This part contains a summary of abbreviations and terms used in this operation manual:
Battery sealed
The sealed battery contains cells that can not be opened, that allow no refill of water. The cells are
generally closed with space membranes, which open at the first excessive pressure.
These batteries with non-removable fasteners are designated by manufacturers as no maintenance-
free battery with a fixed electrolyte (gel / AGM).
Battery closed
The term “open” battery was replaced by “closed” battery according to DIN-Standard as an “open”
battery has got a degassing stopper.
The term “open” (“vented”) is used quite distinctly on the display and on the printed records.
Final charging- and discharging voltage
The terms charging-/discharging voltage stand for voltages regulated by the manufacturer the range
you can charge / discharge a battery without damage.
Nominal voltage
The nominal voltage is a determined voltage set by battery technology (for example: Lead batteries:
2V/cell; NiCd- batteries: 1,2V/cell) which is drafted as feature size of a battery.
The term „nominal voltage“ is used to calculate a switching voltage (number of cells x voltage) and
within the charging- or discharging programs which are defined for different battery construction
types.
Nominal voltage is not equal to cell voltage!
Nominal capacity
The nominal capacity (Ah) as feature size of a battery is based on a preset discharging at a distinct
temperature upto a set discharging voltage (discharging current, battery temperature, final discharg-
ing voltage).
