Pros:
1. They are much, much cheaper than others in the market.
2. Even if they are overrating the AA ones [see below] all that means that I will have to recharge them a little sooner. I am willing to take that over paying $ 3 to $4 per cell for other brands!!
3. AAA ones measure nearly 1000 mAh! They are rated at 1000 so they are good!

Cons:
I have a high end charger from Maha - MH-C9000 WizardOne Charger-Analyzer . It is able to tell exactly what the capacity of a battery is. I have tested at least 7 or 8 of my 25 or so Tenergy AA batteries. All measure around 1500 - 1600 mAh. Note that these batteries were bought in the last year or two. They are not brand new.
I even did many refresh cycles , even after a couple of break-in cycles [that is supposed to recover under used cells] the capacity does not increase.

Hence I can say for sure....they are overrating them.

By the way, my 3-4 year old energizer cells [2500 mAh] from Costco also test around 2000 - 2100 mAh on my analyser. So maybe age is a factor. But at least the energizers are closer to the 2500 they claim!
