I just received 8 of these and ran a 500 ma discharge on them to check the capacity before giving them a charge. They were all between 521 and 529 mah in capacity (using my maha mh-c9000 charger). Average was 525.5 mah. Considering that they are rate at 750 mah capacity they held 70% of the total capacity. They were manufactured in “2014 10” so I assume October 2014.

These batteries are likely eneloops according to at least one review on Amazon. I got them through amazon.ca and they were the best deal on a good quality aaa rechargeable that I could find.

Amazon describes them as:
AmazonBasics AAA Ni-MH Pre-Charged Rechargeable Batteries (8-Pack) – 1000 Cycle (Typical 800mAh, Minimum 750mAh)

In the description they claim that they hold a 70% charge after 3 years.

I’m currently charging them and will run another 500 ma discharge test on them to check the fully charged capacity. It will be interesting to see if they perform similarly to the eneloops recently tested by HKJ in this thread:

John.

Based on your narration above, it looks that you performed a discharge test ‘out of the box’? If so, then that 70% capacity is spot-on as they are charged to about 70% when ready to be sold at the shelves.

I would be amazed if they are eneloops – Amazon reviewers aren’t exactly the most reliable. Amazon.uk sell a pack of eight of these for £10.99, which isn’t that different from the 4th gen. eneloop price.

What other AA/AAA NiMH batteries are made in Japan and charged with renewable energy?

Don’t know. Fujitsu, maybe? I’ll wait until HKJ runs the Amazon batteries through his tests before I get too excited. As I said, the price of the Amazon ones isn’t exactly bargain basement – even when they are available as lightning deals (which is often).

Guess what? They’re the same battery. It’s not too hard to put 2 and 2 together.
