PRECAUTIONS FOR USING LITHIUM ION RECHARGEABLE CELL

The precautions described below are important to assure the performance and safety of designed pack. Mishandling may cause cell leakage, heat, smoke, explosion or fire. Please follow instructions carefully.

Intended Use

Cordless screw driver, Cordless drill/driver, Cordless impact driver, Cordless tubing cutter, Cordless angle grinder, Cordless polisher/waxer, Power tool, Electrical vehicle, PHEV.

Handling Precautions

Charging

The lithium ion rechargeable cell is to be charged by “constant current/constant voltage” method. The lithium ion cell is charged at a constant current (CC Mode) until the cell voltage reaches a specific voltage, followed by a constant voltage charge (CV Mode) at the specific voltage. The charging current at this constant voltage                       tapers off. As long as the tapering current is down to a particular current, the charge process is deemed complete.

a.Charge voltage:

Do not exceed the specified charge voltage (4.2V per single cell). If the cells are used in battery packs, the maximum voltage is 4.2 x N (N= number of cells connected in series) V.

b. Charge current:

Charge the cell at the specified charge current listed in section 4.10 or less.

c. Charge temperature:

Charge the cell at the temperature range of 0 oC ~ 60 oC. Due consideration should also be given to the arrangement of the battery pack so that it is in that temperature range even though it is effected by heat generated from the cell

 Reverse charging:

The cell must be prevented from reverse-polarity charging.

Discharging

A lithium ion rechargeable cell starts to discharge at 4.2V and terminates at a cut off voltage of 2.5V.

a.Discharge current:

Discharge the cell at the specified discharge current listed in section 4.10 or less. In case a peak current of higher than maximum discharge current depending on the pulse interval may reduce the cell capacity.

b.Discharge temperature:

Discharge the cell at temperature range from –40oC to 60oC. At a temperature of –30oC or less, the cell will show a significant decrease in discharge capacity.

c. Discharge termination voltage/Over discharge:

Avoid discharge to voltage less than 2.5V per single cell. A leakage current to the equipment may over discharge the cell, which may damage the performance of cell.
