Ryobi 40 volt battery reset.

- Опубліковано 25 сер 2024
- I had 2 batteries with 2 different problems. One was dead and wouldn't charge. The other was fully charged but wouldn't run any tools. This simple reset process fixed both issues. It's an easy fix, no extra power supplies or voltage regulators like I had seen in other videos. I hope this helps someone else. Just be careful. These lithium batteries can explode like a plasma cutter.
Update: One of the two batteries wouldn't charge again. I tied this same process and it didn't work. I guess they don't last forever..........
This worked like a charm. I made a warranty claim on the battery today, free replacement, then sat down with my T10 bit and opened that case up. My battery model has two small holes next to each other with RST printed nearby. I tried jumping with a flat head screwdriver with no effect. I happened to have a twist tie on my table, peeled off paper on two ends, and stuck those wire ends in the reset holes. Four green lights turn on solid, remove the twist tie jumper, push the battery test - one green light. Put it on the charger and it's happy as a clam. Now I'll have TWO 40v batteries ! BTW, my failed one was factory reconditioned. I don't think it was wrong to make the warranty claim and then fix the failed battery.
Hey Jeff -- a big thank you. My battery was flashing defective. I watched several videos -- one more complicated than the last -- then I watched yours. I was so excited to try it. My 40v battery was already opened, so I grabbed a paper clip (any wire will work) and used it to jump the 2 points you described (reset and 3v) and, in 3 seconds, my battery flashed green once. I reassembled it, then put it back in the charger and it came back to life. It is now getting a full charge. Awesome piece of information. Thank you. You just made the world a little bit better.
That's awesome!!! Good thinking!! I never thought that a paper clip would work!!!
My battery pack had the same problem whereas it was fully charged but wouldn't run my trimmer and no lights when pressing the test switch. My pack was under warranty so Ryobi sent me a new one. I decided to try the reset on the old pack and it worked like a charm. My circuit board is different from yours but I was able to find the very small printed RST holes and jump them with a screwdriver. Thanks for the great tip.
I did the same thing you did. I watched other videos and just looked for the RST connection on the circuit board. Trial and error......... sometimes we get lucky........ :)
Thank You! This is the most helpful Ryobi video on UA-cam.. Thank you! We fixed our $160 battery with your help! Score!.
Thank you so much for showing this on an older battery. I couldn't find the reset on my older Ryobi until you showed this. Been looking at all the vids but they were all on newer versions...guess mine lasted longer than most.
Came across this video by accident. Figured, what the hell. Tried it on a battery I had that wouldn't charge. It worked. Put it in my trimmer and perform like normal. 👍 thanks. Really appreciate it.
I'm glad it helped.
Nice. I couldn't find the reset button until this video. :-) For me the GND and RST was the key to reset it. Battery is now charging after the mower took it way below charge. Testing it tomorrow!
Hey Jeff. Tks for vid. Now the update. Took off 4 screws with reg sm, star bit. Separated/Folded back plate (little stiff) like a book (no need to pull off/back touch pad). Took 2 metal scribes, put in "Rst/other hole" then crossed them to make contact. Same time pushed "internal" button (where pad actually hits) & 4 lt's went to one. Put on charger with plates (top/bot) together. Charged up in 2hrs. Put screws back in. Tested like new. Hope this helps others, your's did me a solid...TKS. Ps, didn't have jumper stuff, hence metal scribes.
Great video. Simple. Mine was a little different but same concept. Found the rst holes and jumped it with a paper clip. All for 5 dollars ( had to buy the bit). Took me less than five minutes.
Amazing! Mine was a totally different layout as well... 3.3V to Reset worked like a charm.
Thank you, friend!
Thank you so much! I watched other videos and my circuit board was different than all of them. Until I watched your video, I did not know what to do. Thanks for the help.
This worked for me. The lights never flashed during the reset jumper, even when using the status button. When I completed the reset and retried it the battery came out of the frozen state. Now fully charging and works well - Thank You
Worked for me, was one of the newer 40v batteries.
Solid green light, would not charge.
Reset it and bob’s yer fathers brother!
Thanks for putting this tip up!
My pleasure. I discovered this just by trial and error using information from other videos.........
Thank You! This is the most helpful Ryobi video on UA-cam.
Thank you! I was feeling the same pain. Different batteries from everyone else!
Thank you so much, all I did is short the RST holes, you’re a life saver. I appreciate you
Thank you thank you. I had the same problem. Every video had the newer batteries. I have the older OP4026. Different board than the newer ones couldn’t find the rest button. Lots of help.
I have the exact same circuit board on an older battery, a small 1.5 amp hour(I think) from the first model string trimmer in 40v. The motor went bad and faulted the battery. $40 for a new motor and it works great! I did the jumper reset trick and nothing flashed or blinked. But I tested the voltage and it went from 3v to 13v. Put the battery on the charger and it blinked green without showing any error. After a couple minutes I tested the voltage again (literally as I'm typing this message) and the volts went up to almost 15v! I'm going to fully charge it now and I think the battery is fixed as well!
