Longest lasting non-rechargeable batteries

I decided I'd ditch my recharageable AAs seeing as they drain so quickly and because the disposables are now probably as cheap to use (less than 9p per battery in my local bargain basement shop).

I've noticed that some cheapo batteries seem to last up to the estimated 42 hours in my Yepp MT6Z, while others die much faster. So I was wondering, which are the best ones to buy?

So far I've had good experiences with Aerocell Super Alkaline (LR6 Mignon 0% Cd-Hg whatever all that means) batteries from Lidl. The Pleomax ones (made by Samsung) I'm using now aren't faring quite so well. The battery level indicator has depleted to two of three bars after only a few hours use.

Well after researching the subject a bit more I've come to the conclusion that if you need batteries for high drain digital equipment the best ones to buy are probably Duracell Ultra M3 or Energizer Ultimate Lithium.

Neither are cheap so they don't really fit into my better-to-buy-throwaways theory.

After only two days use the Pleomax one I'm currently using is almost kaputt. Shame really since I bought 3 packs of 10. I'd like to know what's so special about the Aerocell ones. Hmm, so Cd-Hg stands for cadmium mercury. Is that good or bad?

All of those are dangerous and have to be disposed of in the hazardous waste... I'd recommend getting rechargeables. I don't know how much 9p is, here in Canadian dollars I can get a 2 pack of AAAs for $7 and they last a year or more of pretty intense MP3 player use. It ends up quite economical - I got a pack of 4 Energizer AAs for something like $14 which is roughly the same and they last even longer. There are also the enloop and other types... but from environmental and cost point of view I think rechargeables win out...

Until quite recently I was using rechargeable Energizer 2500 mAh NiMH batteries. I switched back to throwaways because they were no longer holding their charge. My charger insists you recharge at least two batteries at a time so by the time I got round to using the second battery it was flatter than a pancake. The first one dropped an indicator bar right after inserting it into my MP3 player. Really annoying considering I've not had them that long.

I hadn't heard of these slow-discharge Eneloop ones before now so thanks for the tip. They look like they might be the solution. I'd rather not pollute the planet any more than absolutely necessary.

Thanks for the signature advice too. I assumed the code would be the same as vBulletin's but that doesn't seem to be the case. Anyway I think it should be fixed now. Let's see...

Oh I forgot to mention that 0.09 GBP (9 pence) = 0.204 CAD.

Happy to help - Sucks though to have a recharger like that, I remember we had a few threads on rechargers and which ones are better and stuff. Mine lets me insert up to 4 at the same time - but I can just have 1 or 2 if I want to. It also lets me do AAAs and AAs at the same time and it was pretty cheap and good quality. There might be others out there that give you more flexibility, I know I'd hate it if I was restricted to having to do 2 at the same time always.

Those Energizer 15 minute ones look good. They'll let you charge one battery at a time. The key words to look for seem to be 'individual charging channels'.
