Key Features

  • Integrated voltage meter keeps track of how much power your battery has left
  • Patented life extension pack boosts cycle life by 50% compared to traditional AGMs
  • 7 year market leading pro-rata warranty for true peace of mind


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

I bought two 280 ah deep cycle batteries in December 2019. Firstly, even though Christmas was close there was no delay in delivery, 4 business days was all it took for an interstate delivery! Secondly, I'm into the third month of our full time life in the road off grid, powering 2 fridges & 2 separate freezers, a 72 inch flat screen tv most nights, assorted lights & rechargers operating constantly, with occasionally, on a low setting, our portable air conditioner, hair straighteners & hair dryers.. 600 watts of solar each day run into a 30 amp MPPT Tracer then to our 2 batteries, to our 3300 inverter, all bought through Aussie Batteries & not once have we been found short of power! Not once. I asked for & was given all the advice I wanted & some I needed lol. I'm so happy & now with the quite serious situation regarding covid-19, we are isolating on a massive beach overlooking the Indian Ocean. We couldn't have done this without Aussie Batteries help I honestly believe. From the solar to MPPT to inverter to batteries, everything was & is a great product. Seriously Thankyou guys for the products, the advice & the security we now feel being reliant on your products. Andrew & Kerry Stewart.

Fantastic Product So Far

We installed 2 of these batteries (24v) on our houseboat hooked up to a solar array that has not seen a lot of sunlight the last few weeks. They have performed exceptionally, powering everything through a 5000w inverter. Amazing and thoroughly recommend.Also delivery was prompt as promised.

280AH 12V Eclipse AGM Deep Cycle Battery

On 23rd of December at 12:17 pm I placed an order for 2 batteries after a breakdown. I fully expected not to have batteries until about 7th or 8th of January. The team at Aussie Batteries processed the order and shipped by 16:38 on the 23rd, we had a phone call from TNT the next morning to confirm that someone was on site to accept the delivery. So we had the batteries and were able to install them on boxing day and keep the coffee van operating. The batteries themselves have some very nice little features such as built in volt meter, and auto top up. I am very pleased with the product and service.
