Both are recombinant batteries. Both are sealed valve-regulated (SVR) – also called valve-regulated lead-acid (VRLA). AGM batteries and gel batteries are both considered "acid-starved". In a gel battery, the electrolyte does not flow like a normal liquid. The electrolyte has the consistency and appearance of petroleum jelly.
Valve Regulated Lead Acid (VRLA) Batteries are sealed maintenance-free lead-acid batteries. The normal lead-acid battery evolves hydrogen which needs to vent through the cell in order to avoid the explosion of the battery. On the other hand, the evolved hydrogen in the VRLA battery is reused in the battery itself.
A valve regulated lead acid (VRLA) battery is a powerful storage unit. It''s both reliable and long-lasting, needing no maintenance. Known also as sealed lead acid (SLA) batteries, they stop gas and fluid leaks using a special valve system. These batteries work in many areas such as deep cycle and for backups.
