Start with the question
Understanding battery label dates starts with the original document, not a guessed conclusion. A battery label may contain multiple codes whose meanings depend on the manufacturer. A code is not by itself a diagnosis, a life expectancy estimate or proof of warranty coverage. The Motrelisk reading file focuses on date codes; warranty text; manufacturer references. Keep the document name, issuing organization, relevant version and the passage you are trying to understand together. A short note can help distinguish a statement in the source from an assumption added while reading. Do not upload personal records to this site; this is a public reading guide, not a review service.
