
The optional AirBelt will completely recharge from its fully depleted state in
approximately 3 hours.

While charging a fully discharged battery, the LED will continue to blink until
25% capacity is reached. The LED will then turn solid.

Each of the four LEDs, 25% -100%, will blink as stated above, then turn solid
when the battery reaches it's capacity.

When all LEDs illuminate solid, the battery is fully charged and the LEDs will
remain solid for a period of time, then all four LEDs will turn off.
The incorrect use of AirBelt can cause it to get hot, ignite, and
may cause serious injury. Be sure not to pierce, strike, step on,
or drop the battery, or otherwise subject the battery to strong
impacts or shocks.
Depending upon the temperature of the AirBelt 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 AirBelt is
fully charged, the four LEDs will turn off within 15 minutes.
Lithium batteries may permanently lose capacity when exposed
to extremely hot temperatures with the batteries fully charged or
completely depleted. For extended storage, it is recommended
that batteries be charged 25 to 50% and remain within
a temperature range of 73°F (23°C) +/- 2°C.
