Caution
Battery Use Information
Storage
1) The device with a battery should not be left a long time with
discharged status before delivered to the customer.
If you need to store our device for a long time, It is strongly
recommended that
•
checking the battery voltage level every 3 Months to avoid
efficiency reduction.
•
the battery voltage level is maintained above 3.0V by regular
charging.
(Please keep the voltage level range 3.7V~3.95V, not a
full level)
2) All batteries should be avoided to store with corrosive material,
fire, heat, and please keep clean and dry environment.
3) Please keep temperature range -
20°C~45°C and humidity less
than 75%.
Handling and Use
1) Please do not place or use batteries on hot surfaces, or near
conductive/flammable material, water, strong oxidizers and acids.
2) If you aware that batteries are deformed, please take off from
devices and never use it. (Such as swelling, odor by heating)
3) Please do not charge for much longer time than the normal
charging time. It can cause heating, fuming, deformation.
4) If batteries are leaking or smell, It may present a fire risk.
Disposal
1) Please dispose damaged or worn-
out batteries into a battery
recycle bin.
2) To check the general condition of you batteries, charge them,
let them rest for an hour, then measure the voltage. If you
