Best AA size Battery Required

I have just remebered the name of the new batteries I saw on the telly.
Energiser lithium.

Personally I think that if roddydogs is having problems, it's due to either fake batteries from ebay, a rubbish charger (not microprocessor controlled, with “Delta-V” circuitry), or possibly a faulty camera. I have an Olympus that works fine even after being left on the shelf for months but I always take a spare set charged up when I use it.

chargers are FujiFilm by Hahnel, and Uniross(Argos) with timer which came with batteries tried both, tried the uniross baats that come with it, Fujifil Batts1800 that came with the charger

Enelops dont appear to be other than 2000mha, read Buglawtons post and links

Agreed and I have read the links. The batteries that you have ordered may have a better charged shelf life, however their capacity is less than disposable alkaline batteries, so they are unlikely to perform better.

To get the best out of NiMh rechargables, as previously mentioned, a good quality charger is required. Chargers with a timer are basically crude and useless to get the best storage capacity and life.

Hey - I don't agree with that! When I put a brand new set of Alkalines in my Casio camera I get about 10 pictures before the camera switches off. I wondered why as they can still power a torch perfectly afterwards. Reason is that although the alky's have plenty of charge left, it is all at below some threshold like 1.2v. A set of Nimh's by contrast gave 100 pictures & more, because they held their voltage. To some extend it depends on your camera... this factor has more affect on apparent battery life than most people realize. The 'fall-off" curve on voltage in alcy's is even more drastic than Nimh's under a heavy load like a digy camera.

Well I have never used Sanyo Eneloops but then I have never had a problem using NiMh and a good quality charger. The main advantage of these Sanyo Eneloops is their shelf storage life, not their capacity.

Whilst were on this, 2 Multimeters good for measuring battery life, Maplins £5.99 BOGOF ie less than £3!

Go on then, how do you propose "measuring battery life" with a multimeter?

:rolleyes:

Sorry , voltage

I have to agree with espresso here. I just don't understand why anyone would want to spend substantially more money on a battery that has less capacity and its only advantage appears when you leave it lying on the shelf.
buglawton states "You should read this review which explains why an apparently 2000mAh battery Eneloop battery would outperform a standard 2500 mAh one" I can assure you that testing done by someone who made the "test equipment" in his workshop would hardly instill confidence in me let alone stand up to scientific scrutiny. A rough guide and no more than that.
And I think buglawton has shot himself in the foot with his other two links which show that for .5A, 1A, 2A and 3A the "normal" 2500mAH NiMH batteries last approx 25% longer. Does buglawton really expect me to believe that the whole of that 25% is below his 1.05V threshold? I think not.
So to conclude:- Do I want to pay extra so that I can leave the batteries on the shelf for longer? I think not. I charge my batteries to use.
Do I want to pay extra for batteries that don't last as long? I think not.
Do I want to pay extra just to say I can use these batteries as soon as I get them instead of the next day? I think not.
I rest my case.
