Safety and warnings
•
Do not leave the batteries in direct sunlight or in an area heated by sunlight. The battery could
generate heat, smoke or flames.

batteries are damaged in any other way.
•
Keep the batteries out of the reach of children and animals.
•
If fluid from the battery leaks out and makes contact with skin, wash with soap and water. The
fluid may cause irritation. If that happens please see a doctor immediately.
•
Do not expose the batteries to extreme heat, flames or liquids.
•
Do not modify or disassemble the batteries as this could result in leakage or explosion.

Battery run time, storage and recharge:
Battery run time is 15 hours, depending on connection type and screen brightness. To help preserve
the battery run time, we recommend keeping the screen brightness at or below 40% and to turn off
WiFi/Bluetooth when not needed.
All batteries self-discharge over time. The manufacturer recommends charging the batteries for a few
hours once every three months using the included charger regardless of battery level. Batteries should
be charged in temperatures between 9° C and 32° C.
