Only needed the batteries

I have been using Hotronics for 20 plus years. I only needed the batteries. However the batteries are phased out for new technology and the S4 heating system model battery is sold out everywhere. Utah Ski Gear offered the lowest price for the entire set up and as a first time purchase an extra 10% off. I will purchase from Utah Ski Gear again.

This is my third set of Hotronics. Once you use boot heaters, you can’t go without. The only problem with this type of heater is that unless you wrap the cord in duct tape or something else to strengthen it, the cord will fracture and fail over time. Not a disaster as you can just replace the footpad and covering. The batteries are good for many, many recharges.
