I recently needed detailed discharge curve info on alkalines, and was
staggered to find that Duracell couldn't supply anything othr than a
couple of reference curves at specific loads & temps. Surely these
guys have been making batteries long enough to be able to supply a
simple program which would give a discharge curve at any given load &
temp (i.e. what the customer really NEEDS) - apparently not! We had to
spend a lot of time testing, as we had to provide a lo-bat warning
with a specific amount of running time available (due to the standards
the product had to comply with). Lack of info was a REAL pain.
