Thank you! I fell asleep 3 times watching you take the screws out!
@@garysampson5258I'm for the
Hey , that’s so easy a caveman could do it 😂 Thanks Brent for the time & effort! I fixed my old one & a new one that came like that ! No need to return it to Home Depot
@@garysampson5258 Took way too long for those of us who have a little bit of knowledge about tools and batteries and how to disassemle / reassemble things. I thought him 'looking' for the correct bit was somewhat disingenuous since he had clearly claimed he already had worked on restoring that battery. But, I endured to the end .. and watched the entire video. Was a learning experience when tinkering 'inside' the open battery.
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!
I love your name
Upgraded from an older 18v kit. th-cam.com/users/postUgkxW1vOBRCMrgTCDEijzpVzDWsgI-Jm2iQv I independently chose the drill and impact tool, before I came across the kit.I like the 3 speed impact gun. It seems more powerful than my older one, and it can be set to be really gentle. The drill is more appropriately sized for my use. I used to have a hammer drill, but I did not like that it was so big and it was not a great hammer drill. I rather have a smaller drill like this, and then get a corded hammer drill for the odd case I need that.
Thank you for making this step by step video!!! I had two of theses batteries in my battery recycle collection waiting to be dropped off and two replacement batteries in my shopping cart. I watched your video and followed your instructions and both batteries are now fully functional!! This saved me and many other folks a lot of money! Thank you!!!
Just used your video to revive a battery pack that has been dead for two years. Thanks
glad this helped you out!
Just a friendly hint. Shorten this 16 minutes to 4 or 5.
Good advice for almost everybody on You Tube. Most videos are way TOO LONG!
No shit. He talks to much. I’m glad you can jump ahead.
@@rickbailey1053 th-cam.com/video/2J1RhAK31KY/w-d-xo.html
I concur.
@John Darke just a friendly hint. Watch at 2x speed
I had 3 batteries that would not charge at all, considered replacing them or getting a whole new set.
This video saved me alot of $$, all three are now charging and working. Thank you.
You are THE MAN!! I bought a Ryobi drill-driver a couple of years ago which came with two batteries - one was DOA. I got busy and forgot about it until this video somehow came across my feed. I followed the directions and the battery is FIXED!! Thank you!
That exact circumstances happened to me bought the drill & 2 batteries CA,one of em didn’t want to take a charge, it does now
Just tried this on a battery that was sitting in my Ryobi garage door opener and it drain my battery. It CHARGING now!! Thank you.
I tried other methods from other videos, nothing. Your instructions were not only the easiest, but the most effective. Thanks! This worked in less than a minute.
I previously repaired my ryobi batteries without taking the batteries apart and just using the contacts on the batteries and a battery charger set on 2 amp. Theyve been working fine for over a year now.
And thanks.How long do you leave the battery charger on
I too, used my automotive battery charger, @2 amp setting. One minute only needed to get the Ryobi 18v and Black& Decker 24v 'primed.' Full enough to get each respective charger to launch!
I left the battery in charge and switch off the mains by mistake. Battery voltage was showing zero without opening the battery. After opening, internal terminals showed 4.5V. Made a connection as shown in video, internal voltage went up to 14.7 in couple of minutes. Put it back together and tried the charger. Its worked like magic. Thanks a lot for the assembly video.
I honestly didn't think this would work and I was highly skeptical, but what the hell I got out the battery tester came out at 4.7 volts hooked up my charger and set it up 3 minutes later it tested at 7.5 volts. I disconnected it and plugged it into the ryobi charger and sure as shit it started flashing green! 😎 after 6 months of it flashing defective and not charging it took a 3 minute alternative to fix it. Great job 👏 I'm very happy I found your video!
It worked. Battery showed .2v. Took it apart, checked the battery itself, it showed 3.6v. Put the leads on for about 15 seconds. Battery was now at 12.3v. Put back together. It charged and I’m using now. Thank you so much. Saved me a few bucks.
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 !
Yeah, but mine is almost fully charged, and will not activate any of my Ryobis... 12v charger will not charge 17v pack. But will a dead one, yes.
Exact same as I did to 'prime' my 18v and 24v; both were dead 5-10 years.
you can also use two 9volt batteries hooked together in series (18-ish volts) and jumper them to the board. this was a great tutorial. Thanks!
Do you need to bypass the controller board with cover off or can you simply connect to a charged battery?
yes, this is why the battery must be disassembled in order to bypass it otherwise, you cannot send power to those cells.
just done this on a 5.0 ah 18v ryobi battery -----worked great-----saved loads of money ----many thanks.
