Every cell in this lot measured inside the 4700–4980 mAh band on our grader — this is the spread, not a headline number.
How to read this report
- Tested capacity range
- The band every cell in the lot measured within on our grader — an honest spread, not a single marketing figure.
- Internal resistance (IR)
- Lower is healthier. High IR runs hotter and delivers less usable power under load.
- Storage SOC
- The charge level the lot ships at — set for safe transit and shelf life, not full.
- Batch ID + QR
- Tied to this exact lot. Re-scanning the QR reproduces this page, so a report can't be faked or edited after the sale.
