A valve-regulated lead-acid battery (VRLA battery) sometimes called sealed lead-acid (SLA) or maintenance free battery.

There are three primary types of VRLA batteries, sealed VR wet cell, absorbent glass mat (AGM) and GEL cell. Gel cells add silica dust to the electrolyte, forming a thick putty-like GEL. These are sometimes referred to as "silicone batteries". AGM (absorbent glass mat) batteries feature fiberglass mesh between the battery plates which serves to contain the electrolyte. Both designs offer advantages and disadvantages compared to conventional batteries and sealed VR wet cells, as well as each other.

Key Features :

♦ Rechargeable 12V 10Ah AGM Deep Cycle Battery

♦ Gelled electrolyte made by mixing sulfuric acid with silica fume

♦ The electrolyte is gel like ,immobile and does not leak ,enabling uniform reaction of each part of the plate .
