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

330AH AGM Deep Cycle Battery

Great service . Awsome Battery . Runs 210 litre NovaKool fridge freezer and 80 litre Engle freezer on our boat with all lights TV etc . No problems at all lucky to drop 25% overnight recharge via 500 watts roof mounted solar panels , Was a replacement for 4 x 110 AH AGM Batteries . The new 330 AH AGM is far superior .
