- Facts only; source body is not redistributed. 15-page Exide technical data sheet (1,056,049 bytes; PDF created 2024-03-25; no printed date or revision). Reached from https://www.exidegroup.com/eu/en/document/classic-opzs-datasheet. Main table on page 2: nominal capacity C10 to 1.80 Vpc at 20 °C; dimensions are maxima; height includes the installed connector and 'can differ depending on the used vent(s)'; weight includes acid and 'may differ by ±5%'. The separate acid weight is not recorded. Flooded is read from the sheet's liquid electrolyte ('diluted sulphuric acid') and its 'W (wet)' part-number code; the word 'flooded' is not printed. Internal resistance is printed without its method and is not recorded. The constant-current and constant-power discharge tables (pages 4-15) are not transcribed; they are kept for the later lead-acid design work.
