Is there a limit to how many times these batteries can be recharged before they are no longer functional?

I'm wondering about the 2300 mAh AA batteries in the kit though. Made in Japan batteries implies rebadged Eneloops. But I'm not aware that there have ever been 2300 mAh Eneloop batteries being marketed. At first, I thought the Energizer AA batteries may be rebadged Eneloop Pro batteries. But Eneloop Pro AAs are rated at 2550 mAh as far as I know. Maybe they really are rebadged Eneloop Pro, but were binned out because they couldn't reach the 2550 mAh spec. Does anyone have personal experience with 2300 mAh Made in Japan Energizer batteries?
I know that is not a great comparison and some may argue that was batteries 5 years ago, things have changed, depends on how you used them, etc...but that is my limited observation. Any others want to weigh in?
Are those Energizers made in Japan or China? Energizer was using China for awhile -- I think around 5 years ago -- until they learned their lesson.
I am testing one of the Costco Energizers right now, just to see their capacity from new. My test indicates the AA's are 2450mAh capacity, AAA's are 900mAh. They were at ~55% capacity in package which indicates they were either not precharged, or possible manufactured a few years ago.

I think they are LSD, mostly because they appear to be coming from a Japanese manufacture that only produces LSD cells. Since it appears they were not shipped precharged, only time will tell. If they only drop to 2100mAh after a year of storage I suppose that would be confirmation.
