Charging phase details
Pre Analysis
The charger checks if the battery is correctly connected.
The battery’s charge level (V) and total capacity (Ah) is
measured to determine the correct settings for charging.
Charging
The charger starts charging the battery with constant current
up to 14.4V (at 20°C). The charge voltage is then held constant
at 14.4V and the charging current is reduced until it is below
a defined level. The charge voltage then drops to 13.8V,
before the long-term charging phase starts.

During charging, battery charge is shown by the number of
LEDs illuminated. The blinking segment above these LEDs
indicates active charging. Once full battery charge is reached,
all 5 LED segments remain illuminated.
If the measured battery voltage is below 4.5V, the charger
will enter Error Mode.
Post Analysis
The charger analyses the battery again after the charging
phase. If the charger detects an error in the battery, the warning
triangle will flash. Post analysis can detect batteries with
a short circuit in individual cells. This cannot be detected in
the pre analysis. If the battery voltage drops below 12.6V
within 2min, the charger will go into error mode. The charging
sequence will be stopped.
Long-term charging
After the battery is fully charged, the charger will go in to Sleep
Mode. This is indicated by all battery LEDs slowly pulsating.
This mode has a very low power consumption.
After a week in Sleep Mode, the charger will wake up and
begin a new charging cycle.
The charger will also wake up and start a charging cycle
if battery voltage drops below 12.6V.
