I did this on my daughters battery, but it was the bigger one. I tested each cell and discovered one totally bad cell. A cell that is flat will never come back. Good try . I give you credit. I generally find the same thing happens. The battery charges to a certain level, after another attempt, it actually loses voltage. At that point, it's a candidate for the recycle bin.

Dude. After you boost the bad battery. No batteries in the charger. Unplug the charger for 1 minute. Put the bad battery in the charger and plug in the charger. Voila !!!!

I'll have to give it a shot. I'm not sure why that would work but if it does, I'm all for free fixes!

The process worked like a charm for a Redlithium USB 3.0 battery off two D cell batteries, thanks for sharing

Right on!

Works on m18 too

@jeffjohnson5390 Ай бұрын

I had two m18 batteries that I jumped this way and brought them both back to life.

Awesome!

Worked on mine. Jumped a battery just like yours in the video with the same battery. I tried it a while back with 20v dewalt batteries, but it didn’t work

Bummer, at least you got one back!

@dennisbielov8604 2 ай бұрын

I just restored 2 of my m12 6.0 batteries this way. They were drained due to sitting long time (very long time) without use.

Glad it worked out for you!

Also if you keep just taking it off and back on the charger it will eventually charge up enough to take charge again. Ask me how I know

I’m all for free and easy fixes!

How long did it take u?

@michaelgoodwin5162 9 ай бұрын

A better-quality charger COULD help. I had this scenario with a 12v DeWalt.

@learnsavediy 9 ай бұрын

I'm not following. How is an OEM battery charger not quality? Or are you just saying in general a generic charger is not as good as a OEM one?

@michaelgoodwin5162 9 ай бұрын

The more expensive and or rapid chargers often have better electronics. Some of the guys I buy tools from can't give those M12 chargers away. I have a couple I've never used. So the experience I had with DeWalt was a 12 volt 1.5 AH battery that came in a kit. The cheap kit charger would not charge it due to heat. I tried it in DeWalt's 4 bay fan cooled rapid charger. No problem.

I'd trickle charge it using a car charger for couple of hours 2 amp or something outside. Just for shits and giggles, I wouldn't be defeated that easily bud. 😊

Thanks for the tip!

@bombing626 7 ай бұрын

I’m pretty sure you’re supposed to leave it jumped for way longer than a minute

@learnsavediy 7 ай бұрын

@4:20 I mention I let it sit for up to 30 minutes and still no change. I’ve done this many other times with other batteries and if the cells are good it does in fact takes less than 1 minute to jump the battery.

@neeko7878 Жыл бұрын

The only thing about jumping the battery is you need to do it every time pretty much

@learnsavediy 11 ай бұрын

It depends. It’s just about getting it above that nominal voltage so the charger recognizes it. If the cells are good, just discharged, you should only need to do it once unless you let it keep dying. If the cells are bad, then yes. I’ve done this to other batteries that just were sitting for years and now charge on their own in the charger after only jumping it once.

Or in our case we left it sit dead for a month

Not worth the risk with the 12volts, buy a knock off waitly for $10 they work almost perfectly out of 12 I had one bad. Fuck Milwaukee and their $200I batteries that last 4 years with 15 charges only on them. I done this hack with big paper clips for the M18s and I had luck both times BUT the paper clips got instantly HOT in 3-4 seconds. I could see a fire coming if I waited any longer , I immediately disconnected them burning my fingers. But fixed both my m18s. You put fire and burn on the line. Wear gloves,do it outside and use 14 gauge Rolex wires with goggles if your a gambler. If no luck but the knock offs m18 never had a problem with them. For every 4 year old Milwaukee that bad with 15 charges on them I don’t reward Milwaukee I reward their competitors

Well.. Your basically more right than wrong in thinking something like this might be possible.... By correctly assuming that one unchargable battery could be "jump started" or brought back to life by connecting it in paralellwith a fully charged battery...But you have to account for the fact that each battery is a package of several battery cells... which is 3 in this case.... If you apply your method at that level it will most likely put enough charge into the "drained" battery cell so that a regular charger could finish the job as usual.....Also the voltage in each battery cell must be in equalibrium aka balanced....If you do that , put it back into the original pack it should all be fine and dandy...More or less!..;-)
