2 Engineered With Vision. Built With Care. Power-Sonic has more than 38 years of battery industry experience and today our batteries are sold in more than 7 countries world-wide. Since our inception in 197, our focus has been the design, manufacture and marketing of rechargeable batteries, specifically: Sealed lead-acid (SLA), also called valve regulated leadacid (VRLA) batteries Powersport batteries Sealed nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries NiCd and NiMH configured packs (cell assemblies) SLA battery chargers NiCd and NiMH battery chargers Our products are widely used in an ever broadening range of electronic and industrial applications. Our batteries continue to be used wherever cost effective and reliable DC power is required, be it as the principal power or standby power source. Our aim is the ongoing improvement of our existing products, coupled with the development of new tailored products, to meet the ever increasing needs for stand alone power. Our advanced engineering techniques and state-of-the-art manufacturing processes ensure that we remain on the cutting edge of battery technology. These skills, coupled with our selection of the finest raw materials, allow us to produce batteries combining superior performance and value. Providing our customers with reliable, yet economical, products is the cornerstone of our mission. Features Sealed/Maintenance-Free The valve regulated, spill-proof construction allows troublefree, safe operation in any position. There is no need to add electrolyte, as gases generated during overcharge are recombined in a unique oxygen cycle. Valve Regulated Design Our batteries incorporate a series of one-way low pressure valves. These self sealing valves allow the venting of any excess gasses that may be produced in the battery due to severe overcharging. Valve regulated batteries should never be recharged inside a sealed container. Design Flexibility Batteries may be used in series and/or parallel to obtain choice of voltage and capacity. Due to recent design breakthroughs, the same battery may be used in either cyclic or standby applications. Over models are available to choose from. Compact Power-Sonic batteries use state-of-the-art design, high grade materials, and a carefully controlled plate-making process to provide excellent output per cell. The high energy density results in superior power/volume and power/weight ratios. Rugged Construction The high impact resistant battery case is made of nonconductive ABS plastic to UL94-HB. This material imparts very good resistance to shock, vibration, chemicals and heat. Certain models feature flame retardant (FR) cases/covers to UL94 V-O. Wide Operating Temperature Range Power-Sonic batteries may be discharged over a temperature range of -4 C to + C (-4 F to +14 F) and charged at temperatures ranging from -4 C to +5 C (-4 F to +122 F). Long Service Life Under normal operating conditions, four or five years of dependable service life can be expected in stand-by applications, or between 2 and 1 charge/ discharge cycles depending on the average depth of discharge. Deep Discharge Recovery Special separators, advanced plate composition, and a carefully balanced electrolyte system have greatly improved the ability to recover from excessively deep discharge. Lead Calcium Plates Heavy duty lead calcium plates provide an extra margin of performance and life in both cyclic and float applications and give unequaled recovery from deep discharge. Economical The high watt-hour per dollar value is made possible by the materials used in a sealed lead-acid battery: they are readily available and low in cost. Operation in any Orientation Our SLA batteries can be discharged in any orientation, without reduction in performance or leakage of electrolyte. High Rate Discharge Low internal resistance allows discharge currents of up to ten times the battery s rated capacity. Relatively small batteries may thus be specified in applications requiring high peak currents. Long Shelf Life A low self discharge rate allows storage of fully charged batteries for extended periods of time before charging is required. Lower storage temperatures further enhance shelf life characteristics. We ve Got The Power.

Capacity increases when the discharge current is less than the 2-hour rate and decreases when the current is higher. The graph above shows capacity curves for major Power-Sonic battery models with different ampere-hour ratings. Amperage is on the horizontal scale and the time elapsed is on the vertical scale; the product of these values is the capacity. Proper selection of the battery for a specific application can be made from this graph if the required time and current are known. For example, to determine the proper capacity of a battery providing 3 amps for 3 minutes, locate the intersection of these values on the graph. The curve immediately above that point represents the battery which will meet the requirement. POWER-SONIC Rechargeable Batteries

Charging before use is necessary to recover full capacity. Charge may fail to restore full capacity. Do not let battery reach this state Storage Period (Months) Temperature ( C) Charging Cycle Applications: Limit initial current to.3c (C is the nominal amp hour capacity of the battery) or 3 amps, which ever is the less. Charge until battery voltage (under charge) reaches 2.45 volts per cell at 8 F (2 C). Hold at 2.45 volts per cell until current drops to approximately.1c ampere. Battery is fully charged under these conditions, and charger should either be disconnected or switched to float voltage. Float or Stand-by Service: Hold battery across constant voltage source of 2.25 to 2.3 volts per cell continuously. When held at this voltage, the battery will seek its own current level and maintain itself in a fully charged condition. Application Notes Continuous over- or undercharging is the single worst enemy of a lead-acid battery. Caution should be exercised to insure that the charger is disconnected after cycle charging, or that the float voltage is set correctly. Because there is a chance of off-gassing hydrogen and oxygen if the battery is overcharged, it is important to provide adequate air circulation. Never charge or discharge a battery in a hermetically sealed enclosure. Batteries should not be stored in a discharged state (or in a hot place). If a battery is discharged for some time it may not readily take a charge. To overcome this, leave the charger connected and the battery should eventually begin to accept a charge. Due to the self-discharge characteristics of this type of battery, it is imperative that they be charged within months of storage, otherwise permanent loss of capacity might occur as a result of sulfation. To prolong shelf life without charging, store batteries at 5 F (1 C) or less. We ve Got The Power.

7 Battery Construction 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, 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- psi; the seal ring material is neoprene rubber. 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 electrically 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 unparalleled recovery from deep discharge Electrolyte Immobilized dilute sulfuric acid: H2S4. 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.
