The BatteryPlus35 intelligently controlled charging algorithm, automatically sets
charging parameters so that the caravan battery will maintain the best state of
health. The charging modes include:
SOFT START MODE
Charging current is maintained at 10A until the battery voltage reaches 12.3V or
soft start timeout (see table 6) occurs.
BULK MODE
Charging current is maintained at the Bulk current limit until the battery reaches
the Bulk voltage (see table 7), after which charging proceeds to Absorption Mode
ABSORPTION MODE
Battery is charged at Absorption voltage until the current drops below 2A or Bulk-
Absorption timeout occurs.
FLOAT
Charging current is limited to 10A to keep the battery level topped up. Charging
will remain in Float for 6 hours. After Float timeout, the BatteryPlus35 will enter
back into Bulk-Absorption modes.
