Powersonic Psh12180Fr 12 Volt 21Amp/Hr Batt

Power-Sonic 12V 21Ah Sealed Lead Acid Battery

• <b>Sealed/Maintenance-Free</b> - 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
• <b>Valve Regulated Design</b> - 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.
• <b>Design Flexibility</b> - 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.
• <b>Rugged Construction</b> - 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.
• <b>Wide Operating Temperature Range</b> - 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)
