Vision Akkus VISION SOLAR-AKKU 12 V, 50 AH 6FM50DX Hoja De Datos

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.
