How to Check the Date on a Car Battery?
1 Answers
To check the production date of a car battery, generally follow these steps: 1. Some batteries have the production date marked with numbers. For example, "121017" indicates the battery was produced on October 12, 2017. 2. When checking the production date, carefully inspect the battery for markings. 3. The first digit represents the year of production, "4" means 2014, "h" stands for August (counting from "a," where "a" is January), and "31" represents the 31st day. 4. Some batteries have laser-etched production dates, such as "20171123041A," indicating the battery was produced on November 23, 2017.
