PG-SERIES LONG LIFE BATTERIES

Power-Sonic has more than 39 years of battery industry experience and today our batteries are sold in more than 70 countries world-wide. Since our inception in 1970, our focus has been the design, manufacture and marketing of rechargeable batteries, specifically: • Sealed lead-acid (SLA), also called valve regulated lead-acid (VRLA) batteries • Powersport batteries • Sealed nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries • NiCd and NiMH configured packs (cell assemblies) • Battery Chargers Our products are widely used in an ever broadening range of electronic and industrial applications....

PG-Series Batteries Features Sealed/Maintenance-Free Valve-regulated, spill-proof construction allows troublefree, safe operation in any position. The sealed system eliminates electrolyte checking and refilling. Gases generated during charge are recombined in a unique “oxygen cycle”. Long Service Life Thick plate design based on sturdy lead-calcium grids and advanced paste technology provide design lives of up to 10 years in standby applications. AGM Technology Absorbent Glass Mat technology, in tandem with one-way pressure relief valves, result in efficient gas recombination and safety of operation...

Battery Capacity The capacity of a battery is the total amount of electrical energy available from a fully charged cell. Its value depends on the discharge current, the temperature during discharge, the final (cut-off) voltage and the history of the battery. Capacity, expressed in ampere-hours (AH), is the product of the current discharged and the length of discharge time. Battery capacity varies according to the discharge rate being used. Capacity increases when discharge current is less than the 10-hr. rate and decreases when the load current is higher. The rated capacity of a Power-Sonic PG-Series...

Effects of Temperature Actual capacity is a function of ambient temperature and rate of discharge. At 68°F (20°C) rated capacity is 100%. Above this temperature capacity increases, below it capacity decreases as temperature falls. While raising ambient temperatures increases capacity, it also decreases useful service life. It is estimated that battery life is halved for each 18°F (10°C) above normal room temperature. Cyclic Use The number of charge/discharge cycles depends on the capacity taken from the battery - a function of discharge rate and depth of discharge - operating temperature and...

Shelf Life and Storage Special alloy electrodes and high purity lead impart low self-discharge rates and, consequently, a long shelf life. The rate of self-discharge is approximately 3% per month when batteries are stored at 68°F (20°C). At low temperatures it is nearly negligible, at higher ones self-discharge increases. To maximize battery life and performance: • Recharge after each use • Do not store in a discharged state • Store at 68°F (20°C) or lower • Recharge every 6 months if not used Charging Dependable performance and long service life depend upon correct charging. Faulty procedures...

Temperature Compensation Power-Sonic batteries perform well both at low and high temperatures. At low temperatures, however, charge efficiency is reduced; at temperatures above 113°F (45°C), charge efficiency increases so rapidly that there is a danger of thermal runaway if temperature compensation is not precise. The effect of temperature on charge voltage is less critical in float applications than in cyclic use, where relatively high charge currents are applied for the purpose of short recharge times. Temperature effects should definitely be considered when designing or selecting a charging...
