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.
