Duration of heat depends on the heat setting you use.
It is obvious that well-insulated shoes keep feet better warm, so you can set the temperature of the heated insoles at a lower level which significantly prolong the heat duration.

Battery characteristics :

• 1 x Li-ion battery 7.4V / 2000 mAh
• With proper use, rechargeable up to 500 x without significant capacity loss.
