 nice, thanks for watching, I think your fixing batteries, haha cheers!
Thank you so much, so any 12v battery maintainer can save the pricey battery. Wow, I will get one motormaster 12v 0.8a battery charger and maintainer to try
mic wang Ian just using it to bring the battery voltage up to a level , that way the on board chip can recognize its there. It doesn’t take much. Cheers
Thank you for the tip.
It works. 👍
Good stuff. Thanks for the info. Now let’s see if I can charge mine.
Thanks for watching
@@ATEMOFFROAD I was going crazy figuring out every possible way to fix the problem. Since I don’t have the package it came in. Long story short. Reads defective. Appreciate the time taken to do this.
You should always clip the positive terminals before ground. Great video though. I’ll try it!
Thanks. Worked on PC18BXL (Porter Cable) that had the same type issue. Wouldn't charge. Have 2 units 3ah and 6ah. T10 opens but need a longer one on the 6ah.
Thanks for sharing and watching 🍻
Do you have to remove the cover or can you charge it thru the open ports
Worked for me. Thanks
Thanks i try this procedure to my old batteries
This procedure is for newer batteries not older. Those cells may actually be bad . Discard battery properly.
Thanks I just watched a video where they drilled holes instead of just removing screws. Facepalm moment. Thanks for the video 👍
Thanks for watching
I've fixed batteries by putting them in my freezer overnight and YES it works.
That’s awesome! thanks for watching
Outstanding video.
Thank you it worked !!
Excellent info, both how-to and what the problem is. I'm curious about their justification for not having at least a 'recovery mode'!
Thanks for watching I appreciate it! I’m curious too . my thoughts are they have a really good warranty on them so you are not tempted to break the seal! Can you imagine how many good batteries would be thrown away with out one in place? This is Very Bad environmental issue!
@@ATEMOFFROAD Right now I have four of these batteries that are "defunct". Oneif them useless than six months old but I cant prove it. I will try your method with great hope! If merely bringing the charge above a minimum threshold is all it takes to "repair" them, without some reasoning why this is dangerous, this looks to me like an artificial battery marketing program.
@@GaryBickford the battery you see in this video was less then six months old ! Now it’s still works like a charm and has not had an issue since! It beats having to manually sweep the porch, the ryobi battery is bad not the blower,Hope all goes well , good luck! Be safe and report back 👍🏼
I will that a try!! Thanks
thank you it worked !
well done!!! one of my Ryobi 18v just went tits up the other day... $70 replacement at Home Depot is just not in the budget right now.. many thanks for this very informative fix-it video...
Thanks for watching 🍻
It works! Thanks for sharing.
Thank you 🍻
Wonderful work, keep up!
Thanks for watching 🍻
Spot on, it works.
Rui Nunes nice , thanks buddy!
Why do you have to take the cover off the battery? Can't you just attach the alligator clips to the terminals on the stem?
Because you're bypassing the circuit board that controls the charging and has been stopping it from charging. He does say that.
The terminals at the top are what already read the charge and the circuit board is stopping it from charging in the first place. Bypassing it allows it to charge directly to a battery
Wow I want to try this!
All my new Ryobi tools use a different battery, in that the charger contacts are on the opposite end (and the bottom of) the normal battery insertion port for the tools. How this might effect overcoming a 'dead' battery scenario is a bridge I will cross when I come to it.
You ROCK 👍🏼👍🏼Great video, great info, great results (totally worked!) = Super Helpful, THX!
Thank you
First video that explains why the batteries will not charge and how to get it working again .
I think that there is a low voltage shut off in the circuit board so that the batterys can only be discharged to a certain precent to protect the batterys , and then if the voltage drops even lower it will not connect to recharge .
I totally agree, thanks for watching
Thankyou for this very helpful vid but the 12v trickle charge didn't work for me though here is an alternative for anyone else stuck with the same issue. I have an 18v 5.0Ah pack that was down to 15v preventing any charge so the 12v would obviously be too low of a kick-start where I found a 19v (3.95A) laptop charger and connected it the same way to the neg and pos for 10mins till it got to about 19.5v then put it back together where I used the original charger to maintain it's nominal value of 20.2v.
Nice 👍🏼 just needed a few More volts to get the charger to recognize the battery 🔋 way to adapter! Thanks for watching
@@ATEMOFFROAD I really envy you all that upload these helpful vids and I should do some of my own but I usually find what I am looking for and emphasis on that in the comments (hence yours) and give my appraisal.
Thanks.
Thanks for this video! How long do you find this works for? I assume when it stops charging, the battery is on its way out. If this give me another year of life, it'd be totally worth it. But if it's something that gets me another month or two, I'd probably just recycle it.
Mine is still working since the video has been published, thanks for watching
@@ATEMOFFROAD Thanks!!
