How To Revive A "Defective" Ryobi Battery

[@microfab11]

You are a genius. Just revived my Ryobi battery using my portable jump starter battery. Held the red clamp to red and the black to the other side of the battery as shown in the video. After 30 sec, still low voltage, 30 sec more, 3.8V across the battery, still shows defective on the Ryobi charger, 1 minute more on the jump start battery, 9.2 V across the Ryobi battery, plugged into the Ryobi charger and it flashes green. Thanks.

[@TheBeardedJeeper]

Jim Harper awesome man glad it worked for you!

[@stuartmclaren2402]

I have had a problem with the Ryobi charger, and I blamed the batteries. So I bought Dewatt set which is tradesman quality. It was only when I went to the Ryobi seller and discussed it, he invited me to bring the Ryobi batteries and charger into the shop. When we tried the charger in the store, it worked with my batteries showing my charger was faulty. So now I have 2 working Ryobi and 2 Dewatt chargers. So if a problem with charging, do not automatically assume it is a battery issue. We can often find Ryobi and Dewatt in second-hand tool stores quite cheaply so to get additional chargers, I took good batteries into the store and requested I test the chargers before buying. Another problem here is that the Ryobi importer will not supply spare parts. For tools like chainsaws, lawn movers, etc, service and repair shops won't touch them. When I asked what we do if not under warranty and need a small repair, I was told we buy a new one. This is highly unsatisfactory as for DIYers, we often don't use some tools that often. So if buying such tool sets which lock us in with batteries which aren't exchangeable with other brands, I have learned to make some inquiries first.

No need to disassemble battery. Simply attach leads of trickle charger to exposed contact points with a wood clamp. Left on ten minutes. Placed in normal charger and perfect. Thanks for idea!!!

On the charger and charging! Thanks for the info. Yup, I believe the disassembly is required to bypass the board, which is what was preventing any charging in the first place. Once the leads were hooked, the charge quickly went from 11V to 17.5V, when I stopped it and plugged it into the charger.

Thank you! In the course of 1 hr I recovered a Ryobi, 18V, Dewalt 18V and a Black & Decker 40 V. I probably would have gotten new tools instead of batteries for the DeWalt and B&D since they are 10+ years old. 3 of the B&D were dead. So you saved me more than the cost of the batteries because I would have just replace the tools.

[@davidvrablic5999]

:oltage bump has to be done on the battery side of the bms charg / discharge circuit. CAUTION Only for a few seconds at a time. Check with a voltmeter usually needs overv 10 vdc. To charge If stubborn give it 3/5 seconds, check voltage, wait then try again. If to much for too long you may get heat, damage and fire.

[@otterpopjunkie]

PSA: deep discharge and subsequent charge of lithium batteries can lead to fire. Act accordingly. I've found the Ryobi batteries will kill themselves if not fully seated in the charger. Also do not continue using them once they start to slow down, swap or charge. That will prevent the voltage from getting too low to charge safely. You can also buy new 18650 batteries and replace them. Did that to a old pack and it's better than new, since battery capacity has grown significantly in recent years. 👍

I know you said 30 seconds. Using a meter, I found out that if the battery comes back less than 8 volts, it's not going to charge. The ones I had were in the 5 volt range and one was at 3. I connected my trickle charge to them, the ones in the 5 volt range took several minutes to get up to that 8 volt area. I monitored it with my meter and could watch the voltage climb. The other one that was at 3, it climbed very slowly but left it over night. This morning, it was at 9 volts and I put it in the Ryobi charger and it's doing its thing, blinking green. I've got one more to go (had a total of 3 of the P102 batteries)

I bought a drill last week and love it but the battery charged once then played up. I watched your vid then inspected the contact points in the charger. I bent them out a little and viola.

I know one thing that causes this problem. When your tool stops do not try to use it even a bit more. Stop what you are doing and change or recharg that battery, like thebman said if the battery volltage gets below what the battery management system (BMS) allows . You wiill have to do this trick to get it back over the charging threshold. Charge your bathroom teries more often and pay attention to those with the built in level meter. MY 2 CENTS. good vid!

0:50 I think that ryobi charger kills ryobi batteries. I’ve had a few batteries I’ve put on to charge, they charge fine for a few minutes, but I come back hours later and it’s flashing and the batteries don’t work.

[@johncoops6897]

That happens when the total cell voltage is high enough to initiate charging (green light) but then the pack is detected as not accepting a charge properly. Therefore the charger terminates the charging process, creating the red lights. That situation is caused when one or more cells in tbe pack hsve failed, and the charger deliberately stops charging them to ensure that there is no chance of fire, etc. So, the battery pack is failed and the charger is NOT what killed it. You can replace the cells and create a refurbished pack, but its a lot of work and can be costly because you must use 5 or 10 matching cells (you cannot just replace one faulty one). You also have to use so-called "high amperage" cells that are suitable for power tools, you cant just use any old laptop 18650s. You need to check the specs of the original cells and make sure you replace with cells of equal or higher "maximum amps current" - the 5 cell packs need higher rated cells than 10 cell packs.

Mine remains a mystery. It is a 4AH Lithium Ryobi battery. I topped it off to get 19.7 Volts at the batteries and at the terminals, but when I press the drill's trigger, the voltage at the contacts goes from 19.7 to zero while the batteries themselves remain at 19.7 V. So the twitching circuit in the battery pack is going open circuit upon the drill loading it. Do these suckers have a counter that times out and renders the battery pack useless? Is there there some other system involved in operation?

