@in_sympathy that is what I was currently looking at was purchasing a battery spot welder.

These batteries are tough to find with the tabs already installed.

I thought if I could buy the batteries and tabs separately then maybe I could purchase a battery welder to weld them on.

Looking on Amazon it looks like I could get a battery welder for less than $100. At the same time I know very little about all this stuff and while I'm not opposed to learning I hope I'm not getting in over my head.

@in_sympathy Oh nice! Hopefully it works good.

Knowing very little about this stuff I don't know what to expect to pay for a quality welder. I see quite a few handheld ones available anywhere between 30 and $100.

I might have to pick one up but I think I will probably try that paste you mentioned first.

Thanks for all the info.

I can't believe that aftermarket batteries for some of these PDAs are so hard to come by.

@Judeau So this Fnirsi SWM-10 spot welder has arrived and it's really easy to use and provides nice joints. BUT! Out of curiosity I gently pressed a RESET button and after one press there was no mire button.

Had to disassemble the thing to find that button got totally torn away from the PCB along with the 0.1mm traces.

Had to spend rest of the evening disassembling and fixing it - which I thankfully did - and made an epoxy pillow for the button to forever stay in place - but be careful 🫠
