THANK YOU! it worked like a charm! Instead of jumping on the charging stand, I jumped onto a charged battery and held the connection for 30 seconds. I then reassembled the dead battery and put it on the charging stand and the green light lit right up! Great video, very helpful - thanks.

This was a very good video. I love the trick about using the battery charger to charge the battery. So simple but something that most people would not think of trying.

Yours was the best of the Ryobi battery fix-it solution videos! Helped me repair two of them. Thank you!!!

I liked your instructional video and was preparing to begin the process when I decided to clean all of the contact points with a pencil eraser. Guess what! That did the trick.

Thank you, it worked again! The tip about using the own charger as a booster did it all.

outstanding work sir. I have several of these batteries sitting in my recycle bin I will now try this on. Kicking myself that I didn't think of trying something like this already..

I live in the Bahamas, my wife and i just came back from Florida, where we perches a weed wacker from home depot, now am about to cut the yard then this battery problem happens, thanks to your video, i was able to fix the battery, this video was straight to the point with minimum technical terminology and the use of simple tools, so while following your every move am saying (self do you know what you are doing ? nope, but am hoping to get lucky), And it work like a charm!

Needs the 3rd (and maybe 4th) prongs also hooked up, and I'm waiting on more leads, so I used another battery to jump. Worked good on two so far, I have them both charging.

I used a 3/32” drill bit to knock down the security pin in the Torix screws. Works well. My battery has longer screws thru the bottom rather than on top of the battery. The larger screws require a #12 torix bit while the smaller one is #10. It’s difficult to detach the top from the board because the wires are so short. It’s a model P103. But you should be able to charge by applying the leads to the battery packs following the same orientation as the video.

Perfect, THANK YOU! Only difference for me was it was at 3.05 volts. So the first couple of times I hit it, the green light didn't start blinking at all. Then after the third shot, it measured above 5 volts and the green light came on after that.

Thanks for the video! I managed to revive my battery which my charger showed full after 5 sec before this procedure.

Thank you! You saved my day! You have the best video out there for this fix!

I used an Android cell phone charger (the type which has a cord with micro or mini USB plug permanently attached to the charging block which plugs into the wall) . I cut the micro-usb plug off and stripped the wires (there are only 2, positive (red) and negative (white). In my case the batteries were all consistently low but none dead. I identified positive and negative ends of batteries and labeled them with marker. Then held wires on ends of each individual battery for 20 seconds each. That's all it took to raise the pack voltage enough for battery pack charger to charge normally. It's a good idea to check individual battery voltage after pack is on charger for a bit to see if any of the batteries are bad (voltage very low when others are high). If this is the case, bad battery cells need to be replaced and I wouldn't use it until it's repaired.

Worked like a charm. Thank you

It worked! Thank you for taking the time to show us this.

Hi. It's me again. I opened it back up to show what I did and it stopped working. I repeated the same procedure and the red light is on. it doesn't react at all when I put the positive, or the negative or the other clip on. Zero. Wondering if there is another power source I can use. I have one of those portable car battery chargers but the clips are very large

Thank you. Very helpful. Followed instructions and revived the dead battery.

Of course, that's the obvious solution. However these Torx Security bits are designed to stop idiots, and not people like you or me.

The third terminal on your battery is a thermistor. The is a safety so that the charge knows the temperature of the battery to prevent overheating/fires. Great video, I have done this to 3 batteries that would not charge. I used a car battery charger set in low trickle charge touching the contacts for about 10 seconds to get the voltage above the 8.3 VDC threshold.

My batery have charge indicator,but just turn on one led with 17 volts as if this One have a low charge,But my problem Is with the charger cause this one show as if the batery it's charged full And the problem is'nt in the charger cause It work with another batteries,i think that the problem could be with a electronic component Do you know Which can it be?

Is there a way to reset the control board. I have a battery that would not charge but had 20 volts across the battery pack. I slowly discharged it by running jumpers from the batt. pack to my drill. Then I charged it up with your process and still get the defective light.

I just use a drill bit slightly smaller then the inner diameter of the torx screw head and drilled the nub down. After that the screws come out easy with a regular torx bit screwdriver.

Drilling is a stupid way to solve it, plus the hardened metal will shatter the point of your drill bits. Simply lever the Torx pin sideways and SNAP IT OFF.

Thanks. I found one of these batteries in the recycle and one of the cells had corrosion on it so wouldn’t balance. Probably could harvest the other working cell but then again direct tools has these on sale for $20 all the time so probably not worth the effort of soldering in a new cell.

These are great fixes, but do we have to do this every time now when the battery goes dead?

What fo you think

The silver batteries never have a problem. The black ones are not that good. I had two go bad at the same time. Not happy with that.

You don't need a volt meter or a standalone power supply, and you don't need to know the voltage of the various cells before you jumper. You don't need any special tips on the ends of the I just pulled the top of the case (just the top) on my dead battery. TORAX security size 10 bits. I only had a standard TORAX 10 bit. I was able to get four of the five screws with a standard TORAX 10 bit despite the tittie in the middle. One I had to cut out with dremel tool using a dental bit. I used two random strands of wire I found under the sink to jumper pos/pos neg/neg to a good battery for 30 seconds. Pulling the top of the case allows you to bypass the circuit board, and send juice straight to the cells. After I juiced the cells for 30 seconds with the wires-I-found-under-the-sink jumper, I put the top of the case back on the bad battery, and threw it on the charger. Now the bad battery is accepting a charge. I'll put some of the TORAX screws back in if it goes to steady green on the charge indicator.

You idiot - there is no such thing as a _"TORAX"_ . To remove the security pin in TORX bolts, use a hardened screw like a self-drilling plaster or chipboard screw as a lever... insert to one side of the pin, and lever sideways to snap it off.

Big thanks, man. I'm not going to spend $80 for new battery.

although this way does work it will only work for a very short time. the problem is that the individual batteries that make up the pack are getting so low that they aren't capable of being picked up by the sense pin. to fix this CORRECTLY you must purchase a PROFESSIONAL battery charger like the IMAX B6AC v2 and charge each individual cell to full. I would not advise anyone doing any method other than the correct way as it could cause you severe injury or cost you your life.

@richardsaunders3082

3 жыл бұрын

SevenFortyOne ... it’s a series circuit made up of multiple cells, the welded connections do not matter, next time just try touching your probes to the bare ends of each cell, they are readily exposed, and “should” each show voltage of a 1.5-4 volts or a little more... that test will show a completely dead cell. Just because you have a reading above 14.5VDC for the whole series set of cells, it is not conclusive, it “could” be because one shorted cell, is combined with several overcharged cells, a dangerous condition. By checking each cell you know each is not dead and you can safely “bump” it back to where the charger recognizes it as “chargeable”.

Does this work with Dewalt, Mikita, Milwaukee etc?

Because the battery is so low the charger won't operate as a safety measure. You have to jump start the battery to get the voltage up high enough for the charger to turn on and actually charge the battery.
