INTRODUCTION

Congratulations on your purchase of your new professional M45 Switch Mode Charger with

Pulse Maintenance. M45 is a member of a family of professional chargers from CTEK Sweden

AB. It represents the state-of-the-art technology for battery charging. A M45 will prolong the

lifetime of your battery. Read this user manual and follow the instructions carefully before using

the charger.

SAFETY

• The charger is designed for lead-acid batteries from 1,2-120Ah. Do not use the charger for

any other purpose.

• Use safety glasses and turn your head away when connecting or disconnecting a battery.

• Battery acid is corosive. Rinse immediately with water if acid comes into contact with skin or

eyes. Seek medical advice.

• Make sure that the cable is not being pinched or in contact with warm surfaces or sharp

edges.

• While charging, a battery can emit explosive gases, so it is important to avoid sparks in the

immediate area.

• Always provide for proper ventilation during charging.

• Avoid covering the charger.

• Make sure that the electrical cable does not come into contact with water.

• Never charge a frozen battery.

• Never charge a damaged battery.

• Do not place the charger on the battery while charging.

• The electrical connection must fulfil the national heavy current requirements.

• Check the cabling in the charger before use. Make sure there are no cracks in the cabling or

in the protective covering. A charger with damaged cables may not be used.

• Always check that the charger has gone over to maintenance charging mode before leaving

the charger unattended and connected for long periods. If the charger had not gone over

to maintenance charging within 3 days, this is an indication of a problem. In this case the

charger must be disconnected manually.

• All batteries fail sooner or later. A battery that fails during charging is normally taken care of

by the chargers advanced control, but certain uncommon errors in the battery can still arise.

Don’t leave the battery charger unattended for a longer period of time.

• Only mount the charger on a flat surface.

• This equipment may not be used by children or by those who can not read and understand

the manual if they are not supervised by a responsible person who can guarantee that the

battery charger is being used in a safe manner. Store and use the battery charger out of the

reach of children. Make sure that children do not play with the battery charger.

BATTERY TYPES AND SETTINGS

M45 can easily be configured to charge many different types of 12V lead-acid batteries; wet

batteries, MF, AGM och for most GEL-batteries.

The following recommendations should, however, only be seen as guidelines. When in doubt,

always consult the battery manufacturer for further instructions.

Settings are made by pressing the “MODE-button” and stepping forward by pressing the button

one step at a time, releasing the button when the required mode is reached.

Mode 14.4V/0.8A

This mode is normally used for <14Ah batteries.

Mode 14.4V/3.6A

Normal setting for wet batteries, MF and for most GEL batteries.

Mode 14.7V/3.6A

This setting is recommended for batteries at temperatures

below 5°C. It is also recommended for many AGM batteries.

This setting is not recommended for maintenance charging

when the temperature at times exceeds +5°C. In this case, the

14.4V/3.6A mode is recommended.

CHARGING

Charging batteries mounted in a vehicle:

1. The power cord should be disconnected before connecting or disconnecting the battery

leads.

2. Identify the pole that is grounded (attached to the chassis). Ground is normally connected to

the negative terminal.

3. Charging a negatively grounded battery. Connect the red wire to the positive pole of the

battery and the black cable to the vehicle’s chassis. Be careful not to connect the black cable in

the vicinity of a fuel pipe or the battery.

4. Charging a positively grounded battery. Connect the black wire to the negative pole of the

battery and the red cable to the vehicle's chassis. Be careful not to connect the red cable in the

vicinity of a fuel pipe or the battery.

Charging of a battery not connected to a vehicle:

1. The power cord should be disconnected before connecting or disconnecting the battery

leads.

2. Connect the red wire to the positive pole of the battery and the black cable to the negative

pole.

Connecting the provided cables with eyelet terminals:

Make sure that the cable is not being pinched or in contact with warm surfaces or sharp edges.

When the cable is mounted on the battery, it should not be connected to the charger. Connect

the eyelet terminals to the battery's poles - the red cable to the positive pole and the black cable

to the negative pole. After this, the quick contact can be connected.

Reverse Polarity Protection

If the battery cables are connected incorrectly, the reverse polarity protection will make sure that

the charger and the battery are not damaged. In this case, the red warning lamp (0) will be lit.

Start charging

1. Set the proper charging mode for the battery by pushing the Mode button until the correct

setting is lit. Choosing settings for your battery is described under ”BATTERY TYPES AND

SETTINGS”.

2. When you are sure the battery leads are correctly placed, connect the power cord to the

power outlet to begin charging. If the battery leads are wrongly connected, the pole-changing

switch will ensure the battery and charger are not damaged. The fault indicator

will light. In

which case start from the beginning again.

3. The charging lamp

will now indicate charging or the maintenance lamp will indicate

that the battery is fully charged. If the voltage drops the charger sends a pulse to the battery.

The length of the pulse depends on how much the voltage has dropped. The charger can be

connected for months.

4. If nothing happens: If the voltage indicator is lit but no other lamp is lit there could be a bad

connection to the battery or chassis or the battery could be faulty. Check the wall power outlet.

If you experience problems: start with the sensitive connection between the battery clamps and

the charger.

5. Charging can be stopped at any time by disconnecting the supply cord or by setting the

charger on Standby. Always remove the power cord from the power outlet before disconnecting

the battery leads from a battery in a vehicle. When you stop charging a battery in a vehicle,

remove the cable from the chassis before removing the other cable.

6. If the charger lamp and the maintenance-charger lamp are ashing alternately, the reason

for this is due to:

• An interruption during charging, due to a loose connection or because the battery has

ceased to work.

• The battery has become sulphated. If the lamps ash for more than 30 minutes, this indica-

tes that the battery is dead and needs to be replaced.

• If there is an interval of more than 10 seconds between the ashes, this indicates that the

battery has a high self-discharge rate and may need to be replaced.

CHARGING PHASES

M45 operates in a four step fully automatic cycle. It begins charging with an almost constant

current (0.8A or 3.6A) until maximum voltage (14.4V or 14.7V) is reached. The charger changes

mode at this point. It locks the voltage at maximum level and allows the current to drop. The

M45 switches automatically to pulse maintenance charging when the current drops to 0.4A.

The charging cycle restarts if the battery voltage drops to 12.9V.

Desulphation - Desulphation with pulsing for sulphated batteries.

Bulk - Charging where 80% of the energy is returned. The charger delivers an almost constant

current until the battery voltage reaches maximum level.

Absorption - Charging up to almost 100%. The charge current falls and the voltage is kept

constant at the maximum level.

Pulse - Maintenance phase, where the charger delivers a pulse if the battery voltage drops.

Charging varies between 95% and 100%. The battery receives a pulse when the voltage

reduces. Keep the battery in good condition when not in use. The charger can be connected

for months.

TEMPERATURE PROTECTION

M45 is protected from being overheated. The power will be reduced if the ambient temperature

is raised.

MAINTENANCE

The charger is maintenance free. Note that disassembly of the charger is not permitted and

will void the warranty. If the power cord is damaged, the charger must be left to the reseller for

maintenance. The case can be cleaned with a soft damp cloth and mild cleanser. The charger

should be disconnected from the power while cleaning.

EQUIPMENT

M45 is delivered with a set of battery leads with battery pole clamps and a set of battery leads

with eyelet terminals.
