How to select your battery boot heating system!
First, select a battery heating system!
A heating system is batteries and heating elements. You have 4 options.- Batteries and charger- (left column) If you have a pre-installed heating elements in your boots, (you'll know this by the wires coming out the top of your boots) all you need are the batteries and charger.
- Batteries with heat element- (second column) If you do not have pre-installed heating elements and have custom insoles or very close fitting boots, this is the best way to heat your toes.
- Batteries with trim to fit insoles- (third column) This is our most popular system! If you do not have pre-installed heating elements or custom insoles, this is the easiest system to install! The one size fits all insoles have the heating elements pre-installed in the toe area. All you do is trim the insole to size and install.
- Batteries with supportive insoles- (the right column) If you do not have pre-installed heating elements or custom insoles, this is easy to install and the supportive insoles offer extra support for comfort. The heating elements are pre-installed in the insoles at the toes.
Next, select your battery type!
The more expensive the battery option, the longer your heat will last.- Hotronic offers two options, e3 and e4 - Both use rechargeable three or four cell nickel metal hydride batteries.
- Therm-ic offers more battery options. The Basic uses AA batteries. The Max and SuperMax uses nickel metal hydride batteries. The Smartpacks uses small light weight rechargeable Lithium-ion batteries. Some can be operated with a remote control.
