LITHIUM-ION BATTERIES

Recharge the battery for first time use or after long period of storage:
The voltage of the battery may drop due to self-discharge during long 

period of storage. Always fully charge the battery before use.
Cautions for charging and usage:

• Using a PC or USB battery charger with an output current of 500 mA or 

more is recommended for charging.

• Be sure that no dust or other foreign objects are attached to the plug of 

the USB cable before charging.

• Once charging is completed, be sure to disconnect the USB cable from 

the charging port.

• Charging and lighting times are approximate values, and will vary by 

environmental and user conditions.

• Charging, discharging, and storing in high temperatures will cause the 

rechargeable battery to deteriorate faster. Do not place the light inside a 

vehicle or near a heater. Make sure to charge only when the ambient 

temperature is between 41˚F and 104˚F (5°C and 40°C).

• If the illumination time is significantly reduced even after proper charging, 

the rechargeable battery may be nearing the end of its service life.

Cautions on storage:

• If the device will not be used for a long period of time, store it in a 

location that is not too hot or too humid. 

• Charge the battery for about 30 minutes every 6 months.
