LiFePO4 Battery QR Code Decoder: Verify Cell Authenticity, Date & Capacity Instantly

Tools & Guides by Gobel Power Team | LiFePO4 Verification Standard

Why Verify QR Codes? Every brand-new Grade A LiFePO4 cell (EVE, CATL, Lishen, REPT, etc.) features a laser-etched metal Data Matrix QR code. Using the Gobel Power Battery QR Decoder, solar DIYers and energy storage integrators can parse 24-digit or 19-digit codes based on national battery coding standards to instantly uncover manufacturing date, factory location, cell type, nominal capacity, and avoid re-printed or recycled cells.

1. What Information Can You Decode from Your LiFePO4 Cells?

  • Manufacturer & Factory Location: Identify official manufacturers including EVE Power, CATL, Lishen, REPT, and CALB.

  • Exact Production Date: Read the precise year, month, and day of cell production to check cell freshness.

  • Product & Battery Type: Verify whether it is a Battery Cell (4th character "C"), Battery Pack ("P"), or Module ("M").

  • Capacity & Voltage Specs: Inspect original factory rated capacity, test data (OCV, internal resistance), and voltage parameters.

2. How to Read a 24-Digit Standard Battery QR Code

Code PositionDecoded DefinitionExample Analysis
Digits 1–3Manufacturer Vendor Code04Q (EVE Energy) / 001 (CATL)
Digit 4Product CategoryMust be C (Cell), P (Pack), or M (Module)
Digits 5–7Battery Chemistry & SpecificationB = LiFePO4 (LFP) Battery
Digits 8–10Production Date CodeDecodes Year, Month, and Day

⚠️ Beware of Fraudulent & Re-printed QR Codes

Some unscrupulous suppliers scrape off original QR codes and re-laser fake codes over polished surfaces to mask Grade B or used cells. Always compare the decoded date and capacity with physical cell dimensions, weight, and internal resistance (Ri) test readings.
