Hard Korr 100Ah Lithium (LiFePO4) Deep Cycle Battery

Our latest 100Ah lithium (LiFePO4) deep-cycle batteries are the most reliable, long-lasting batteries we have ever manufactured. With outstanding performance characteristics and full international certification, you'll never be caught short of 12v power on your 4wding and camping adventures again! Coming in a standard Group 27 (N70) size case, they are will fit into standard-sized battery boxes and trays.

These batteries are made using best-in-class robotic manufacturing processes with rigorous quality assurance (including serialised tracking) and pre-shipment cycle testing. We even store the test report for each battery for later reference if needed. That's why we can now confidently offer you a 5-year Australian warranty.

More usable power, longer life

When comparing batteries it is vitally important to understand the difference between nominal and C20 capacity. To reduce confusion and help to standardise the measurement of battery capacity, most reputable battery manufacturers will quote the capacity of their battery in amp-hours at C20 (also written as C/20), which means the number of amps the battery can deliver if discharged at a constant rate over a period of 20 hours. Using this standard, a fully-charged battery with a capacity of 100Ah could deliver 5A of current per hour for a period of 20 hours before becoming fully discharged (5A x 20h).

Some disreputable manufacturers, however, will advertise the nominal capacity of their batteries and bury the C20 rating in the fine print. Nominal capacity has no practical application and can be up to 20% higher than the C20 rating, so a battery that is advertised as a 100Ah battery might only be able to deliver 80Ah or even less.

We value our good reputation, and will always quote the C20 rating (or even higher) as the battery's capacity. This means you can be confident that the power we say our batteries can deliver is not inflated to mislead, create confusion or invite unfair comparisons.
