Charging
The M300 charges and analyses in eight fully automatic steps
» Desulphation
Desulphation with pulsing for sulphated batteries.
» Start
Starting phase for charging. The starting phase continues until the battery's terminal voltage has risen over a preset level. At this point, charging goes into the bulk phase. If the terminal voltage has not reached the preset level within a preset time, charging is suspended. The error mode is indicated. This indicates a battery which is faulty or has too large capacity. If a large battery is charged that has been severely discharged, it may be necessary to restart the charger after a preset time.
» Bulk
Primary charging where approximately 80 percent of the charging takes place. The charger delivers maximum current until the terminal voltage has risen to the preset level. After a number of hours, the charger goes on to the next phase, even if maximum voltage is not reached.
» Absorption
Final charging, voltage is kept at the preset level. During this phase, the current is gradually reduced. If the maximum length of time for Absorption is exceeded, the charger automatically continues with Analysis.
» Analysis
Charging is suspended for a short period and the battery voltage measured. If it falls too quickly, the battery is probably faulty. Charging is suspended and an error is indicated.
» Recond
Recond is used to recover severely discharged flooded batteries and for reconditioning severely discharged batteries suffering from stratification. The voltage increases with reduced current for a limited time period (depending on the charge level of the battery at start). The higher voltage starts some gassing and mixing of the acid, which is beneficial for both battery capacity and expected life. The battery could emit explosive gas during this step.
» Maintenance charging float
During the first 10 days of maintenance charging the battery is maintained with constant voltage.
» Maintenance charging pulse
State of charge varies between 95 percent and 100 percent. The battery receives a pulse when the voltage sinks, keeping the battery in good shape when it is not being used. The charger can be connected for months at a time. If the battery is charged and/or the battery's terminal voltage drops, the charger starts a charge pulse until the voltage has reached the preset level. The charge pulse is then interrupted and the cycle is repeated as long as the charger is in pulse maintenance phase. If the terminal voltage drops even lower, the charger automatically reverts to the beginning of the charging curve. If possible, check the water level in the battery.
Using the M300 gives your battery an optimum service life and operational reliability.
Batteries
The M300 can be set very easily to charge different types of leadacid batteries (Wet, MF, GEL, Calcium/Calcium and AGM) and conditions.
The M300 charges a wide range of battery sizes, from 50Ah to 500Ah.
Temperature
To protect the charger from overheating, the M300 is fitted with power limitation. The power reduces when the ambient temperature increases. The power also reduces if the charger were to be covered, which protects the charger from damage. The charger continues to work, but at a lower output. When the ambient temperature drops, the power automatically increases again.

) Back current drain is what drains the battery if the charger is connected without the power cord connected.
) Ripple denotes the amount of interference there is to the current and voltage. A high current ripple heats the battery and shortens its life. A linear charger has a current ripple of 70 400 percent which is much larger than the maximum 5 percent for a modern sealed battery. Voltage ripple could harm other equipment, which is connected to the battery.
The M300 delivers voltage and current with very low ripple. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery.
) IP 44 cannot be guaranteed unless the charger is positioned with its top or long side facing up.
For the technical data of the M300 starter, please see the XS800.
Mounting
The charger is easily fitted in place using four screws. The diameter of the mounting holes is 4.5mm.
The charger must be fitted with the top or long side facing up to be approved for outdoor use.
The mounting instructions for the M300 starter are the same as for the XS800.
Equipment
The M300 is delivered with a battery lead with eyelet terminals.
The charger also has a sensor cable located together with the battery leads. The unit automatically adjusts the charge voltage if the temperature deviates from +25 Degrees C. Higher temperatures lower the voltage and lower temperatures raise the voltage. The sensor cable can be extended or shortened without affecting functionality.
Provided with the M300 is also the M300 starter. The M300 starter is basically a XS800
