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 1 kHz should be used.
7. Characteristics
7.1 Standard Charge
This "Standard Charge" means charging the cell with charge current
1475mA and constant voltage 4.35V at 25for 3hours.
7.2 Standard Discharge Capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is
measured with discharge current of 590mA with 2.75V cut-off at 25within 1hour
after the standard charge.
Standard Discharge Capacity 2850mAh
7.3 Initial internal impedance
Initial internal impedance measured at AC 1kHz after rated charge.
Initial internal impedance 100m
7.4 Temperature Dependence of Discharge Capacity
Capacity comparison at each temperature, measured with discharge
constant current 590mA and 2.75V cut-off after the standard charge is
as follows.
