this document is for reference only and should not be used as a basis
for product guarantee or warranty. For applications other than those
described here, please contact your nearest GP Sales and Marketing

office or Distributors.
Manufacturer reserves the right to alter, amend the design, model and
specification without prior notice.

7. Charge state of cell before shipment

Charge from 10% to 50% according to delivery condition.

8. Safety precaution

Please follow the safety precaution carefully as improper handling
of lithium ion batteries may result in injury or damage from
electrolyte leakage, heating ignition or explosion. To ensure safety,
consult with GP regarding the charge and discharge specifications,
equipment structure, warning labels and other important details when
designing equipment to use GP rechargeable lithium ion batteries.

Never charge the battery above 4.20V.
Never reverse charge the battery.
Never heat or incinerate the battery.
Never pierce, crush or cause mechanical damage to the battery.
Never charge a battery at high temperature condition, such as at
or near a fire.
Never short circuit the battery.
Never discharge a battery to below 2.8V per cell.
Never allow the battery to get wet or be immersed in water.
For long period of storage, temperature should be below 45oC.
After long period of storage, battery may required some cycling

The Cell(s)/Battery Pack shall be used with a PCM which can
protect Cell(s)/Battery Pack properly.
The PCM shall have functions of (a) overcharging protection;
(b) over-discharging protection and (c) over current protection,
to maintain safety and significant deterioration of cell
performance. The over current can occur by external short

- Overcharging prevention function shall work if any one of the
cell of the battery reached to 4.35V or above which charging
should be stopped.
- Overdischarging prevention function shall work if the Cell(S)/
Battery Pack reaches to below 2.15V.
- It is recommended that the dissipation current of PCM shall
be designed to minimal such as 0.5 microamperes or less after
the over-discharge prevention function works.
- The protection function shall monitor each cell for
controlling the current throughout the time.
Design of Protection Circuit Module(PCM)
a. PCM shall be located away from the gas-release vent of the cell
as much as possible.
b. Circuit pattern of PCM shall be away from each other as much as
