CTEK M 300 Incl. STARTER - Manual (Page 9)

5. If the charging lamp and maintenance charging lamp alternately flash the reason for this is
the following:
If the lamps flash a few times per second then the battery is probably sulphated. If the lamp
flashes more than 60 minutes the battery should be replaced.
If the flashing occurs with a few minutes’ interval then the battery has a high self-discharge
and may need to be replaced.
CHARGING PHASES
M300 STARTER has a four step fully automatic charging cycle. At the start of charging the
battery charger delivers maximum current to the battery and the battery voltage increases
constantly to a set level of 14.4V. At this point the voltage will be regulated and kept constant
while the charging current is successively lowered. Once the charging current has dropped
below 0.4A the charger switches to maintenance charging.
If the battery is loaded and the battery’s terminal voltage drops to 12.9V the charger automati-
cally switches back to the beginning of the four step cycle. The charger requires a reverse
voltage from the battery of at least 6V to start the charging cycle, this means that if the battery
is so deeply discharged that the terminal voltage is lower than 6V the charger cannot charge the
battery in question. A normal discharged battery has a terminal voltage of 10.5V.
Charging phases:
Desulphation - Desulphation with pulsing for sulphated batteries.
Bulk - Main charge when 80% of charging takes place. The charger delivers a constant current
until the terminal voltage has risen to the set level.
Absorption - Complete charge up to virtually 100%. The terminal voltage is maintained at the
set level. During this phase the current drops successively so the terminal voltage does not be-
come too high. If the absorption phase has been in progress for more than 18 hours the charger
switches to maintenance charging. This function prevents damage if the battery is faulty.
Pulse - Maintenance charging. State of charge varies between 95% and 100%. The battery
receives a pulse when the voltage drops. Keeps the battery in perfect condition when it is not
used. The charger can be connected for months at a time. If possible, check the water level in
the battery.
TEMPERATURE PROTECTION
M300 STARTER 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
M300 STARTER is delivered with a set of battery leads with battery pole clamps and a set of
battery leads with eyelet terminals.

Type of batteries All types of 12V lead-acid batteries (Wet, MF, VRLA,
AGM and GEL).
Battery capacity 1.2–32Ah, up to 100Ah for maintenance.

*) Back Current Drain is what the charger uses to drain the battery if the power cord is
disconnected.
**) Quality of the current and voltage are very important. High current ripple heats up the
battery and makes the positive electrode age prematurely. High voltage ripple could harm
other equipment connected to the battery. M300 STARTER produces a high quality current and
voltage with very low ripple.
***) If the power connected is the flat European contact type, the battery charger has insulation
class IP63, except in Switzerland where IP65 is valid.
