Use normal AA batteries (non-rechargable). For your usage pattern that's
the best option. Not to mention that you can just try it without buying
any new stuff.
Or try the new Sanyo Eneelops with low self-discharge rate. However they
are expensive and require a new charger, too.


The new low-discharge "pre-charged" NiMH batteries do not require a new
charger. And if you don't buy the Eneloop brand of these types of batteries
then they are no more expensive than normal prices you've paid for NiMH
batteries in the past. The only reason Eneloops are higher priced is
because that's the only brand-name that online parroting trolls, who don't
actually buy batteries for their imaginary cameras, know of to spew
constantly. Since everyone thinks that Eneloops are the only brand or
somehow better, then Sanyo gets to rob everyone blind. Such is the folly of
following online troll's advice. Eneloops may have been the first kids on
the block but that's not been true for almost 2 years now. Nor are Eneloops
the best anymore. Though you'll never know this by listening to online
trolls' parroted advice.

You are also wrong about advising them to use normal alkaline AA batteries.
Digital cameras require high-current rates, but for very short durations.
Regular alkalines will only be useful for a very short period of their
typical life-time in all other devices before their voltage drops below a
useful level for digital cameras. A *huge* waste of money for a digital
camera. NiMHs or Lithiums (if your battery can deal with the slightly
higher voltages of Lithium AAs) are best for all digital cameras.

Please stop spouting advice on a topic that you obviously know nothing
about.
