12V Solar Wind AGM Deep Cycle Battery
NPD7-12 (12V7Ah/10hr)?The rechargeable batteries are lead-lead dioxide systems. The dilute sulfuric acid electrolyte is absorbed by separators and thus immobilized.?Should the battery be accidentally overcharged producing bydrogen and oxygen, Special?one-way valves allow the gases to escape thus avoiding excessive pressure build-up. Otherwise, the battery is completely sealed and is, therefore, maintenance-free, leak proof and usable in any position.Battery ConstructionComponentPositive plateNegative plateContainerCoverSafety ValveTerminalSeparatorElectrolyteRaw materialLead DioxideLeadABSABSRubberCopperFiberglassSulfuric AcidGeneral Feature?Absorbent Glass Mat(AGM) technology for efficient gas recombination of up to 99% and freedom from electrolyte maintenance or water adding.?Not restricted for air transport-complies with IATA/ICAO Special Provision A67.?UL-recognized component.?Can be mounted in any orientation. Computer designed lead, calcium tin alloy grid for high power density.?Long service life, float or cyclic applications.?Maintenance-free operation.?Low self discharge.SPECIFICATIONNominal voltage----------------------12VNumber of cell ----------------------- 6Length(mm/inch)----------------------- 151/5.94Width(mm/inch) --------------------------- 65/2.56Height(mm/inch)--------------------------- 93/3.66Total Height(mm/inch) ------------------- 100/3.94Approx.
