BTW, mine says: 0 7 -07I0
does that mean these were made during July of 2007?
Correct according to post by many who have checked and verified the data. Do a search on Eneloop dates or such. Read a few thousand post.
Half life, what half life. I do not care to purchased half dead cells for new prices. When a cell only delivers 80% of its; new capacity it is considered used up.
Go to BatteryUniversity and many other such sites and read about rechrgable batteries. I have 45 years experience with Nicads,20 years experience with NiMH, over 5 years experience with LiPolys,3 with LiFePO4s. I am still learning but would like to think that all the years of reading,using ,testing have not been a complte waste of my time.

How to store batteries (BU20)
Batteries are perishable products that start deteriorating right from the moment they leave the factory. There are simple preventive measures that battery users can apply to slow the aging process. This paper provides guidelines to reduce age-related capacity losses and how to prime new and stored batteries.
I have never see a Dist. store all cells under ideal contions and neither do the magarity of retailers. Not cells are in non climat controlled locations for weeks,months and even years at a time.
I recently purchased (not Eneloops) 16 AA LSD cells which I have cycles over 20 times and they still need more cycling. My guess is they were on sell to clear out very old inventory.
Nice of a rep. from Thomas Dist to drop in but their comments did not address the 0808 Eneloop and then 0707Eneloops one month later situation.
I guess I could have returned the 0707 ones and requested fresher ones . To late now as I have already cycled them and most have magic marker ink on them.
Post 15 Eneloops received 0811 so does that mean that any sold now are atleast that current?
