How To Fix A Cordless Drill Battery That Won't Charge

[@jorgesousadanielfreitas9349]

*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

[@alexdkk57]

mine sparked and smoked when i did it though, and i thought i would die, but i didnt die and it worked anyways! xD You know why it sparked and smoked tho? was it because the paperclips accidentally touched maybe? i mean it looked like on the battery indicator that half the battery was transfered to the other battery

[@zimsfedi8396]

Making use of the kzbin.infoUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type

[@DR-id6zf]

You, sir, are a genius. You just saved me $50 on my drill battery. I didn't have a second battery, so I used a 9V battery, connected it to my "dead" 12V for a few minutes. I was skeptical, as it didn't look like anything was happening. Put the old battery in the charger, and it's charging perfectly. Thank you! I'm canceling my order for a brand new drill, so I guess you saved me more than that.

[@marsonus]

Far out, both my Triton 18V batteries stopped charging over the last 2 days. Just tried this by wiring directly to the DC charger plug, bypassing the charging unit that attaches to the battery. The transformer had the pin polarity on the label which was handy. Left it to reach 18V, which took about 5 minutes each and plugged the charging unit in and it started charging. EXCELLENT TRICK and it actually works. My batteries are now charging. Love your work!!!

First, when I saw that video I thought it was a JOKE. A couple month ago I bought used DeWalt drill and impact drill from thrift store without batteries for $5.00 plus tax of course. And then I went to the local recycling place for something else and saw a full bucket of DeWalt batteries, I asked the workers if I can have a couple of them? they said help yourself for free. Then I brought those batteries home and of course, they are dead. Last Saturday I put them on the table to take them back but forgot to do that, lucky me. Tonight I saw your video and thought here is another scam, but let me try. And now I'm shocked! They work like new. Thanks BROTHER for your great video and your help to save my money cause now I have set of DeWalt for $5.00 (plus tax) . Thanks again.

[@rogergorrell1849]

Thanks for the tip. You explained the procedure directly & clearly without unnecessary waffle beforehand.

[@LikeaBigDog]

I have Hitachi cordless drill and 14.4v batteries. At 5 min it didn’t work, but when I tried again and left the “2 paper clip fix” on for 20 minutes, the battery charged right up! Thanks so much for sharing your knowledge, I really appreciate you and your willingness to help others!!!

[@ACountryWayOfLife]

I appreciate it. I am so glad it at least helped one person!

[@denniskang902]

THIS IS SOOOO AWESOME!!!! Thank you! Thought I had an unusable battery! Just a note of CAUTION: do this in a garage with nothing flammable around it. My paperclips started glowing red and smoking and I tilted them so they fell out. But it did work and my batter is now alive!!!

[@damianmorfin1506]

Bringing the dead back to life 🙌 this actually worked . I was setting up the paper clips on the batteries until a spark freaked me out . So i stopped messing with it , thinking It might catch on fire. So I set the battery on the charging dock for a few minutes . It started charging and now my batter works . I only placed the clips for no more than a spark (1 second)🙏 thank you !!!

On mine I got One spark ⚡️ I disconnected it and started charging right away

[@poppytzu5014]

Thank you so much !!!! I just did this and it worked like a champ as my dad would say. I have his drill and 2 battery packs but one didn't work. I was told that they went to another type and you just have to buy a new drill once the batteries are gone. Not sure about that but a new battery would cost me about $40 - $50. I think of my daddy every time I use this drill.

[@kathylopatowski8804]

Absolutely works!! Have a stack of dead batteries that have been sitting dead n my workshop for 4+ years and now they are accepting the charge after 5 min with the paper clip! Bess you for sharing!!

[@ACountryWayOfLife]

Outstanding

[@grkike]

Thank you so much! It worked for me! I did try to speed it up by adding a third paper clip and it caused a spark, so I decided to use two wires exactly as you mentioned and it worked like a charm. You r beyond awesome! Maybe in the future, you can explain a little bit more details such as will you always have to do this the same way etc. Thank you so very much!

[@Verglace]

Thanks for this, had a dead battery that wasn't used for 10 years. I didnt have an extra battery and couldn't find the same model for sale, so I used an AA battery, After around 5 minutes, put it in the charger and it started charging again!

[@noelfreedman289]

I just read the comments and I will "fix" mine. I've had this my Dewalt 9.6 batter tool for 16 years! First time one if the original two batteries failed to start; and will fit it tomorrow. Thanks for the tip! So I will now always stick to buying DEWALT tools!

