Which battery for Pentax Kx?

I currently have a set of Maplin 2000mah Nimh battery that I used once in my Kx and for some reason, appears to deplete quickly (Software updated by the way).

I have seen people recommend the Sanyo Eneloop, but this only rated at 2000mah (same as the maplins brand) is it really worth buying this as I have see a 2500mah rated ones at maplins and at a cheaper rate. What do you guys recommend please? Is there any other brand I may want to look at etc. Thanks.

You want me to use the Ni-zn he mentioned in the link? ????

I would certainly recommend the Sanyo eneloop, I have 2 sets for my Ds (1 spare set kept fully charged). Not a clue what the shutter count would be but they seem to last for ages.

As I don't use a camera that takes AA's I've not kept up to date with RH's ramblings. Last time I looked he was recommending Japanese made Ni-Mh by Panasonic. I've used them in an *istDS that I used to have and they were excellent. I still use the same batteries in my flashguns. Unfortunately I think the Panasonics now sold in the UK are from China and not as good.

Eneloops might be the safest bet even though their capacity is only around 2100MaH.

Energizer Lithiums are good if you don't use the camera a lot.
Sainsbury's were doing them for £3.99/4

Once?

Are they new? If so, they can take a few cycles to give max power/life.

Depends on your usage, if you drain the batteries in 3 or 4 weeks get the higher rated ones. I've Varta for my flash and they are very good but not really cheap though.
If you do longer with your batteries get Sanyo Eneloop or similar because they hardly drain themselves and after 4 weeks is roughly the turning point they have more power than the normal NiMh.

Ni-Zn are different batteries, they have a higher voltage but you can only get them in the States for now and they can damage devices.
If they can handle Lithium batteries it should be safe to use them.

Thanks guys. I opted for the newer version of the Sanyo Eneloop at the end, I will post back to see how they fare.


@polchraine

I used them in my previous camera so may be age is a factor, had them for over a year or so now.
