  • UN 38.3 – Transport safety testing for lithium batteries

  • UL 1642 – Quality and fire risk prevention

  • IEC 62133-2:2017 – Portable battery safety under real-world use

  • IEC 62619:2017 – Industrial battery safety and reliability

  • CE – European compliance for safety, health, and environmental protection

Manufacturing facilities are fully accredited to:

  • ISO 9001 – Quality management

  • ISO 14001 – Environmental management

True Capacity, Honest Ratings

We quote C5-rated capacity, not inflated nominal figures. This means our 100Ah battery will reliably deliver 20A of current for 5 hours straight — exactly what you expect from a true 100Ah 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.

When connecting multiple batteries in parallel, total discharge current scales with the number of batteries. For example, two batteries can safely deliver up to 200A combined.
