Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### What Ritar does differently Ritar is one of the world's largest VRLA battery manufacturers.
