Hope part of this video, will help in some way 😁

interesting points ,if anyone else is searching for reconditioning a battery try Jons Mender Guide (Have a quick look on google cant remember the place now ) ? Ive heard some interesting things about it and my friend got amazing results with it.

Hi Ein Felder Thank You very much! I do not have any DeWalt tools myself :-/ did ask my nabo,, but he had the old ones. Thank you for watching! :-)

I believe the charger is the BMS, there was wires for that.

The thin wires are most likely the balancing from the BMS,, they mostly measure voltages,, they do not need to be thick.

Yes if you have all new and better cells for it,, I would expect that to work.

I think you might have lost a connection,, batteries not in series anymore.

Hope you manage to fix them!

Likely, the best course would be to replace all the cells in the device to new. A bummer, but much cheaper than replacing the pack.

Thank You,, mine has broke,, again,, and I have not fixed it for quit a while now,, need to do that.

@@MyPlayHouse well i never got the one i made, with me home, though now i would love to have it.

Hi Christian Rosas Thank You very much! glad you liked the video :-) Thank you for watching! :-)

Sorry, I do not have the battery to look.

@@MyPlayHouse ok man thanks anyway

Good suggestions!

Try Ohm/Resistance ground and TH. Depending which type I think it’s something between 2k and 11k ohms

Th is the thermistor, the ID pin is just that, it tells the charger that this is a 2-5ah battery. This is because some of the xr range of cells can take different amounts of current. It's the reason why a 2ah battery charges in the roughly the same amount of time as a 5ah battery (charger depending)

Hi Dragan Thank You very much! glad you liked the video :-) Thank you for watching! :-)

Luckily the other old cells was old and beat up 🤕 with some luck, they can deliver the same now. But you are right.

It would be fine for a dewalt light or something but yeah in a drill it would become unbalanced after the first screw😅 good video though that first battery was really in bad shape

So what is your solution to a bad 20v Li battery

@@markhumannjr.5585 Replace all five / ten cells with new ones or find the same cells from a similar bad pack and cobble together one good pack. Note that Makita blows an electronic fuse somewhere when the pack goes bad, so you can't as easily repair those.

Sounds good. Somehow I've managed to ruin 6 of my 9 dewalt batteries so I'm hoping to get back 4 of them using the cells in The other 2.

In these batteries there are 18650 cells ,,, and they are widely available,, just search for them.

Well it´s safer than tasting :-)

Hope the video helped. :-)

Best of luck! hope it works out for you.

@@MyPlayHouse Nope it never but I really enjoyed trying to fix it lol

I got 2x R510s with 32GB of ram from a security company that wanted someone responsible to repurpose them (found them on marktplaats) here in the netherlands i paid 200 EUR for both, really good deal i think it's a good deal for your R710 specially if it's shipped, ram is cheap so. Make sure it's got all the bays drives and controllers though mine both had 12x 2TB SAS (24 drives total) and both power supplies only missing the rails.

@@dashtesla hey thanks i think so too, i will consider it for a nerd tinkering real server ar home :D

Yes the price is right! And like Dash says,, ask if they have the disk trays.

@@MyPlayHouse hey Morten, cool :D, yeah thats a good tip i will remember that

Humm I build that in 1993,, I think op amp .. but I do for sure not want to set any money 💰 on that!

That is a possibility, I could not see where the leds went to.

Apparently it is in the charger..

Ahh I only got a few lines down,, before it is just a new battery 🔋 in my book 📖.

Thank You,,Yes I have also had luck with that :-)

Hi Razvan-Cristian Marian Thank You very much! glad you liked the video :-) Thank you for watching! :-)

Yes,, they were non very good,, worked,, but not for long.

@@MyPlayHouse this tool comes in handy measuring internal resistance of those cells easier than using the 1ohm resistor SM8124A i ordered from Aliexpress m.aliexpress.com/item/33010929738.html?trace=wwwdetail2mobilesitedetail

Hi Tatăl Luptătorilor Ahh sorry I did not look.. Thank you for watching! :-)

sanyo ur18650fx generally @ 20a max discharge

Time,, this was 2 hours of messing around ;-) and I did not get to keep them,, and have no tools 🛠 that are DeWALT.

