What are the differences between gel batteries and absorbed glass mat (AGM) batteries?
Both are recombinant batteries. Both are sealed and valve-regulated and are considered non-spill able and both are considered “acid-starved.” In a gel battery, the electrolyte does not flow like a normal liquid. In AGM batteries all liquid electrolyte is trapped in a sponge-like matted glass fiber separator material. The “acid-starved” condition of gel and AGM batteries protects the plates during heavy deep-discharges. The gel battery is more starved, giving more protection to the plate; therefore, it is better suited for super-deep discharge applications. In high temperature condition, Gel batteries are losing less water than AGM batteries, so Gel batteries more suit high temperature application.
