Hi I have 6 dewalt 36 volt batteries that have died. By that I mean there is something defective about them and they no longer will charge. Is there a way to check a cell to see which ones are bad. I would like to take apart the battery identify the bad cell or cells and replace it with good ones from another battery. Even if I only end up with 2 or 3 good batteries that would be fine for me. They run 160 a piece through lowes and home depot.
@73amxman Yeah you can remove the plastic and then use a volt meter to check which cells are under the -2.2 volt?- threshold and charge just those cells with ac adapter putting out roughly 4 volts and 400 milliamps. You just need to get the voltage up on the weak cells and then pop it on the charger again. I brought all my dead packs back this way. I dont let them sit around almost dead anymore top them off at the end of the workday.
Look, everything in life is at your own risk and discretion. Intelligence must be applied. It's also dangerous to invest your life savings in the stockmarket but people still do it....If you don't understand something then simply look it up.
This vid ain't that clear on where to place + - wires on battery heads. So I would say either put another vid up explaining or take this one down cos it's dangerous to mess around with polarities without being clear. Sparks.
I think it's ZnCl. I made it and it works perfect. Without it, you can heat the place by trying to solder but rezult is still zero. With that flux just need to touch with solder and it covers all the place with flux. Just like soldering copper.
cool got it. :D

Wow! That's very professional! Very well done! I don't think battery manufacturers will mind.

Not recommended to solder on the terminals. It overheats the internals on the cell.

Where do you get the shrink wrap for the finished pack?

what kind of battery bars are you using?

Oh so that's how those old phone batteries are made!

Is tinning just referring to heating and placing some solder where needed like as shown on the batteries ends and on the battery bars?
After the scotchbright, is that some flux he is rubbing on the top of the battery?
I also read to attach and tin on the edge of the battery tops so not to fry the batteries.
Any other soldering tips?

Are these battery cells made in China ?
Do you sell them ?

Google for 'A123 cells' or 'Li-ion' or 'LifePo4'.

Was that flux that was spread onto the battery terminals with the q-tip? Also, what was the wattage on the soldering iron used (butane/electric?)?
mikejbeiler 4 years ago
looks like an electric soldering iron
use the same iron u use for soldering normal nimhs or nicds but dont leave the iron on the cell for more than about 10 secs max
