EFB, or Enhanced flooded Battery technology. EFB battery is based on the traditional battery technology, by adjusting the active substance formula to improve the deep cycle performance of the battery. In addition, the enhanced internal pole group assembly strength allows the battery to improve life while having stronger seismic performance.
AGM, or adsorbent-glass-Mat battery. AGM battery adopts lean liquid design, the plate is not soaked in the electrolyte, in addition to the plate internal absorption of a part of the electrolyte, most of the electrolyte adsorbed on the porous glass fiber separator, and the use of tight assembly technology, so that the plate fully contact the electrolyte.
VRLA batteries are valve-controlled sealed lead-acid batteries(Valve Regulated Lead Acid Battery).Because VRLA battery is fully sealed, will not leak acid, and in charge and discharge will not be like the old lead-acid battery will have acid mist released and corrosion equipment, pollution of the environment, so from the structural characteristics of the VRLA battery is also called closed (sealed) lead-acid battery.
