  CP12120 12V 12Ah(20hr)

Note: This battery is only available in New Zealand

The 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 oneway

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 Electrolyte

Raw material Lead dioxide Lead ABS ABS Rubber Copper Fiberglass Sulfuric acid

General Features
