Deep Cycle Batteries: Types, Benefits and Buying Tips
Utes, boats, motorhomes and caravans all rely on deep-cycle batteries for power. They run everything from winches and off-roading lights to fridges and ovens, and store backup power from vehicle solar installations. Unlike starter batteries that provide short power bursts to get engines going, deep-cycle batteries are designed to give a consistent charge over a longer period. This makes them ideal for keeping the AC on in hot weather, pumping fresh water, lighting camp sites or binge watching your favourite shows.
A major benefit is that the batteries can be repeatedly discharged to much lower levels (often lower than 50 per cent) than their starter siblings, and recharged thousands of times without losing capacity or enduring physical damage. Several types exist, from simple lead-acid to lithium deep cycle batteries with higher discharge rates and longer lifespans.
