PLATES
(Electrodes)
Plate construction
is the key to producing a good battery. Recognizing
this, 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 oxide paste is added to the grid to
form the electrically active material. In the charged
state, the negative plate paste is pure lead and that of
the positive lead oxide. 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 unparalleled
recovery from deep discharge
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.
ELECTROLYTE
Immobilized dilute
sulfuric acid: H2S04.
CONTAINER
Case material is
non conductive ABS plastic to UL94-HB with high
resistance to chemicals and flammability. Certain models
are offered with a flame retardent (FR) case and lid to
UL-94 V-O
LEAKPROOF DESIGN
& OPERATIONAL SAFETY
Power-Sonic batteries have been approved
for shipment by air, both by D.O.T. and I.A.T.A.. U.L's
component recognition program for emergency lighting and
power batteries lists POWER-SONIC under file numbers
MH20845 and MH14838.
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.
RELIEF VALVE
In case of
excessive gas pressure build-up inside the battery
(usually caused by abnormal charging) 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.
CASE SEALING
Depending on the
model the case sealing is ultrasonic welded, epoxy, or
heat seal.
