SHENZHEN LEADHOO BATTERY CO.,LTD

NP24-12 (12V24Ah/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.
