I called Ryobi and they were able to look up the date of manufacture by the S/N. If you lost the receipt or got it as a gift they will replace the battery as long as it's within 3 years of the manufacture date. Also, thanks for the info in this video. I had two batteries and didn't know which I bought when. It turns out the "bad" one is 5 years old. Your trick worked for me :)
@robertreightler9605 I am so glad you were able to fix your batteries.

"Can Power Ryobi"...or CPR for batteries. Other videos show them drilling into the battery, taking apart a 2nd charged battery, or other unnecessary things, but this was by far the easiest video to follow yet. And although my battery is less than month old (lost my receipt), I'm not paying for shipping to send it to Ryobi warranty to get it replaced. So thank you very much for this video!

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 !

Thanks! I had a different model Ryobi battery with a similar issue. I had to do some poking around to find the right contacts, but this process fixed the issue, and the battery now charges! Thanks!

You just affirmed a fix I've seen successfully performed on other videos. Don't be miffed, I always look for a fix for equipment repeated by others so that I'm sure of way to fix a problem. Thanks for your time.

This worked just as described. Thank you. I believe the problem we had was my wife was in the habit of leaving the battery in the charger and then unplugged the charger. This could cause it to drain the battery dead-dead-dead and here we are.

I knew these batteries could drop below a charge threshold, but was unsure how to kick start the darn thing so it would accept a charge cycle. Worked as described...Thanks Dave

Worked like a charm! I'm probably stating the obvious, but I think the yellow jumper bypassed the low-voltage chip on the BMS board thus allowing the batteries to take a charge.

Hi, merci Dave, j'ai suivi ta procédure pour une batterie compatible Ryobi de 18v 5A , la batterie charge de nouveau, avant mon chargeur indiquait que la batterie était HS. Pourvu que ça dure ! 😉

Listen Dave! You are a life saver, this worked as expected and it only cost me a little over $4 to buy the alligator wires. I wonder if this works for any other brand of battery?

FYI - if you have a RC battery charger, using it in NIMH mode in the same manner as the jumpered Ryobi charger will do the same thing, with slightly more predictable results. Just deliver a low (aka, 0.2a) charge for a couple minutes, any you should be good to go. Basically, you're just bypassing the Ryobi battery's built-in charge controller to get it out of "undercharged" status. Also, thanks for the tip. Resurrected my Ryobi battery from the dead.

Yes, this is a safer way to slow charge it up to a usable voltage since you can precisely control the current. I fix quite a few of my batteries from my RC hobbies this way, but definitely a good tip.

My friend has a Ryobi lawnmower and a string trimmer. One of her batteries stopped charging after a season of use. She threw it out before I saw this video. I imagine the batteries for that have similar circuits and can be fixed the same way.

Great video - thanks! Sigh Legaly Ryobi in the US should not be dis-honoring warranty because the plastic covers or any tamper proofing is disturbed/removed. BUT they deny anyways based on that.

You probably saved me about $200 in batteries if this works. All my Ryobi batteries died like this after not being not being charged for a long period of time. I figured the cells cant be bad that quick, and it makes perfect sense that this would work.
Mitoni, I have fixed several of my own batteries just like this it does void any warranty on the battery but if you forgot to register the warranty or the battery is older than three years this is a great way to put them back to work.

Thank you ,very helpful Mines charging to full but conks out in 20 miniates wheres it was going for up to 1 hour ,Its a line trimmer I may need another battery
@Deidre, I would always if possible have a backup battery for all my power tools. I have the 40v string trimmer and I have 2 batteries. Not sure what size the battery you have is but if possible for a 18v string trimmer you might want to consider using a 4 ah battery for longer run time.Thanks for taking the time to watch my video and comment if you haven't subscribed to my channel please consider that along with clicking the notification bell so you don't miss out on any future videos.

My 4ah battery was fully charged for a road trip. I left it sitting in the back of my truck and it rained which I wasn’t expecting. It is totally dead. Al I can think of is that the water must have shorted across the terminals. So my question is can you do this by contacting the terminals without disassembling it? Does doing it your way bypass a circuit board making this necessary? I know that’s probably a doofus question! Great video. Thanks
D, since your battery may possibly have some moisture inside the case I would take it apart to make sure before you try to fix it or charge it.

