Sealed/Maintenance-Free - The valve regulated, spill-proof construction of our batteries allows trouble-Âfree, safe operation in any position. There is no need to add electrolyte.
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.
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.
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.
Wide Operating Temperature Range - Power-Sonic batteries may be discharged over a temperature range of -40C to +60C (-40F to +140F) and charged at temperatures ranging from -40C to +50C (-40F to +122F)
The Power-Sonic valve regulated sealed lead acid batteries are maintenance free, easy to handle, rugged and economical. It has a characteristic of high discharge rate, wide operating temperature, long service life and deep discharge recover.Key FeaturesAbsorbent Glass Mat (AGM) technology for superior performance.Valve regulated, spill proof construction allows safe operation in any position.Power/volume ratio yielding unrivaled energy density.Approved for transport by air. D.O.T., I.A.T.A., F.A.A. and C.A.B. certified.U.L. recognized under file number MH 20845. PRODUCT FEATURESSEALED 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.

My Bachmann G gauge Shay locomotive has a sound system which starting operating strangely at low speeds. As the loco has a battery to allow sound at low rail voltage I took a chance the 6 year old battery had failed. Just received and installed the new Power-Sonic PS605WL, which was an exact replacement and all is well. So any modelers out there, look to your battery first for low voltage sound problems.
Exact replacement in my Snap On/Sun LS2000 Digital Oscilloscope. Last long, charges quickly.
