Battery life
Batteries should be replaced as needed just as you would with any other
electronic device. Battery life varies according to the programs used
each day, the thickness of skin covering your implant, and the size and
type of battery.
The rechargeable battery’s lifespan is at least 365 charge cycles. A
completely empty rechargeable battery will take approximately four
hours to recharge.
Rechargeable batteries may take longer to fully recharge with age. To
get the longest life from the rechargeable batteries, always recharge
before use.
Battery life, charge cycles and lifespan
• Battery life means the time a device will run before the
disposable batteries must be replaced, or the rechargeable
batteries recharged.
• Battery charge cycle means a cycle of one full charge and
discharge of the rechargeable battery.
• Battery lifespan means the total number of charge cycles a
rechargeable battery will last before the battery life degrades
to 80% of its original fully charged capacity.
