• 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
• 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)

havent had to jumpstart anything yet; but since installing this battery in my universal power ,jumpstarter and compressor box; everthing works better than when it was new . this battery is much heavier than the old one which means there is more plates than the original battery which means more and better power

I order two Powersonic PS-12180NB batteries sold by eComElectronics on Amazon. What they sent me were two ub12180 from another manufacturer (which can be bought cheaper on eBay). The batteries charged and seemed to be working fine but after the first charge neither battery would charge in the device I bought it for nor would they charge out of the device on a battery charger. I notified eComElectronics and they did not respond. Complete waste of money and not even the product advertised.

I needed a battery to replace the one in my Wagan Power Dome. This fit exactly and brought the runtimes on my inverter from 1 hour to over 9 hours on a 20 watt led TV load. It also delivers lots of amps for jump starting. Great!
