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.
6. If the charger lamp and the maintenance-charger lamp are flashing 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 flash for more than 30 minutes, this indicates that the battery is dead and
needs to be replaced.
• If there is an interval of more than 10 seconds between the flashes, 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.
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 sent 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.

*) 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. M45 produces a high
quality current and voltage with very low ripple.
BULK CHARGING TIME
The table shows the length of time for bulk charging.
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.
