Batteries vary quite dramatically and this is reflected in both life expectancy and performance.
Some batteries like the Discover ECL have element and anchor bonding technologies to assist in high vibration applications like cattle trucks up north or nut harvesting machines or shakers as they are often referred to.
Heat is another factor; some batteries have passive mixing technology which helps keep the batteries cool in the Mallee where temperatures can reach over 48 degrees Celsius.
Some batteries have a thicker plate that can handle the rigors of winching and light electrical loads often seen in four-wheel drive applications.
