-Some Cautions about 21700 Battery-
(1)Do not disassemble battery.
(2)Do not reverse the position and negative terminals.
(3)Do not connect the battery electrodes to an electrical outlet.
(4)Do not short circuit. Otherwise it will cause serious damage of the battery.
(5)Do not immerse the battery in water, and keep the battery in a cool dry surrounding if it stands by.
(6)Do not use or leave the battery at high temperature as fire or heater. Otherwise, it can overheat or fire or its performance will be degenerate and its service life will be decreased.
(7)Do not use the battery in a location where static electricity and magnetic field is great, otherwise, the safety devices may be damaged, causing hidden trouble of safety.Turn off the switch on its base.
(8)Do not transport or store the battery together with metal objects such as hairpins, necklaces, etc.
(9)Please use special lithium charger.
