Hey folks, I just registered here and this is my first post... I've been reading up on NiMH cells, chargers, etc. and I have a question I haven't found an answer to.
I have a bunch of Powerex 2700 mAh AA cells, and I'm trying to figure out the date codes on them. So far, out of the batteries I've checked, I've found 3 different codes on the label near the seam: 15-03 U3, 15-11 UH, and 15-11 UI.
I found this thread from 2009, but the OP of that thread never got a clear answer. From what Maha told him, the date code isn't printed on the label, but instead on the "PVC tube" (the sleeve)? He cut off one of the sleeves and found no date code. Thread here: http://www.candlepowerforums.com/vb/showthread.php?237541
His date codes started with 07, and mine start with 15, which lead me to believe this is a year of manufacture. Most of these batteries were bought on Amazon in December 2015, but I did buy another couple 8-packs in October 2017. I haven't found any cells with a code starting with anything other than 15, yet. I have some in devices that I haven't looked at yet.
So... does anyone know how to read these date codes? Contrary to what was said in the thread from 2009, I believe these are date codes. I just wonder what they mean (besides the year).
I just got a Maha Powerex MH-C9000 (another reason I found this site), and I've been doing Refresh/Analyze on my cells, labeling them with their actual capacity so I can match them better in devices. For now I plan on grouping them by the codes I did find, so that batteries of the same age will be kept together.
Thanks...