I have just put about 12 Ryobi batteries in the recycling bin. I wish I had seen this before I did. A question: Is it essential to open the case to get at the terminals, which I assume bypasses the controller, or can you just connect + to + and - to - using the terminals on the posts without dismantling the battery pack? Either way, thanks for the video. I'll try it when the current crop of very expensive batteries plays up.
yea, have to open the case to bypass the controller
Did it today on a 5 year old battery that I haven't been able to charge for over 2 years. Works like magic! What seems to be one possible cause of the Red Light of Death is when your batteries are exposed to cold temps for extended periods of time. Now, 6 of 6 batteries still running strong. Thank you so much!
Ironically, I made a youtube video praising Ryobi and then one of my batteries went defective. Thankfully, my bummer was short lived. This method worked quite well. I was able to unscrew 4 of the 5 screws with a normal torx bit. I drilled out the 5th and replaced it with a standard Phillips. Looks janky but I'm back in business!
Hmm.. ...u..James odonnell. James odonnell to
Thank you, it worked on a battery I’ve had in the back of the garage for ages. Workers a treat and only had to connect both for a few minutes.
why so many dislikes? This worked perfectly for me and will probably work for a lot of different batteries :)
I've used this method to jump start 3 Ryobi batteries that I had given up for dead. They're not cheap, so this has saved me quite a bit. The only investment was about $10 or so for the alligator clips (and the T10 bit to disassemble the case). Thanks!
Thank you work perfectly thought I had to buy a new battery
Thanks for this! I checked one of my batteries that wouldn't charge. It measured 0.6 mV! After 15 sec of charge it went to 7.1 V. Put it back together and charged successfully!
worked exactly as he explained it!!! thanks for saving me $70
Update: it worked. Brought it up to 12v. Now it is charging on its original charger. Ty very for posting this video. You’re awesome!
Your video is way in depth. But in the end it worked. Thanks for the post
Hi Brent thanks for your re-do it's very helpful.Sorry if I was a bit terse in my first comment but I have limited myself to half an hour a day on TH-cam. It was getting out of hand with me especially under COVID lock down.I needed to start actually doing things rather than watching others doing things.Thanks again and Happy New years.
Holy shit I jus realised I'm doing that. Well I did make a floor deck this morning so I'm not that bad
Just wanted to say THANKS! Was able to get my battery working again.
wow thanks left a ryobi battery in the car on my ryobi buffer went to use it dead plugged it in, went back to check it next morning nothing thought crap saw this tried it now its charging thanks so much plus so much fun when you put the possitive to neg by mistake damn eye sight
I just fixed my battery thanks to this video!
Just did it and it worked.
Thanks brother saved me some cash that's for sure.
You have to charge each individual cell separately. These battery packs charge all the cells in series which quickly leads to unbalanced charging. The computer board is only for safety.. it shuts off charging when any single cell reaches max voltage..
This video process didn't work for me. Did you ever figure it out how you charge your Ryobi batteries? Do I need to charge reach individual cell separately?
Thanks guy it worked and saved me some money
Thank you so much! You just saved me having to buy a new battery.
Careful when using a ryobi fan. I discharge a battery below the min voltage by forgetting I had it on. Did your trick and revived the battery. Thankyou
Worked perfectly June 19, 2022. Total of about 30 seconds of connection necessary to get it past threshold... Seemed to want to be above 15v to catch a charge from a charger but I tested only a few times during process, once at 7v, once at 12v, no dice, third time at about 15.5v it caught and charged. Donor battery was at around 19v. Lesson learned with cheap stuff: take batteries out when not used.
Awesome. Fixed my 5 batteries tonight with your help. Thank you very much for the help.
This is the best fix I've seen! No chargers needed, just another battery and some gator clips! Thank you!
Fixed my battery after 3 years dead. TY
Thanks for Sharing. I was able to fix my Ryobi Battery.
i learned a lot of that i didn’t know about the batters from the video.
I got tired of watching and waiting you must be a teacher who has all day
check the description for an updated video. This was the first video I ever made....
I couldn't fix my battery and gave my Ryobi drill away. Mine wasn't the one series. There's a logic board above the cells as you probably saw. That's what's bad on mine. My model drill was discontinued, so I bought a DeWalt.
It worked great! So happy you made this video...
Even if it is not connected to the drill, the Ryobi battery discharges it self with severe voltage drop that makes it impossible to recharge. I open the case as you have done and then use a car charger with 12v to jump the voltage of Ryobi battery to 5-6 volt, by connecting it to the Ryobi battery internal terminals for few seconds only. Make sure the polarity is correct. Count to 7-10 and then disconnect. After that the Ryobi battery can be charged on its own charger.
Thanks - I was wondering why not use 12volt battery charger to do this. I guess the actual voltage from the 12v charger is more like 14v (or slightly more) so your 7-10 count is probably good advice.
