How often do you clean your e-cigarette battery? If you answered “never” or “rarely” keep on readin’! Vapor4Life recommends giving batteries a good scrubbing weekly. Regular battery cleaning will keep it functioning and charging properly. Often a decrease in performance is the result of a blocked connection point. This is the area where a cartomizer or tank screws on the battery. If batteries are not cleaned regularly, then over time this connection part will become blocked with debris.
