There seems to be a price premium for the highest capacity NiMH
batteries (2700mAh) - are they really worth it? It's a bit like the
price premium of the highest capacity RAM DIMMs, whatever they currently
are.

Any recommendations for NiMH AA batteries that suffer least from the
wretched self-discharge effect?

Possibly if you have a high power requirement where you can be sure to
fit freshly charged cells to the equipment before use.

anything that says it's precharged when you buy it, e.g. Eleloop,
CycleEnergy ... but almost every manufacturer has their own version,
usually 2000 or 2100mAh ... I've replaced all my MiMH with the low self
discharge ones now.

The lidl pre-charged ones are OK and only £3 for four AA cells.
They still have them in my local Lidl.

Like all the other pre-charged ones I have seen they are only 2100 mAHr.

I've been trying the Lidl own-brand LSD ones, yet to see how good they
are. Over the past two years I've had several Vapex Instant LSDs from

http://www.component-shop.co.uk/html/aa.html#IN2500AA and they've

been fine. I tried Eneloops, but didn't find the extra cost to be
worthwhile over Vapex.

2.7Ah NiMH in my camera managed only a few shots before the camera cut out
on low battery.
On Eneloops it does c. 200 shots if about a quarter are with flash and also
the Eneloops can be carried as spares and are useful even a year or more
after charging.

Well if it was fully charged then it was faulty. I don't find any
advantage in using the LSD ones in the cameras. We use it so much so the
batteries get used up (as in within a week or so) before they self
discharge. So I have higher capacity ones in there for as long a run
time as possible.

But for general battery use I find LSD ones much more convenient.

On Eneloops it does c. 200 shots if about a quarter are with flash and also
the Eneloops can be carried as spares and are useful even a year or more
after charging.

Yup, I mostly use the 7 Day Shop ones, they seem perfectly fine. I've
also got Eneloop, Anmsmann Max_E and something else, can't say the extra
expense for the brand names ones seems to give any obvious benefit.

A very considerable premium. D cells are available with capacities of
11,000 mAH but are very expensive.
Probably AA cells could be made with capacities of around 4000 mAH but
wouldn't sell.
The D cells with capacities of around 2200 mAH are just C cells in a D
package, as can be told from their weight.

There are none that I can afford.

Yes, my experience also. In fact the high capacity NiMH batteries
wouldn't even drive my old digital camera any longer and I was about
to throw it out when someone suggested I try Eneloops. The problem
with the(some?) high capacity NiMH is that they have a high internal
resistance.

Usually the reverse actually.

The problem with NiMh is is flattens itself in hours whether its being
used, or not.

Thanks for all the suggestions, I'll try some low self-discharge ones
and not worry about capacity.
