The images and description no longer match what they actually send you. Last year they were made in Japan and matched the photos but now they are made in China with slightly different packaging (and I assume much lower quality). When I received the Chinese batteries I contacted customer service to get the proper batteries and they sent me another batch of Chinese ones. For a company that doesn’t pay any taxes they sure like to pinch those pennies.

Many customers who have been buying these for a few years have found the Amazon Basics batteries have a noticeable quality difference between those made in China and Japan. I.e. the Japanese ones are better. When I made my purchase, the product description said ‘Made in Japan’ and that is why I chose to buy this one and not from other listings. The product I received was the Chinese batteries. Now I review the listing and find that the product description has been deleted – and the honest truth has NOT been entered in its place. This seller is deceptive.

While expensive initially (~$16 for 8 batteries, or $2 a battery), these have the potential to save you a lot of money. A lot. Spending $100 on rechargeable batteries (AA and AAA) and docks should give you plenty of batteries to last you for years. When you recharge these, it will cost you pennies.
Cost wise, these are very effective if you’re going through a lot of batteries. The charge times are kind of long, ranging from 6-8 hours for the AAA and 8-12 for the AA. They are very slow to charge, so make sure you have a few spares if you need them immediately. The AAA batteries are 800mAh, and should cost less than a penny to recharge from empty to fully. It should take less than 100 watts (0.8A, 120V, pf 1.0) to recharge a battery. One kilowatt (1000 watts) in Alberta is around $0.06/kilowatt hour.
So after just a few recharges you’ll save quite a bit of money. If your batteries stay on the dock for more than a few weeks at a time, cycle them out so you don’t ruin the batteries. Nickel–metal hydride battery suffer from what some people call “memory effect”. Make sure to full charge then fully discharge these batteries to maintain the best battery health.

Not quite sure what High capacity is meant to mean. Bought a combination of AA and AAA. 3/4 of batteries fall short slightly of advetised capacity of min. 800mAh for the AAA and min. 2500mAh for the AA. The worst being 4 of the AA’s only having a charged capacity of around 800mAh compared to an advertised minimum of 2000mAh.

Please watch out guys. In this product description it clearly states those batteries are made in japan. However, the ones i receieved are made in China. I m returning them immediately. Please watch out if you received correct ones.

I purchased 8 AmazonBasics AAA High-Capacity Rechargeable Batteries (Silver Label from Japan) Capacity:850mAh Minimum:800mAh.
At first, I was disappointed by the performance of these batteries. Let me explain why.
I used my Tenergy 456 battery charger to test cycle the batteries. This charges the batteries then drain it to determine the capacity of the battery. I set the charger to charge them at 300ma (lowest setting) and drain them at 250ma. The results were quite disheartening.
With a charge rate of 300ma, testing the 8 batteries gave me the following results:
Test#1: Lowest: 686 mAh Highest: 746 mAh Average: 719 mAh
Test#2: Lowest: 755 mAh Highest: 811 mAh Average: 776 mAh
Test#3: Lowest: 757 mAh Highest: 800 mAh Average: 774 mAh
Test#4: Lowest:754 mAh Highest: 798 mAh Average: 769 mAh
Something was evidently wrong. I got nowhere near the 850 mAh expected capacity.
I was asking myself why pay more for a “high-capacity” battery when the AmazonBasics AAA (white label from China) consistently tests out at 800 mAh, performs better and costs less?
It then occurred to me to increase the charge rate from 300ma to 500ma. Here are the results:
With a charge rate of 500ma, testing the 8 batteries gave me the following results:
Test#5: Lowest: 810 mAh Highest: 891 mAh Average: 844 mAh
Test#6: Lowest: 858 mAh Highest: 932 mAh Average: 884 mAh
Increasing the charge rate dramatically improved the performance of these batteries by a significant 15%.
I then decided to see what would happen if I dropped the charging rate back to 300ma. Would the capacity fall back to 769 mAh? Or stay near 884 mAh?
With a charge rate of 300ma:
Test#7: Lowest: 844 mAh Highest: 930 mAh Average: 875 mAh
Test#8: Lowest:809 mAh Highest: 859 mAh Average: 826 mAh
Dropping the charging rate to 300ma shows the battery capacity slowly dropped back down.
Conclusion: To get the expected capacity of 850 mAh these batteries need to be charged at 500ma.
In test #6 this gives 10% better capacity than my 2nd favourite battery, the AmazonBasics white label from China which tests out at 800mAh.