Thanks for the help :)
THANK YOU SIR! Worked like a champ. had three dead ones. all are charged and working.
Excellent! Just what I needed. I'll try it tonight and report later.
Thank you! We fixed our $160 battery with your help! Score!
Didn't exactly work but it gave me just enough of a clue to reset the battery myself. All I did was short the reset "tab" to the tab next to it and it worked, so thanks!!!!!
Thank God I found someone with the same board as mine. Up and running!
I haven't had any problem with my batteries, but I appreciate the knowledge.
Thanks so much,, was opening my battery up as I watched your video, exact same layout,,
Had same problem with my 40v and did exactly as he showed and it fixed mine as well. Ty for your help 😃
thanks i was able to fix my hart 40 volt battery using all the steps they are different it's the same concept i had dual RST AND 3.3V and jumped them at the same time and it worked. No more blinking blue light and started charging with your charger...thank you...💪
Thank you, looked at many videos but this is the same layout as mine. I reset it, put back on the charger. Its flashing Red due to very low voltage, fingers cross I get the flashing green light soon.
Thank you. I have the same board. I bought 5 bad batterys for 30 bucks. So that's what i needed to know
Thanks. I love a 20 minute Video done by a smart 'tuber in 3:40 !
Thanks for the up-close video, very helpful! My Ryobi 40V 6hA stopped after only 3 uses. I got it replaced through the warranty program, but hated to just get rid of the old one without attempting to fix it. I watched several videos, but yours was the only one I came across that gave this much detail of the circuit board. For my battery, the 3.3 to Reset jump didn't work, but the GND to Reset did. It's on the charger now. Only cost to me was a trip to Harbor Freight for a set of Secure Torx to get the cover off. Size ST-10 worked.
Tôi gặp tình trạng như bạn đối với pin ryobi 40v 6ah. Bạn có thể giúp tôi cách khắc phục
@@thanhpham1320 after getting the battery open, I found the location on the battery circuit board that had labels for GND, 3.3, Reset. I used a jumper (paper clip) to touch both GND and Reset at the same time, and it worked for me. Good luck!
Is that it? Should I be pushing a button or have it on the charger while jumping it
Thanks from Australia for your video. I'm about to try this technique. I'll report on success or not later :-)
Thanks for your info,very simple fix.
Thanks just did this. No led light blinked. I did RST and 3.3v and RST and GRD. So far its charging. My issue was the leds shows full charge then no charge so definitely one of the cells was not charging.
That’s the exact battery style I have and thank you!!!❤
I have a op40602 40v 6ah battery, although the reset is in a different location, I was able to find it and it worked for me
I’ll be damned. Worked like a charm and saved me $150 or more. $13 for a security torx kit to the screws out.
Thanks for this video. I just tried it. May have worked. I am testing it now.
Worked like a champ!
Worked! Thanks a bunch!
Also, I was able to drill out the “safety “ dimple on the torx head with a small drill bit. It didn’t take much drilling and I was able to use the regular torx bit.
good video
saved me over $100!
Glad it helped you!!
Thank you 🎉
Worked for me. Thanks
Anyone know what size screws for 6ah version? 2 of mine have vibrated loose over time and disappeared!! (it was dead, not charging and I used reset method and its working now!!)
thank you from march 2022
worked for me. Thanks!!
good tip Jeff
My board lacks anything “RST” . It’s from a 40v 12ah battery. Unsure what to do next
Very good video. Thanks
Thanks
You need to get a tripod youre shaking like a leaf. Good vid
My first instructional video!! I did get a tripod for any newer videos should the need arise......... I only made this video because none of the others I watched had my same battery..........
For dummies, please. What are you connecting the copper wires to, to reset the battery?
I don't know what to tell you man. I think I explain it pretty well. You're taking a piece of wire with a solid core and touching the points that say RST and 3.5 to essentially make a connection for just a second or two.........
Does anyone have one with Ryobi Gen4 V1.4 board? Tried to look for rst pad but none to be found. Battery model OP40404
So many different boards on the various 40v Ryobi packs. One is like yours, another has the rst on the side and a 4th one I can't find it. I did see a new board on amazon and snagged one, but looks like way to far above my skill set for soldering/unsoldering.
My 40 volt battery (OP4026) says it is charging but does not charge more than 2 lights (on one battery) and 3 lights (2nd battery). Both batteries came with the 20 inch mower in 2015. When I used one of the batteries in my blower (variable speed), it would blow for 10 seconds and stop, then blow again and stop. Ryobi told me the batteries were not defective because if they were, they would have recalled them. HAH!
The voltage (19V) between the + and - should be sufficient to run the blower.
