@@s.tavares9739 No, If the battery sits too long without getting a charge then you would have to do this again. But, if you do it the first time and maintain the battery, give it a charge once in a while then you would not need to repeat this process. Hope it helps! Cheers! Shu
It works perfectly!! Just cut of the plug from an old 12v power adapter and put both wires to the right place on the battery for one minute. Really happy! Thank you for sharing this.
I took my ryobi apart multiple times and tried to jump start it using the charger and other good batteries and every attempt FAILED... my ryobi battery has been sitting for years and i decided to try your method and it actually worked!!! It's charging right now and I have a green light and my fingers are crossed. Amazing!!!!
Awesome! Glad it was of some assistance. At the cost of these batteries it's good to know that they can be fixed by us. Ryobi and others have firmware that prevents the batteries from being charged once it hits a certain low level and most customers will buy another battery. This way we bypass the firmware. :) Cheers!
Thank you for the awesome comment! I'm still using the same batteries. As they say, One's man's junk is another one's treasure. People want to throw them away, I'll fix them. Cheers!
@@LivingFree365Thanks for the tip but I wanted to ask you if I could possibly do the same thing but with a 24 v RYOBI weed eater battery or maybe using a 18 v charger…??? Please reply and T.I.A.
@@jalanis7 If the battery has a PCB (Printed Circuit Board) then you should be able to. The PCB is what's telling the charger that it's ready to charge or if it is too low to charge. So, I don't see why it couldn't be done the same way.
Sweet, now I can fix my 2 batteries that I have been holding on to. I was even to the point where I was going to order some new cells to install in it but now i see that it may just need a jumpstart to get it to charge. Thanks
Thanks for the great video and information. I watched many others but couldn't remove the cover after taking the five screws out. Yours was the only one that showed how to separate the case using a small flat bladed screwdriver. Turns out there's a small clip on the sides ! Thanks !!!
I sort of did the opposite a few weeks ago, and used a Ryobi battery and jumpers to boost my completely flat car battery enough to have the charger recognize that it was attached to something with a voltage. Don't use thin wires or they'll overheat.
@LivingFree365 Arthritis and Long Covid put the kibosh on camping any more. After a year of not camping, I hauled the camper home and turned in the license plate.
Since I'm retired and a well-known cheapskate AND I have set of bits that includes a #10 Torx I gave this a shot. It took me an hour and didn't work. I understand from other videos that sometimes it works, other times not. So if you try this, would you tell us whether it works? Post a comment saying "It worked" or "It didn't work." If it works even 20% of the time it's worth an hour of anyone's time. If you're retired and have nothing better to do, it's worth trying if it only works 10% of the time. IF you have the bit. But if you work 40 hours a week and free time is valuable, it might be worth a shot or not, depending on what the odds are.
Thank you for the comment and question. The terminals you see at the top don't exactly go to the battery. the ground does but the positive runs through the circuit board. And the cards have firmware that only allows power to go out unless certain processes are completed. (like minimum standby voltage). Hope the info helps! Cheers!
I didn't use a security bit, I just used a hammer and I think a very small nail tap with a nice flat end to smash the security-bits down and then my regular star bit worked just fine- these screws use fairly soft metal. Don't whack too hard of course, it took a bit of patience since I was trying to fix the Battery, not break it! In the end I was able to restore one of my two batteries which has lasted another 2 Years so far. If you do this, just be careful- the plastic on the name brand ryobi batteries is pretty tough, but the knockoffs might not be so forgiving. I used an old 18v laptop charger with the end cut off- so just loose wires along with a multi-meter to charge it up to about 6v, then the regular charger did the rest- it was sketchy. If you go the cheapy DIY with whatever you have lying around way, as I do, just be careful. I do things the poor Man's way kuz I'm a poor Man! Knowledge is great though, helps me barely get by when I've got very limited resources to work with! I love making things last.
Quick question... i have a 36v ryobi dead battery, will a 12v wall charger be enough to jump it or should probably need more like 20v charger to kick jump it?