Sweet thank for the help
Thanks for watching
I just tried your solution and it worked! Thanks! But; why take the battery apart? Couldn't the same result be had by simply touching the charger leads to the + and - terminals on the battery?
I had a battery that I couldn't "fix" by connecting to the visible terminal connectors... I opened the battery and connected the charger directly to the internal batteries (bypassing the electronics) and all was good.
No cause you need a quick voltage jump direct to batts, "around" circuit control board.
Using visible terminals wont do that
great info! how about some volume.
Lithium batteries (depending on the actual chemistry) do not like to be totally discharged. To maximize battery life, don't let them discharge to zero. The battery packs have safety circuits that shuts the battery down when the battery discharges to a certain point, but the circuit needs a little power, and battery self-discharge keeps happening in the battery. A total discharged Lithium, similar to lead acid, battery will be permanently damaged. This fix by-passes the charge control and battery monitoring circuits and puts enough power back into the battery to power those circuits to enable charging. Good information, but be very careful to watch the battery pack during this process, because it can start a battery fire (don't leave battery pack connected if you leave the room.) Lithium chemistry is much more finicky to charging, and all those electronics in the battery pack and charger are doing a job. Bottom line is to keep Lithium battery packs charged 70-100% while in storage, and throw them on a charger every couple of months to keep them healthy.
Very good information sir , thanks for watching and sharing! Cheers
Good video. Very clear procedures.
Scientifically explained....
So the simple answer is they cannot be revived asinine your video.. Right?
Temper temper no need to be rude
Great how-to video. Thanks!
drumbeatclub 💥 nice , I appreciate it, cheers
I have seen this technique using 24VDC charger and yours using 12VDC charger. Both seem to work. Knowing little about LiOn batteries except all sorts of warnings about using only designated chargers can you explain why either 12 or 24 volt power supplies work without a problem for "shocking" this battery pack back to around 12 volts where it can make the Ryobi charger start charging again?
We are simply using the 12vdc to bring cells that have discharged back up to a threshold voltage that the chip on top can sense to then take over and charge battery! Cheers
my makita battery pack charged 1 times and with 24hrs the battery had drained. So i took apart the battery pack and recharged all the 18650 individually in a separate charger, 4 out of the 10 were .5v and most where 1.4v, so even the ones with .5v were able to charge up to 4.1v now im letting them sit for 48hrs to see how much they drop and hold a charge.
I dont have a trickle charger. Can i use my power bank that can jump start a car?
I think when you disassemble a battery you should use a battery screw driver ?
Buy B6 Imax universal charger to safely charge any lithium (and other types) battery without damaging it.
Just 2 days ago I "recovered" a dead 24V Li Ion hand chainsaw battery BY freezing it for 14 hour, thawing it for 7 hours and then Taa Daa RECHARGING IT!! (As per information I found on the Inet.) . After thaw, the charger showed GREEN - with a periodic FLICKER OF - RED. Hang on sloopy!! Initially I was disappointed thinking the Inet info was bad [tho told about the red flicker]). I waited about 45 minutes and the LED turned solid RED and began charging 4 hours later solid GREEN charged. It now once again powers my saw
As Johnny 5 would say NO DISASSEMBLE! No Multimeter, no strange screwdriver tips, etc!!! TRY this route first. IF IT DONT WORK then do the disassemble route.
Just asking was thinking about trying this but have no experience
Great video. I'm having trouble finding a small trickle charger like yours in the UK. Can anyone out there help?
You can use a regular 12v battery or a power supply. The one I used is just a 12v trickle charger 🍻
I haven’t read all the comments, but do you think you can do it without taking the battery apart? Meaning hook the trickle charger to the positive and negative leads that would take the charge from the ryobi charger? I wasn’t sure if it was the BMS or the charger causing the issue.
I suspected it was the board and not the charger but some say it has worked the way you mentioned it! Also keep in mind you could have a bad cell , this is another reason why you would want to take it apart! Thanks for watching 🍻
excellent video, but i am confused as to the charger that you used. if you could explain further or point me in the direction as to where to find one.... thanks....Semper Fi.
It’s just a small 12vdc trickle charger, this one I picked up at harbor freight for 8 bucks. Thanks for watching 🍻
I put mine in the freezer overnight and they almost always start to charge when plugged in.
The other thing for really stubborn Li batteries is to take a 9 volt rectangular battery and 2 alligator clips and connect + to Ryobi + and - to -...about 15 seconds later the 9v battery gives the Li battery enough to appear alive and then you can charge. You don't have to disassemble the Ryobi to do either.
I am interested in your Battery Charger, (the automotive one), but the Amazon link is not working. Can you provide more info on that charger? Thanks!
This one is very similar amzn.to/42T0sUU 🍻
