A Lithium battery warning question

Just bought a vertical grip/AA-battery pack for my Canon Elan II. Came
with a warning to use Alkaline NOT Lithium AA-cells. Why?

Lithium batteries have a higher voltage (1.6 vs 1.5 for alkalines), which
may damage your equipment.

Whatever the reason, not using lithium largely defeats the purpose of
having battery packs in the first place.

To both the OP and Anthony, what about Nickel Metal Hydride?

Lithium cells have a lower internal resistence which allow a higher
current flow. This is may be a good thing but they also get hot under
high current draw. If you shoot your frames in single mode no problem.
But if you hold the button down for those rapid sequence shots, those
cells could get hot enough to damage the plastic battery compartment.
Maybe even over heat other electrical parts. I use them in my F100 and
my SB28. I have had no ill effects what so ever. Nikon does advise you
to allow a cool down period between sequences if you are using them.
But then I am not exposing a roll of film in 9 seconds or less either so
for me they work great.

Thanks for the response. Does anyone know if lithiums are ever prone to lead
like alkalines?

Lithium batteries don't leak. They have a shelf life of over a decade
without any loss of power.

Just as an aside: the AA grip for the Pentax MZ-S has a little switch to
select either Lithiums or alkalines - presumably the voltage issue is the
reason. I don't know if any other grips do this, but it seems sensible (or
just put in voltage sensing circuitry).

The issue of Lithiums heating up with very high current draw never bothered
me as the only things I use where it might be an issue - big flash guns,
packs for high speed drives - I power off rechargeables anyway.

The great things about Lithiums - for me - are the low weight, long shelf
life, and greater immunity to cold.

In addition they hold their performance at much lower tempertures than
any other battery. Not that I am some artic exploreror. But its nice
to know if it gets cold out, they will still work for you.
