Absorbed Glass Mat Series AGM Battery Brochure

Deka’s AGM (Absorbed Glass Mat) Series uses a special absorbed
electrolyte technology that is superior to conventional lead-acid batteries.
This completely sealed valve-regulated battery line eliminates gas emissions
and acid leakage for longer and safer battery operation.
How AGM Works
Unlike conventional “flooded” lead-acid batteries, AGM sealed valve-regulat-
ed technology eliminates the need to add water because the oxygen and
hydrogen gases react to maintain the necessary amounts of moisture. Highly
porous microfiber separators wrapped around the positive plates completely
absorb and trap the electrolyte,
so there is no excess to spill or
leak out of the battery. Oxygen
formed from the positive plates
during charging passes hori-
zontally through the separator
pores to the negative plates,
where it reacts with hydrogen
and changes back to water to
replenish the electrolyte.

ABSORBED GLASS MAT SERIES
AGM Features – The extremely efficient
design includes several unique features.
■ Specially-engineered safety relief valve
system effectively controls critical inter-
nal gas pressure, preventing capacity loss
from excessive gas seepage. This one-way
valve also prevents outside air from entering
the battery–a common cause of failure in
most sealed valve-regulated battery designs.
■ Fine microfiber glass separators are
highly porous to hold electrolyte more
efficiently and have extremely low electrical
resistance for higher capacity.
■ Power path grids are computer-cast and
pasted to uniform thickness, allowing for
the exact degree of compression needed for
optimum oxygen flow between the plates and
separators. (Plates compressed too tightly
will impede oxygen flow, while plates packed
too loosely allow valuable oxygen to escape
to the top of the battery. Both conditions
seriously impair performance and shorten
battery life.)
■ Exclusive individual tank formed plates
provide the highest quality and most consis-
tent performance.
■ Rated non-spillable by ICAO
(International
Commercial Airline Organization)
, IATA (Inter-
national Airline Transport Association)
and DOT
(Department of Transportation) definitions.
AGM Benefits – The AGM Series offers
all the advantages of conventional “flooded”
batteries without the disadvantages.
■ Maintenance-free construction eliminates
the need to add water.
■ Completely sealed valve-regulated design
eliminates acid spills and terminal corrosion.
■ Safer operation substantially minimizes
chance of acid spray, fumes and explosion
hazards when charged correctly.
■ Flexible design can be installed in almost
any position. (However, upside-down
installation is not recommended.)
■ State-of-charge easily determined
by open circuit voltage.
■ Lower electrical resistance provides
higher discharge rates.
■ High freeze-resistance offers longer
battery life.
■ Resists vibration damage for longer
operating time.
■ Lightweight construction for
easy installation.
■ Requires less charging time than
conventional batteries.
