I've always wondered who buys them and why?

They have a niche market for long self life seldom used products
that
must be "ready to go" when needed. e.g. torches, GPS receivers, UHF
radios. You'll also often get longer operational life than NiMH, and
that can be handy in many situations. They also have benefits in low
temperature environments and are lighter in weight, so are popular
with bushwalkers and climbers for example who count grams and might
have to use them in freezing alpine conditions.
As for cameras, if you only take a few hundred shots a year then
they
are actually a pretty good choice for that.

Being "ready to go" without ever having to remember to charge them,
and longer potential life under more adverse conditions are very
useful benefits that can (for some) far outweigh the extra cost or
lack of eco-friendliness.

Also, be careful when you start comparing capacity, it varies a LOT
with temperature and load. At very low temperatures the Lithium can
have several hundred percent the capacity of an Alkaine and may
actually be lower in cost if you talk $$/Wh

Dave.

Good points. Lithiums have formidable shelf life and operational
temperature range, as well as handling severe loads.
I used them in my Olympus digital cameras when the memory backup
super
caps died and they'd lose all their settings the moment the battery
was
disconnected, to minimise battery swaps. I really noticed the drop in
weight.
Then I found a source of backup caps and replaced them, and went
back
to using NiMH.
9V lithium batteries would be good in smoke detectors which are
hard
to
get at.

And maybe good in mutlimeters. I seem to be forever replacing
alkalines,
but
then again perhaps I should remember to turn them to "off" before
putting
them back in the case.

Or simply get one that has auto-power-off.

Dave.

A Fluke 73 and a Fluke 19, they both have a power off feature, or more
appropriately a sleep feature.

James

Ive got the same two meters. the 73 doesn't go through nearly as many
batteries as the 19 though. the 19 also seems to crash alot - it'll lock
up
randomly, maybe a couple of times a month & i'll have to switch it off &
on
again. never happens with the 73.

the 73's probably got a better sleep feature than the 19 i'd guess, they
both get about the same amount of use.

cheers,

timbo.

Oops...A bit quick on the send button.

I prefer the 19 to the 73 for most things. I've never had any problems with
the 19 locking up or anything silly like that, and believe it's exceptional
for the price (although maybe not a "proper" Fluke meter). The one thing
that does give me the shits about the 19 is the lack of beep on diode check.
I much prefer the short beep for roughly checking diodes & transistors
without having to look at the display.

The 19 appeared to be a fantastic value-for-money meter when they
introduced it for the asia-pacific region many years back, it was not
sold anywhere else that I am aware of, it was a trial to see if a
cheap Chinese made Fluke would sell.

Every single unit I have used (at least a dozen of them) have died
either partially or completely. Horror stories abound, the failure
rate was massive, I'm surprised there are any left that are still 100%
functional. It also had a common bug/fault that drained the batteries
flat in no time.
It didn't last on the market very long, and was replaced by the 110
series.

Dave.
