Opzv batteries benefit from an optimized plate design which gives capacities in excess of the DIN standard values. In addition, this series offers botha longest float life and a high cycle life in widely industrial field.Data sheetCapacity 77°F(25ºC)20hoursrate(22A1.75V)440Ah10hoursrate(42A1.75V)420Ah5hoursrate(75.6A1.75V)378Ah1hourrate(267A1.75V)267AhInternalResistanceFullchargedbattery77°F(25ºC):0.0007ΩCapacityaffectedbyTemperature (10hourrate)104°F(40ºC)102%77°F(25ºC)100%32°F(0ºC)85%5°F(-15ºC)65%Self-Discharge 68°F(20ºC)Capacityafter3monthstorage90%Capacityafter6monthstorage80%Capacityafter12monthstorage60%Maxdischargecurrent77°F(25ºC):2100A(5S)Charge (ConstantVoltage)Float:2.23to2.27V/77°F/(25ºC)Cycle:2.38to2.42V/77°F/(25ºC)MaxCurrent:84ASafety and SealedNo electrolyte leakage will occur from terminals or case or case of any Storace Battery ensuring safe and efficient operation.Maintenance-Free operationThere is no need to add water thanks to unique gas recombination system which totally transforms the generated gas into water.Storace batteries do not need the equalizing chargeAs a result of monomer battery's interface resistance capacity and float voltage uniformity are fine.The special electrolyte retentive separators bold the acid and thus there is no free acid inside the battery, and therefore the battery can be mounted in any position.Long life DesignThe use of heavy -duty lead-calcium alloy grids with anti-corrosive construction enables the Storace AGM battery to remain in float service for 10-15 years; the GEL battery to remain in float service for 15-20 years. The cycle life can be more than 1000 cyclesHigh Reliability and stable qualityWith advancing AGM and GEL production technology and strictly quality control system, the battery quality is stable and the battery performance is reliable. The voltage, capacity and seal are 100% tested on line.Self-dischargeThe self-discharge rate in room temperature is approximately 2% of nominal Capacity per month.Operating temperatureTheStorace Battery can be operated between -40°C to +65°C.The battery can give out over40% fo nominal capacity at -40°C.