Hi. Just wanted to thank you for posting this video. I had a 5amp/hr battery that wouldn't work at all in a tool and when on charge would charge for 10secs and then show as fully charged but only 2 bars would be lit. Still wouldn't power up any sort of tool. I tried your method but had no success. I then tested the voltage of each battery in the pack. They all showed between 3.6 & 4volts except for the second last cell it was only 2.8volts. I had a test light attached to the 12v transformer for the positive connection instead of just a wire, when held against the cell on each end the light was turning lighting on my test light so I connected my volt meter to see if it would charge that cell. I found it was drawing from the cell and could see the volts decreasing. For some reason I tried reversing how I had the negative and positive test light that was still connected to the live 12v transformer and found it still lit the test lamp a but only very dull. Tested with the voltmeter and it was charging the cell but only very slowly. I left it charge until it showed 3.6 volts and then connected it to the Ryobi charger. It began charging and stayed charging. Let it run the cycle and put it on the drill and it worked. Have been using it today on the drill and running fine. Fingers crossed it keeps going. Just thought i would share my experience & wanted to thank you again. 👍🏻👍🏻👍🏻
Thank you for your comment. Your insights suggest a potential issue with one of the cells containing lithium. It is commendable that you have managed to rectify the situation. I would recommend recharging it multiple times (2 or 3 times) before reaching the second bar to ensure its sustained functionality. With any luck, it will endure for many years to come. Thank you again, good luck, and Cheers! Shu
I've noticed the same thing with my "rechargable" flashlights. The original batteries didn't last very long So, I swapped them out for some aftermarket ones and they still are going strong.
Thank you! I've been working with the DC side with only a few issues, but when I work with the AC side, that's when it gets bad. Was too close to Death's door the last time I worked with high-voltage AC. But, I will succeed. Glad you liked the video. I'm trying to figure out how to repair the 40-volt Ryobi batteries now. Cheers!
My multimeter says the dead battery has 18 volts but it does not power any tools. When plugged to the charger I get the long testing flashing red light and then get a solid green after that. The battery charge indicator lights do not light up at all. This seems like a different issue, yes? Thanks for the video, hopefully your experience can help me identify my battery issue.
Technically the battery should be 21v fully charged, and 18.5v under actual load. If its reading 18v that means the battery is dead and should be charged. If the charge is SAYING its fully charged then it sounds like one of the 5 cells might be bad and so when you're trying to actually use it in a power tool it will be at around 16.8 volts which is too low. You can either replace the one cell or just buy a new battery. I would suggest if you dont want to replace the one cell to ask anyone you know if they know how to do that kind of thing and maybe they would like to use the other 4 cells for whatever projects they have, so you dont have to throw the whole thing away for just 1 dead cell.

Thank you for the good question. it can be charged normally, as long as the battery isn't allowed to naturally drain to almost no volts. If you just finished using the battery or it goes dead while using it, it will recharge like normal. When the battery test scale flashes all four lights it means the battery is too low to charge. Hope this information helps.
Thanks for the video! I’ve watched countless videos about this issue… And haven’t come across one with the exact scenario, as I am facing… I have an 18V 4ah lithium ion+ fairly new.. When I test the battery with a multimeter on the charging port contacts, it’s showing .5 mV… After taking battery apart and testing the contacts inside the battery casing, it’s showing between4- 5V… tried using a trickle charger today and got negative results… Any suggestions?? Could it be a motherboard issue? Can it be fixed? :/ thanks in advance!
Thank you for the comment! (I apologize in advance for the long reply). If you tried to charge it with a trickle charger and the volts are still the same (4-5Vdc) you could check for voltage across the batteries. They are running in series and each battery should be about 5Vdc. Using the volt meter, Put the Pos + probe on the Pos + end of the first battery, Then only move the Neg - probe across the batteries. As you move down, the voltage should increase by the 1st battery voltage ( if Battery 1 = 5Vdc, then battery 2 = 10Vdc, Battery 3 =15, etc.) If your first battery is only "Say" 1.5Vdc then your next should be 3.0, then 4.5 etc. This will help to rule out a Bad Cell. If one of the cells is reading the same as the one before it then either that cell is either bad or the solder at the end of the battery has came off. If there is a bad cell, it can be replaced at a store like "Batteries Plus" (They're one of the stores that come to mind). If it passes this, then, There could be an issue with the card or the firmware itself that was installed on the card. I hope the info helps. Let me know how it goes. Cheers! Shu
Make sure your charger is at least 12v, I initially used a 5v charger and experienced some of the issues you mentioned. I am sure that you have already resolved the issue as it’s been a couple of months since you posted.
