True Capacity, Honest Ratings
We quote C5-rated capacity, not inflated nominal figures. This means our 150Ah battery will reliably deliver 30A of current for 5 hours straight — exactly what you expect from a true 150Ah battery. Many cheaper alternatives exaggerate their specs by using nominal ratings, which can be up to 20% higher than real-world performance. With Hardkorr, you get authentic capacity, honest data, and dependable power.
Important Note
This battery is not designed for under-bonnet installation OR cranking purposes.
When connecting multiple batteries in parallel, total discharge current scales with the number of batteries. For example, two batteries can safely deliver up to 400A combined.
