Eliminate low-quality cells from the production line before they enter your batteries
Match identical-quality cells to consistently build stable, high-performing battery modules.
Limit risks of battery failures, product recalls, and warranty claims due to faulty cells.
Challenges in battery pack production in the industry
We understand that ensuring the quality of battery cells is critical to building high-quality and consistent batteries. Traditional testing methods often fall short, resulting in issues that affect the overall performance and reliability of your battery packs.
- Standard tests (OCV, AC-IR, DC-IR pulse, and capacity) have been proven to be inaccurate in detecting weak or mismatched cells.
- Low-quality cells can lead to uneven heating, performance degradation, and potential safety risks in your battery modules and packs.
- Inaccurate testing methods result in unexpected failures and increased warranty claims.

Frequently asked Questions
No. These methods are derived from the lead-acid battery industry and have already been proven to be uncorrelated and poor indicators of Li-ion cell quality and performance.
Pulse tests change the cell’s temperature and state-of-charge, leading to inaccurate measurement. RapidEIS provides a complete impedance profile with true DC-IR assessments without any altering the cell state in any way.
Capacity (both initial and middle-of-life) is the symptom, not the cause of aging. Impedance reveals the real issues and the cause of aging. RapidEIS correlates strongly with both current and future battery performance, and with future capacity.
