Electric socks and other electric heated products with disposable batteries aren’t very popular in this market. Most of these heated products last half a day at most, making disposable batteries a very cost-ineffective option.

Some heated products using disposable batteries can still have their advantages. As such, it’s always recommended to use rechargeable AA batteries instead of those that can only be used once.

Rechargeable batteries are not only better for the environment, but will also significantly reduce the costs of keeping your feet warm in the long run.
