right out of the box the battery only works in the "high setting." It does work but not as advertised.

Charge outside for a long time
October 24, 2018
I purchased the "upgrade" battery to double my "heating" time outdoors before recharging. So far so good. I have yet to run into an issue of running out of battery before getting back inside out of the cold. I typically only run my vest on the 50% or 25% setting and been out for hours without a hitch several times without the need to recharge this battery only once. The battery is supposed to last 20 hours on low and even though I've not timed it, it does last a long time without needing to recharge. I'll find out this winter when I'm ice fishing if this battery is worth the price of admission but so far, I've not been disappointed and "left out in the cold".
  • Last a long time reducing the need to charge it and increasing your warmth run time significantly.
  • It's a bit larger and heavier than the original battery and you know it's there.
