Step 7 "Trickle charge": If the battery remains connected to
the charger, trickle charging takes place once every 24 hours if
necessary.
9 | Charging process
Once a connection has been established with the mains (220 V –
240 V/50 Hz), the "Mains" LED
test mode if a battery is connected.
If a battery is incorrectly connected, the "Wrong polarity" LED lights
up
If the voltage of the connected battery is higher than 14.3 V, the
"Error" LED flashes
and 14.3 V, the device enters charging mode.
If the charger detects a deeply discharged battery (<4 V), this
is indicated by the "Pre-charging" LED
gently charged up to 4 V. If the charging voltage increases to above
4 V, this LED is switched off and the charging operation starts

If a battery voltage of 4 V is not reached within 24 hours, the
"Error"
and the charger interrupts the charging operation.
If a non-discharged lithium-ion battery is connected to the charger,
the battery is first charged with constant current (I-phase) until 14,3
volts is reached. The voltage is then held constant
(U phase) and the charging current adapts to the level of charge in
the battery. The fuller the battery, the lower the charging current.
If the charging current falls below approx. 300 mA, the charging
process is halted and the charger switches automatically to test
mode and the "Charging" LED
defined current in pulses from the battery for 15 minutes If the
voltage of the loaded battery falls back to its rated value, this
indicates a high self-discharge or low residual capacity. If this is the
