Material tested data
Power-Sonic has always strived to deliver the highest quality product to it’s over 3,000 customers. Stringent process controls govern all manufacturing activities. Quality engineers are highly involved in evaluating the quality and reliability of all products manufactured both in the design and production stages. Our quality controls are emphasized throughout our manufacturing process to maximize customer satisfaction. The following is a list of tests our products go through to ensure quality.

CAPACITY TEST
Batteries are discharged at the 0.3C rate. After 120 minutes of continuous discharge the battery voltage under load must be 1.75 volt/cell to pass (C = rated capacity of a battery; e.g. PS-610 (6 V, 1 AH) C = 1 amp.



HIGH LOAD TEST
A load of 2 C amps is applied for 5 seconds while the terminal voltage is monitored. To pass, the voltage must be 1.75 volt/cell or higher



VISUAL INSPECTION
Batteries are inspected for proper appearance of battery case, terminals, seals, markings, and the absence of electrolyte leakage. Several samples each day are checked for compliance with specified dimensions and tolerances.



CAPACITY TEST - MEDIUM LOAD
Samples are fully charged, then discharged at room temperature at the 0.2C rate to a final voltage of 1.7 volt/cell. The discharge time must be no less than 4 hours.



CAPACITY TEST - HIGH LOAD
Fully charged batteries are discharged at 77 ºF (25 ºC) at the 2C rate to an end voltage of 1.35V/cell. The expected discharge time is 12 minutes.



SHELF LIFE TEST
Fully charged batteries are stored for 2 1/2 weeks at 131 ºF (55 ºC). A discharge test performed at room temperature applying a load of 0.2C rate to 1.7V/cell must yield a run time of at least 2 hours, i.e. the capacity loss resulting from self discharge must not exceed 50%.



VIBRATION TEST
Sample batteries are subjected to vibrations in any direction at the rate of 2000 cycles per minute and amplitude of 0.1 in (2.5mm) for 2 hours. No signs of damage, leakage, or change in electrical characteristics are expected.



OVERCHARGE TEST
Fully charged batteries are overcharged at the rate of 0.1C amps for 48 hours and then allowed to rest for 2 hours. Discharging the batteries at the 0.1C rate to 1.75 volt/cell is expected to produce a run time of 8.5 hours, or at least 95% of initial capacity, and an absence of problem signs.



RELIEF VALVE TEST (UL924)
A fully charged battery is submerged in a tank filled with mineral oil and charged at 0.4C amps. This overcharge is to demonstrate the proper functioning of the safety relief valve. The release of excess gasses through the vent is demonstrated by bubbles rising from the battery.



CYCLE LIFE TEST
At an ambient temperature of 77 ºF (25 ºC) sample batteries are discharged at the 0.2C rate to 1.7V/cell and recharged at the 0.25 rate up to 2.5V/cell until charge current drops to 0.01C amps. At least 175 cycles must be obtained before the capacity drops below 60% of initial capacity.



 Features and benefits

SEALED MAINTENANCE FREE
The valve regulated, spill-proof construction of the POWER-SONIC battery allows trouble-free, safe operation in any position. There is no need to add electrolyte, as gases generated during charging are recombined in a unique "oxygen cycle".



EASY HANDLING
No special handling precautions or shipping containers - surface or air - are required due to the leak-proof construction.



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.



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.



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 50 models are available to choose from.



RUGGED CONSTRUCTION
The high-impact resistant battery case is made either of non-conductive ABS plastic or styrene. Large capacity batteries frequently have polypropylene cases; all of these materials impart great resistance to shock, vibration, chemicals and heat.



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 provides superior power/volume and power/weight ratios.



HIGH DISCHARGE RATE
Low internal resistance allows discharge currents of up to ten times the rated capacity of the battery. Relatively small batteries may thus be specified in applications requiring high peak currents.



LONG SHELF LIFE
A low self-discharge rate may allow storage of fully charged batteries for up to a year at room temperature before charging is required. Lower storage temperatures enhance shelf life characteristics even further.



WIDE OPERATING TEMPERATURE RANGE
Power-Sonic batteries may be discharged over a temperature range of -40 ºC to +60 ºC (-40 ºF to +140 ºF), and charged at temperatures ranging from -20 ºC to +50 ºC (4 ºF to +122 ºF).



DEEP DISCHARGE RECOVERY
Special separators, advanced plate composition, and a carefully balanced electrolyte system have greatly improved the ability of recovering from excessively deep discharge.
