operation type 4 = maintenance
battery type 20 = enclosed aircraft nickel-cadmium battery.
2 stage number = Stage 6
3 stage name = topping charge 2
4 00:36:38 = current time
5 29.6 V = current battery voltage
6 0.40 А = current charging current
The charging voltage grows and can exceed 31 V. Because of
this all the batteries reach the final charging voltage. The
capacities of the cells equalize. Extra charging 2 with the
current 0.4 А (1/10 of the nominal capacity) is supplied into the
cells for 90 minutes.
7 4.019 Аh The capacity counting continues. The main charging plus extra
charging. The total is 4 Аh + 2 minutes of 0.4 А = 0.019 Аh; the
total is 4.019 Аh.
8 0060 MIN Indication of the charging time.
After 75 min a beep sounds.
а) the voltage of the cells should measured with the measuring
cable.
b) distilled water should be added into the batteries.
