HOPPECKE grid | power V L 2-1150 OPzS Cell 2 V 1140 Ah

grid | power V L 2-1150 is a 2 V tubular-plate OPzS cell of the HOPPECKE grid | power V L series, DIN designation 10 OPzS 1000. The brochure lists 1140 Ah at C10 to 1.80 V per cell, 76.4 kg and a maximum size of 215 x 235 x 710 mm.

An OPzS tubular-plate cell for long-life telecom and power supply batteries

The V L series is HOPPECKE vented OPzS: positive tubular plates in a low-antimony selenium alloy that give a very long expected service life and excellent cycle stability, with dimensions to DIN 40736-1. System connectors raise short-circuit safety while the cells are being installed.

The 2-1150 is the ten-plate cell with a nominal 1000 Ah class (10 OPzS 1000) but a real C10 capacity of 1140 Ah. The brochure shows it in Figure B, with a maximum width of 235 mm and the same 710 mm height as the 2-1035 and 2-1265 beside it.

Benefits listed in the brochure

• Low-antimony selenium alloy and tubular plate design: very high expected service life, up to 20 years, and excellent cycle stability.
• DIN 40736-1 design for maximum compatibility with existing OPzS installations.
• Optional grid | AquaGen recombination system: water refill intervals up to maintenance-free, with less gas and aerosol emission than usual vented cells.

Choosing within V L and power.bloc OPzS

The OPzS table runs from 2-215 (4 OPzS 200, 213 Ah, 105 x 208 x 420 mm) to 2-3500 (26 OPzS 3250, 3488 Ah, 229.6 kg, 215 x 580 x 815 mm), with figures A to D by size. Separate power.bloc OPzS monoblocs cover 12-50, 12-100, 12-150 and 6-200 to 6-300, built to DIN 40737-3.

Pick by discharge duration from the C-rate columns and not by the DIN name alone, then confirm the code and plug type before ordering.

Installation and operating points from the manual

Battery rooms need ventilation that keeps hydrogen below 4 percent by volume; the manual gives the air flow as Q = 0.05 x n x I_gas x C / 1000 Ah, with a dilution factor of 24 and a safety factor of 5. The floor must carry the load, resist electrolyte, and be reasonably conductive.

Standby parallel float is 2.23 V per cell, with temperature compensation of minus 4 mV per kelvin away from 20 °C. Operating temperature of vented cells is allowed from -20 °C to +40 °C but should be held at 20 °C plus or minus 5 K for life; 55 °C must never be exceeded.

Telecom stations, off-grid power and security lighting

The brochure names telecommunications (mobile phone and BTS stations, off-grid and on-grid), power supply systems and security lighting. General engineering note: remote and off-grid Gulf sites make site visits expensive, so a long-life design life and the optional AquaGen plug, which stretches water refill intervals, are the points to weigh when shortlisting this cell.
