6FM75TD-X
12V 75Ah(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 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.
