The rechargeable batteries are lead-lead dioxide systems. The dilute sulfuric acid electrolyteis 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
