1) Slow charge 140mA x 15hrs. (0-45 C)

To avoid overcharge, a timer is used to terminate the

charging after 150% capacity input.

2) Normal charge 700mA x 2-3hrs. (10-45 C)

To avoid overcharge, a timer is used to terminate the

charging after 150% capacity input. 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. In addition, a

temperature cut off (TCO) device, i.e. thermostat,

with cut off temperature at 55 C must be used for

safety purpose.
