You have a natural way, of explaining. one of the best explanatory video's I have seen. your like Donny the lawnmower doctor. well done, I tip my hat to you.

Thank you for this. From my late father who was a carpenter, I inherited a DeWalt cordless drill that has a defective battery pack. Now I know how to repair it.

If have quite a few various brand cordless power tools from my late father which I have been cleaning up and checking them out during this lockdown period. I have loads of different Nicd and Nimh batteries all mostly working very/extremely well but a couple that need some attention. This video is very helpful to me. Thank you!

Thanks for the information as I have 3 packs that need repairs. I can probably sacrifice one battery pack to get the other two back working again and then see about either making a pack with new batteries. Great ideas.

HI that was very good .It has repaired 3 of my battery pack,s. for £10. Thanks David.

Excellent video. Great job. Will do this as well once I experience this symptom. Thanks!

Loving your videos - they inspired me many times.

great job. never thought about changing the batteries. thanks

Just like a pro. I'd never know you did work inside that battery pack. Nice!

You check the voltage of the damaged battery while it is connected to the other, miracle.

Hello there. How do I measure the capacity of each of these batteries? I think it's done with a charge discharge. What is your method?

I've tried this quite a few times. It's OK if you're super desperate and live out in the middle of nowhere. I always end up buying new replacement packs on eBay for around $15. Buying a sub-C size battery with welded solder tabs hasn't been good for me because the pack cells always seem to be just slightly smaller and there's no spare room, so you need another failed pack to pull from. I've tried this method with 18650 laptop battery packs, too, and it's just not worth the effort (lots of delicate charging circuitry in laptop packs). I've had some luck scavenging from the battery recycle bin at the Lowe's store and also pulling high-quality solder-tab 18650's from old laptop packs (peel off the tabs, file the weld points). You might also try just going around the faulty cell with wire -- you'll only lose a fraction of the total capacity, and a good charger should be designed to accommodate the change. Just check pack and charger for overheating while charging.

Where to buy nimh cells?

My B&D cost me $8 for new cells, plus the satisfaction of not paying $24 for a new pack.

Are those c cells or sub c cells? If the battery is leaking it needs to be replaced. It can NOT rejuvenated. Also look fro bulged batteries. these are also bad batteries and may explode if you keep trying to charge them.

individual cells from your non- working full set of batteries and from non-working individual multi cell batteries................. What strikes me strongly here is that professional battery restoring or exchanging batteries never use a soldering or pencil iron to connect the batteries. They have a Quickflash soldering device which heats up VERY rapidly but doesn't touch the batteries long enough to destroy the individual cells as do the high heat soldering irons and guns which would linger too long on the soldering connection and to get high. This heat generally destroys the new cell .The only answer is to do as the battery stores do and use a flash soldering gun. The temperature is high enough to perform good soldering but doesn't last long enough to destroy the cell itself. I have seen people buy the brand new cells and the heat destroys any cells that are exposed to the pencil's soldering iron's gun's heat whenever soldering is used. The cell becomes ruined due to the temperature. I'd be very wary of somebody who attempts to join these types of cells by a conventional soldering iron or soldering gun. You are likely to destroy the new cell However the SOLDERING would work great and is easy if you have the calibrated exacting flash soldering electronic device that the stores have.AND THE BATTERIES ARE NEW! Using a pencil solderer, Its heat is very high and can solder well .But the length of time the heat is used to melt the solder, the greater risk there is to destroy the battery cell.

It's the thermistor temperature sensor. It switches off the charger when the cells start getting warm - ie when fully charged and are dissipating charge current as heat. It's safe to use this method only with NiCad cells

You can also invert the defective cells in the pack if you don't have a replacement... it will result in a less voltage pack but still works...

The nominal voltage of each of this cells is 1.2V, but the máx. Voltage is 1.5V (he says 1.4V), you múltiplo it by the amount of cells in the battery pack (I think there were 15), and since they are connected in serial you get a reading of 21V

without spot welder it is dangerous to try to solder old battery. with overheat it can explode and its life is shortened anyway. good try though.

The Heat of a soldering gun or iron may very well destroy the batteries. Professional battery replacement establishments use of very rapid flash welding in order not to injure the batteries. I would not risk using the method you described.

@boblewis5558

No matter which, the process works for both. NiMH are better however, just don't ever replace NiCd cells with NiMH cells unless changing ALL of them at once, they do not charge properly otherwise. If you have TWO NiCd batteries and BOTH are sort of charging but not fully, replace ALL the NiCd cells in ONE battery with NiMH and hopefully find enough GOOD cells in total to make another good battery of NiCd cells. I have done this several times on all sorts of drills with pretty good success. Even if you are one or two NiCd cells short you can just buy a few new ones. I have even converted old 12v NiCd batteries to 18V NiMH batteries (of the same case type) with great success. There is a great video on KZread of a guy (Russian I think) who does a superb job of replacing NiCd cells with Lipo cells in a Bosh drill, including power check meter built in! That's MY next project. Do a search for it.

Do not waste your time & energy. It is much better to buy new one.

Sometimes repairing something is replacing the part that doesn't work. If your vacuum cleaner belt breaks, you still call it a repair when you replace the broken belt with a new one. You don't actually have to repair the broken belt to call it a repair

My fix is I don't buy anything with these batteries, only lithium ion they have run multiple years without trouble.
