330AH Deep Cycle AGM Battery - Giant Power 330AH AGM Battery with Australia Wide Delivery & Fast Shipping

For those who demand maximum power and unfailing performance, this 330AH Deep Cycle Battery is perfect! This 330AH battery will give you a huge possible power output, low self-discharge capacity and maintenance free construction. Deep cycle AGM Batteries are perfect for applications that require either frequent cycling or renewable power storage. Common uses include running appliances when camping away from power, using with a solar panel for charging, running in a dual battery system in a vehicle, or providing safe power on a boat. This battery is ideal for the consumer looking to set up a large scale power supply or is the perfect solution for large portable power storage.

When you need a long lasting battery that can withstand the tough Australian conditions, deep cycle AGM batteries are a great choice. AGM Batteries use glass mat technology within the battery to absorb the acid, as opposed to standard flooded batteries where the acid is free flowing. This provides several key advantages over standard batteries, such as allowing the batteries to be 100% sealed, non-gassing and maintenance free (batteries will never leak acid, even if damaged), and providing a significantly longer service and cyclic life (up to 2-3x longer than standard batteries). AGM batteries can last twice as long as a standard lead acid battery, making them more reliable and durable. This high capacity powerful battery provides a great response to load, and can handle constant discharge or occasional use with very little need to recharge. Ideal for a range of activities, including fishing trips, providing power whilst camping, providing power in a caravan or motorhome, or even for supporting a solar or wind energy system, the uses are endless! 

330AH 12V AGM Deep Cycle Battery Features:

  • Sealed Construction
  • Maintenance free operation
  • Non-Spillable, Non-Gassing
  • Designed Service Life 12 years
  • Ideal for frequent cyclic discharge
  • Exceptional deep discharge recovery performance

Excellent service

Purchased 5 300 amp hour batteries approx. 6 months ago. 4 for 48 v stand alone and one for 12v set up. In due course one of the 4 died. Being a realist, these things happen. A phone call to aussie batteries and a check by local auto electrician and faulty batttery confirmed. Aussie replaced dead battery without quibbles. During exchange I raised concerns that the other batteries may be compromised, and told to keep an eye on them. I understand that one dead battery in a series bank can affect the others in that bank. Replaced dead battery with the 5th one as they were matching and kept replacement for 12v system. In time the other batteries showed signs of faiilure. Phone Aussie and asked to bring them in for testing. 3 failed one passed. I had during this time found a couple of reviews about AB that raised some concern. Anyway, spoke to AB about batteries and they replaced them without any hassle. I have found dealing with AB to be pleasant and easy. I have no hesitation in recommending them and hope to purchase from them when I build my house and upgrade my system to suit. Thank you Aussie Batteries.

Aussie Batteries - 330AH 12V Giant Battery 1st Try

Well the battery was dispatched on time with my only bitch being our good old transport Co who’d lost it locally in their yard. Waited 5 days before fronting Toll for answers.. finally got it delivered with help from retail side of Toll.. The Battery so far looks to be doing the job covering our aquaponics setup regardless of the weather conditions, discharge overnight sorted when the suns up. Stunning experience actually after my last 220AH x 2 6V deep cycle batteries.. 7 years old too.. Looking forward to seeing how this unit lasts with all our panels now locked and loaded.. 33Amp input today.. nice. PL40 Plasmatronics controller manages it all.. Big plus so far.. thanks to Aussie Batteries once again.. service and help sincerely appreciated