I set my vehicle 12v battery charging unit to 2A, attached - & +, left it o n e minute. The 'prime' of the cells then launched the Ryobi 18v and the B&D 24v. Work perfectly.
Easier fix. Battery showed no voltage, I made two jumper wires one for positive and one for negative and put into top of battery were it’s marked positive and negative. I then attached the two wires to my trickle charger and charged for one minute and then disconnect wires and trickle charger .ohmmeter shows10.2 volts. Put in my ryobi charger and now it’s charging. Easy peasey.
I have found that if you just put the battery in its charger, plug in & out to the electrical socket quickly, say 8 or 10 times, the battery will charge normally after that. Worked for me several times with several different amperage batteries.
Brilliant video. Worked perfectly for me. First time. Don't watch the idiots that drill holes in the casing! Even if you just buy one T10 screwdriver specially for the job it's worth it doing it this way.
Y not, jb weld does a beautiful job when your done
The holes are fine, just a slow drilling and stop as it eases up. Pos tab is thinner!
Thank you!! This saved me from buying 2 new batteries!
Thanks for this info. It worked for my battery.
Glad it helped
That is the same impact driver (P234g), I'm still using today, I use it with a Ryobi P108 4Ah battery and it still kicks ass!
Still using it here as well, been a great driver.
worked great - thanks for the comprehensive how to do -
What are your thoughts on the ridgid lifetime service agreement. Internet seems to have good successes and also bad stories.
It sounds good but I have not had to use it yet.
Worked like a charm. I had gone on vacation and forgot one of these batteries in the charger for two weeks. Using the good battery and following your video, it only took 5 seconds of charging to revive the 'dead' battery. Caution: the positive wire gets hot! use needle nose pliers or some similar thing! Thank you. I was about to order a $40 battery.
My screws has a small metal post in the middle of the head which prevents the T10 from engagig the screw head. Any suggestions how to get around that?
Thank you for the tip. You saved me money
Were the Torx Screws always the security / anti-tamper style that take the special 'hollow-point' screwdriver?
Two of my Batts were about 2v. The smaller one: My motorcycle trickle chargers come with mini jumper cables. With the bike running, (14V) I shocked it enough externally to start charging.
My larger Batt, no go externally. I'll open it up and try it. It's actually the battery that I wanted to repair. I
yes, it was a tamper proof torx.
Hello and thanks grate president you’re good I used to do this end more trike methods
I’m ( X Marine ) i lost some of my left lag put it’s all good thank you For Sharing !!
God Bless !! Thanks
This advice works. I tried others but the key is the 2 terminals used.
Just a safety tip here, it’s a bad practice to hold uninsulated alligator clips with both hands to complete a circuit. It appears his clamp had an insulated tip but if you aren’t careful your body can become part of the circuit up one arm though your chest (and heart) and down the other arm. Use insulated alligator clips or some insulated gloves. Or just use one arm at time.
@@ndandthecave456 It’s a bad practice because if you get used to doing it on low voltages then you will do it when working on higher voltages that can kill you. Then it’s not so funny anymore, is it?
Worked like a freaking Charm! Thank you!
Worked perfectly, thanks.
Thanks, helping me understand how this happens.
I think it worked. I've now a second light flashing, before only the first would be steady on the battery indicator. The charger is flashing 'charging'. I had 12V and it was too low too charge. The terminals were showing about 3v. I left the battery in the drill with minimum charge. Now I take the batteries out when put away.
Thank you very much go on after it got two of those little ones I’ve always said we’re garbage didn’t seem to do much of anything drive for screws with it and it’s done and then you have to charge it and it’s not too long after you buy it but it won’t take a charge that makes perfect sense thank you
Worked like a charm!!! Thank you!
Worked great thanks
It would’ve been more effective at convincing me that this method works, if you had shown us a battery “fix” that lead to showing us that the battery actually functions, by powering your drill. Why did you choose to go the route of showing us a clip of a battery that DIDN’T power the drill, after the “fixing” of it?
Yea I've got 2 that test bad, one that the red light just flashes like it's still testing and another that the charger thinks it's fully charged but it's only at 1 bar on the built in indicator. One of them only worked a few months before it quit on me.
My Ryobi One+ 18v Lithium battery measures 15.79 volts with the outer jacket removed as well as prior to removing the cover. I have only this one Ryobi battery. How can I charge it enough so that the controller allows the charging port to begin charging it?
I have a brand new Ryobi Sawzall that I bought right after Hurricane Ian. I used the tool but with my older batteries. Tried the brand new in plastic bag Ryobi 4AH cells and neither will take a charge and it just flashes red.