Once the screws are removed, how does the case separate?
pry it open at the seam, and lift up the sticker for the battery indicator at one half when it starts to open.
I’ll try it
LOL.. thanks for the vid and the laughs "alligator clips and all that crap"
Jeff, you are super human
LOL!!! Hardly, just cheap when it comes to this kind of stuff....... :D
Thankyou very much ,😀it’s working
Thanks I got it working
Do you have to poke the wire or paper clip deep into the hole? I'm trying both reset with 3.3v and reset with GND. Both not working.
No, just touch the metal around the holes, and hold it there for a few seconds. But you have to make sure you're touching those points alone and not touching any other metal point. I know it's a tight area, but it can be done.
The ground has nothing to do with resetting. You just want to touch the 3.3v and the reset points at the same time and hold it there for like 5 seconds
CAN YOU PLEASE TELL ME WHAT TYPE OF WIRE OR WHAT YOU USE TO JUMP IT WITH PLEASE GOD BLESS YOU HAVE A BLESSED DAY IN THE LORD
Any solid core wire will do......... I believe I snipped that piece out of some regular 12 gauge house wiring I had lying around in the garage..........
Thank you.
I have the same board. Unfortunately, it didn’t work for me. My battery is out of warranty and it shows 1 light so it’s not completely drained or dead.
Same here
Same here so far. Shows 1 light and multimeter reads 40v across battery. RST is at 3.3v and not 0 also.
Didn’t work for me either. Same board and same 1 light situation.
Same tried grn/rst and 3.3/rst no Luck
Didn’t work for me either tried both RST & 3.3v and GRN & 3.3v. Have one green light on. Anyone else that experienced this found a solution?
How old is this battery? Why not get a replacement under the 3 year warranty?
Have the same battery and tried it, did not work, still trying to reset it
If this is the first time keep trying. I just had to try doing it again on one of the batteries I mentioned in this video, and it did not work. Could be there's a point of no return..........
Non-electrician here) I have an old Dell AC adapter that runs 19.5 v and 3.34 A... will this work to get some juice into my 40 volt neon green Ryobi boat anchor POS? Thanks!
I'm also a non electrician, so I can't answer your question, but I know enough not to want to mess around with anything plugged into an outlet..........
I have the same circuit board. I saw one video suggesting to jumper between GND and RST so I tried it without any success. I also tried RST to 3.3V and no luck. Some videos mentioned pushing the ? button while jumpered, still no luck. I checked between the cells and got the following voltages;
CLI- TO CL1+ =2.8V
CL1+ TO CL2+ =2.8V
CL2+ TO CL3+ =6.3V
CL3+ TO CL4+ = 1.7V
CL4+ TO CL5+ =2.6V
CL6- TO CL6+ = 3.2V
CL6+ TO CL7+ =6.3V
CL7+ TO CL8+ =3.5V
CL8+ TO CL9+ =3.6V
CL9+ TO CL10+ =3.5V
CL1- TO CL10+ =10V
I don't have a power supply but tried jumpering to a good battery for a little boost with no success. Which is more concerning between the 1.7V low reading and the 6.3V high reading? Should I try drianing the high voltages with a 60W incandescent light bulb? Any suggestions?
Sorry, but I really can't advise. What you're asking is above my knowledge level. I had to watch other videos of similar but not the exact same circuit boards and I just experimented with the information I got from those videos. Could be I just got lucky, but it's better than buying new batteries when these are just fine...........
Seems like something is wrong there. The voltage should be 4.1 volts between those taps and Cl1-CL10=41ish volts. The board is suppose to drain the high cells such as Cl2->Cl3 down to 4.5v and charge up the Cl3-cl4 cells to 4.1+. You could use a hobby charge with a balancer to charge and rebalance the pack. I did this mine, since my charger only does 6 Cells at a time, I just connected 4 at time. Otherwise you could drain as you said the high voltage ones down then put a 40v charge across Cl1 to CL10 till the overall voltage is higher than 20v and see if the charger picks it up from there.
It can also be that some cells have there CID popped and the voltage reading you see is not accurate until you take cells out of circuit. If cells out of circuit are charged to above 3.6v and RST is done and still not working then controller chips/cct are no good. Option then is to use generic BMS and charge generically. MOSFETs could need replacing. Can be time consuming to replace cells but if you have the time...
@@Swenser Your knowledge seems far above mine, could you please offer some advice on the below (TIA)? I tried resetting mine, but only made it worse. Previously it was charging for around 5 minutes before the red and green started. Now it won’t charge at all, and the battery level indicator stays illuminated always unless I put the jump wire back in. I’ve got the below readings across my cells.
