Thank you
"Finiding an actual Lithium Ion 3. 7v battery these days can be daunting as many vendors use LiPo4 batteries and package them as 3. 7v. I found battery junction along this battery and it was a perfect fit for a retrofit that I was working on for a D cell battery heirloom. While not a button top, the battery still worked flawlessy for my build and the chemistry was Lithium Ion 3. 7 Rechargable as advertised. This battery also has me looking at the Fitorch P50."
