(1) Do not immerse the battery in water, and keep the battery in a
cool dry surrounding if it stands by.
(2) 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.
(3) Do not reverse the position and negative terminals.
(4) Do not connect the battery electrodes to an electrical outlet.
(5) Do not short circuit. Otherwise it will cause serious damage of
(6) Do not transport or store the battery together with metal
objects such as hairpins, necklaces, etc.
(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.
(8) Please use special lithium charger.
(9) It should be noted that the cell would be possible to be at a
over-discharged state by its self-discharge characteristics in case
the cell is not used for long time. In order to prevent
over-discharging, the cell shall be charged periodically to
maintain about 13.2V(Recommended 3 months one
cycle).Over-discharging may causes loss of cell performance,
characteristics, or battery functions.
(10) Do not disassemble battery.
