| Aspect | A-Grade Cell | B-Grade Cell |
|---|---|---|
| Definition | Fully meets all specs. Zero defects | Fails to meet one or more standard parameters but remains functional. Typically has minor flaws. |
| Cycle Life | Long. Retains high capacity after cycles. | Shorter. Capacity fades faster than A-grade. |
| Safety & Stability | High. Stable performance under various conditions with complete protection. | Acceptable. Slightly higher risk than A-grade under extreme conditions. |
| Price | High | 50%–90% of A-grade price, or even low |
| Method | What to Check | Reliability |
|---|---|---|
| Check QR Code | Mostly A-grade cells with clear and traceable codes, while B-grade cells with B (like EVE) or QR code covered. | Medium |
| Inspect appearance | Scratches, dents, rust, or welding residue → B-grade or salvaged cells. | Medium |
| Test the data | Check IR, Capacity value, and Batch Consistency. If values don't match the datasheet → B-grade. | High |
| Compare the price | Price 50%~70% lower than normal → highly likely not A-grade. | Medium |
| Request documents | Can provide original batch reports and grading data → A-grade. Cannot provide → be cautious. |
Medium-High |
