I find the Energizer 2500mah double A batteries have major problem that
causes them not to hold a charge. When I require the use of these batteries
I find they are dead after only a few weeks of shelf life. The Energizer
2100mah cells are great with no problems what so ever and ...

Some years ago, there was an article in an electrochemical
journal, describing how to do fractional differointegration
via the Fourier transform. I have unfortunately lost the
reference. Can anyone remember it?

What is the point (voltage, deltaG) at which metal ion start migrating,
is this independent of the metal type or is this a function of the
electrochemical series?
Decomposition of water starts at apx 1.23V, does this signify the point

Does anyone know if the capacity of 2700 mAh refill batteries loaded in
a 1800 mAh loader (smart loader: stops automatically) is fully used? in
other words: are these batteries filled completely?
From resellers i got the strangest answers, but always they say: "you

Two questions regarding AA batteries:
1) At what voltage should a 1.5V alkaline battery be considered as end of
life and replaced?     I've noticed that with Duracell at least they start
out life around 1.6V, and I have been assuming that for most applications

Hi.  I am trying something at home for a cordless phone.  
The rechargeable battery in the cordless phone is a
3.6V, 750 mAh.  The size is same as 3 AAAs.  I am
thinking of using 3 rechargeable AAA batteries to
