battery must supply this which results in a declining battery voltage. At a certain battery
voltage level, the charger jumps back to the Bulk stage and will finalize a complete four stage
charging process again, once the battery load consumption has dropped below the charger's
maximum output current level.
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 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 is installed, the charger automatically compensates
the charge voltages against battery temperature. This means that the charge voltages are
slightly increased at lower temperatures and decreased at higher temperatures (-30mV/°C
for 12V chargers, -60mV/°C for 24V chargers and -120mV/°C for 48V chargers). This way,
overcharging is prevented which prolongs your battery's lifetime. A connected battery
temperature sensor also enables the battery temperature protection, which stops the
charging process when the battery's temperature is below -20°C or above +50°C.
