execute a complete four stage charging process again, once the battery load consumption
has dropped below the charger's maximum output current level.
When the Mode is set to 2, no Float stage is entered so the battery is not being maintained.
However, also in this Mode the charger will automatically restart the charging process when
the voltage of the connected battery has dropped below the restart voltage.
Summary of charge progress indicator steps:
Gel, AGM, Flooded:
The fourth stage called "Pulse", will perform a short refresh charge of approximately 1 hour
each 7 days while the charger operates in the Float or Stop stage. This will keep the battery
in optimal condition while prolonging it's lifetime. The battery can remain connected to the
activated charger continuously, without risk of overcharging.
When the battery temperature sensor (BTS) is installed, the charger automatically
compensates the charge voltage against battery temperature. This means that the charge
voltages are slightly increased at lower temperatures and decreased at higher temperatures.
Please see the table below for the compensation amounts:
Battery temperature
< 25°C
25°C
> 25°C
There is no charge voltage compensation for lithium battery types.
A connected BTS also enables battery temperature protection, which stops the charging
process when the battery's temperature is below -20°C (0°C for Lithium) or above +55°C.
When the BTS is not in use, you can also manually set the battery temperature. There are
three settings available (T.NO, T.HI and T.LO). Please see the next table below for the voltage
adjustment values compensated from the normal 25°C setting:
