Full battery performance is achieved after two or three complete charge and discharge cycles.
The battery can be charged and discharged hundreds of times. After 500 cycles the operation time of a fully charged battery is expected to be at around 80%.
Leaving the product in hot temperatures may reduce the capacity and lifetime of the battery.
Unplug the charger from the Mini Mic/Phone Clip and from the electrical outlet when not in use for extended periods of time.
If left unused, a fully charged battery will lose its charge over time.
