Important Safety Rules for Optional AirBelt
The incorrect use of AirBelt can cause the battery to get hot,
ignite, and can 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.
Replace safety cap on AirBelt cord when not in use.
Do not attempt to charge the optional AirBelt with the FreeStyle
Universal AC/DC power supply, or AirBelt can be damaged.
Use only the AirBelt power supply provided to charge AirBelt.
Depending upon the temperature of the AirBelt, 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 AirBelt after each use.
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.
