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 :)

[@joshlobel7949]

Brilliant! Worked for me with battery not charged for several years. 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 !

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!

[@DavesShop]

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.

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.

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.

[@DavesShop]

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.

[@AndrewHoehnMoscow]

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.

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

[@DavesShop]

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.

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

[@DavesShop]

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 sir, can you not to use the unmarked terminal to see if it works? Basically you want to charge the internal battery (by bypassing the internal circuit), but it does not make sense to use terminals beyond positive and negative in DC field. It should work if you simply connect positive and negative terminals. Thanks
