12V AGM Rechargeable Battery Pack
NP12-12 (12V12Ah/20hr) 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 voltageVNumber of cell 6Length(mm/inch 151/5.94Width(mm/inch) 98/3.86Height(mm/inch 95/3.74 Total Height(mm/inch) 101/3.98 Approx.
