Acid Battery Lead Sealed

GF50-12 (12V50Ah/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)----------------------- 277/10.9Width(mm/inch) --------------------------- 106/4.17Height(mm/inch)--------------------------- 221/8.70Total Height(mm/inch) ------------------- 229/9.02Approx.
