Product identification and traceability help protect both SUNHE ENERGY and its customers, and we keep strengthening marking and QR-code tracking on our packs.

Why Traceability Matters

When a question arises in the field, fast traceability tells us exactly which lot, materials and process records are involved. This shortens investigation, supports corrective action and builds confidence that a product can be traced back through our production history. For custom programs where each build may differ, knowing which lot was used also supports accurate replacement and warranty handling.

Marking and QR-Code Tracking

We apply durable labels with lot and batch information, supported by QR-code records that link back to internal production and quality data. These identifiers stay with the pack from manufacture through delivery. The marking is designed to remain legible through normal use, so that even aged product can still be identified and traced.

Protecting Customers and Brand

Clear, verifiable marking also helps customers distinguish genuine product and guard against counterfeiting. As we scale custom programs, these systems become a routine part of how we deliver consistent, accountable battery solutions. They also make warranty handling and field support smoother for everyone involved.
