<p>-Yes, I saw that the second part of that sentence relating to the total energy is correct, and I also immediately saw the reason for that as being equal to the power curve time integral when the constant current is brought back as a multiplier within the integrand. I commented on the total charge formula being correct as well, but under an "anonymous" entry. But all this is very basic, really.
-There is a little more to why alkaline batteries perform better with low consumption, and it is not the low self discharge rate. These batteries simply have a highly variable capacity under different loads. Most AA alkalines will easily surpass the 3000 mah mark in low consumption applications, while can only muster 1/3 of that at the 1 or 2 ampere drain rate. If even that. So, even super low self discharge Nimh batteries will perform poorly when compared to alkalines in low drain applications.
I think that in an article such as this one has to be a little more careful with the clarity of conclusions reached and the logic of making inferences from the experiment alone. Otherwise, what is the point of going into the detail of the entire setup and obtaining the data. Not to be critical, really just want to be constructive...</p>

<p><strong>Emery Polan</strong> thank you for your comment, these moments definitely need a better explanation. Alcaline batteries are more suitable for low consumption devices because of high self-discharge rate of most Ni-MH batteries (low self-discharge Ni-MH batteries are out of scope of this article). And you're right, the calculation of the integral of the voltage discharge curve by itself doesn't make any sense, but the integral of the voltage multiplied by discharge current does. Since the discharge current is constant, it can be separated from the integrand and instead multiplied by the integral of the voltage discharge curve.

<p>I wonder how did you reach the conclusion about alkaline batteries as being better suited for low consumption devices. Granted, this is quite true, however this fact can certainly not be based upon the experiment described in your article. Have you examined the capacities of various types of batteries under various types of load? Obviously not.
Second,the calculation of the integral of the voltage discharge curve will not give you the charge capacity. Why would it? Total nonsense.
I suggest to You a more careful approach in publishing experiments and the conclusions that may follow.
Programming and hardware inter-phasing is a very excellent skill to have,but basic theory on a scientific level is equally important to master. Or at least to manage.</p>
