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.
General Features
● Absorbent Glass Mat (AGM) technology for efficient gas recombination of up to 99% and freedom from electrolyte maintenance or water adding.

● UL-recognized component.
● 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.
