A battery can pass every voltage check in the lab and still fail a customer on a cold winter morning.
That's the gap High Rate Discharge (HRD) testing is built to close.
Unlike a standard capacity test (which measures total energy stored over hours), an HRD test asks a very different question: can this battery deliver a massive burst of current, instantly, without its voltage collapsing? For automotive and industrial lead-acid batteries, that's the real moment of truth.
We just published a deep-dive on what HRD testing actually checks and the 6 specs that separate a production-ready HRD tester from a lab instrument that can't keep up with your line:
- Test time per battery
- Discharge current range (500A to 3,000A)
- Data logging and traceability
- Line integration (standalone up to 5-in-1)
- OCV pre-check and automatic pass/fail logic
- Build quality for years of continuous production
Our HRD units process up to 8 batteries per minute. If a battery fails under real load, it gets automatically rejected before it ever leaves the plant.
