Precautions and Warnings for Use and Handling
of Lithium Polymer Battery
PREFACE
In order to get the optimum performance and reliable safety, consumers shall read and take the
following instructions and precautions when use and handle the Lithium Polymer (Li-Po) batteries.
1. CHARGING
1-1 Charging current should not be more than the maximum charge current specified in the
Product Specification (normally 0.5C-1.0C or lower). Charging with higher current may damage
the cell or even lead to safety problem, e.g. overheating or leakage.
1-2 Charging voltage shall not be more than that specified in the Product Specification
(4.2V/cell). 4.25V is the maximum charging voltage for each cell. Never charge the battery
in series and be sure that each single cell has a separated charging circuit with a max. charging
voltage of 4.25V.Or the battery may be overcharged, and lead to fire or explosion. The user is
fully responsible to the result of misusing the battery.
1-3 Charging temperature: The cell should be charged within the range of temperatures specified
in the Product Specification. Stop charging imm ediately when the surface temperature of the
battery is over 50
℃．
1-4 Reverse charging: Please make sure the polarities of cells are connected properly before
charging. Reverse charging is strictly prohibited. Reverse charging cannot charge the cells but
will deteriorate their charging/discharging and safety characteristics, or even lead to fire or
explosion.
2. DISCHARGING
2-1 Discharging current: The cell shall be discharged at the current no more than the maximum
discharging current specified in the Product Specification. Over current discharging may damage
the battery and cause over-heat.
2-2 Operation temperature: Use the battery within the temperature range specified in the Product
Specification. Stop using when temperature is over 70
℃．
2-3Over-discharging:Over-discharging will deteriorate thecell' s performance and characteristics.
Do not over-discharge a battery below 2.75V/cell.
3. STORAGE
If you intend to keep the battery for a long time (3 months or longer), it is strongly recommended
that the battery shall be stored under the environment with temperature 10-25
℃
, low humidity
and without corrosive gas. The battery should be charged every six months to ensure that each
cell' s storage voltage is 3.6-3.9V.
OTHERS
>The aluminum packing foil is very soft that it will be easily left scratches. Please do not hit the
cell with any sharp edge parts.
>Don' t fall, hit or bend the battery. It may cause fire or explosion.
>Short circuit the battery is strictly prohibited, it may damage the battery seriously.
>Never disassemble the battery. It may cause fire.
>Never dispose of the battery in fire. It is very dangerous and strictly prohibited.
>To place the battery into liquid such as water is strictly prohibited.
>Always remove battery from car when charging. Charging the battery in a car is forbidden and
is dangerous.
>Avoid vibration, shock or extruding the battery. Handle carefully when moving it.
