I wasn't really expecting these to be much different than the name brand batteries and it turns out they are really great! To do a thorough and scientific comparison I constructed a de-charging rig that consisted of a 5 ohm equivalent resistance and an analog to digital converter. I discharged the batteries at a rate of approximately 0.25 watts (the rate did vary some with discharge state). I collected 5 voltage readings across the test rig per second and averaged those down to 1 reading/second to reduce variability. I've attached the results as customer images, but the rundown is this:

Eneloop Batteries, 2000mAh (slightly used through <10 discharge cycles)
Battery 1 - Capacity 1928 mAh
Battery 2 - Capacity 1966 mAh

Amazon Batteries, 2000mAh (<3 discharge cycles, new)
Battery 1 - Capacity 2016 mAh
Battery 2 - Capacity 2006 mAh

Overall these batteries seem to be nearly identical in their discharge behavior and capacity to that of the name brand with about $0.25 price difference at the time of this review. I'll be buying these for sure and possibly updating after several hundred charge cycles.

AA NiMH Tenergy Centura AA Low Self-Discharge LSD NiMH Rechargeable Batteries, 1 Card 4xAA

purchased Tenergy Centura AA Low Self-Discharge (LSD) NiMH Rechargeable Batteries, 1 Card 4xAA. These batteries are doing great for my first month using them. 

I use them in my Sony portable CD player to listen to books and they are much better than the Energizer Rechargeable batteries that I had been using. Plus they have held their charge longer than the Energizers. 

I guess the LSD[Low Self Discharge]is responsible for this. I, also, purchased the [Tenergy Centura AAA Low Self-Discharge (LSD) NiMH Rechargeable Batteries, 6 Cards 24xAAAfor my MP3 Player and use 1 battery in it (again listening to books)and 3 in my books light. They are doing better than expected. 

The AAA is holding it's charge very well...changing the battery every 24-26 hours of play for the MP3 player and changed it out after 6 nights in the books light (which I am using as a portable night light while staying with my daughter and new baby). 

I could have gotten more time out of the book light, however, the light was starting to get a little dim and I chose to change it out rather than see exactly how long it would take to wear it down completely. I am EXTREMELY satisfied with these products, especially since I read such poor reviews on the regular Tenergy batteries. The Centura has exceeded my expectations and the price made it well worth it. 

With that being said, I have only had these batteries for a month or so and can't comment on the long term wear of them.

THE QUICK TAKE: The AmazonBasics High Capacity AA Rechargeable batteries are a nice product, but that comes at a higher price (at current pricing). Unless you need the extra capacity of a 2400 mAh battery, you may want to get the regular 2000 mAh Eneloop or AmazonBasics batteries at a lower price. Similarly, if you don't need to store them before using them, conventional rechargeables will do the job.

The product description on the Amazon product page has a good summary, if you're not familiar with the advantages of "pre-charged" or "low-self discharge" batteries. This is a somewhat new technology, available in the last 10 years or so; the batteries are slow to lose their charge, so they can be sold charged and ready to use; and will hold a charge for some time. It's only relatively recently that higher-capacity versions have been available.

If cost isn't important, and you don't want to have to figure out which battery is which - then sure, stock up on these. But given the cost, most people will want to use these where they are needed.