Hi Bernardo, here's how to test if the charger is working using a voltmeter. Touch the ground lead (the black lead) on the voltmeter to the negative (or ground) lead on the charger. The voltage output on the voltmeter should be the same as the voltage setting on the charger. If it is not, the charger is malfunctioning and must be replaced.

Just a note. No manufacture can void your warranty simply for opening the device. They have to show evidence that you broke the device by opening it. This has been law since the 70’s. Manufactures bank on you not knowing better. The law has been reaffirmed both in court and by the FTC.

Could not get this to work. Saw on the multimeter it only put out 1.5v for .5 sec. I used a 12v car battery. 5 sec on then 20 sec off for 3 cycles. 9.9v and was able to charge normally. Next time i would only do it twice. Thanks for the video. I had batt model p189.

What if you don’t have a spare battery to kick start one wich is not charging……can you use charger with leads to dead battery for that Ten second boosting charge
Hi Peter, Yes you do not need another battery just use the charger and leads.

Hi Kathy, I would still call Ryobi customer service at 1.800.525.2579 sometimes they will make an exception the first time and send you a replacement battery just give them the approximate date of purchase when asked that's what i did the first time it happened to me. They will even tell you to keep the old battery and then you can fix that one.

45 seconds use 12 volt car charger. Just hold negative to charge spot on stem and positive lead on base charging spot . Hold for 40 seconds green light on battery will flash you don’t need to take battery apart

I have 2 batteries that were in water for 5 days due to a flood. They don’t work as you can imagine. Is there any hope in a case like this or are they e-waste? I have several and I’m not sure if these are under warranty or not. I didn’t register so I’m on my own to either fix or toss.
Hi Jeanie, I would take the battery apart and make sure everything inside is dry and looks okay then test the battery fix if it doesn't work then you haven't lost anything but the time it took to try it. If the inside of the battery looks bad like the internal batteries have bulged I would just recycle them. Sorry for your loss in the flood.

For me, using a good working battery and putting positive leads and negative leads on the bad battery, helped to charge it just enough. For some reason it wouldn’t work with just using wires on charger to bad battery.
@TheJparral, I am glad you were able to get your battery charging again. I have seen several different methods to accomplish the same thing.

![RYOBI 18V Battery Not Working? [Easy DIY Charging Hack]](http://i.ytimg.com/vi/sqeiOkSNRsU/mqdefault.jpg)
I called Ryobi and they were able to look up the date of manufacture by the S/N. If you lost the receipt or got it as a gift they will replace the battery as long as it's within 3 years of the manufacture date. Also, thanks for the info in this video. I had two batteries and didn't know which I bought when. It turns out the "bad" one is 5 years old. Your trick worked for me :)
opposite experience here, they wouldn't help me unless I could provide a receipt.
I recovered 3 batteries using this method. Thank you

"Can Power Ryobi"...or CPR for batteries.
Other videos show them drilling into the battery, taking apart a 2nd charged battery, or other unnecessary things, but this was by far the easiest video to follow yet. And although my battery is less than month old (lost my receipt), I'm not paying for shipping to send it to Ryobi warranty to get it replaced. So thank you very much for this video!

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 !

Worked like a charm! I'm probably stating the obvious, but I think the yellow jumper bypassed the low-voltage chip on the BMS board thus allowing the batteries to take a charge.

Hi, merci Dave, j'ai suivi ta procédure pour une batterie compatible Ryobi de 18v 5A , la batterie charge de nouveau, avant mon chargeur indiquait que la batterie était HS. Pourvu que ça dure ! 😉

FYI - if you have a RC battery charger, using it in NIMH mode in the same manner as the jumpered Ryobi charger will do the same thing, with slightly more predictable results. Just deliver a low (aka, 0.2a) charge for a couple minutes, any you should be good to go.
Basically, you're just bypassing the Ryobi battery's built-in charge controller to get it out of "undercharged" status.
Also, thanks for the tip. Resurrected my Ryobi battery from the dead.

Yes, this is a safer way to slow charge it up to a usable voltage since you can precisely control the current. I fix quite a few of my batteries from my RC hobbies this way, but definitely a good tip.

My friend has a Ryobi lawnmower and a string trimmer. One of her batteries stopped charging after a season of use. She threw it out before I saw this video. I imagine the batteries for that have similar circuits and can be fixed the same way.
Hi Bill, not sure I haven't had a 40V battery go bad on me yet but always remember that Ryobi tools and batteries have a 3 year replacement warranty.

