    Perfect fit for my handheld TENS machine.
  

*by D***. on Reviewed in the United States on August 12, 2024*

My TENS machine stopped charging. It only turns on when plugged in. This battery worked perfectly. Now I can charge the battery and it works for a few days depending on  how often you use it. Very happy with the battery.
