From left to right the numbers on the top of the battery read:

1K05BN1F 01788502 1K19Z60

I thought that the pertinent code was the one on the far right, and I'm guessing the K means November. Is it 2011 because of the 1K or is it 2019 because of the 1K19. I'm just not sure. I thought that it would be letter first and then number, but I don't see it stamped in that format on the battery.

Am I looking in the wrong place, or are these the right numbers to tell the battery manufacture date?

It's a 2012 Ram 1500, and I'm wondering if it's the original battery since it's stamped Chrysler. Or maybe the previous owner bought a dealership replacement at some point.

They usually have a round sticker on the end/side of them that tells you mo/yr. Remove it and look.

I could not find a sticker, but when I removed the battery I found this on the back. It looks like X N6 X. Since N doesn't correspond to a month, I'm still not sure. Perhaps the 6 means 2016? The truck didn't want to even crank when it was down to 5 degrees last week, but it started fine today when it was 35 degrees.

I think my issue may be somewhere other than the battery, but since it looked old and was testing on the low end of acceptable, I went ahead and replaced it anyway. We'll see if it starts the next time the temperature drops low.

Do you by chance have any numbers stamped into the case next to the negative post? They may be under the wire. The Mopar batteries I have seen show the year, a letter for the month, then followed by the day of the month there.
