วีดีโอ

I am still stunned that this worked and so thankful for finding your video. Thank you so much for making this video. I was so frustrated with trying to get my old battery charged and I stumbled upon your solution and just had to try it. Now I wish I had not recycled my old Arlo batteries that were in the same condition.

Worked for me!

It works!!! Once again the University of TH-cam doesn’t disappoint, thank you!!!!!!!

Sir! Thank you! 🙏🏿

I am having trouble prying, the battery itself apart to get the white cap off the back so I can get started. It would’ve been a nice to show how you got in there. I’m trying to stick a screwdriver a small one in the crack to prior apart and it’s still not working. Any suggestions?

Excellent video, I knew about the +/+ -//- jumping but never had the "right" connecting wire to connect the battery. RAZOR BLADES I GOT!!! just unboxed a brand new 4AH/20 Volt battery. Two razor blades and a charged 20 v battery and the DOA is now charging normally. Thanks

Your camera is off most of the video. can't see most of what you are doing

THANK YOU SO MUCH I just replaced my cilinoid and i forgot my clutch was deactivate

Cool hope this works on my 131. Will save me a trip to town. Thanks 👍

Blades in the battery and leads to the blades, where does the other end of the leads go ? Apologies as I didn’t catch it specifically in the video

In a similar manner, I have a Snapple 58v battery for my hedge trimmer that is not charging. Can I use the same technique using cables plus-plus and minus to minus to get a significant enough charge to put back in its charger continuing to charge fully? I don't have another 58v battery of its type, but am wondering if I can use one of my DeWalt 20v dc power drill charger wired the same way even though one is a 58v and the other 20v? Perhaps the DeWalt can charge it's 20v up to 20v in the 58v battery?

Yes honestly was skeptical,two questions why does it work and does it work for long?

Wow! That is a design flaw from Dewalt. An average user wouldn’t know other than just return the product. No wonder many complaints from buyers that they are getting used batteries.

This worked like a charm thank you sir

Thank you so much for writing this. I had a Stihl chainsaw that I hadn't used in a couple years. Pull the starter once and it tried to start and then it locked up. I watched your video and luckily the problem was easily observed. The nylon crank pulley separated! THANK YOU!

I was just about to buy a new charger thinking it must have been faulty, when i came across this video. The trick saved me a lot of time and money, I am thankful. It works!

Thank you. It just saved me a lot of money.

I'm so happy I find this video I already changed the solenoid

Ji

I tried it on two of my flex volt batteries with no luck. One shows nothing on the charger and the other shows solid like full charge

Great! I was looking for this video

You let them soak over night. Takes the scrubbing out of it

Mine charges but wont go beyond 15% charge. Its been connected to the charger over night.

I saw someone using pennies

Big problem on these was the anti vibe mount rubs a hole in the fuel tank

What? This doesnt make sense to me. I have this same issue, i have no idea why yours tightens but no matter how much torque i use snd my torque drill ot still stays loose.

Wuaooo 👍👍👍

My pull rope is not pulling, remove the spark plug and everything moves freely. The spark plug looks fine, what's next?

It didn't work for me tried 12v 2a 12v12a 12v 50a no spark nothing tried on 3 batteries no luck

Top drawer my man. Thank you so much from 🇮🇪

My Arlo xl has three batteries that aren't in the block and I'm wondering if I can use a battery maintainer to get it going.

This worked for me too! I used a jump pack, 12.8v. It sparked on the first touch, not so much on touch 2 & 3, but now it's charging! Thanks!

Does anyone know if the shaft is supposed to engage when you're pull starting the engine? I have a Husqvarna 128ld that I put back together and when I rotate the engine by hand, the shaft acts like it isn't engaged with the engine. I inspected the clutch and didn't notice any damage.

Thanks a lot for sharing this information. Had a Dewalt battery fail on second charge. Jumped it with a 12v motorcycle battery as you showed. Sparked and is now charing on charger. Excellent! Thanks again!!

This worked for me…THANK YOU! 8 month old battery barely used. I suspect it does not like being completely drained, mine was powering the Dewalt inflator airing up an extremely low set of tires. Died while trying to air up the last one. I used my Schumacher battery charger set to 40a, just gave it a quick tap to get a tiny spark. Charging fine now.

I’ll try that today thank you

It worked great for me I use the battery charger/Maintenance with prong or the circle things and place them in the same locations as you and voila it work once I place it on the dewalt charger.

I have a 2011 and it does the same thing. It will smoke for a few minutes and it stops. Does it all over again the next time I cut the lawn. I've just been to lazy to do what you just did. lol. Mine only leaks when it sits for a while. Mine is garage kept. No rust. Thanks for sharing.

Why am i envisioning some dumb schiff liberals trying to jam 2 screws into their Tesla chargers!!?

Awesome. Saved my bacon. My chain tightener came out of the track. On a Sunday with a pile of work to do. The rope trick worked. Thanks for the advice waiting for it to get to the top. Close to the top worked for me. I have a 353. So have a couple other pieces. One thing I did have to muck with was lining things up putting it back together.particularly bad and chain.

Worked for me. Used a 12v car battery charger and sparked it a few times. Fyi ...initially I tried it at 2 volts but it didn't work. Wonder what the science behind this is?

That's great but you didn't make clear what the leads are connected to. Are they connected to a battery charger? Edit: Saw a comment about using a 9v to do the same thing so I tried it, holy crap, it work, just canceled my charger order. Thank you Thank you Thank you Disgusting of Dewalt to have not handled this, I've thrown out tons of batteries and even bought another charger in the past. This is the kind of crap that causes me to not feel sympathy for corporations when I hear of people stealing from them.

Hi, could you tell me what tool you’re using to fix the problem, the size etc.

Yup this work for me and I’m telling everyone of my friends about this !!

Thank you! I used one of those small, portable jumpstart battery packs and although I didn't hear it "spark" I got my Arlo batteries revived after a few rounds of 20-30 seconds!

What are the jumper cables hooked up to?????

I had 5 batteries that would not charge and there was no light on the charger. I tried it and it worked perfectly, thank you

It does work with other DeWalt batteries. I literally just jumped a DBC203 using another DBC203 and spare wire I had laying around

Great video! You solve my problem Wish I had seen your video first!!!

I tried this with a battery on 2 bars out of 3. Didn't work. Think my charger is junk
