I've used the Aldi ones for about a year and find them really good. I was suprised that at my Aldi at least all sizes were the same price, AAA, AA, C and D. I have the whole range and several sets each size. I use them in torches and particularly my Nikon flashes, SB800/900. Have no reason to complain, they seem good.
I do charge all my batteries in an expensive charger though with circuitry control on every circuit. The charger refreshes and conditions the batteries each cycle. I do recommend a good charger, after messing around previously with £10 and £20 chargers from the likes of uniross etc. and batteries failing or having short lifespans the chargers by the likes of Annsman are a revelation. Typically they are around £50 but you see them rebadged cheaper and even Aldi occasionally do a good one of their own.
ps. i meant to say, in many aldi's in my area. leicestershire i notice that these rechargeable batteries seem to be disappearing and several stores just have alkaline. Maybe they are having difficulty sourcing batteries although the xmas peak in electrical sales may bring them back.
