KB12180 12V 18Ah(20hr) - LONG LIFEThe rechargeable batteries are lead-lead dioxide systems. The dilute sulfuric acid electrolyte is absorbed by separators and plates and thus immobilized. Should the battery be accidentally overcharged producing hydrogen 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 Construction
Component Positive plate Negative plate Container Cover Safety valve Terminal Separator ElectrolyteRaw material Lead dioxide Lead ABS ABS Rubber Copper Fiberglass Sulfuric acid
General Features ● Absorbent Glass Mat (AGM) technology
