2A-50C
Ni-Cd
Size : AA
Specification
Type
: Rechargeable nickel cadmium battery
Dimension
D............................................................. 14 0.2mm
d........................................................... 8.0 0.2mm
H.......................................................... 48.0 0.5mm
Nominal Voltage
................................................. 1.2V
Weight
............................................................... ~22g
Internal resistance
At 1000Hz..................................................... ~32m
Capacity
Rated capacity...............................................500mAh
1) At 0.2C discharge...100%~105% of rated
capacity.
2) At 0.5C discharge........95~100% of rated
capacity.
3) At 1C discharge.............90~95% of rated
capacity.
1) Slow charge 25mA
x
15hrs. (0-45 C)
To avoid overcharge, a timer is used to terminate the
charging after 150% capacity input.
2) Normal charge 250mA
x
3hrs. (10-40 C)
To avoid overcharge, a timer is used to terminate the
charging after 150% capacity input. In addition, a
temperature cut off (TCO) device, i.e. thermostat,
with cut off temperature at 55 C must be used for
safety purpose.
3) Quick charge 500300mA
x
1.2hrs. (10-40 C)
With charging current over 0.5C A, a joint use of dT
or - V cut off is required. For dT control, a maximum
allowable temperature rise is 1 C/min. Or if - V
control is used, the maximum allowable voltage
decrease is 10 mV/cell. TCO device with cut off
temperature at 60 C should be used at the same
time.
Storage:
1) Storage Temperature........................-10 C to 45 C
Remark: Weight and internal impedence are for reference only.
