Samsung INR18650-35E

Customer service was great and the items shipped quickly, even though I ended up ordering the wrong batteries. I wasn't aware these batteries differed at all. I needed the ones with the nipples on the positive end. Oh well. I'm sure I'll find a use for them somewhere

Hi Doug, In the past I have loaded up my soldering iron with solder and dropped a drop on the positive end, and let it cool, to give the button top. Just a thought.



As usual great service with same day shipping. THANKS FOLKS
