The camera is a 6 year old point-and-shoot Nikon Coolpix 2100 (2
megapixel) that uses AA batteries. I have been using rechargable
Energizer NiMH batteries, 2500 mAh. My problem is that the batteries are
almost always dead whenever I need my camera;


Yes, normal rechargable batteries have a high self-discharge rate, even
when not used. And they age. After 6 years I would expect the battery to
hold only a fraction of what it used to hold when new. Plus the deep
discharge every time is not a life-enhancing scenario, either.

They seem to be drain within a week or so.


New rechargable batteries should last significantly longer, typical NiMH
should loose about 1/3 per month.

I bought rechargable NiMH batteries because I was told digital cameras
would deplete other batteries too quickly.


Well,almost true. Using batteries instead of rechargables will deplete
your wallet if you have a standard usage pattern for your camera. You
don't.

Given my usage patterns, should I be using a different type of battery?


Most definitely yes.

I want something that will hold its charge (for the long periods when the
camera is not being used)


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.

but will have enough juice to get me through a
week or two of vacation when I do use the camera.


That's not going to happen. If you _actively_use_ the camera daily then
no batterie will hold enough charge to last that long.

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.

Oh, I see you found a new field for your rantings because nobody was
listening to your P&S versus dSLR nonsense any longer.

Is that the only kind of red-herring reply you can come up with when anyone
has easily proved you 100% wrong? Is this the only way you can refute being
exposed as an ignorant troll who is spouting major misinformation (a good
moniker for you, Major MissInformation) because you clearly know nothing
about cameras and the batteries they use? Which now shows everyone how much
credibility you'll ever have about any cameras at all.

No need to reply. You had your chance. It didn't work. In fact your reply
made you look even worse. No doubt another reply from you will do the same
for you, only worse yet.

I know, try highlighting typos or grammar errors for your next reply. Then
you'll be clearly displaying both of the most important and obvious
troll-feathers in your cap.

Go crawl back under your rock. Your exposure to some light is starting to
peel your scales away.

Do you have a reference for "requiring a new charger"? I've been using my
standard "1-hour" NiMH charger for the last several months with no
problem.

You're correct, the Eneloops do *not* require a new charger. When
they were introduced (first the Eneloops, followed several months
later by RayOVac's Hybrids), and before Sanyo started packaging
chargers with some of their Eneloops, the packages said that any
standard NiMH charger could be used. In fact some of Eneloops
chargers are sub-optimal. They're all very slow, but some of them
also lack individual charging circuits,only charging cells in pairs.

Hmmm, good to know. I didn't have a NiMH charger and was certain that I
couldn't use my old NiCd-charger, so I had to get a new one with the
Eneloops.

Yes, NiCd and NiMH /do/ require different chargers.

No, it all depends on their mAh output. If the NiCd is charging at a 200
mAh rate or less, then there's no need to get a new charger if all you have
is an ancient NiCd charger. Yes, it will take longer than the amperage that
more modern NiMH chargers put out and charge the batteries more quickly,
but a constant 200 mAh charge on NiMH batteries will not harm them.

Many NiMH chargers keep a sustained 150mAh charge on batteries after their
initial full charge to circumvent their internal draining resistance
(self-discharge rate).

I'm amazed at the amount of ignorance being displayed by self-appointed
"pros" in this newsgroup.

200 mAh is a capacity, not a charge rate. I agree with you with on the
ignorance been shown.
