What Batteries?
Sanyo Eneloops, 7dayshop Good To Go, Uniross Hybrio...
I think Panasonic and Duracell have comparable offerings now too.
7dayshop Good To Go are the cheapest, and I can vouch that they're a good choice.
If you're using your camera for large amounts of time in one go, then as high a capacity as possible. I think 7dayshop do 2900Mah variants.
If you can't say something nice about Pentax, you won't say anything at all.
Apparently.

A leading consumer mag ( you know WHICH one i mean) just tested a load of rechargeable batteries. The best were Maplin 2100mAh pre-charged at £10.99 .Boots 1300mAh came second, Energizer 2650mAh at £12.99 came third but lasted the longest of the 3 at 8.4 hours on high drain so these would be my choice.

Depending on usage of course.
Plus you could get 3 sets of the 7dayshop Good To Go (precharged) batteries for the price of those Energizers.

Maplin ! It will depend on where they sourced the batch from. A lot of "own brand" batteries will vary batch by batch as they shop around for the cheapest price or who has spare capacity. I have seen batteries in Poundland at £1 for two and they were cells from a reputable brand with a different label.
How could a Boots 1300 mAh set come second? Half the energy of te Energisers and probably more than half the cost.

I generally take Which? magazine's findings with a pinch of salt.

Price was ignored.
They tested the actual capacity compared to the stated capacity (sony/philips did poorly here) Charge retention (Maplin Pre Charged Hybrid 2100mAh retained 91% of its full charge after 28 days . The batteries were tested with a Camera taking 20 shots with flash then after 30 mins rest repeating the process (Presumably repeated until the battery was depleted) . Capacity accuracy made up 65% of the score and Charge retention 35%. They also tested for risk of explosion from short circuiting.
I agree the Energizers would be my choice from the 15 batteries tested. I have been using Duracell rechargable ones for the past few years and i have been happy but they are beginning to get a bit tired and due to be replaced in the very near future.

Eneloops which my uncle has also work great, if you don't drain your batteries in 3 weeks these would be my choice or else I would go for the Varta.
