In this video I will show you a really fast and easy way to fix and revive most dead portable tool batteries like how to Fix Drill Batteries that Wont Charge. Hopefully you enjoy today’s practical inventions.
Yeah, I have done something similar. I took a Ryobi battery apart and then used a lab power supply to charge the cells until they had enough voltage so that the charger would recognize them. Then I fully charged the battery and even tested it to have 70% of its rated capacity. But after letting it sit charged for a few days, it was dead again. Repeated with same result. Likely there was too much cell degradation leading to the self-discharge rate to be very high.
Very clever 👍🏻, tfs Julie 🇬🇧
Okay, so almost everybody in the comments is talking about how great this is but has anybody commenting actually done this with success?
Thank you
Wow. How long do you leave the two batteries connected to each other?
You can do this also with Nimh batteries as well. I've done this to extend the useful life of some of my batteries. I think as long as they haven't been sitting around for a year like that, then they can still be useful.
When the voltage drops too low on a battery it won't charge because it's becoming unstable it's a safety mechanism doing this might get you by if it was a matter of the battery just sitting too long without a charge this will probably work but if it's really old it could become volatile if you do this. Definitely charge it in the middle of your garage lol. If you plan on storing your battery for long periods of time you should discharge it down to a certain level you might want to get a professional charger to start the charge on them as well because then you can keep them in really good shape and they will always work
Very creative🥰🥰
Yikes. Be VERY careful connecting two batteries like that... there could be enormous current flow between one that's charged and one that isn't. If you're lucky the battery has an internal thermal cutout that will stop you seeing your house on fire. Really if you insist on trying this, at least use a bench power supply instead so you can gently bring the pack up to a safe voltage for charging...
thanks
Your New Invention Is Really Amazing and Wonderful❤❤❤️🔥❤️🔥💖👌👌👌
Awesome 😚 Hello Inventor101 Believe me, I like your video very much, I support you a lot 😍
This is dangerous on several levels. Never do this.
great
Nice❤❤❤❤
Genial 👍🏻
Valos had it right, this video is just click bait B.S. you can't fix a dead battery. This is just a temp bandaid that doesn't really work
Certainly don't understand why this works....but I'll give it a try!
Interesting.. I only just found the 20/40 battery for all my aldi power tools today.. very hard to find.. soooooooo I was already wondering... is it possible to rig up a way to supply power to the cordless range via mains ??
Even easier if you have one of the old 18v chargers is buy the cheap Amazon 20v to 18v adapters and put it in the 18v charger for like 3 minutes. The old 18v charger doesn't care how low the voltage is and will bring it back up to the voltage needed to use the correct charger.
