1: I phase (bulk)
At the beginning of the charging process, the flat battery is charged with a
constant current (100% charge current) until the battery voltage reaches the
charging voltage (see "Technical data" on page 44). The charging current de-
creases when the battery has reached this charging level.
2, 3, 4: U0 phase (absorption)
Now the three-stage absorption charging process (U0 phase) begins, where
the duration depends on the battery. The voltage remains constant (U0). In
the first 2 minutes, the charging of the battery is determined. Then the main
charging phase begins when the battery is fully charged.
Once the battery is completely charged (IBS sensor), or the charging current
is below 1.5 amps for 15 minutes, the U0 phase has finished.
