A battery has a date code of "A-4"; when was the battery manufactured?

Date codes like this often use a two-part system: a letter for the month and a digit for the year. The letter A stands for January, and the digit 4 represents the year 2014 (within the 2010s decade). So the combination indicates the battery was manufactured in January 2014.