Thanks so much, worked just as you said
thank you it was so easy enought to jump start my battery i almost throw this one away! i figure i check out youtube before i trash it and sure enought.
I mean the battery has warranty, why not send it back for a replacement? If it’s past the warranty I see how this would make sense. Also, the instructions say to not leave the battery attached when tool is not in use.
Hi - yes, they're out of warranty by now and typically I don't leave them plugged into the tool for more than a day or so while using it.
Why did you need to take the cover off?
I would have put the battery on the charger to show it taking a charge.
I have this problem.
The battery controller on newer One+ batteries drops the terminal voltage down to about 7.5v after about one minute of non-use. This may have been done to reduce the discharge leakage when left attached to tool. It pops back up to 19v when higher current is drawn by tool.
When I first saw this low voltage I thought the battery was bad, but it ran the tool fine.
Came here as I have two that won’t charge. One shows 5v on the post contacts and the other 8.5v. I opened the case as you show. On the battery itself, it reads 20v. Why then would it only show 5V at the contact post that inserts into the tool? A working battery I have shows 20V at the post. Does that mean the issue is with the controller board and that the battery cannot be recovered ? Thanks.
bonjour, j'ai le meme probleme que vous, avez vous trouvé une solution à votre probleme, merci
I followed this method, but had to drill holes on the side leading to the positive/negative plates; based on another video I saw because my screws were stripped. Anywho, doing exactly what he said, that allowed it to to charge successfully, and achieve a solid green light; which it would not do before. But when I plugged it back in to my Ryobi drill would not power the drill. The multimeter registered at 10v... So it's charging now, but it just isn't making it to 18v... Any suggestions?
Mine said 18.7 but still didn't work. Kept putting it on charge for 2 seconds take it off, did that about 50 or so times. And now it holds a charge n works fine again. Idk read it somewhere
Thanks got me started
Appreciate you Sir
Worked like a champ!👍
Glad it helped
I worked...thank you sir you saved my some money.
Can just plug your crock clips directly to battery charger and charge the cells by passing the circuit board
I am not sure because the other battery also has a bms on it, but I don't know if that helps avoid any potential issues by bypassing the bms on the dead battery.
thank you for that sharing
The whole idea here is to take apart a battery that will not charge. Bypass the BMS. Connect another similar working battery in parallel with the raw battery pack to bring the raw battery pack up above the BMS cutoff threshold. Then quickly reassemble the battery pack and put it on the charger. This is the whole problem with BMS's. They work on assumptions and do not actually measure internal resistances of each cell. Thus allot of good batteries get thrown away and recycled in China.
Now that did not take 16 minutes to explain. Brent you need to prepare better before making videos.
So does the charging battery need to be fully charge? If so is there something else you can use because both my batteries are dead.
I have a 5.0ah battery that's not been able to charge for over two years and has been sitting on a shelf ever since.
When plugged into charger, both green and red LEDs would flash constantly.....DEAD!
I was about to recycle it today whilst having a clear out, but figured I'd have a look to see if it could be fixed.
I tried the other method first, connecting alligator clips to the charger terminals and battery terminals, bypassing the safety circuit and nada!
Was about to finally dispose of the battery and then found this video and figured I'd give it a shot.
Battery was @ 0.300v (IIRC) and after connecting for a few seconds using this method, the faulty battery was @ 12v, tried a few more time and got the battery up to 15.8v.
Plugged into charger, the red LED flashed a few times, then swapped over to the green LED flashing! :)
Hope it charges! :)
Powerful and gets the job done.
Pretty good of ryobi to allow access inside the case
Thank you I'll give it a try got 5 batteries are dead
Did you connect the red positive from the dead battery to the positive on the charged battery?
How would we by pass it if we don’t have another battery to do that can I use rechargeable AA Lithium batteries?
One+ 18v lithium battery’s won’t charge. Followed your tips. Prior to charging it had 0.10v charge. After following your tips it is now 5.88v. Placed it on the original charger still won’t charge. Any other tips? Should I bring it up to 10v? Ty
This worked for me on a 3Ah battery 🔋 🔋 👍
I've heard a rumor that RYOBI will replace a "dead" battery for free as long as you have not messed with it. True/False? I have several that will not charge, but the green charging light comes on. Seems that RYOBI would have fixed this problem years ago. The charger should detect a too low battery critical condition, and when it does, it applies your fix. Simple solution. Another fix would be installing a buzzer in the battery that activates when the battery is near the no-charge point, say 7 volts; this solution would help prevent you from letting the battery enter that low battery volts/no charge condition. For what these batteries cost, this no charge situation should not be allowed to happen.
It must at list be not blinking on the last battery bar so it will charge I tryed it but no gater clamps straight wire red and black but it work same steps
