Storing your AirBelt for extended periods of time at high temperatures or with a fully charged or 
completely discharged battery can degrade its overall battery life. 
 
Depending upon the temperature of the Focus battery, it can take several minutes for the charging cycle 
to start after connecting to power. This is a normal condition and is intended for safe charging. 
AirBelt does not need to be fully discharged before recharging. It is recommended to charge it after each 
use. 
If the AirBelt power supply remains connected when it is fully charged, the four LEDs will turn off within ½ 
hour.
