Battery - AGM Battery - ARGO (Yuasa)
The battery is located under the hood on
the right hand side of the vehicle at the
dash (intake side of vehicle)
AGM batteries look dierent than other battery types. They are more compact because
there is no free electrolyte making them more “volume ecient” in that they take up less
space for their energy storing capacity. Because they are lled with electrolyte only one
time during activation there are no ller caps. Instead a sealing plug permanently covers
the ller ports. Also there is no vent tube. AGM batteries are ideal for long term storage.
In addition, an AGM battery is an excellent choice for use in vehicles where acid spills
could occur (atv’s etc.).
Activating and Charging AGM Batteries
Activating an AGM battery is a simple process and diers from activating a
Conventional battery. Un-activated, AGM batteries can be stored for long periods of
time as long as they are kept in a cool, dry location and out of direct sunlight. Also
the foil sealing strip covering the ller ports should not be removed until the battery is
ready to be activated. Use only the electrolyte container that comes with the battery for
lling the cells as it has a higher concentration of sulfuric acid than the acid used for
Conventional batteries.
The electrolyte container that is shipped with a dry AGM battery
contains the correct amount of battery acid and
is more concentrated than the electrolyte used in a conventional
battery. All AGM battery electrolyte containers are not the same.
Each contains the proper amount of electrolyte for its specic
battery.
Before lling, read the electrolyte handling instructions and precautions on the label.
Do not smoke when activating a battery or handling battery acid. Always wear plastic
gloves and protective eyewear and be sure to read the Battery Safety section that
comes with your battery. The following seven steps should be used to activate an AGM
battery:
