Battery production dates are usually marked on the battery, with different manufacturers using different labeling methods. Below are common battery production date coding methods: 1. Six-digit numbers: For example, 21115 indicates the battery was produced on November 15, 2021. 2. Combination of letters and numbers: Some production date labels require careful identification. For example, 20a2052039 represents January 20, 2020. 3. Some batteries have laser-engraved codes: For example, 2020117051A means the battery was produced on November 17, 2015.
