- Sealed/Maintenance-Free - The valve regulated, spill-proof construction allows troublefree, safe operation in any position. There is no need to add electrolyte, as gases generated during overcharge are recombined in a unique "oxygen cycle."
- Valve Regulated Design - Our batteries incorporate a series of one-way low pressure valves. These self sealing valves allow the enting of any excess gasses that may be produced in the battery due to severe overcharging. Valve regulated batteries should n
- 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 60 models are available to choos
- 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/covers to
- 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)
