Sorry Vmer, I was joking a little bit there.  Basically, how long do the
batteries really have to last?  I just saw the Tadiran website you listed in
another email.  These look like a different breed of battery from what I'm
used to seeing.  I'm not sure that increasing the load will give you much
information as far as projecting what you can expect from a real
installation over the full length of the real time discharge.   Why not just
take the curve  from the battery datasheet for your current consumption and
derate it a few percent for a safety factor. Real world longevity will vary
a bit depending on where the device is installed anyway.  I guess the only
real way is to set up a bunch of these and see how long they actually last.
