Review: Great Battery Spot Welder with a Little Help from YouTube! - I recently used a battery spot welder, and overall, it’s been excellent! The initial instructions were a bit confusing, but with a few helpful YouTube videos, I quickly got the hang of it. I used this spot welder to replace batteries that had a coating making it impossible to solder to the sides. The spot welder worked perfectly for this task, allowing me to make strong, clean welds with ease. Once I figured out how to use it, the performance was fantastic. It made the battery replacement process much smoother and more efficient than soldering. Overall, I’d give this battery spot welder five stars. With a bit of guidance from online resources, it’s a reliable tool that gets the job done effectively.
Review: Works great! Great value! - I read other people's reviews and I was a little scared. But, I bought it anyway. I love it! It has worked great for me. I have been using .1mm nickel strips on setting 3, for 18650 batteries, and it works great. I have not used the thicker .2mm strips that were supplied with the unit. I thought there would be a loud "pop" like I was TIG welding or something. Nope. Very small flash and a small puff of smoke. This is great for hobbyists like myself that don't like to see electronics (laptop batteries, handheld radios, vape pens, etc.) go to waste because of dead batteries. If you have a need for a light duty spot welder, I recommend this one!

### ⭐⭐⭐⭐ Good for ~100 welds before recharge
*by M***R on March 28, 2023*

I just got this spot-welder last week and have used it to rebuild one 18v Dewalt XRP-9096 so far. After about 100 or so welds, it started to noticeably loose power and the welds didn't stick as well as when I started. I forced it through to the end but the last few tabs required me to redo with solder, which puts a lot of heat into the cells. I could have a longer life between recharges but what do you expect for $40? I guess it's better than soldering and quicker too. Sharpening the points w the included file helps to keep it welding better, pretty good for the money I'd recon. JM
