No, it shuts down, but the meter read full the day before. The dropoff
on a LI-ION battery is rather abrupt, it would seem.

Yes, it's not just high-end cameras that use Li-Ion, the tiny cameras
really have no choice but to use Li-Ion because of size and energy
But on the non-tiny cameras, you'll usually find that the higher-end
ones use Li-Ion, and the lower end ones use AA's. There are exceptions

We have only Motorola cell phones, and the battery meters work just
fine. However there are instances where the situation you describe
happens, even with a good battery. It's especially an issue if you keep
your phone in a place where it can't get a good signal. I.e., my wife
would stick her tri-mode phone in a metal desk drawer, where it would
either switch to AMPS and quickly run down the battery, or if it could
get a digital signal it would increase the power to compensate for the

The number of shots per set of batteries is not the issue at all.

In fact, one of the advantages of Li-Ion is that they are so forgiving
of lack of use.

True, but the OP wanted to know what type of AA batteries to use
in a Canon A70 that gets little use, which is the issue. The
correct answer is alkaline or the new low self-discharge NiMH
batteries. The older NiMH batteries could still be used, but they'd
be slightly less convenient since they might need to be recharged
first if they haven't been charged for over a couple of months. If
a large percentage of the shots need to use the flash, then any NiMH
type would be preferable to alkaline batteries. The A70, btw, is
one of the cameras that can get well over 1,000 shots per charge,
even from the lower capacity, low self-discharge rate Sanyo Eneloop
and RayOVac Hybrid NiMH batteries.

In fact, you're just spouting your usual Li-Ion propaganda. Due
to their relatively low self-discharge rate, Li-Ion batteries are
pretty good if they often go several months between charges. But
push them too far, such as more than 6 to 9 months between charges,
and unlike other rechargeable types, Li-Ion batteries can fail and
may need to be replaced. The low discharge rate NiMH batteries can
still be used after a year or two since their last charge, which is
attested to by the fact that they're sold pre-charged. That is,
unlike Li-Ion batteries, they can remain on a store's rack for over
a year, and can still be used immediately after purchase without
needing to be charged.
