If you don't know the year of manufacturer for your AGM's, here's how to determine the age:

Just below the post/blade on the casing is a series of letters stamped into the plastic such as BJJDA or BJJDC. Ignore the BJJ or whatever you have on yours and use the last two letters for year and month.

Example - BJJDA - The D is year 2004, the A is January
BJJDC - The D is year 2004, the C is March

Hope you have at least a "B" or it's battery time.:(