I do think the prices differences has gotten a bit smaller the last few years :-)

Hi Natur Erleben Time,, it's not worth the time really fixing a battery that is this fare gone,, If I was not filming it I would have just "retired" the first really bad battery :-) It can't really be trusted to last very long. Thank you for watching! :-)

@@MyPlayHouse Okay, I can understand that. I once looked, a new battery costs about 100 euros. That's why I thought you were doing something more :D

Usually a couple of cells will be dead. ( it happens on my LIPO too, ive notice) It's sort of a pain in the arss to resolder....I recycle , rebuild different packs for other usage....Mostly for Kiddie's toys, R/C, powerwheels...ect. I usually build 6s at 6600 mah...Try to keep all the good cell for best or good packs..I know I wont get 6600 mah out of them....but 1/2 hour of play time on powerwheels at 24V is plenty fun for the kids.... I have 6 packs...i can run 6 powerwheels all at the same times. i can take all my grand kids (3-ea) on a 2-3 mile drive or to the park. 1 hour drive time for each car.....I have multiple lithium r/c chargers. I can recharge all the batteries within 2-3 hours,,, Sometimes the kids drives there powerwheels 2-3 times p/day.lol The grand kids loves it..i get use powerwheels for only $50... Most of the time the acid batteries are missing...( I dont mind.lol) I have over 10 powerwheels....i rather save my lipo for my R/C.. Powerwheels 12V batteries are $60.lol The Lion Batteries are FREE...i got from the contractor working on our house. He has better things to do than to save Lion batteries....Im retired.lol It's hit and miss ...some pack...only 1 cell drop below 2.2... Other times..the diaphram has to be reset...They'll simply come back up to 3.6 once the connection is made again. other times 3-4 cells are dead. I usually try to recharge the cells...see which one will hold charge. i have couple of FAKE Imax chargers...they're STUPID,, It'll let me recharge at .3 volts.lmao My real Imax..is too damn smart to revive cells...hahaha Sometimes they'll charge back up..but lose charge ( So I just toss them out) I dont mix the C RATINGS or mah. You'll have to look up the part # on the cells... I also recycle laptops cells...they're only 10-15C..It's fine on the power wheels at 6s...not as fast as 30c......but it's still faster than 18V-20V. Definitely faster than 12V.lol My 5s 50c lipo has about the same power. Those batteries are expensive.

Hi Colin Devaux Thank You very much! yes,, or just put 1v over them :-) Thank you for watching! :-)

Hi Rafał Gadomski Thank You very much! Temperature nice :-) Thank you for watching! :-)

Hi plasmar1 Thank You very much! Yes,, that is indeed weird,, Thank you for watching! :-)

Hi Jim Catanzaro Thank You very much! glad you liked the video :-) Thank you for watching! :-)

Voltage not volatile!

Yes,, there is 5 cells of Li-ion 18650 inside and they go from about 3 - 4.2 volt,, so from 15 - 21volt the cells nominal voltages is 3,7volt and 5*3,7 is 18,5Volt witch is why we in EU buy a 18volt battery. The same battery in the US will say 20volt so that is probably what the battery shows fully charge.

No,, I was fixing these for someone else.

You get 2* 6.0AH on Amazon in the US for just $129,, that is about the prices we pay for one.

Well if you want to pay a lot more come here....

Hi David Smith I am not disagreeing with that,, it just became a bit of a challenge to try and fix it :-) Thank you for watching! :-)

Hi Kacper Thank You very much! glad you liked the video :-) Thank you for watching! :-)

Thank you very much.

I want tell, if you don't :-)

🤔

Hi Jr Rojas Thank You very much! glad you liked the video :-) Thank you for watching! :-)

Yes,, from 4 to 5Ah,, it is only the quality of the cells that change. There are 10 cells in there but 5 cells in series and 2 parallel. So a 4Ah has 2x2000mAh cells and 5Ah has 2x2500mAh.

@@MyPlayHouseOhhhhhh okay I understand now. Thank you so much!

Prices has gotten better,, you pay $73 for a DeWalt 18V 5Ah battery,, we pay $101 for the same.

@@MyPlayHouse It is expensive either way. :)

I look for clearance deals on different brands, 18-24 volt. I modded my rigid brushless drill to take any battery (which is flat without the neck). Packs mount with Velcro. I have 6 batteries, 18-24 volt and each battery cost less than $15. Some under $10. Just goes to show you how being locked into an ecosystem costs.

Hi kurbizza Thank You very much! glad you liked the video :-) Thank you for watching! :-)

They didn't die from old age or usage pattern. They were damaged from the rust shorting them. So why would the other cells all fail soon? Hmm?

Laughing all the way to the bank :-)

@@MyPlayHouse That`s what the guys at work say too but for every 2 or 3 tools they go thru i`m still using the same Dewalt tool. But often it`s the initial cost that has the final say.

It is not nothing,, but it is almost ½ prices.

@@MyPlayHouse I'll give you that point. =0) Still hurts the wallet.

Sorry I am on my phone 📱 STEVEN LONG IS STILL AWESOME 👏😁

From your comment, I am guessing that you are from the US,, and I would will agree with you,, that you should probably just get a new battery,, and you get good prices on replacement batteries in the US.

You completely missed the point of this video.

Keep in mind that the 18650 batts are offered with or without safety fuses the cost is the same for both so that leaves a little room for those that like to fiddle with things. The only draw back is that the Chinese cheapo ones sometimes pop the fuses but will work again if you remove the fuse.
