End-to-End Control
Quality Control Flow
Every battery passes through six mandatory quality gates -- from raw material receipt to final shipment -- ensuring consistent performance and full traceability.
-
STEP 01
IQC
Incoming Quality Control -- raw materials, lead alloys, separators, and electrolyte inspected against spec before production entry.
-
STEP 02
Process Control
Critical process parameters monitored at grid casting, plate curing, assembly, and electrolyte filling stages.
-
STEP 03
Formation & Grading
Charge/discharge formation cycles with automated capacity grading and internal resistance measurement for consistency verification.
-
STEP 04
Performance Testing
CCA, capacity, reserve capacity, and voltage tested per DIN/JIS/BCI standards. Samples selected from every production batch.
-
STEP 05
OQC
Outgoing Quality Control -- appearance, labeling, terminal torque, electrolyte level, and packaging integrity verified before release.
-
STEP 06
Batch Traceability
Date code, batch number, and production records retained for full traceability -- supporting OEM audit and post-market issue resolution.
Laboratory & Field Validation
