3.2 Battery safety and usage

Batteries should be stored in an ambient temperature of -4° F (–20° C) to
67.9° F (+20° C). Lithium batteries will self-discharge during storage, so they
should be fully charged before storage. Self-discharge may affect long term battery
performance. Furthermore, it is recommended that the battery should be charged in a
set time, as below;
Ambient temperature of:
-4° F (–20° C) to 67.9° F (+20° C), once every 6 months
●
67.9° F (+20° C) to 113° F (+45° C), once every 3 months
●
113° F (+45° C) to 149° F (+60° C), once every month
●
Battery should have greater than 50% charge prior to recharge.
The ambient temperature for charging should be 32° F (0° C) to 104° F
(+40° C). If under 32° F (0° C), the battery capacity will be diminished; if over
104° F (+40° C), the battery may overheat, resulting in permanent damage.
WARNING:
Never disassemble, incinerate or puncture battery
●
Never short circuit the battery
●
Keep battery dry
●
Keep out of reach of children
●
Always dispose of battery in accordance with local, state and federal regulations
●

the camera will start its measurements.
Remove the lens cap and aim at the target. Adjust the focus for the clearest target
thermal image.
