Sealed/Maintenance-Free
The Power-Sonic 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 over-charge are recombined in a unique "oxygen cycle."

Easy Handling
No special handling precautions or shipping containers - surface or air - are required due to leak-proof construction.

Economical
The high watt-hour per dollar value of Power-Sonic batteries 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 for Power-Sonic batteries.

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 Power-Sonic battery 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 for Power-Sonic batteries.

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.

High Discharge Rate
Low internal resistance allows discharge currents of up to ten times the rated capacity of the battery. Relatively small Power-Sonic batteries may thus be specified in applications requiring high peak currents.

Long Shelf Life
A low self-discharge rate permits 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 degrees C to +60 degrees C (-40 degrees F to +140 degrees F) and charged at temperatures ranging from -20 degrees C to +50 degrees C (4 F to +122 F).

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.