Mine Ryobi Intelliport 18v, turns on, once I install the battery it blinks red all night. I come out the next day and the battery is still dead. I had this outfit since 2014.Help ,.. thank you.
I have a 12 V trickle charger for our utility vehicle. It has positive and negative alligator clips on the end. Is there any reason I couldn’t use that for this situation on the Ryobi battery?
Thank you for the question. (I apologize if the reply is a little long.) Common sense would say yes. But, unfortunately, Ryobi doesn't have much common sense when it comes to batteries. On these batteries, there are three metal tabs for charging. One is the positive, one negative and the third one is to power the firmware built into the batteries to work with the chargers. When the battery is plugged into the charger one will power the other and allow the charging circuit to close and allow charging through the metal tabs on top of the battery. That's where bypassing the circuit card the way I did allows it to be charged again from a charger. Most trickle chargers are like yours, 12V. but these batteries are 18V. I do believe the low voltage cutoff for the batteries is around 14Vdc. That's when the tool will stop working until the battery is recharged. Again, I apologize for this being so long. I just didn't want to say No without a reason. Hope this helps. Cheers! Shu
Good video. But the Charge doesn't last very long I done it with Craftman Ryobi milwaukee and Dewalt and is the same they run out of charge Quickly in less than 25minutes.Oh well Gooday folks bye-bye 😢😮😊
I wish it was only Ryobi. I'm working on trying to figure out some Ridged and Craftsman batteries too. They have their little differences on the circuit boards.
@@garydudley1379 I'm sorry to hear that you're experiencing issues with your battery. Have you had a chance to try using it since charging it? Sometimes, discharging and then trying again can help resolve charging issues. However, if it still doesn't charge, there might indeed be a problem with the circuit card that would require further investigation or professional assistance to fix.
@@LivingFree365 thanks , I’ll let discharge and see. Checked each cell and they seem ok so if doesn’t charge after discharging might have to toss it out.
my wont to be charged (dltc) drill 36v battery, i will try to charge the battery for 22 minutes with wires and 19v power supply (main power supply 21-48v) then i will see if will work, updated:: it doesn't work.
There are other ways like drilling small holes in the plastic housing, but if drilled too deep it could mess up the battery. Do you know of any other ways?
It is. A lot cheaper. And if it doesn't work for someone at least they're not wasting money buying a new battery when their old one could possibly be fixed.
Thank you for the question. I've only had to do this once to my batteries. (my oldest one I did this to is from 2019) From what I've noticed is that most of the batteries I've received were used and weren't recharged after use. Almost all of the new rechargeable batteries on the market now (all brands) actually have firmware installed in them that will prevent the battery from being recharged if the voltage drops too low. (Well below the low voltage limit that cuts off the tool). That's why in the video, the way I applied the charge, bypasses the circuit card and will allow the battery to accept enough of a charge for the charger to acknowledge that there's a battery ready for charging. Sorry for the long reply, but I hope it helps.
@LivingFree365 thank you for your reply. Heres my situation 2 18v batteries wont charge. 2 out of 4 lights are lit on bat. Put volt meter on bat. Resds 18.5volts
@@shonmcpike4013 Ahhhh, I see. Have you tested the output from the charger itself? That's why in the video my charger is a small one. I bought the wall plug single battery charger instead of the big one because the old one wasn't charging and that made a world of difference. If you have a neighbor that has a charger, plug your battery in theirs and see if it will charge all the way up. That way you can tell if it's the charger.
