CP1272
12V 7.2Ah(20hr)
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.
