Hard Korr’s lithium deep-cycle batteries offer a direct drop-in replacement for existing sealed lead acid (SLA) batteries.
With a tough, cushioned metal frame, top-quality LiFePO4 cells and the ability to be connected in series to create up to a 48V setup, it is suited to a wide range of applications including 4wd, camping, marine, RV and electric vehicles.
The Hard Korr® Difference
Don’t be fooled – batteries might look similar on the outside, but the key differences between low-quality and high-quality batteries are on the inside.
Our battery cells are protected by a strong, custom-designed metal frame with inbuilt shock absorption.
The frame offers protection against knocks and drops, and ensures better stability and longevity when used in high-shock and high-vibration environments such as marine and vehicle applications.
