Constant U characteristic curve for the 1 V variant with factory settings
The trickle charge voltage is defined, and is maintained throughout the entire
charging process.
The charging current is also defined according to the battery capacity (charging
current = battery capacity * charging current factor).
This setting is suitable for back-up operation, e.g. to supply power to vehicles in
exhibition rooms, or for uninterruptible power supplies.

On-off charging characteristic curve for the 1 V variant with factory settings
1. Pre-charging with end-of-charge voltage (only with totally discharged batteries)
. Charging with constant charging current, charging voltage increases
3. Recharging with charging voltage, charging current decreases
4. Trickle charging
