Manual for batteries for heated products

Our heated socks, gloves and clothing are supplied with separate rechargeable lithium-ion batteries. On this page you will read important information on how to safely charge, use and store these batteries. Proper use helps extend their lifespan and prevent unsafe situations.

What is a lithium-ion battery?

A lithium-ion battery is a powerful, rechargeable battery with a high energy density. This allows a relatively large amount of energy to be stored in a compact battery. This type of battery is widely used in products where weight, size and performance are important, such as phones, laptops, battery-operated tools and heated clothing.

Lithium-ion batteries are safe to use when used properly. However, damage, overheating, contact with moisture or improper use can cause dangerous situations. Therefore, always read the instructions carefully.
