What is a GEL Battery?


Two of the most common terms that we hear from customers are AGM and GEL, which are often mistaken for the other more than half the time. We have already explained what exactly an AGM battery is, now we will be taking a look into what sets a true GEL battery apart from the rest of the sealed lead acid pack.

Okay, first and foremost, the term GEL is short for gelified electrolyte lead acid. In other words, a true GEL battery will actually contain a gelatin in place of the typical free flowing electrolyte (battery acid).  A special gelling agent is added to the electrolyte to reduce the movement of acid inside of the battery – the process literally turns the acid mixture into a gooey Jell-O like substance. Due to this mixture of Jell-O like acid, the GEL battery is designed with special one way safety valves in place of open vents typically found on wet-cell batteries (non-sealed), this method of venting allows the internal gasses to recombine back into water in the battery, greatly reducing gassing.


Is the GEL Battery Sealed?


Yes, the GEL battery is a sealed non-spillable type. If the casing of the battery were to develop cracks or otherwise be compromised, there will be no free flowing acid leaking out the of the battery. 


Is it Maintenance Free?


Yes, the GEL battery is also a maintenance free type. The term battery maintenance typically refers to the need to check on the electrolyte level of the battery about every thirty to sixty days depending upon usage. The valve system used in both AGM and GEL applications minimizes the amount of electrolyte released from the battery during the charging period.


What is a GEL battery used in?


The GEL style battery is used in wide variety of deep-cycle applications due to their ability to recover from deep discharge cycles. Where the GEL battery will excel is in situations that require a slow and steady discharge. A prime example of a good application for a GEL battery would be an electric mobility chair.
