4. Outline Dimensions
See the attachment (Fig. 1)
5. Appearance
There shall be no such defects as scratch, rust, discoloration, leakage which
may adversely affect commercial value of the cell.
6. Standard Test Conditions
6.1 Environmental Conditions
Unless otherwise specified, all tests stated in this specification are
conducted at temperature 25±5and humidity 65±20%.
6.2 Measuring Equipment
(1) Ammeter and Voltmeter
The ammeter and voltmeter should have an accuracy of
the grade 0.5 or higher.
(2) Slide caliper
The slide caliper should have 0.01 mm scale.
(3) Impedance meter
The impedance meter with AC 1kHz should be used.
7. Characteristics
7.1 Standard Charge
This "Standard Charge" means charging the cell with charge current
0.91A and constant voltage 4.2V 100mA cut-off at 25.
7.2 Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is
measured with discharge current of 4A with 2.5V cut-off at 25within 1hour
after the standard charge.
Standard Discharge Capacity 1250mAh
7.3 Initial internal impedance
Initial internal impedance measured at AC 1kHz after standard charge.
Initial internal impedance 30m
7.4 Temperature Dependence of Discharge Capacity
Capacity comparison at each temperature, measured with discharge
constant current 4A and 2.5V cut-off after the standard discharge is
as follows.

7.8-1 Cycle Life
Each cycle is an interval between the charge (charge current 1.3A) with 100mA cut-off
and the discharge (discharge current 10A) with 2.5V cut-off.
Capacity after 600cycles,
Capacity 750mAh (60% of the standard capacity at 25)
7.8-2 Cycle Life2
Each cycle is an interval between the charge (charge current 1.3A) with 100mA cut-off
and the discharge (discharge current 15A) with 2.5V cut-off.
Capacity after 350cycles,
Capacity 750mAh (60% of the standard capacity at 25)
7.9 Storage Characteristics
Capacity after storage for 30days at 60from the standard charge,
measured with discharge current 4A with 2.5V cut-off at 25.
