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 elecrolyte, 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 the leak-proof construction.

The high watt-hour per dollar value is made possible by the materials used in a seal 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 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 40 models are available to choose from.
