What Batteries?

Just a general question. For all those using rechargeable AA batteries, what is your brand of choice? I've been using Sony 2500MaH batts in my K100D Super for three years now, but they are starting to go flat rather quickly now. I'm also trialling Eneloop 2000Mah batts,: not bad, but obviously don't have the same usage time. I'm currently awaiting delivery of some Powerex 2700Mah batts. Does anyone have any favourites??

Depends on your usage. If you use your camera a bit, then leave it for a couple of weeks, then come back to it etc. any of the Ni-MH low-discharge typeswould suit you:

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.

I'm using Varta Pro 2700mAH batteries for my flash and they seems to be good.

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.

Eneloops here. All my old 2700 Sanyos will be replaced over the next 12 months with them. I don't care about the headline "less capacity", I've seen the results and they keep their charge magnificently.

I've a set of Eneloop rip-offs from the 7 day shop (recommended on this site) but have never used them as my Energisers are like a modern day Widow's Cruze of Oil: I must get 1000 shots out of a charge and I check the screen after every shot (don't use the autofocus or flash much, though). One huge advantages (inter alia) of the K100.

Btw there are new versions of Eneloops I believe, they are rated fro twice as much recharge cycles.
Like I said "I believe" so I ain't sure.

I use Eneloops with K200D and am very satisfied ... had tried Hama 2700's but with limited success ... Eneloops supposedly retain the charge better during periods of low use as well (low discharge rate)...
