These Vision batteries are internally constructed with AGM (Absorbed Glass Material) Technology resulting in a very efficient, fully sealed, valve regulated battery. 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.
FEATURES: Absorbent Glass Mat (AGM) technology for efficient gas recombination of up to 99% and freedom from electrolyte maintenance or water adding. Not restricted for air transport-complies with IATA/ICAO Special Provision A67. Can be mounted in any orientation. Computer designed lead, calcium tin alloy grid for high power density. Long service life, float or cyclic applications. Maintenance-free operation. Low self discharge.
