1) Slow charge 55mA 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. (10-45 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 550mA x 1.2hrs. (10-45 C)
With charging current over 0.5C A, a joint use of dT
or - V cut off is required. For dT control, a maximum

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.
