Preventing damage due to excessive gassing: the BatterySafe mode
If, in order to quickly charge a battery, a high charge current in combination with a high
absorption voltage has been chosen, the Multi Compact / MultiPlus Compact will prevent
damage due to excessive gassing by automatically limiting the rate of voltage increase once
the gassing voltage has been reached.
Less maintenance and aging when the battery is not in use: the Storage mode
The storage mode kicks in whenever the battery has not been subjected to discharge during
24 hours. In the storage mode float voltage is reduced to 2,2 V/cell (13,2 V for a 12 V battery)
to minimize gassing and corrosion of the positive plates. Once a week the voltage is raised
back to the absorption level to 'equalize' the battery. This feature prevents stratification of the
electrolyte and sulphation, a major cause of early battery failure.
Two outputs to charge 2 battery banks
The Multi Compact / MultiPlus Compact features 2 outputs, of which 1 can carry the full
output current. The second output, limited to approximately 4A and with a slightly lower
output voltage, is intended to top up a starter battery.
To increase battery life: temperature compensation
Every Multi Compact / MultiPlus Compact comes with a battery temperature sensor. When
connected, charge voltage will automatically decrease with increasing battery temperature.
This feature is especially recommended for sealed batteries and/or when important
fluctuations of battery temperature are expected.