Legaly Ryobi in the US should not be dis-honoring warranty because the plastic covers or any tamper proofing is disturbed/removed. BUT they deny anyways based on that.

You probably saved me about $200 in batteries if this works. All my Ryobi batteries died like this after not being not being charged for a long period of time. I figured the cells cant be bad that quick, and it makes perfect sense that this would work.
Mitoni, I have fixed several of my own batteries just like this it does void any warranty on the battery but if you forgot to register the warranty or the battery is older than three years this is a great way to put them back to work.

@Deidre, I would always if possible have a backup battery for all my power
tools. I have the 40v string trimmer and I have 2 batteries. Not sure what size the battery you have is but if possible for a 18v string trimmer you might want to consider using a 4 ah battery for longer run time.Thanks for taking the time to watch my video and comment if you haven't subscribed to my channel please consider that along with clicking the notification bell so you don't miss out on any future videos.

When you put it on the charger, it starts out red, then goes to flashing green while charging. Solid green indicates fully charged.

i searched for this comment.
yeah solid red and green flashing then the battery is charging. only solid green is not charging.
Solid green means nothing if the battery is not working.
That wasn’t 5v it was 0.52v and after next two times you said it’s increasing but it actually gone down to 0.48v 🤷♂️
Thank you! I was able to save two out of three “dead” Ryobi batteries.

Thanks for the video! - But question: Once a battery dies this way, is that an indication that the battery itself is dying and will likely have the same problem again?

@@DavesShop I did! Definitely, it's my pleasure 🙏
My 4ah battery was fully charged for a road trip. I left it sitting in the back of my truck and it rained which I wasn’t expecting. It is totally dead. Al I can think of is that the water must have shorted across the terminals. So my question is can you do this by contacting the terminals without disassembling it? Does doing it your way bypass a circuit board making this necessary? I know that’s probably a doofus question! Great video. Thanks
D, since your battery may possibly have some moisture inside the case I would take it apart to make sure before you try to fix it or charge it.

Hi, my problem is that the charger does not turn on any of my three batteries. Any suggestion? Nice instructional video. Great job! Thank you
Hi Bernardo, here's how to test if the charger is working using a voltmeter. Touch the ground lead (the black lead) on the voltmeter to the negative (or ground) lead on the charger. The voltage output on the voltmeter should be the same as the voltage setting on the charger. If it is not, the charger is malfunctioning and must be replaced.

Just a note. No manufacture can void your warranty simply for opening the device. They have to show evidence that you broke the device by opening it. This has been law since the 70’s. Manufactures bank on you not knowing better. The law has been reaffirmed both in court and by the FTC.

Could not get this to work. Saw on the multimeter it only put out 1.5v for .5 sec. I used a 12v car battery. 5 sec on then 20 sec off for 3 cycles. 9.9v and was able to charge normally. Next time i would only do it twice. Thanks for the video. I had batt model p189.
James, glad that you were able to fix your battery.

Thanks you so much! My battery is still in Warranty, but I lost my receipt. I will follow your instruction and fix it by myself!
Hi Kathy, I would still call Ryobi customer service at 1.800.525.2579 sometimes they will make an exception the first time and send you a replacement battery just give them the approximate date of purchase when asked that's what i did the first time it happened to me. They will even tell you to keep the old battery and then you can fix that one.

You can also "bump charge"
Pretty much connect leads from one battery plugged into the charger to the dead battery it'll do the same thing

45 seconds use 12 volt car charger. Just hold negative to charge spot on stem and positive lead on base charging spot . Hold for 40 seconds green light on battery will flash you don’t need to take battery apart

You don't need to take it apart to fix it. Just connect 5v to contacts on the fully assembled battery for a few minutes then slap it on the charger.

I have 2 batteries that were in water for 5 days due to a flood. They don’t work as you can imagine. Is there any hope in a case like this or are they e-waste? I have several and I’m not sure if these are under warranty or not. I didn’t register so I’m on my own to either fix or toss.
Hi Jeanie, I would take the battery apart and make sure everything inside is dry and looks okay then test the battery fix if it doesn't work then you haven't lost anything but the time it took to try it. If the inside of the battery looks bad like the internal batteries have bulged I would just recycle them. Sorry for your loss in the flood.

For me, using a good working battery and putting positive leads and negative leads on the bad battery, helped to charge it just enough. For some reason it wouldn’t work with just using wires on charger to bad battery.