@LivingFree365 i appreciate your help but thats not it either. I have 2 chargers and 3 batteries only 1 battery will charge. This is all items less than 60 days from purchase. So i guess I'll have to go with the warranty option. Big pain in my bu.... im disappointed with this product. First time I've ever had a problem with ryobi products in over 30 years
snap in the battery and get the same results I have a Ry-obi battery and it charge full . put battery run my weed eater it will run 2 minutes and dies recharge use it again the same results . need to drain the battery how do I do that only have weed eater --------------------------------------------------------- Full-charged = 14.65 stop at 14.05 open battery tested at 15.13 pole at 14.65 Each-Cells read 5] [ 3.05 ] 4][ 3.01] 3][ 3.04] 2][ 3.00] 1][ 3.01]
So glad you turned it off before chopping off your foot. I'm not exactly sure why you would want to cause harm to yourself. There are doctors and specialists for those kinds of thoughts. Cheers!
Ha ha. I am also glad I didn't cut it off. It would've been informative to someone that dudnt know these tricks but I thought just to long winded and to long to get to the point. Your doing a great job teaching these people how to fix this kind if thing. Cheers man
Even DeWalt has the same issues. Most of DeWalts batteries are used for hand tools that will always receive a charge. The Ryobi batteries are being used more for lawn care equipment. That's the batteries that are having most of the issues. Most Rechargeable batteries have a cut out level that will stop the tool before the battery can deplete all the way, Ryobi batteries level is set too low in my opinion. So, Yes, Buying DeWalt will solve most of the issues.

If it passes this, then, There could be an issue with the card or the firmware itself that was installed on the card. I hope the info helps. Let me know how it goes. Cheers! Shu
Make sure your charger is at least 12v, I initially used a 5v charger and experienced some of the issues you mentioned. I am sure that you have already resolved the issue as it’s been a couple of months since you posted.
Sir. Thank you
Most welcome, Thank you for commenting!
Mine Ryobi Intelliport 18v, turns on, once I install the battery it blinks red all night. I come out the next day and the battery is still dead. I had this outfit since 2014.Help ,.. thank you.
You might want to try this technique. I had 2 batteries that did the same thing and now I've been using them for months.
I have a 12 V trickle charger for our utility vehicle. It has positive and negative alligator clips on the end. Is there any reason I couldn’t use that for this situation on the Ryobi battery?
Thank you for the question. (I apologize if the reply is a little long.) Common sense would say yes. But, unfortunately, Ryobi doesn't have much common sense when it comes to batteries. On these batteries, there are three metal tabs for charging. One is the positive, one negative and the third one is to power the firmware built into the batteries to work with the chargers. When the battery is plugged into the charger one will power the other and allow the charging circuit to close and allow charging through the metal tabs on top of the battery. That's where bypassing the circuit card the way I did allows it to be charged again from a charger. Most trickle chargers are like yours, 12V. but these batteries are 18V. I do believe the low voltage cutoff for the batteries is around 14Vdc. That's when the tool will stop working until the battery is recharged. Again, I apologize for this being so long. I just didn't want to say No without a reason. Hope this helps. Cheers! Shu
Good video. But the Charge doesn't last very long I done it with Craftman Ryobi milwaukee and Dewalt and is the same they run out of charge Quickly in less than 25minutes.Oh well Gooday folks bye-bye 😢😮😊
My charger old and new says my batteries are fully charged but none of the batteries work. Now what?
Is it only ryobi batteries that have this problem or is it all lithium batteries.
I wish it was only Ryobi. I'm working on trying to figure out some Ridged and Craftsman batteries too. They have their little differences on the circuit boards.
@@LivingFree365 I did bring the charge up on mine but the charger still won’t charge unfortunately so must be something else.
@@garydudley1379 I'm sorry to hear that you're experiencing issues with your battery. Have you had a chance to try using it since charging it? Sometimes, discharging and then trying again can help resolve charging issues. However, if it still doesn't charge, there might indeed be a problem with the circuit card that would require further investigation or professional assistance to fix.
@@LivingFree365 thanks , I’ll let discharge and see. Checked each cell and they seem ok so if doesn’t charge after discharging might have to toss it out.
my wont to be charged (dltc) drill 36v battery, i will try to charge the battery for 22 minutes with wires and 19v power supply (main power supply 21-48v) then i will see if will work, updated:: it doesn't work.
