5No, those are NOT rebranded first-gen Sanyo eneloop cells
By NLee the Engineer
I have previously tested the original AmazonBasics NiMH Precharged Rechargeable Batteries (in black wrappers) back in 2011. Recently I purchased a set of those new AmazonBasics NiMH Pre-Charged Rechargeable Batteries (in white wrappers), because people kept asking me: "Are those rebranded 1st-gen Sanyo eneloop batteries?" Based on my observations so far, the short answer is "NO". But wait, don't leave yet!

I measured the capacities of those AmazonBasics AAA batteries, using my La Crosse BC1000 charger. Here are my findings:
- Right out of the package, the average remaining charge is 562mAh, or 70% of the rated '800mAh' capacity.
- After one recharge/discharge cycle, the average capacity jumped to 797mAh.
- After another 2-3 more cycles, the average capacity leveled off at 821mAh

The above behavior is consistent with my previous test results for original (1000-cycle) eneloop, 2nd-gen (1500-cycle) eneloop and 3rd-gen (1800-cycle) eneloop cells. Note that just as in this case with AmazonBasics cells, all eneloop cells are charged to around 70% when they left factory.

Based on electrical characteristics, I believe that those white AmazonBasics cells are indeed rebranded Sanyo eneloop cells. But it is impossible to tell whether they are in fact 1st- or 2nd-generation eneloop. This is because to the end-user, there are no measureable performance differences between 1st, 2nd or even 3rd-generation eneloop cells beside their cycle life claims.

Because of the '1000-cycle' claim, most people would jump to the conclusion that white AmazonBasics cells are equivalent to 1st-gen Sanyo eneloop. My closer examination, however, suggested that they are more likely to be rebranded SECOND-generation eneloop instead.

Please refer to the picture I uploaded to 'Customer Images' section. Look closely at the positive terminals of those three types of batteries, and you'll notice the difference in their so-called 'vent holes' (the name is misleading because those openings are not actually used for venting):

In the case of AAA cells:
- First-gen eneloop AAA cell has triangular-shaped vent holes
- Second-gen eneloop AAA has vent holes with rounded tops
- White AmazonBasics AAA has vent holes with rounded tops

In the case of AA cells:
- First-gen eneloop AA cell has triangular-shaped vent holes
- Second-gen eneloop AA has no vent holes
- White AmazonBasics AA has no vent holes

Therefore based on their mechanical aspects, I have to say those white AmazonBasics cells are most likely rebranded 2nd-gen Sanyo eneloop cells.

Why would Amazon intentionally sell rebranded 1500-cycle eneloop cells as just 1000-cycle? The answer is Price Differentiation. Manufacturers often de-spec a product when it is sold under different brand at a lower price. Otherwise it will erode the market for their higher-priced brand.

What if I'm wrong and those AmazonBasics cells are 'only' 1000 cycles? Well, you could find out the difference in... TEN years. So for now, just pick whichever brand is on sale and be happy.

5The real world experts have weighed in and they say its a 4-way tie!
By Dee Fields
I've been reading so many reviews on Amazon for too long and realized that I sill didn't know what AAA rechargeable NiMH batteries to buy (3 out of 4 of the ones I'm looking at have well over 2,000 reviews with a greater than or equal to a 4.4 rating! No wonder all those reviews still left me scratching my head because so many reviews across all the batteries with such a rating are just that well written!) I finally came to my senses and found a great article on the Internet that actually represents my and possibly your dilemma over picking the right rechargeable battery. It's so short and sweet. The answer is between all 4 brands (i.e., AmazonBasics, Energizer, Eneloop, and Duracell), there is practically no significant statistical difference and because of that fact, they recommend that we just buy whatever is the cheapest at the time we are buying. (The study is from 2017 and they did rigorous testing on the batteries)

Amazon policy disallows links to sites outside of Amazon. The best I can do to direct you to said article is this: Do a google search for the following exactly as I have typed it, including quotes:

"The Best Rechargeable AA and AAA Batteries" site:thewirecutter.com

As of the time I am writing this review, the article is the first search result from Google. If you are using other search engines, you will likely have to leave off the: site:thewirecutter.com
Just use the title of the article and make sure you land on thewirecutter.com web site.

I am against any compensation via discounts, coupons, or any other cost break for giving reviews. This review is my true experience.

4good so far.
By Maleko
i bought these and the amazon basic black AAA batteries. I haven't had time to test the longevity of these as i just got them yesterday, but after reading other posts and questions, these (white) are not better then the black batteries. They both are made in japan, black and white, and the whites are 750-800mah rated, the blacks 850mah rated. I read the whites were eneloops, and the blacks made in china, but it seems the blacks are slightly better performing, and thus the few dollars more for the blacks. Will report more after i use them, but so far all the batteries are charging fine and seem strong.
