And formany 24 V AGM batteriesNote:1) This charger is only valid for batteries with a battery capacity > 14 Ah.2) The maintenance mode can be used to maintain the battery voltage if the battery isnot used for an extended period of time.3) For regeneration mode, make sure that all connections between the battery and thevehicle electrical system are disconnected.4) For certain vehicles, it is important not to disconnect the vehicle electronics fromthe power supply when changing the battery. In such cases, the power supply modecan be used to supply power to the vehicle electronics during battery replacement.If the load voltage is below 7.5 V, the charger will switch to standby mode. There is noreverse polarity protection in this mode.4.1 Pulse chargingThis is an automatic charging function that cannot be selected manually.◾ Modes 1 & 2:If the battery voltage is between 7.5 V (± 0.5 V) and 10.5 V (± 0.5 V) at the start ofthe charging process, the charger will automatically switch to pulse charging.◾ Modes 6 & 7:If the battery voltage is between 16 V (± 0.5 V) and 21 V (± 0.5 V) at the start of thecharging process, the charger will automatically switch to pulse charging.4.2 Trickle charging phaseThe charger has an automatic trickle charging phase with max. 800 mA at full charge.4.3 Maintenance phaseWhen the battery is fully charged, “100%” LED lights up. The charger will start themaintenance phase to keep the battery capacity in full condition.4.4 Memory functionIf the charger is disconnected from the mains during the charging process, the devicesaves the previously selected mode. When reconnected to the mains and with the samebattery type (12V or 24V), the device will automatically start in the last mode.Caution: If the connected battery type is different from the last one used (e.g. if youwere in cold/AGM mode last time and you need to connect a normal lead-acid batterythis time), please reselect the mode manually to avoid overcharging or damage.There is no memory function for mode 3 (maintenance mode), mode 4 (regenerationmode) & mode 5 (power supply mode).4.5 Battery detectionOnce the charger is connected to a 14.6 V - 21 V battery, 12 V & 24 V LEDs will flash al-
