Your CENS device is powered by a zinc-air battery. To activate the battery you will need to remove a small sticky tab to allow air into the cell and initiate energy production. Once this tab is removed the activation cannot be reversed, and even if the device is not being used the battery will continue to deplete until it is exhausted, usually around 45 days after activation.
When used to power a CENS device continually a size 13 zinc-air battery has been shown to last for around 400 hours.
Due to the limitations detailed above, real-world usage figures will be wholly dependent upon how frequently a device is used following battery activation, i.e., when used for 6-8 hours a day, 2-3 times a week, the battery will provide more useable power than if only used once or twice a month.
