PARAMETERS
Check that the current is <75 A in the red sector of the SOC indicator
0...100 A
Check that the current is <50 A at a temp of -10°C<x<+55°C and an SOC >50%
SOC >75% current should be <30 A
0...50 A SOC <70% current should be <10 A at temp <5°C
SOC <70% current should be <15 A at temp <55°C
During mains charging: SOC<75% reference current is 20A ± 2A
(5°C<temp<50°C)
0...22 A During mains charging: 75%<SOC<100% reference current drops to 3A
(5°C<temp<50°C)
T<5°C and >50°C, reference current drops
41.2 Volts Reference charge voltage limited to 40V±1V at t<0°C±1°C and t>60°C±1°C
If above 4.32 V, the battery will not arm (if this occurs with GREEN LED, replace
3.5...4.1
battery)
Volts
If above 4.12 V, excessive charge
Battery must be replaced if value is below 2.7 V.
Below 2.5 V, diagnostic communications may not be available (battery does not
arm)
3.5...4.1
From 2.5 to 2.7 V, LED flashing permanently RED (battery does not arm)
Volts
From 2.7 to 3.2 V, attempt mains charging
From 3.2 to 3.5 V, battery does not function according to specifications
From 3.5 to 4.1 V, battery functions correctly
