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).
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.
