I bought a drill still in the box from a guy off Facebook marketplace and as soon as i got home i started charging the battery. 2 hrs later, still blinking red. Contacted the guy about getting my money back and lets just say it didnt go well. To keep from burning his place down i decided to give this a try and it definitely works. Thanks Guy, you probably saved me from doing time. Lol!
Is there any specific wire to get to connect the battery to the computer charger? Or could I just cut the cord on the charger down to wire and use that? I’ve got several laptop battery/chargers that I don’t use anymore
amazing! this works. My tweak to the process was 2 dimes placed in the +/- terminals of the battery, hooked up a car batter charger set at 12v, 40 seconds of charge time. Worked like a champ!
Thank you. I've not used my heart power tools in almost a year. Was about to get so mad if all four batteries were just useless now. 😅 I appreciate the video man.
Thanks for this video. Started searching when I found that a replacement battery would cost $108. This seems somewhat risky, but worth a try. I have a ton of old laptop chargers, so here goes nothing! ...
@@danielmachado45 Saw that one too. I have a portable car jumpstarter so might try that. Stripped one of my laptop cables and it only had a white wire and a bunch of loose wires inside. No double shielded wires like yours, so didnt want to chance it even though I'm fairly certain the loose wires are probably the ground.
2 dimes and 4 amps on a 12v car battery charger for about 15 seconds and we are charging fine. Thanks for the video, and added tip from @Starsweeper-OG
Out of curiosity where do you stay where there's no wire available? It's an honest question, because even in prison there's wire available when there shouldn't be. Have a good day.
thanks i used a battery charger maintainer i had already with 2 razor blades in terminals and worked in less than 5 mins jump started and charging🎉🎉🎉🎉🎉🎉
@@RjBrown-ks5tz nope didnt get hot but only did for 5 mins and my battery maintainer is a 1A small one not the big one , but if you reduce , just after a few mins try and charge with original charger and hope works
Found a good fix to start them - put razor blades in the slots of the battery, take a nine volt battery, rest + to +, - to -, let sit about 1/2 hour and voila! battery now charges!
Yeah you should be able to, the gauge won’t really matter. If it’s a smaller size it might take longer to charge but nothing longer than 10 minutes is required
@@danielmachado45 Never tested it, after I charged it; just stuck it back in the Hart charger to see if it would continue to blink. I knew if I had to buy another Hart charger it would be more money, so I took it all back. I'm sticking with only Milwaukee tools.
@@danielmachado45 a dude gave me 4 brand new hart drills because the batteries weren’t working and I got home and fixed them all myself that’s how I found out about this
And do you know why that is it's because the motherboard cannot recognize the batteries after they have been discharged so much so what you doing is just jump started it so the charger will be able to pick it up

Just tried this, and it fixed the problem. Incredible. Thank you for posting this 👏🏼 🙏🏼
Thank you-I used a couple spare washers and the drip charger-great tip!

Absolutely works. Only waited about a minute before I transferred it over to the actual Hart charger and it worked perfectly!!

I have another video using a battery charger for cars, 12v trickle charger will work just look at my videos and you will find it

I didn't have extra wires. So i used Exacto blades. Charged it for 2 minutes and now it's charging like normal. Can't believe that worked!

Omg thank you so much. It really worked…. You gained a follower!! Love love love it ❤
You’re welcome, I’m glad I could help you out! Thank you

I'm using the 9v right now and it's getting very hot. Was that your experience?
@@RjBrown-ks5tz nope didnt get hot but only did for 5 mins and my battery maintainer is a 1A small one not the big one , but if you reduce , just after a few mins try and charge with original charger and hope works
@gogo12able I tried with the 9 v. Battery I could only hold it for maybe 30 sec. Before I got to hot. Also a 18650 cell got warm.
It worked. 2min is enough time to fix it.
It really worked thank you so much
Holy shot this really worked!!!!

Can you use razor blades instead of wire?
Can you go directly from the laptop charger to the battery? Is the red wire a different gage?
Yeah you should be able to, the gauge won’t really matter. If it’s a smaller size it might take longer to charge but nothing longer than 10 minutes is required
I try your trick with my two 20v batteries but it is still not working.
Now what should I do?
Thanks you!
why do you need the spare wire?
After jumping the battery brunging ut up to 95% it still didnt work on the Hart charger. STILL blinking. Is the Hart charger bad
I would say it’s the hart charger, does the battery work on the tool?

you just have to connect them for a few seconds and you can connect a good battery to the bad battery and get the Same result
Make a video of it

It's a joke that people have to do all this.

Yeah man
mines are the same. 😢
Could I charge a battery with another battery??
Thanks bro salute 🫡🫡🫡🫡🫡🫡
10 minutes was overkill.
My charger doesn't charge through the pos terminal
That’s odd.
@danielmachado5480 yeah the charger I have has a point at the neg. And 3 points in the center. The drill has the pos. The 3 center points and neg.
I have a 40V 2.5 ah battery will this work
So the charger needs to charged before putting battery in it?
Did you figure this out? Some how your comment slipped through the system
i lost my hart charger , can i use this as a charger aswell?
I wouldn’t. It’s not rated for the battery so it’ll most likely burn it out after a few charges. I’m not 100% sure, just playing it safe.
