AA's are NOT 2600 mAh.....AAA's not 1000mAh
Fortunately, I have a La Crosse Technology BC-9009 AlphaPower Battery Charger so I am able to see the juice value in these batteries. When I first charged the AA's (slowly), I only got readings of between 900 to 1100 mAh. So I then refreshed the batteries (which can take days!!!) and got a maximum reading between 1821 -2360 mAh with an average reading of 2040 mAh for the 8 AA's so no where near their rated 2600 mAh. My new Sony and LaCrosse rechargeables charge to about 2600 mAh so I know the BC-9009 works okay.

Therefore, if you notice that the batteries aren't lasting after a charge you may want to refresh your batteries (that is discharge/recharge them a couple of times) to booast the mAh.

For the AAA's, after refreshing them I got a range of between 809 to 1101 mAh with an average reading of 911 mAh for the 8 AAA's.

So in summary (at least for the batch I got):

AA's are on average 2000 mAh (not 2600 mAh) which is about 80% of value.
AAA's are on average 900 mAh (not 1000 mAh) which is about 90% of value.

While the AAA's are close to the 1000 mAh, the AA's are way off the 2600 mAh.

So there is a trade-off of some mAh for these inexpensive batteries in that they wont last as long as better brands but some may find this okay given the cheap price.

In this update, I have increased my ratings by one star (from 2 to 3 star ratings) since my original review was based only on the AAs and I have now had time to refresh the AAA but I still take stars off for the misinformation about the mAh ratings.

The best NiMHi AA & AAA's I've owned yet
This marks the 3rd time I've completely replaced (recycled) and restandardized all the rechargeable batties in my house (the prior being the radio shack 1,400 mAh gold & black, followed by the 1,800 powder green white-tops & 2,000 metallic green black-tops). The new Tenergy 2,600 mAh powder blue black-top AA's seem to be the best rechargeable AA's available (as of this writing). With every generation, the run time of NiMHi's gets closer and closer to disaposeable alkaline batteries, and the blues are the closest yet. Not only do they have a deep charge, but they also seem to hold onto their charge, when not in use, better than earlier generations of batteries.

I use them in everything, and couldnt be happier ... and coupled with a Tenergy "Speedy Box" smart charger, I'm a doubly happy camper.

NIMH Batteries
These batteries were the best price I could find for Ni-MH batteries, and they typically are rated on the higher end of the voltage ranges rather than the low end that Duracell, etc. may sell batteries at. The 8 AA and 8 AAA pack has worked wonderful for me as well, because most of my gadgets use the AA, while all my home remotes take AAA, so you don't end up having useless batteries lying around.
