In what way? I've noticed no difference between the 7DayShop ones and the Eneloops I've got.

They (Eneloop) last a lot longer in my digital camera before the voltage drops low enough to cause it to shutdown, good batteries maintain a higher voltage over their discharge rather having a higher capacity at the expense of a lower voltage. The below graphs should explain better

My experience of cheap batteries is that even if the initial capacity is high, it seems to decrease quite quickly with repeated use.

Eneloops are lasting a lot better.

I used to use 7dayshop but found them to be inconsistent I now use GP from Battery Force

My favourites are Eneloop and Ansmann (not their ultra-low self-discharge though).
The Ansmann 2400 worked out at the best value at the time.
7dayshop's own brand have all now failed over the same lifespan (4 years). Threw the last one in the recycling bin last week.

Recently, I've just been buying Eneloops, but I'm wary of ebay, because faking Eneloop would be an easy way to make money.

The own brand ones are slim so fit in torches easily

Exactly the opposite - they're slightly fatter than regular batteries and get stuck in torches.

You are correct they are fatter than regular batteries. What I meant however was that out of various rechargeables that I have bought these are slim, especially under 2400 size. Duracells for example would not fit in my torches.

As a note Aldi ones are slim also.

I'd suggest the amount of claimed difference in that review is pretty negligible for most people in real world applications anyway.

Oh, sure. One man's 'test' doesn't give us anything conclusive, and a capacity difference of a few percent is neither here nor there of course. I just thought it was interesting, really. Uneven charging or no, the reviewer seems to be of the opinion that the 7DS ones are universally poor; quite a few people here would seem to disagree.

Pay your money and take your chance, at the end of the day.

Another 7day shop recommendation but bear in mind:

That's not my experience Cougar, and I have the fancy charger that can measure capacity etc. some of the Eneloops I've got were well under claimed capacity.

I'd suggest the amount of claimed difference in that review is pretty negligible for most people in real world applications anyway. I'm also not convinced testing one set of each is giving you enough data to draw real conclusions, and the charger he uses is one where I've seen complaints about uneven charging.

I read a review years ago in a camera mag and the 7day ones matched the Eneloops ones almost perfectly in tests and marginally beat them in one, I only ever use 7day ones.

I always use Strikalite
