How To Read Car Battery Date Codes - Battery Globe 

Yes

The "3" stands for the last digit in the year, so 3 can be, 2003, 2013, 2023 or even 2033. The same applies with other numbers, Let's say "7", that means 2007, 2017, or 2027. But what if you want the specific year of the battery? then you pick the closest to the current year, because no battery lasts for more than a decade. So lets says "D1" is shown in a battery, it would April 2021. Hope that helps

Brother Nicholastoo858, your post was FUNNIER than hell! I laughed so hard that I accidentally choked + snorted some of my iced-tea out my nose! Your comment is also VERY correct indeed!

@@martinbachmann6283 😂😂 Was a pleasure doing business with you sir!

Yes they do

@@learnsomething6265 I have found no expiration date on any model of car battery.

@@akbarshoed It's supposed to be written in code form or it could be on a sticker. Not sure which brand u have?

@LearnSomething all I see is manufactory date. No expiration date

@@akbarshoed Oh excuse me, there is no expiration date. the manufacture date is what you need. I try not to buy batteries that have been sitting on the shelf for too long so I always check the manufacture date.
