Terminals
Depending on the model, batteries come either
with AMP Faston type terminals made of tin
plated brass, post type terminals of the same
composition with threaded nut and bolt
hardware, or heavy duty flag terminals made of
lead alloy. A special epoxy is used as sealing
material surrounding the terminals.
Plates (electrodes)
Power-Sonic utilizes the latest technology and
equipment to cast grids from a lead-calcium
alloy free of antimony. The small amount of
calcium and tin in the grid alloy imparts
strength to the plate and guarantees durability
even in extensive cycle service. Lead dioxide
paste is added to the grid to form the electri-
cally active material. In the charged state, the
negative plate paste is pure lead and that of
the positive lead dioxide. Both of these are in a
porous or spongy form to optimize surface
area and thereby maximize capacity. The
heavy duty lead calcium alloy grids provide an
extra margin of performance and life in both
cyclic and float applications and give unparal-
leled recovery from deep discharge

Relief valve
In case of excessive gas pressure build-up
inside the battery, the relief valve will open
and relieve the pressure. The one-way valve
not only ensures that no air gets into the
battery where the oxygen would react with
the plates causing internal discharge, but
also represents an important safety device in
the event of excessive overcharge. Vent
release pressure is between 2-6 psi; the seal
ring material is neoprene rubber.
Separators
Power-Sonic separators are made of
non-woven glass fiber cloth with high heat
and oxidation resistance. The material
further offers superior electrolyte absorption
and retaining ability, as well as excellent ion
conductivity.
Container & case sealing
Case and lid material is ABS, high impact,
resin with high resistance to chemicals and
flammability. Case and cover are made of
non-conductive ABS plastic to UL94-HB or
UL94 V-O. Depending on the model the case
sealing is ultrasonic, epoxy or heat seal.