To much work but awsome tipa
Thank you, it is some work to do but, sometimes it's worth it if it works. 😁
you dont have to take the battery apart at all
There are other ways like drilling small holes in the plastic housing, but if drilled too deep it could mess up the battery. Do you know of any other ways?
trust ryobi to make it difficult. some of us havnt got a hope of doing all this. buggar it i have a 5ah flat no charge ,
Soon I will be making a video on how to bypass the circuit card on the 40V batteries to repair the batteries
Easiest way is to connect +to + and - to - on the batteries for 20 seconds no need to open up the battery.
How would you bypass the BMS circuit? The BMS won't allow power to be fed backward from the output terminals in the housing.
This method looks like its cheaper and easier to buy a new battery 🔋
It is. A lot cheaper. And if it doesn't work for someone at least they're not wasting money buying a new battery when their old one could possibly be fixed.
People tell me off for putting the screw in the adapters plug but how else am I gonna get the power out besides cutting wires LOL
You could use an adaptor plug and just connect two wires to it. Like this one. amzn.to/3QAieHG
@@LivingFree365 I have done that too in the past
How long before i have to do this again? Every time i charge it? This is is bullshit I'm done wivbth this product
Thank you for the question. I've only had to do this once to my batteries. (my oldest one I did this to is from 2019) From what I've noticed is that most of the batteries I've received were used and weren't recharged after use. Almost all of the new rechargeable batteries on the market now (all brands) actually have firmware installed in them that will prevent the battery from being recharged if the voltage drops too low. (Well below the low voltage limit that cuts off the tool). That's why in the video, the way I applied the charge, bypasses the circuit card and will allow the battery to accept enough of a charge for the charger to acknowledge that there's a battery ready for charging. Sorry for the long reply, but I hope it helps.
@LivingFree365 thank you for your reply. Heres my situation 2 18v batteries wont charge. 2 out of 4 lights are lit on bat. Put volt meter on bat. Resds 18.5volts
@@shonmcpike4013 Ahhhh, I see. Have you tested the output from the charger itself? That's why in the video my charger is a small one. I bought the wall plug single battery charger instead of the big one because the old one wasn't charging and that made a world of difference. If you have a neighbor that has a charger, plug your battery in theirs and see if it will charge all the way up. That way you can tell if it's the charger.
@LivingFree365 i appreciate your help but thats not it either. I have 2 chargers and 3 batteries only 1 battery will charge. This is all items less than 60 days from purchase. So i guess I'll have to go with the warranty option. Big pain in my bu.... im disappointed with this product. First time I've ever had a problem with ryobi products in over 30 years
YES but you should not have to
snap in the battery and get the same results
I have a Ry-obi battery and it charge full . put battery run my weed eater
it will run 2 minutes and dies recharge use it again the same results .
need to drain the battery how do I do that only have weed eater

What is a “baatree”? Is it an evergreen or deciduous tree?
“Litterly” is not a word.
It's my Southern accent. And yes You are correct, "Litterly" is not a word. Now, "Literally" is a word. 😀
I could not watch past the 4 minute mark. Long winded explanation i just wanted to chop my foot off but turned it off instead.
So glad you turned it off before chopping off your foot. I'm not exactly sure why you would want to cause harm to yourself. There are doctors and specialists for those kinds of thoughts. Cheers!
Ha ha. I am also glad I didn't cut it off.
It would've been informative to someone that dudnt know these tricks but I thought just to long winded and to long to get to the point.
Your doing a great job teaching these people how to fix this kind if thing.
Cheers man
A picture is worth a thousand words... let your doing do the talking 🤔
Easy solution to junky batteries., buy DeWalt problems solved.
Even DeWalt has the same issues. Most of DeWalts batteries are used for hand tools that will always receive a charge. The Ryobi batteries are being used more for lawn care equipment. That's the batteries that are having most of the issues. Most Rechargeable batteries have a cut out level that will stop the tool before the battery can deplete all the way, Ryobi batteries level is set too low in my opinion. So, Yes, Buying DeWalt will solve most of the issues.
Nice I have a 6 piece Ryobi set
I love my little screw gun and Ryobi radio.
