The average SmartCap Processor Card battery life is 6-7 hours with normal use, and recharges using a SmartCap Display or Base Unit within 90 minutes. Better still, swapping to a fully charged card takes just seconds!
The most important factors in determining the battery life are quality of headwear fit, and whether the headwear is operated while not worn for extended periods of time.
SP Cards should only be swapped when it is safe to do so.
NOTE: The SP Card contains a rechargeable battery that should be power cycled at least every month to ensure a long service life.
