How to Fix Ryobi Batteries, with Simple Tools - 1170

If Ryobi batteries are left for long discharged and cold,, they can become to discharge, and the charger does not want to recharge them. Many are then replaced, as this is defective.
Bu in this video I show just how easy it is to relive them,, with very simple tools.

I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.

Thank You all for watching and saving/releveling all your Ryobi batteries.


If you save/relive your battery. Please do let me know, that it worked, , and do share the videos with other people that has Ryobi Tools. So they know about this, before they spent money on replacement batteries.

Tried your 9v battery trick, result, can now recharge my battery, Thank you.

[jdaniels]

Fantastic! Made the process make sense and very feasible for any DIY person who can follow basic instructions!

[GavinBKN]

You are a genius!! Thank you so much for this video. You saved me over $100 in having to buy new batteries. I did exactly as you showed in the video and Shazam, batteries are charging again.

Thank you. I followed your instructions and used a good new Ryobi battery as my power source. Once l had power in the batteries it didn’t charge on the charger at first and the red light kept blinking. The battery felt hot so I put it in the freezer for a minute. Back on the charger now and charging fine! I am so glad I didn’t throw it out. Thank you so much for several fabulous videos.

Briiliant. Adopted the 9v battery "method". After 10 minutes I was able recharge the battery. Cheers

Thanks so much for fixing my battery and delivering it in person to Portugal!

Thank you Professor! Very instructional, practical and helpful.

I was just searching for reviving dead batteries, and this popped up!

I just discovered that I made the same exercis with an RB18L20 battery as you do in your video.
But I accidentally discovered a way to revive it without taking it apart.

At first you connect a DC source to plus and minus on the battery. A rubber band can be used for this.
As shown i the video, using wires with crocodile clips the Ryobi power supply can be used for this.

What I discovered was that when I wet my thumb and index finger and held them against the plus and the terminal between plus and minus the charging started.
I also tried to replace my fingers with a 150 kOhm resistor and that worked too.
I have not figured out if it is safe to replace the resistor with a short.

When I found this out the charging was well on its way, but I think it would be sufficient with just a few minutes to reach a sufficient battery voltage to proceed with the Ryobi charger.
It seems to me that these Ryobi batteries should shut down with more juice left in them.

By the way, many car battery chargers behave in the same way, they refuse to charge a dead battery.

Thank you for sharing your knowledge on how to fix these batteries.

Thank you sir - for this information-
I can't wait to try this on half a dozen batteries I have that will not take a charge. ... subscribed . I will let you know what happens. I've a small fortune in these dang ryobi batteries ( for my budget) and they've frustrated me greatly! I've found that they do not like cold-- like a unheated garage or even left in a car/truck . I hope that this works for me . I'm in the US/ Pennsylvania.... thanks very much in advance. I'm going to binge some of your past posts to learn more. Your teaching/explaining is top notch !

[geoffsnelling]

thank you just got first of 2 packs taking a charge, i used car battery charger as my power supply for about 30 mins to boost the ryobi pack

[stevelandells]

Great video on the repair of the Ryobi Battery - much appreciated :-)

[johncastellano]

Wow how many batteries I have I hope this works ty so much for this info. Going to check out all your videos

You should have checked each cell voltage, because they will most probably be out of balance. That happen to my ryobi batteries. They were not that low in total voltage, and could be charged with Ryobi charger, but when charged fully they held little charge. This was because couple of cells were lower voltage than others. E.g. some cells would be 4.15V and some 3.4V. So charger would stop when some cell reaches full voltage, and BMS would stop battery usage when one of the cell would reach low voltage.
So I used simple USB Li Ion magnetic charger and put it on each low voltage cell and charged them to the same voltage as rest of the cells. Google for "Olight UC" charger to get an idea which charger I am talking about. This makes it easy because it is simple to put charger on the single cell with magnets, without disassembling cells.
And this works for any batteries. This way I also fixed Parkside X-Team 20V batteries.

Thank you for your information I just did what you recommended and it works. Thank you god bless you.

[albion]

Thanks for your expertise. could I use a motorcycle 12v battery to recharge an 18V Ryobi battery like you did.

[billseewald]

Have a relatively new battery that quit working or charging /it was replaced under warranty/ question is the battery repairable? It blinks red and green at the same time when placed in the charger ? Is this any easy fix any help would be great thank you

[Silver_Surfer_]

Hi there. Good info indeed. Thanks. I got a couple of Ryobi batteries wet and now they won't charge 🤔. They seem incapacitated. I've had other brands that have gotten wet with no problems. Any idea what is going on sir? They are not that old.