[@derikhulsey8093]

You can jump individual cells in the pack using a second (known good) battery. Using jumper wires with alligator clips, jump a single cell that is low in charge to a known good cell on the good battery. MAKE SURE YOU ARE CONNECTED USING PROPER POLARITY!!! (Positive to Positive, Negative to Negative) Use a digital voltmeter to keep measuring the voltage of the "low cell". When it reaches approximately 4v, do the same for any other low cells (but make sure you jumper to a different cell on the known good battery so as not to drain that cell too far. Once all of the cells on the bad battery are over 4.001v, you can then put the battery in the battery charger and it will then charge it. NOTE: Each cell can take a few minutes to charge up to 4v, so make sure you keep it jumpered long enough to get the cell's voltage above 4.001v. I had a P107 battery (showing only 2 LED lights after the charger said it was fully charged) with one of the cells at 3.5 volts and all of the others were above 4v. Using this method allowed the battery to take a full charge again and showed 4 LED lights again.

Genius! Worked for my 18V

[@TheBeardedJeeper]

Darren Brown awesome! Yeah I found it works most of the time. Sometimes they don’t work but probably 80% of the time it does

[@crabbysam]

The problem is almost always one of the 18650 lithium ion cells is degraded. This fix they show won't be a permanent fix, if you swap out the bad 18650 cell, its the proper way to rectify this.

[@TheBeardedJeeper]

how do you check to tell if a cell is bad?

[@jerryvang3601]

@@TheBeardedJeeper Use a multimeter to check the voltage readings. It is usually one or more of the 18650 cells that's deep discharged.

[@TheBeardedJeeper]

Tony Vang I’ve seen it be all Of them low before too but yeah a multimeter helps

[@mikecho7136]

yup just opened mine and found one of them was degraded. it was barely used before it died on me...super annoying

[@user-jv9qz2bu1r]

My P108 has in one corner a "plug" where a screw might have been. How do I tackle this corner? Also I removed two screws but the 3rd is stripped. So I only freed up two of the corners. WHat do you think?

[@TheBeardedJeeper]

The plug should just be a cover screw underneath how did you strip it use a normal screwdriver?

[@user-jv9qz2bu1r]

@@TheBeardedJeeper No I used a torque but it was one size too large or small the head must be soft metal ,,, then when I found the correct size the other two came out easily ... ok will pop the "cover" off ... if I can remove 3 of the 4 screws maybe I can pry that lid apart

BTW I subbed!

@@user-jv9qz2bu1r thank you 🙏

[@royengle]

P108 has paired batteries. Hence, the front paired battery was bad--replaced them. Packed now charges.

[@TheBeardedJeeper]

Good to know. Thanks

[@mr.doobles5026]

I don't have a trickle charger, only a booster pack... Kinda wanna try it with what I got any way.

[@TheBeardedJeeper]

It should still work just try it in small increments

[@posplaytime801]

My 18v battery actually shows full charge at the cells but the post shows zero. Any ideas? Thanks

[@TheBeardedJeeper]

I’m not sure I’ve had a few do the same thing and I just got rid of those ones

[@kickflip10118]

Thanks for the video, man. When I measure the voltage using the external positive and negative it reads 6.9V but when I open it up and measure the voltage on the internal positive and negative, I get 19V. Do you think there is a different problem I’m having? Thanks.

[@TheBeardedJeeper]

No sounds like you are doing it right

Worked for me. Thanks

Neat - worked great!

Awesome thanks for watching

[@wisecampmotorcycles8258]

My battery takes a charge, but only for like 5 minutes, then when I use it, it dies after a few minutes. I'm thinking one of the cells is faulty. I was thinking about replacing all the 5 cells with new 18650 batteries?

[@hikingwithphoenix9442]

Worked for me! Thanks

[@Alanoursl]

Why can’t you use the terminals on the outside?

[@TheBeardedJeeper]

I’m not sure I think it just gives it a better jump from inside. I’ve tried without opening it but no luck

[@nathanhale7444]

My packs are still at around 18 volts but aren't getting anything to the contacts. I think my boards are bad.

[@TheBeardedJeeper]

Very possible. This trick doesn’t work 💯 of the time but is nice when you need to save some money and it does work.

[@Stickkid5]

So basically what I got from this video is just go buy a new one

[@TheBeardedJeeper]

Sure if you want to spend 50-100 bucks.

[@powerthoughtsontools4831]

I found a biggish orange Ryobi pack(3amp??) --My two questions:(1)--Do you think this is a nicad type?.....and,(2) Is there a certainty on yor part that I would need to take off the shell to hit those inner contacts,( bypassing the b.m.s) As, this is a found pack, I'm guessing the person disposing it may not have known this trick. I have pulled this trick off with Craftsman 19.2nicads to great success.

[@davidhoosline1450]

Where do you buy the tool to take the battery apart?

[@TheBeardedJeeper]

you can find them at any place that sells tools. I think they are called security bit drivers or something like that

[@icekiller181]

Why you cant use the top battery pole without unscrewing it

[@TheBeardedJeeper]

I am not 100% sure I think it might be part of the thing that won't let it charge if it is a low voltage. taking it apart and putting the charge right to the battery cells seems to do the trick
