“My boyfriend bought me this battery in addition to the women's heated jacket (5 zone) and the unisex hand warmer and upon charging all batteries, we learned that if you do not use the provided charger there is a chance the battery won't charge at all. Other than the cable specification, they charge fast and last a full 8 hour work day in my coat (on high).”
“The first time my wife used the new battery, she pushed button for heat button turned red then in a very short time button turned white, pushed button again and it did the same thing. Installed her old battery and it worked great.I think we may of got a bad battery. John Hoffman phone # 814-758-9791”
