Permanent boost-charge
In some cases, for example when the battery is almost empty, it is recommended to
permanent boost-charge the battery for 10 hours. Do not permanently boost-charge
sealed lead-acid batteries. Contact your Victron Energy dealer or battery dealer for more
information on charging the battery.
To set the charger into the permanent boost-charge mode :
Place the DIP switch number 8 “R boost” to the left. In this mode
the battery is being charged to the boost voltage.
Do not permanent boost-charge the battery for longer than 10
hours as this can cause long term gas formation in the battery and
will damage the battery.
While a battery is being boost-charged, check the water level of
the battery frequently and if necessary add distilled water to the
battery.
4.2
Adjusting the charge voltage
The battery charger has a factory set float and boost voltage. The boost-voltage is always
higher than the float-voltage. These charging voltages are the recommended values
from almost every battery manufacturer. Before adjusting the charge voltage disconnect
the temperature sensor and/or the voltage sense wires.
To change the float-voltage:
Remove all batteries and other users that are connected to the
output of the battery charger.
Plug the AC plug into the mains and switch on the charger.
Place DIP-switches 7 “Eq2” and 6 “Eq1” to the left position, this will
reduce the equalize time to 0 hours. The charger switches into the
float-charge mode.
Place DIP-switch 4 “fine” to the left position in order to accurately
adjust the output voltage.
Measure the float-voltage on the charger output by using a precision
voltage meter.
Adjust the float-voltage by turning the “V float” potentiometer until
the recommended voltage is reached.
Correct the equalize time by moving DIP-switch 7 “Eq2” and 6 “Eq1”.
Place DIP-switch 4 “fine” to the right position. In this position the
output voltage is less sensitive to influence of temperature.
