Description
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.
