Official specifications:
  • Typical capacity: 2500mAh
  • Minimum capacity: 2400 mAh
  • Nominal voltage: 1.2V
  • Life: 500 cycles
  • Low self discharge (LSD), 75% capacity after one year, 65% after 3 years

Maximum temperature raise at different discharge currents: 1A:+1,0°C, 2A:+2,8°C, 3A:+5,2°C, 5A:+10,4°C, 7A:+16,3°C, 10A:+23,1°C
This is the high capacity NiMH cells from Amazon (The black cells does also exist in a lower capacity version).

Very good discharge curves with perfect tracking between the two cells.

When we'll see AmazonBasics 18650s, for also half of price of Panasonics, that would be the best day :)

Today on Amazon , a 4-pack of Eneloop Pro AA sells for $16.79, and the equivalent Basics AA sells for 12.99.

Step up a level in quantity: For an eight pack, Amazon wants $20, while Panasonic wants $38. That's a significant difference in my book.

I always like to spend a little more for Eneloops, but in this example we're beyond a little more. Looks like a good deal.

Wait a minute... $38 is more than twice $16.79. The actual price on Amazon is $37.68, which is still more than twice the price for the 4-pack. So you're better off ordering two 4-packs for $33.58 in total. However, the 8-pack of AmazonBasics is $19.99, less than 60% of the Eneloops. In this case, looking at the curves, contrary to the white ones, I can't see anything wrong with these. They seem to reach almost the same capacity as the Eneloops, they only go down in voltage much faster at the end, which costs about 100 mAh in comparison. But they seem to have even a bit less internal resistance, holding up their voltage better at higher currents. Maybe their specs have been moved a bit towards regular Eneloops at FDK.

However, I'm seeing an even better offer... Amazon also has Duracell rechargeable batteries at $8,99 for a 4-pack. The downside is that you have to have at least a $25 order to be eligible to order a 4-pack of them (but you can order 3 4-packs which would work). These would be very interesting because they are also made in Japan and guarantee (!) 5 years or 400 cycles of life, whatever comes first. In fact they would also be interesting to test because, being Duracell, they are much more common than Amazon or Eneloop batteries. At least here in Austria, you can get them at virtually every local supermarket (at least BILLA, which is one of the biggest chains here). At first glance, they might be identical or very close to Eneloop XX/Pro's as well, even though their cycle rating is a bit different. Thus they would be very interesting for a test, for they may well be an even better offer than the cells tested here, at least if you want high capacity LSD cells.

Good catch on the (2) 4-packs @ $33.58. Still a decent savings though.

Just to clarify:
Basics 4pk
12.99
Basics 8pk
19.99
Eneloop 4pk
16.79
33.58 (two 4-packs)
Eneloop 8pk
37.98

I assumed it's from panasonic, as the discharge curves between this cell and the Eneloop are very similar.

Thanks for the reply.

Been using the Amazon Black AA cells in a NiteCore EA41 for about 3 months now. Performance has been as good as any Eneloop I've owned.

Nice review as always, and thank you! These batteries sound like quite the deal.

I got a set of 8 and it took 5 to 6 hours to fully charge in the bc700 at the standard setting. I think the cutoff is 1.47 volts. Next day I measured all of them and they all were 1.39 volts. Is that normal ? Date on them is December 2014.
So I am now doing a discharge refresh cycle which will likely take a couple of days. Hopefully the voltage will be steady.

Yes that's normal. You can't read nimh cells by voltage quite like you can with li-ion.

Thanks for the test HKJ. Do they slightly outshine the chinese made eneloop pros?
