The next generation of AGM batteries has arrived - the Eclipse premium battery range. These batteries are superior for deep cycling, running appliances when camping or caravanning, and are even robust enough for hard hitting 4WD and marine applications.

Eclipse batteries use trusted AGM technology to provide a long lasting battery that is ready to withstand the tough Australian conditions. These batteries are 100% sealed, non-gassing, and maintenance free.

Exceptional innovations that set the Eclipse 280AH apart from all others

Integrated battery voltage meter
Don't let your battery get ruined. The problem with traditional AGMs is managing voltage. Discharging too deeply, overcharging, or storing at an incorrect voltage will lead to a reduction in battery life and performance.

Eclipse solves this problem with the integrated battery voltmeter. You'll always know how long you've got left in your battery, and it's easy to ensure the voltage is in a safe range. A quick glance at your battery in storage is all it takes to know whether a top-up is needed - no hassle or extra equipment required.

Patented life extension pack
All batteries have a lifespan. Over time the chemistry or internal plates degrade, slowly reducing your performance until the battery is unusable. AGMs are efficient and long lasting, but eventually they too age and come to an end.

We have invented a way to turn back the clock. Each Eclipse premium battery has our patented life extension pack built in, boosting the expected total lifespan by up to 50%. The life extension pack is designed to revitalise the battery after 3-4 years of service, with one safe and easy application.

Usage benefits

  • Never run out of power unexpectedly with the integrated battery voltage meter
  • Get a longer battery lifespan with the patented life extension pack
  • Exceptional warranty so you don't have to worry if something ever goes wrong
  • Simple to maintain, just keep it charged after usage
  • Safe for using in enclosed environments such as caravans or vehicles (non gassing)
  • Long lasting design provides years of regular use with appliances
  • Easy to use with a wide range of equipment such as lights, fridges, and solar
  • Durable casing protects you from leaking acid

280AH Batteries

I purchased two of these 280AH batteries last month for my 5th Wheeler, I needed to relocate them into the front boot because of the size and weight of them that would prevent me installing them into the normal location. No worries I just purchased longer cables and attached them to the original terminals and bobs your uncle. Love them.
