Duracell Plus (aa size) 8 + 8 Free = 4.91

misfire

At tesco - was labelled as more on the shelf but scanned at 4.91p for 16 AA duracell plus - i thought that was really good!!!

Much better to buy rechargeables - both for your pocket and for the environment. And do Duracells really last significantly longer than own-brand alkaline batteries? Remember that the TV ads you pay for when buying them always compare them with non-Alkalines so mean nothing at all.

I want to buy rechargeables for both my digital camera (Canon Powershot A430) and Creative Zen MP3 player. Please could you tell me what the difference is between Ni-MH and Ni-Cd batteries and which ones I need as I am not too sure.

Thanks.

And sorry OP for hijacking your post.

Ni-Mh (nickel metal-hydride) and Ni-Cd (nickel cadmium) refer to the chemical composition of the batteries.

In REAL terms it referes to the capacity of the battery, and indirectly refers to how it performs. In real life use, a NiCad has a far lower capacity than NiMh, and has a 'memory effect' which means that to get maximum life (and recharges) out of them, it is necessary to completely flatten them and completely recharge them every time.
A Ni-Mh has far higher capacity (more time between recharges, more shots per charge, or more tunes per charge!) and don't suffer this memory effect, so you can recharge your battery after 30%, 50% or 70% use without harming it.

A NiCd CAN be recharged more often, a NiMh can usually only be charged about 300 life cycles, (NC more like a 1000) but the real world practicalities make NiMh a far better choice

For use in a camera, I presume you will need AA size, you should be looking for very high capacity ones, like 2400mAh or above.

I agree with the above, but with a caveat: the claimed capacity figure of rechargeable batteries is about as good a guide to their capacity as the brand of alkaline batteries is to theirs, i.e. not very. Just go for NiMH and don't worry too much about the stated capacity.

That's really helpful, thank you, I'm off to buy some now.

Checking from ebay too. I got such a good bargain of rechargeable batteries from ebay. Choose the reliable and power-sellers.

Robert Dyas are doing 10 + 10 Duracell for about the same price

I always get my batteries here http://svp.co.uk/products-list.php?cid=28, only when I'm buying other bits and pieces to save on postage but it pays to stock up. Especially handy for toys around Christmas and birthdays. :-)
