Power-Sonic Batteries Australia
Power-Sonic batteries are sealed lead acid (SLA), AGM VRLA, deep cycle gel and lithium iron phosphate (LiFePO4) batteries built for UPS backup, fire, security, medical and standby power, with a range spanning 0.5Ah to over 200Ah in 2V, 4V, 6V and 12V. Indigi Power and Cooling supplies the Power-Sonic range across Australia as part of our critical power business, and can match the right chemistry and capacity to your UPS, alarm panel or off-grid system.
Power-Sonic has been a leading manufacturer of rechargeable batteries since 1970, with products sold in more than 70 countries. The rechargeable range covers valve regulated lead acid (VRLA), commonly called sealed lead acid (SLA), together with deep cycle gel, tubular gel and lithium iron phosphate technologies, plus matched chargers and accessories. Over 60 SLA models are available, so whatever the application there is a battery designed to suit the requirement.
As an Indigenous and Veteran-owned critical power and cooling specialist, Indigi Power and Cooling supplies Power-Sonic batteries alongside our UPS maintenance, installation and server room cooling services. That means you can source the batteries and the engineers who fit and commission them from a single Supply Nation and ICN Gateway registered supplier, backed by hubs in Brisbane, Sydney and Melbourne.

Why choose Power-Sonic AGM VRLA batteries
The entire Power-Sonic AGM VRLA range shares a set of design features that make it a dependable choice for standby and light cyclic duty. The grid below sets out what matters most for critical power buyers.
Sealed and maintenance free
Valve regulated, spill-proof construction allows safe operation in any position. Gases produced during overcharge are recombined through an oxygen cycle, so there is no need to add electrolyte.
Valve regulated safety
One-way low-pressure self-sealing valves vent excess gas during severe overcharge, preventing dangerous expansion of the casing and improving safety.
Deep discharge recovery
Heavy duty lead calcium plates and balanced electrolyte give strong recovery from deep discharge in both cyclic and float applications.
Wide temperature range
Discharge from -40 to +60 degrees Celsius and charge from -40 to +50 degrees Celsius, suiting Australian conditions from Cairns to the alpine south.
Series and parallel flexibility
Batteries can be connected in series and parallel to build the voltage and capacity a system needs, and the same battery suits cyclic or standby use.
Certified and compliant
Approved for air transport with D.O.T., I.A.T.A. and F.A.A. certification, UL recognised, CE certified, and selected models carry VdS and CSIRO ActivFire approval for fire and security use.

Applications
Power-Sonic rechargeable batteries serve as either the prime or standby power source across a broad spectrum of electronic and industrial applications, including:
-
Uninterruptible power supplies for server rooms and data centres. See our UPS maintenance and UPS battery pages.
-
Fire detection and alarm systems, where selected PS models are CSIRO ActivFire listed to AS 1603.4.
-
Security and access control panels, emergency and exit lighting.
-
Medical devices and mobility equipment needing reliable spill-proof power.
-
Off-grid solar and energy storage, where deep cycle gel and tubular gel ranges extend service life.
-
Telecom, utility and signalling standby for air, rail and sea infrastructure.
Service life and expectations
Under normal operating conditions, four or five years of dependable service life can be expected from Power-Sonic SLA batteries in standby applications, or between 200 and 1000 charge and discharge cycles depending on the average depth of discharge. Batteries can be charged and discharged in any orientation except upside down without any reduction in performance. Special separators, advanced plate composition and a balanced electrolyte system improve the ability to recover from excessively deep discharge, which is a common cause of premature failure in cheaper cells. The tubular gel range delivers a cycle life close to three times that of the standard Solar SLA range, making it one of the most economically viable options over the life of an off-grid solar system.

Frequently asked questions
How long do sealed lead acid batteries last?
In standby applications Power-Sonic SLA batteries typically deliver four to five years of dependable service life under normal operating conditions. In cyclic use they last between 200 and 1000 charge and discharge cycles, depending on the average depth of discharge. Cooler operating temperatures and shallow discharge extend life, while heat and deep discharge shorten it.
Can sealed lead acid batteries be mounted on their side?
Yes. Power-Sonic valve regulated SLA batteries are spill-proof and can be operated in any position, including on their side, and can be charged and discharged in any orientation except upside down without any reduction in performance.
Do sealed lead acid batteries need ventilation?
Under normal charging the sealed valve-regulated design recombines gases internally, so heavy ventilation is not required as it is for flooded batteries. Some ventilation is still good practice in enclosed cabinets, because the one-way relief valves can vent a small amount of gas during severe overcharge.
Are sealed lead acid batteries dangerous goods?
Power-Sonic SLA batteries are non-spillable and are approved for transport by air with D.O.T., I.A.T.A. and F.A.A. certification, which makes them straightforward to ship compared with flooded types. Lithium iron phosphate models are subject to separate lithium battery transport rules.
How do I charge a 12V sealed lead acid battery?
Use a charger designed for AGM VRLA batteries set to the manufacturer's recommended float and cyclic voltages. Power-Sonic supplies matched chargers for its range. Avoid overcharging and excessive heat, and avoid deep discharge where possible to preserve cycle life.
Which Power-Sonic battery do I need for my UPS?
Match the voltage, capacity in amp-hours, terminal type and physical dimensions of your existing battery, and the number in series that your UPS requires. If you are unsure, send us your UPS model or the part number printed on the current battery and Indigi Power and Cooling will confirm the correct Power-Sonic equivalent.
