Overview
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.
