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 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