Thanks so much I live in Australia and bought an Ozito everything combo pack and its 3 years old and 3 good batteries have stopped working over time plus I scored an ozito electric mower for free with 2 dead batteries thinking I have a few batteries at home try it .. lada dada dada.. anywho I tried this method as you showed us and omg I now have 5 revived batteries working perfect now for 1month plus the 2 batteries i already have and ive saved a fortune thanks to you mate.probably make some money back selling a few batteries now or getting a refund.. lol.. Im so happy and you just don't understand cause I was about to try take em back with no proof of purchase and now I dont have to at all.Just one less stress in my life. I want to let all Ozito users know that if your having Ozito Power Xchange battery problems push the led button on your battery and if it flashes on and off quickly and doesnt remain a stable on light for about 2 seconds then this method will work 100 percent. You are a champion.. Nick Australia

I tried this on my Dewalt battery, but no luck. I have one good battery and one bad. It might be time for a new drill. Thanks for the tip, I'll keep in mind on future batteries!

[@stuartsjalund6912]

It is simple: recharging any batteries requires about 20% higher voltage than stamped on the battery. For a 20 volt battery you are looking at least 24 volt to recharge. Add a amp meter to keep an eye on current draw with a suitable resistor added. One can always recharge at a 10% amp/hr stamped on the battery. Only when there is heat dissipated by the battery is any battery fully charged; the chemical reaction is stopped and excess power delivered into the battery is dumped as heat. Do not get stupid by forcing too much current through the battery, you could get surprised. For example a 500ma a/hr battery charged at 50ma requires about 12 hours to recharge; [do the arithmetic] ineffeciances are taken into account. The reason why OEM chargers do not work properly is the applied voltage is too low and LED indicator lights do not know when the battery is fully charged: only battery heat is the true indicator. Voltage measured DO NOT indicate a fully charged battery at full or greater than battery terminal voltage. All the above applies to any battery.

[@edwatson3582]

Are You Kidding Me!!! Ok, I am the truest sceptic out there....I thought for sure this was a click bait or some other video to kill some time. I watched it a few moments ago and went out to the garage to try on my 18v xrp battery that has been dead for over a year. As I'm fumbling with the paper clips I had a moment of clarity when I said to myself "Self, you cheap bugger. Just go and by a new one! Well I never had those paper clips on there for 1 or 2 minutes. I went to adjust them when I saw a little spark. I pulled the battery off the charger and into the drill...Holy crap It actually worked! So I will let it fully charge and find something else to buy!

[@davechapman631]

Wow..totally worked with a Bosch battery pack... you legend!

[@MathieuBosi]

Thank you, it worked like a charm! In my case I had just purchased this "TECCPO" drill with two 18V 2A batteries from Amazon. One of the batteries could be fully charged, but the other caused the charger to blink red / green, which meant "faulty" battery. So, I used the good / fully charged battery to "wake up" the faulty one (low charge, about 4V). I just kept the wires on for 15 seconds, since I've seen another similar video where it was suggested to charge by following cycles of that time interval (maybe 15 on, 15 off). After just a *single* cycle, the low charge battery was already at about 14V. And then the charger finally worked with that battery too. 🔋💪🏻🙏🏻

I tried everything to get my Dewalt battery to charge. I hooked it up to multiple trickle chargers that did not work. I put it in the Dewalt charger multiple times as recommended by other youtube videos. The only thing that worked was hooking it up to another battery. I do not know why the chargers will not charge a low battery. Even the trickle chargers from Cen Tech will not deliver a charge. Does anyone know why they design these chargers like this? Is it just to sell more batteries?

[@Tobinindustrial]

I think if a person didn't have another battery to boost the dead battery pack that they might be able to use a similar voltage dc adapter to pump some DC power into the dead battery pack. It should work as well as a good battery "paper clip" volt dump. Positive to positive and negative to negative as you suggested. Perhaps even a car battery would work as well to dump some volts into the dead battery pack. It would be interesting to see and I think it would work.

[@ACountryWayOfLife]

That is a great thought. I think you are correct as long as it doesn't burn the cells up.

[@Tobinindustrial]

@@ACountryWayOfLife As long as the wires aren't crossed it should be safe if you use the same DC voltage or less. I'd like to see it tested though just to be sure.

[@mentalcase4299]

Isn't the charger DC? It's basically the same principal, even if it's ac. So, obviously they purposely make them depreciate. Their charger bases are pointless for the most part, at this point. To me it seems like the charger should do the same as any other way.

[@terrencesauve]

@@mentalcase4299 there are IC protection and some logic embedded in any basic DC battery pack charger. Maybe the resistance across the cell pack is out of range or the DC voltage is too low? If it doesn't hold a charge after using this method, then some or many of the cells are shorted.

[@paulparrish4196]

Bear in mind your DC supply will have D C amps as well amps are heat therefore you must determine the amps of the dead battery and be sure not to use a supply that exceeds that number, like a car battery for instance.

[@terjeoseberg990]
