Joseph Pitra (Westminster, US)
New Battery

It works just fine and is easier to use then the original battery. The warmer did not include a charging cord when I bought it so when I bought the new charging cord, I bought the battery as well to be sure I had at least one I could recharge. Had the warmer for 2 seasons now and finally got to feel it warmed up.

Spare battery

I purchased this battery as a backup because it takes more time to charge the battery to use the hand warmer in a morning hunt and again for an afternoon sit, I don’t want to be hunting without the hand warmer it works that well