These are good batteries for general purpose use, with a reasonable lifetime for low-medium drain devices. . Their only weakness is that dimensionally they are a fraction of a millimetre shorter and a fraction of a millimetre fatter than standard chemical cells. Both these things mean there are occasional problems in their use.
The length issue means that they do not always make good contact with the electrodes in some devices, requiring the electrode(s)to be ‘bent’ towards the battery in order to make sound electrical contact.
The slight increase in thickness can stop them fitting snugly in a battery compartment (possibly also hindering proper electrical contact as above), thus preventing the battery cover fitting well (or at all). This problem is rather dependent upon the exact design of the battery compartment but I have had to take a craft knife or small side cutters to compartments in order to allow the batteries to seat well.
However, most annoying is that the said dimensional variations can stop the batteries seating properly in the Amazon Basics battery charger. This only becomes apparent after charging a set of 4 batteries and finding that not all have actually been charged after the charging light has changed to green. The only way to sort it out is to put in one battery at a time to see if it starts charging. If it doesn’t, it can be very fiddly to get it to contact properly with the charging electrodes, since the battery does not seat right down into the holder and the charger electrodes have no real possibility of adjustment.
If these things were sorted, i’d give 5 stars.

約４年弱使用しての感想。充電はエネループ用充電器、使用用途はフラッシュライトと自転車のテールランプです。ライト用としては過不足なく使えます。ただ３年を過ぎたあたりから充電器より充電不可と判別される個体が出始めて半分が使えなくなりました。スペック上の充電回数の半分も使えなかったのは残念。SANYO時代のエネループはまだ使えているので長く使うなら高くてもそちらがお勧めです。

Low rating because I received the batteries promptly but was surprised to see them made in China vs. the description as made in Japan. It is the same 850mAh high capacity just look like Amazon has shifted manufacturing to China… Contacting support, let’s see what they say.

If you charge these batteries and then use them immediately, they are wonderful. On Bose noise canceling headphones they have lasted me nearly as much as alkaline batteries last (10-12 hours).
If you charge them, keep them charged for seven days before using them, there won’t be much energy left. On the same headphones they last just about one hour if they have remained unused for a week after full recharging.
Perfectly usable, probably deserving of 2 stars, if it were not for the entirely misleading “Maintains 65% of original charge after being stored for 3 years.”

El año pasado estas baterías estaban fabricadas en Japón, que es de donde proceden las mejores, pero desde el verano de 2019, el mismo producto ha pasado a ser fabricado en China. La descripción del producto dice “fabricadas en Japón” pero no es correcta.

Ipotizzando e leggendo in giro pensavo di acquistare le “alta capacità” made in Japan, invece non è così, o almeno, lo era. Ora le “verdi” sono made in China.
Ho avuto modo di utilizzarle in treni Lego pensando che l’elettrolita fosse non liquido, e invece lo è.
Giustamente il motore sfrutta “a pieno” la batteria NIMH, a fine corsa ho aperto il vano batterie e ho trovato un liquido oleoso trasparente, col rischio che questo rovinasse miei i treni.
Andranno bene per telecomandi e piccoli elettrodomestici, ma sicuramente non per radiocomandi, motori e altri apparecchi delicati.
PS: il prezzo di vendita è da “made in Japan” e non è specificato il paese di produzione nell’inserzione web, delusione.
