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
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.
