Never knew rebuild and replace are synonymous when it comes to batteries.

[@SaulRmz9310]

Great video!

[@pauldavis4285]

Where can I buy the 3M paper?

[@derekmendel417]

One of the few well done videos on you tube. One thing though. What should the voltage be on one cell

[@knight3131]

What is the make and molder of the spot welder in your video ?

[@yoberdob]

Just picked up a spot welder. Hope to be able to help some friends out. Where is a good supply for replacement cells and the flat metal leads? Thanks, Wes

[@alexandres8846]

To balance nimh battery packs, a circuit with two 1n4007 diodes in series plus a resistance of 1 to 10 ohms is used.The voltage drop in each diode is 0.7 volt x 2 is 1.4 volts.The resistance limits the intensity of the balancing current. Being soldered to all nimh cells this increases the life and performance of the battery pack.

[@scottcook414]

Sounds like a ton of work, should probably just upgrade your tools.

[@alexandres8846]

@@scottcook414 easy versión by balancing the cells with resistors in each of a value between 430 ohm to 1k ohm. this applied to battery packs on old satellites google patent information.

[@esmilner3]

Why do this? Answers: This is more fun. Because we can. And looking below, some people don't have reliable access to battery pack replacement or even new tools. I think the DIY is fun, to a point. I don't have a welder or sottering gun, so I don't see myself doing this regardless, but I ahave a recently dead Dewalt 18volt NiCad battery pack and I don'twant to buy new ones. I'll try to jump it, not rebuild, but still, I get it.

@@scottcook414 Yeh! That's the idea, every time a Mfg wants more money make something perfectly good seem obsolete, & people will just blindly follow ! BTW, you can make with better cells than original !

[@WagonLoads]

NEVER EVER turn a screw forward when putting it back into a hole.. I turn it backward very slowly until I hear and feel it drop into the original thread groove. Then Just as it fully drops into an original thread groove, I turn it forward and feel if it has any binding resistance. If it does, I turn it backwards again until I hear/feel one more click.. Then I turn it forward and feel if it is following the correct groove.. And always put the same screw into the same hole.. This insures that the threads don't get stripped...

[@tech0you885]

Everytime he was soldering, you can see the screw holding the solder sparkle...

Where do you get the recargable battery

[@charlesreed1207]

Where do you get the 3M covers?

[@Dino-987.2]

Where do you buy the 3M cover?

[@vilsonpinto7718]

What type of battery did you use to replace the old ones?

[@ricksmith2476]

Fantastic job how much do you charge to rebuild battery like u to rebuild 4 batteries

[@williamssandoval30]

De cuanto es el termisor?

[@ek8710]

Do the individual cells need balancing before making the battery?

[@williammatsko1158]

What name brand is your spot welder an where to purchase. Thank you

[@vilsonpinto7718]

You said to recycle ♻️, ok. But would you be able to test each individual battery to see which one of them are really dead? Sometimes we have only one dead battery!

[@ronschreiber3635]

Nice if you have the welder.

[@kenibnanak5554]

What brand and model of welder is that?

[@glennwood7149]

Do you rebuild Lincoln 14.4 batteries

[@davidburgess9002]

I'm not able to find the batteries here in the Philippines.

[@thomasgiannis5261]

Hi,where are you located?

[@poti2875]

what do you call that adhesive pad? it looks like it is made to fit that dewalt battery?

[@powertoolexpert6999]

I’m wondering the same thing

[@LBZOverlander]

GCbattery has them or you could make your own.

[@konagolden3397]

It's just paper. Buy some card stock and use a scissor.

[@derekmendel417]

Where can you purchase the NiCad batteries at. What voltage are they and what amps

[@konagolden3397]

Amazon

[@jordyrobignon3387]

why not rebuild it to li ion?

[@nonothing1115]

Hi does anyone know where I can purchase the batteries and 3M insulation pads. Thanks in advance.

[@scottcook414]

No BMS?

[@wildbill6976]

nicad doesn't need bms

[@MrStevos]

Can I Borrow your spot welder ? ☺

[@kurtism9040]

A little fast with respect to the "spacer"? but overall nice explanation. Some blocked shots too... maybe a tad bit slower would allow for better camera shots. Thanks for the video.

[@vilsonpinto7718]

Which battery 🔋 did he uses?

[@generovinsky7228]

screw that ill just get a new battery

[@flyerh]

Why, when non branded new battery packs are so cheap?

[@ceeweedsl]

Because they use cheaper cells that are rejects and have lower capacity?

[@scottcook414]

@@ceeweedsl correct, they suck.

[@powertoolexpert6999]

The cheap batteries do NOT last

[@powertoolexpert6999]

The new cell are stronger than new aftermarket packs

[@wildbill6976]

the generic chinese batteries are complete garbage; low mah, and don't hold charge; never had one last more than 4 or 5 months

[@steve8450]

lotta work to rebuild these packs...geesh..i thought u could just remove a few screws, take the case apart, desolder old bats, solder in new ones might as well just buy em new already made for $50 lol, dont have a spot welder, just soldering iron...sighh...wanted to buy high end r/c car batteries as I'm into that hobby, and use them in a pack for my drill..my research tells me theyre the same batts in size/type etc

[@powertoolexpert6999]

Aftermarket packs don’t last

[@powertoolexpert6999]

New cells will outlast new packs

[@fromsoftart3505]

Hi if I send you 3 18 V DeWalt batteries de 9503 2.6ah little you repair them and how much it will cost me thank you. if you want my email. Thank you
