The Power-Sonic PS-1270 F1 valve regulated sealed lead acid battery is maintenance free, easy to handle, rugged and economical. It has a wide operating temperature, long service life under ideal working conditions, high discharge rate, and deep discharge recovery.Absorbent Glass Mat (AGM) technology for superior performance.Valve regulated, spill proof construction allows safe operation in any position.Power/volume ratio yielding unrivaled energy density.Approved for transport by air. D.O.T., I.A.T.A., F.A.A. and C.A.B. certified.U.L. recognized under file number MH 20845Sealed maintenance free - valve regulated, spill-proof constructionSafe operation in any positionNo need to add electrolyte, as gases generated during charging are recombined in a unique "oxygen cycle" Long Service Life - Under normal operating conditions, four or five years of dependable service life can be expected in stand-by applications, or between 200 and 1000 charge/discharge cycles depending on the average depth of discharge.
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.
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: H2SO4.
CONTAINER - Case material is ABS, high-impact plastic resin, styrene, or a polypropylene-polyethylene co-polymer with high resistance to chemicals and flammability.
LEAK-PROOF 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 MH14328 and MH14838.
TERMINALS - Depending on 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 model the case sealing is ultrasonic welded, epoxy, or heat seal
