Review on 🔌 Zerostart 2800063 Electric Battery Blanket: Efficient Battery Heater Wrap for 36-Inch Batteries - CSA Approved, 120V, 80W, Black by Eloy Boelkens

We had a VERY COLD and snowy winter in northern Minnesota. Our temperature didn't rise above "0" for 2 months with most nights being -25 to -38 and the frost dropping to -60. Wrapped this around our RAM battery on January 4th and plugged it in every day from 3pm to 3:30am. until 10 days ago. Worked like clockwork, the car started every day with no problems. We previously bought a smaller size to pack our alternator battery and that worked great too. Very happy with the purchase and recommended if you have a similar situation!
