3. Proper use
The charger is designed for charging non-
maintenance-free or maintenance-free 12V lead
acid batteries (wet / Ca/Ca / EFB batteries) and
for lead gel and AGM batteries which are used in
motor vehicles.
The 12V M charging program is suitable for
trickle charging and charging of batteries with
small battery capacities. The SUPPLY function
enables the device to be used as a buff er power
supply as well, e.g. while changing a battery or
for the operation of 12V d.c. consumers (observe
the max. power consumption). The RECOND
program is intended to be used only for bringing
lead acid batteries (not for AGM and GEL
batteries) which have undergone exhaustive
discharge back to life. Only use this program for a

Overview

1. Function Description
2. Usage Features
3. Maintenance Features

This document describes a microprocessor-controlled automatic charger designed for various 12V lead-acid batteries. It is suitable for charging non-maintenance-free, maintenance-free (wet, Ca/Ca, EFB), lead gel, and AGM batteries commonly found in motor vehicles. The charger is intended for mobile use and not for permanent installation in caravans, mobile homes, or similar vehicles. It should not be exposed to rain or snow.

Function Description

The charger operates with several charging programs tailored to different battery types and conditions:

• 12V STD (Standard): This is the default program for lead-acid batteries (wet, Ca/Ca, EFB) and gel batteries. It is automatically selected when the charger is used for the first time.
• 12V AGM: Specifically for AGM batteries. This program can be selected by pressing the "Mode" button from the 12V STD program.
• Winter: Recommended for cold weather conditions (ambient temperature of -20°C to +5°C) for normal lead-acid batteries (wet/Ca/Ca). It is accessible by pressing the "Mode" button from the 12V AGM program.
• 12V M: Designed for batteries with low capacity (e.g., 3-60 Ah) and for trickle charging of all listed batteries. This program is selected by pressing the "Mode" button from the "Winter" program.
• RECOND: This program is for restoring the charging capability of lead-acid batteries that have undergone exhaustive discharge. It uses a higher end-of-charge voltage and constant current charging. Important: This program requires monitoring every half hour and should not exceed 4 hours. It is not suitable for sealed VRLA batteries (AGM or GEL).
• SUPPLY: This function provides 12V DC voltage, useful when changing a battery (to maintain vehicle electronics) or for operating 12V DC consumers. Protection against swapped poles is not available in this mode, so correct polarity is crucial to prevent damage.

The integrated microprocessor enables multi-step charging, including a maintenance charging step that keeps the battery capacity at 95-100%, ensuring it remains fully charged. The charging operation does not require constant monitoring, but for extended charging, it's advisable not to leave the battery unattended to allow disconnection in case of a fault.

Usage Features

Before connecting to the power supply, ensure the charger's specifications match the supply voltage. Never charge frozen batteries.

• Connecting the Battery:
  1. If applicable, release or remove battery stoppers.
  2. Check the acid level and top up with distilled water if necessary. Battery acid is aggressive; rinse off splashes thoroughly and seek medical advice if needed.
  3. First, connect the red charging cable to the positive pole of the battery.
  4. Then, connect the black charging cable to the vehicle's bodywork, away from the battery and the petrol pipe.
  5. In vehicles with positive earthing (where the positive battery pole is connected to the bodywork), connect the black charger cable to the negative battery pole first, then the red charger cable to the bodywork away from the battery and petrol pipe.
  6. After connecting the battery, plug the charger into a socket.
  7. Select the desired charging program using the "Mode" button. To access the RECOND program, hold the "Mode" button for 5 seconds. To switch back from RECOND or SUPPLY to 12V STD, hold the "Mode" button for 5 seconds.
• LCD Display: The LCD display shows the selected program, charging voltage, battery status (faulty, fully charged, reverse polarity/short-circuit), and charge status in percent.
• Fault Indication: The fault indicator (G) flashes if the battery voltage is outside the 3.5V to 15V range, indicating an unsuitable or defective battery. It also flashes for reverse polarity or short-circuits at the clamps.
• Overload Protection: The charger has electronic protection against overloading, short-circuits, and swapped poles in STD, AGM, Winter, and 12V M programs. Fine fuses are also fitted and must be replaced with the same amp value if defective.
• Finishing Charging:
  1. Unplug the charger from the socket.
  2. First, disconnect the black charging cable from the bodywork.
  3. Then, disconnect the red charging cable from the positive pole of the battery.
  4. In positive earthing cases, disconnect the red charging cable from the bodywork first, then the black charging cable from the battery.
  5. Screw or push battery stoppers back into position if applicable.
  6. It is recommended to completely remove the charger from the battery when not in use, as it draws a small amount of electricity even when unplugged from the mains but still connected to the battery.

Maintenance Features

• Battery Maintenance:
  • Ensure the battery is always securely fitted.
  • Maintain a perfect connection to the vehicle's electrical system.
  • Keep the battery clean and dry.
  • Apply a thin coating of acid-free, acid-resistant grease (Vaseline) to connection terminals.
  • For non-maintenance-free batteries, check the acid level approximately every 4 weeks and top up with distilled water if necessary.
• Charger Cleaning:
  • Always unplug the mains power plug before cleaning.
  • Keep all safety devices, air vents, and the motor housing free of dirt and dust.
  • Wipe the equipment with a clean cloth or blow it with compressed air at low pressure.
  • Clean the device regularly with a moist cloth and soft soap. Avoid cleaning agents or solvents that could damage plastic parts.
  • Ensure no water seeps into the device, as this increases the risk of electric shock.
  • Store the charger in a dry room. Clean any corrosion off the charging terminals.
• Internal Maintenance: There are no parts inside the equipment that require additional maintenance.
• Waste Disposal: Dispose of batteries through motor vehicle workshops, special collection points, or special waste collection points. The equipment and packaging materials should be recycled. Do not dispose of defective equipment in household refuse; take it to a suitable collection center.
