    Great long lasting batteries

    I like these jackets a lot and plan on keeping them for a long time as I have three so what could be better then having a spare battery in case I forget to charge them after a week or so and the flat batteries work great

    Extra Juice

    These batteries last a long time even when they are on High output on the jacket. I got an extra one because I wanted to keep staying warm when the first one runs out. And for long over night adventures
