A calculation example is shown below:
A 200 Ah battery is discharged with a constant current of 20 A and
after 8.5 hours 1.75 V/cell is reached.

2.3.3 Charged-parameters
Based on increasing charge voltage and decreasing charge current, a
decision can be made whether the battery is fully charged or not.
When the battery voltage is above a certain level during a predefined
period while the charge current is below a certain level for the same
period, the battery can be considered fully charged. These voltage and
current levels, as well as the predefined period are called 'charged-
parameters'. In general for a 12 V lead acid battery, the voltage-
charged-parameter is 13.2 V and the current-charged-parameter is
4.0 % of the total battery capacity (e.g. 8 A with a 200 Ah battery). A
charged-parameter-time of 4 minutes is sufficient for most battery
systems. Please note that these parameters are very important for
correct operation of your BMV, and must be set appropriately in the
corresponding menu items.
