Test / Review: Contour AA (Green-cyan)

Batteries and Chargers Rechargeable Batteries

Contour AA (Green-cyan)


Official specifications:

  • None





Maximum temperature raise at different discharge currents: 1A:+1,4°C, 2A:+3,7°C, 3A:+5,9°C, 5A:+11,1°C, 7A:+16,2°C, 10A:+21,9°C,












The performance between the two tested cells is fairly consistent. There is a minor capacity difference, but the voltage during discharge tracks very well.















Conclusion

I got these batteries without any description or specifications.
The test shows that their performace is good.
Note: The test does not show how well they will age.



Notes and links

The batteries was supplied by Don from BLF for review.

How is the test done and how to read the charts

It seems to me that these don't hold their voltage too well after 4-5A. I'll be interested to see these alongside Eneloops.

Thus far their self-discharge is comparable to Eneloops.

Hi HKJ,

How do you think these compare to 2nd gen eneloops? I started all this about a month or two ago when they were on offer at Amazon. When I received them I realised that they seemed, physically, identical to the eneloops. So I put up a deal alert.

What do you think?

Haha, You beat me to it Don. Must type quicker. :bigsmile:

Thanks for this HKJ. I bought some of these on the strength of Marcl’s recommendation here. and your test seems to confirm that they are good cells. I’ve subsequently bought a Contour charger and 4xAA’s pack from iCell media - the same Amazon retailer where these came from. Good value at £8.19, even though I bought it to give away!

Edit>> knew i should have concentrated on my post, rather than watch the snooker!

Their performance is not exactly the same as eneloop.

Comparing at 1Ah the eneloop has slightly higher voltage at lower currents.

The capacity of Eneloop is lower at low current and higher at high current.

I have to say they look very close indeed.

Thanks for the review, HKJ! Do you have any 2nd generation eneloop tests to compare? HR-3UTGB are 3rd gen.

9

Ah yes, well spotted! :wink:

Marc.

It does not look like I have any second gen. I bought a lot of first gen and have not needed to supplement.

11

Ahh. Thanks, HKJ. I only have some 2nd gen AAA. All my AAs are 3rd gen, but I am thinking of getting some eneloop lites too.

Thanks for the review.
So I guess they were a good deal for the price.

Thanks a lot for the review! Frontpage’d and Sticky’d.