CLI- TO CL1+ =3.6
CL1+ TO CL2+ =2.6
CL2+ TO CL3+ =3.6
CL3+ TO CL4+ = 3.5
CL4+ TO CL5+ =3.6
CL6- TO CL6+ = 3.5
CL6+ TO CL7+ =3.4
CL7+ TO CL8+ =3.6
CL8+ TO CL9+ =3.5
CL9+ TO CL10+ =3.5
CL1- TO CL10+ initially shows 19.8, then shows zero, I remove the multimeter and place back in that same location and it shows 19.8 briefly, then shows zero.
Do you have any suggestions on what you think I should try next?
I want to know where to put a wire on to change it. Now i am halfway there thx to u. I hear the same ol where what it is in hokis pokies
Not sure what you're asking here? I assume you meant to type "charge" when you typed "change".......and what is "hokis pokies"? LOL!!
But you're not going to charge anything. If you watch the whole video, you will see that all I'm doing is resetting the batteries so that it will charge in the regular charger. Follow my directions to the letter and hopefully you will get the same results........
Let me also add my BIG THANK YOU for your video. Your video and a $15.00 investment for the security bits and voila...back in business and saved me $200 bucks for a new one. Excellent presentation. Thanks again sir!
it work to cool thank you
Followed the steps and Got it to charge for 5 seconds then goes back to the defective flashing. Any thoughts? Help appreciate
I would try the resetting process again. But just maybe there are some batteries that can't be brought back. They do need a certain amount of charge in them to start with. I've read that every time you plug a battery into a charger it does actually charge it for that millisecond before it tells you that it's no good. You might try plugging and unplugging multiple times, but by multiple I mean like 50 times......
Hey Jeff, did you get your jumper wire anywhere in particular? Thanks
No, it's just a piece of solid core wire.
@@jefflbi thanks!
I used my 1970 Craftsman needle nose pliers which have insulated handles.
I'm scared to shocks is it safe? Mine charges for 5 min then starts blinking green and red.
As with anything, there is always a risk, but think about it, the battery is so low on a charge that it won't charge............ so common sense tells me the risk is miniscule. Also, look at all the posts claiming that it worked like a charm.......... good luck.........
My battery has four flashing lights, though, will it work on that?
If there's an alternating red flashing light on the charger than I would say yes.
Hi jef I pressed diff holes didn’t no u meant reset ones (u shoulda said this) so I was pokin every where like I was playin operation lol. So it’s all messed up now I called they say to me since I just got it that mornin couda just brout it back to re place. But since u said to go pokin around everywhere well now it’s messed dude. So askin if u mind re bursting me or goin have at least they r not cheap. Thanks jef, ronnie
My battery is fully charged and the weed whacked only runs a few seconds then shuts off
Have you tried this reset procedure?? If so and it still doesn't hold a charge, the cells could just be shot/defective, in which case your only option is to purchase a new battery. There are aftermarket batteries available that are cheaper. I found some on Amazon. They last just as long as a Ryobi brand battery.
How do you get the screws out of the battery?
Go to Harbor Freight and buy a set of “security bits” - cheapest price for brick and mortar. You want a security Torx #10, or ST-10, bit.
Can you just take it to home depot and get a replacement
Sure, if you want to pay for it............. most of the time this happens well after the warranty expires...........
What tool did you use to open it
I think a small phillips head screwdriver. By the look of this video it looks there there are 4 of them, one at each corner. And there is a label you can either peel back or make a slice with a razor blade. In this video I just peeled it back.
Brother RST and 3.3v short pin reset ryobi batterys?
Yes, exactly how you see it done in the video..........
@@jefflbi Thakyou 👍👍👍
Likely should short RST to GND.
What I'd it got wet, is it ruined?
Most likely not. The inner parts of the battery are pretty much sealed from what I can see. It never hurts to give the jump a try........
Mine still won’t work 🤦♂️
Sorry to hear. I guess some batteries are just too far gone. But I would give it another try to make sure you're touching the right connections.
what do you need to do to reset the PCB after replacing the cells.
What is PCB??
@@jefflbi The PCB is the whole PCB.
@@jefflbi what do you have to do to unlock this plate after replacing the links with new ones?
@@tomnewtnt5718 Sorry but I'm not sure what you are referring to............
@@jefflbi PCB = Printed Circuit Board
Just imagine how many batteries have been binned , when in fact they’re good 🤬
How about the chainsaw battery
If it's of the 40 volt variety like in the video then yes, it should work. Not all batteries have the same circuit board, as I pointed out, but they will have a reset and 3.x volt points somewhere.
Ty I turned it upside down and wiggled and it started charging thanks for the help

Well that didnt work
I just had to do it again on one of my batteries and it didn't work this time. Guess they only have so much life in them. Oh well. I'll be buy aftermarket batteries from here on out...........
You never showed which battery you were working on yet you complained about there being multiple batteries! Be clear
Really??? The title says 40 volt.......... they all look the same on the outside. it's the inside that is different........
