• This product is only designed to charge 12V lead acid, Lithium (LiFePO4) and calcium
battery. DO NOT use it to recharge non-rechargeable batteries or other type of
rechargeable batteries (e.g. NiCd, NiMH) due to the risk of fire and explosion!
• Maintenance, adjustments and repair work may only be carried out by a specialist or
a specialised workshop with access to appropriate spare parts if required.
• If you notice any damage, do not use the battery charger anymore.
• If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified persons, in order to avoid a hazard.
• Battery capacity must accord with the charger rated battery capacity.
• The unauthorized conversion and/or modification of the product is unsafe and is not
permitted.
• The product may only be set up, used or stored in places that are not accessible to
children. Danger to life!
• This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a

M 8536A 12V Battery Charger
Product Features
• Charges multiple types of Batteries: This charger is programmed to charge Lead-
Acid, Gel, AGM, Lithium (LiFePO4), and Calcium Batteries.
• Fully Automatic multi-stages charging system: Microprocessor constantly monitors
battery voltage and automatically delivers the appropriate currents to allow the
batteries to be used over a prolonged period, which means that it is ideal for the
maintenance of seasonally used motor vehicles, boats and motorcycles so that the
batteries are always ready to go and in perfect condition without damaging the
batteries.
• Auto-Memory: The charger will return to last selected mode automatically after
power re-started.
• Battery Recovery capability and dead battery detection: Capable to recover slightly
sulphated batteries and automatically identifies in case of dead battery.
• Switch-Mode Technology: Switch mode charger has high efficiency in terms of less
heat lost, much faster response during charging, compact Size, and Light Weight.
• Low Power Saving: Charger is programmed to reduce amount of charging current
once the battery is fully charged.
Protection Features
• Spark Resistant Short Circuit and Reverse Battery Protection: Prevents charger
damage if battery leads are accidentally reversed
• Over Voltage Protection: Prevents high voltage spikes from damaging sensitive
electronic components in the charger
• Electronic Current Limiting: Prevents overheating and damage caused by shorts or
excessive loads
• Automatic Over-temperature Protection: Prevents charger damage from the events
of abnormal ambient temperature or malfunction of components
• IP65: Dust and Splash resistant
Please note that the charger is protected with built-in thermal safety feature whereby
the operating temperature of the electronic is constantly being monitored. If the
operating temperature exceeds the pre-set safety level, the power of the charger
will be reduced to prevent overheating. The result is that the output current will be
reduced until the temperature drops sufficiently for a safe full performance again.

Notes on rechargeable batteries
• Make sure you observe all safety instructions and charging instructions of the battery
manufacturer.
• Before connecting the battery to the battery charger, disconnect the battery from
any loads or cables (turn off the loads first!).
• Always disconnect the ground connection from the battery before disconnecting the
positive terminal.
• Disconnect the battery from the battery charger before connecting any loads to the
battery.
• When connecting or disconnecting the battery, sparks might be produced. Therefore,
make sure there is sufficient ventilation!
• Observe the polarity when connecting the battery to the battery charger. Red
charger terminal is positive (+), black charger terminal is negative (-).
• Batteries must not be short circuited or thrown into fire. Risk of fire and explosion!
• Never try to dismantle or tamper with any type of batteries!
• Lead-acid batteries contain aggressive and corrosive acids. Avoid skin or eye contact
with battery fluids!
• On skin contact, clean the affected areas thoroughly with water and soap. On eye
contact, rinse the effected eye immediately with clear and cold running water! Then
consult a doctor immediately!
Charging a Lead-acid Battery
First make sure your battery is a 12V SLA, 12V Lithium (LiFePO4), or 12V calcium
battery.
1. Do not charge batteries with different operating voltages!
2. Disconnect all loads from the battery. If the battery is installed in a vehicle, turn off
the ignition and any other loads.
NOTE: Observe the instructions and safety information of the vehicle to find out
how the vehicle battery should be charged. Modern vehicles are equipped with
sensitive electronic parts and controls that can be damaged if you do not proceed
properly!
3. Connect the battery charger to the mains power supply (200-240V a.c. 50/60 Hz).
First connect the clamp to the negative terminal and then to the positive terminal.
4. Select a function using the mode button.
5. Connect the battery charger to the battery with the correct polarity. If the polarity is
not correct, LED 6 lights up.
6. If the Charging loop is in short circuit, LED 5 flashes. If the battery is defective in any
other way LED 7 will be lit.
7. This battery charger is equipped with an automatic memory function, i.e. whenever
AC supply is connected, it starts in last selected mode.
8. After the charging process is completed, disconnect the battery charger from the
mains supply, in reverse sequence to the connecting procedure (Step 3).

Regeneration function
This function is designed to regenerate deep-discharged batteries. It cannot be directly
selected. If a deep discharged rechargeable battery is connected to the charger, the
regeneration mode is the first mode to start.
Low charging current are used to try and bring the deep discharged rechargeable bat-
tery to a normal battery voltage again. When the battery reaches a normal voltage, the
charger will continue charging using the regular process.
Defective rechargeable batteries
The charger recognises defective rechargeable batteries automatically. In this case the
selected charging programme will not be started. LED 7 lit.
Cleaning
Disconnect the battery charger from the battery and the mains voltage before cleaning
it. Clean the outside of the product with a clean, dry, and soft cloth. Do not use harsh
cleaning agents to avoid discolouration.
Caution
• Operation under adverse ambient conditions must be avoided under all
circumstances. Adverse ambient conditions include: ambient temperatures above
40°C, flammable gases, solvents, vapours, dust, and relative humidity above 80%.
• Do not use the battery charger inside a vehicle. The battery charger must not be
used in the vicinity of flammable substances or gases.
• Ensure that there is sufficient ventilation during operation. Never cover the battery
charger or the connected battery.
• Never charge lead-acid or Lithium (LiFePO4) batteries in containers or poorly
ventilated rooms.
• Explosive gases can be generated during the charging process!
• Keep the battery charger as well as the battery away from ignition sources. Do
not smoke while handling the battery charger or the battery! There is danger of
explosion!
• Never operate the device immediately after it has been taken from a cold to a warm
room. The condensation generated can cause malfunctions and there is also the risk
of an electric shock!
