  • It works
Replaced battery in a dog training collar. So far it works. Time will tell for longevity.

  • Great replacement for dash cam
It actually powered on and did just fine! Very pleased with it. Wish I wouldn't have cracked my screen when replacing it. Lol. My bad on that. Battery did just fine.

  • Beware! Polarity reversal in JST
Note that these batteries have the polarity reversed from the standard in the JST (just look at the posted picture)... I've ordered several others from the same vendor and all were reversed... once switched they work fine and do have protection circuitry.
