Function description

Figure 2 shows the characteristic charging curve for the
BAT 430.
In phase 1 of the charging process, the charging current
I is approx. 15 % of the battery capacity set on the con-
1
troller (Fig. 1, Pos. 8). The green LED flashes rapidly.
When the battery has reached the final charge voltage
U , the charging current I
1 1
the battery capacity has now been reached. The bat-
tery can be used as a starter battery. Phase 1 (main
charging) is complete when the charging current I
below approx. 1% of the battery capacity. The battery is
then approx. 97 % charged.

In phase 2, the charging current I
the set battery capacity. The green LED flashes slowly.
Phase 2 is time-controlled and lasts for 65 % of the
main charging time (phase 1). The charge voltage is
limited to U . At the end of phase 2 the green LED is

constantly lit.
Example: With a set battery capacity of 80 Ah, the
charging current I is approx. 12 A and the charging cur-
1
rent I is approx. 0.8 A.
