Stuff I used in the video:
USB C lithium charging boards: amzn.to/3UkzNyN
USB C charging Boards: They run off a t4056 chip that charges lithium cells at 1amp. Some of the boards also have an output where you would power your device and it would shut off power when it got too low. You CAN'T use this function for power tools as they draw way too much and you will cook the board in 1 second. Wire it like I show in the video. There is no low voltage cutoff, so you will have to be smart and know when the tool is low on power. This will be your last sign to charge before you ruin the cells. Honestly you would have to be pretty oblivious to keep pushing it though.
Buy New batteries: If buying new, I would buy a single 21700 cell like the "Samsung 40T" . These are around $6 plus ship from various suppliers online. I wouldn't worry about using 2 18650 cells like I did as it is very tight.
Soldering on Lithium cells: I've done easily 500 cells now and never had a single issue. I have tried to damage them and haven't been able too. I mainly deal with Hi Discharge cells though that are rated to handle high heat. Steps: sand the cell top; soldering iron as hot as possible; rosin flux works fine but takes 2-3 seconds longer; Acid flux(plumbing flux) is super fast but wipe off surface after tinning; use rosin core solder to tin the contact and wire/nickel strip; Solder away. If it takes over 5 seconds to see solder melting/flowing, stop and check your setup.
After Thoughts about the Video: The great thing is Lithium doesn't care when you charge it..... What a fantastic little ratchet. I used it this afternoon on my 1952 Ferguson tractor to remove a starter switch and it was great. I'm happy with the $20 purchase combine with the $2 charging chip and free battery cells.

Those screwdrivers and the rechargeable lights were the go to father's day gift for the eighties andties and nineties
-
I have both of those in my garage, had them since new and yes they were birthday and father’s day presents decades ago, I run across them every once in a while and sigh and say I’ll get to it. I think i’ll dig them out tomorrow now that i’m retired. Thanks for the video, subbed.

I remember all that stuff.... I can't even express in words how excited I was to get a Makita 7.2 volt ni-cad cordless power drill..... Heh heh heh!!! Batteries slammed in the handle like the mags on a 1911..... Heh heh heh!!! Ohhh yeah.... That is a trip down memory lane right there... You're not wrong, all the cool guys had the charging base thing screwed into the wall of their garage....

There's a flashback. My Dad had both of those. When I bought my Husky 12V ratchet, I was expecting it to be waaaay better than the old B&D. Turns out, the battery is about the only technology that got better. It just lasts longer now. Not much more (noticeable) power. Great stuff, my friend!
-
Son of a. I literally tossed one of these the other day after it sitting in my toolbox dead for 5 years. Keep up the videos!
-
Seeing the Black and Decker screw driver triggered some great memories with my dad from the 80s/90s. Cool vid
-
Modern high drain 18650 and 26650 batteries have tons of practical applications.

Sweet, I am doing this ! I have a Craftsmen 3/8" ratchet like yours that my grandma gave me in the 80's. Much quieter than my air ratchet.
-
Talk about a trip down memory lane. My father had both of those and every weekend they'd come out for projects
-
Those were excellent cordless screwdrivers! I had one for many years i used everyday. I got rid of it many years ago when i moved, no longer using it, and battery was dead.
-
I have the B&D screwdriver and a 3/8in Skilwrench which is all metal body. Thanks for the video, I have been pondering replacing the dead batteries with new lithium cells.
-
Just an FYI. You can buy those TP4056 charging boards with protection circuits build in. They will prevent over discharging the battery. They are slightly more expensive and slightly larger.
-
I'm going to be searching for a power ratchet at estate sales & garage sales. Thanks Moe for the upload
-
I’ve got both and have actually kept them hoping I could eventually replace the batteries. This is a video I’m definitely keeping bookmarked 😁
-
I miss getting these old Christmas gifts!
-
I love the up grade !
-
Wow I had forgotten about the revolutionary power screwdriver we had when I was a kid. Well done on that retrofit!
-
Awesome! Thanks for covering doing this. I made a video, I think the Hypertough and Nextec battery comparison and noted I am planning to do the same or similar. Neat to see performed already. Thank you sir! Kind work!
-
Very cool. I remember my dad having those as I was a kid. I would use them to work on my bikes.
