Positive plates
Positive plates are plate electrodes of which a grid
frame of lead-tin-calcium alloy holds porous lead
dioxide as the active material.

Electrolyte
Diluted sulfuric acid is used as the medium for
conducting ions in the electrochemical reaction in the
battery.

Separators
The advanced micro porous Absorbed Glass Mat
(AGM) separators retain electrolyte and prevent
shorting between positive and negative plates.
Separators adopt a non-woven fabric of fine glass
fibers which is chemically stable in the diluted sulfuric
acid electrolyte. Being highly porous, separators
retain electrolyte for the reaction of active materials in
the plates.

Valve (One way valve)
The valve is comprised of a one-way valve made of
material such as neoprene. When gas is generated
in the battery under extreme overcharge conditions
due to erroneous charging, charger malfunctions or
other abnormalities, the vent valve opens to release
excessive pressure in the battery and maintain the
gas pressure within specific range (7.1 to 43.6 kPa).
“The vent helps protect the battery from the danger of
bursting. Since the rubber valve is instantly
resealable, the valve can perform this function
repeatedly whenever required.”

During ordinary use of the battery, the vent valve is
closed to shut out outside air and prevent oxygen in
the air from reacting with the active material in the
negative electrodes.

Positive and negative electrode terminals
Positive and negative electrode terminals may be
faston tab type, bolt fastening type, threaded post
type, or lead wire type, depending on the type of the
battery. Sealing of the terminal is achieved by a
structure which secures long adhesive-embedded
paths and by the adoption of strong epoxy adhesives.
For specific dimensions and shapes of terminals,
refer to the terminal dimensions page in the back of
the technical handbook.
