AA Batteries: What do you use?

LiMH? Alkaline? Li-Ion?

I used to used LiMH, but i had too many battery sets fail from overcharging, and was constantly annoyed with batteries that drained just by sitting for a month.

Lately I have just been buying bulk packs of alkalines at costco, but ive gone through a few 48 packs already (my daughter, who absconded with my first k100D), helps alot in that regard; interesting side note, she is 15, and does not get why i geek out over old non autofocusing lenses; 95% of the time she sticks with the kit lens, though i did give her some longer pentax AF zooms)

i have a set of low discharge LiMH batteries, but if i go that route i probably need to buy a smart charger with an automatic conditioning cycle, and the charger alone costs about 100 alkalines ($28), and the better LiMH batteries themselve are about $10 a set of 4.

what do other people with K100Ds or K200Ds do?

See the sticky thread at the top of the Beginner's forum, which is where I'm moving this thread too. You'll see it's virtually unanimous for Eneloops or similar hybrid / low-self-discharge NiMH. These can be used in "normal" chargers, although you do want one that shuts off automatically. Alkalines are close to worthless; by far the most expensive and environmentally unfriendly solution possible. For $35, a decent charge and two sets of alkalines will be all you need for *years*.

EDIT: looks like the sticky thread I mentioned has been moved to the "accessories" forum. I wouldn't have looked for it there, either. I'll see about moving it back.

Didn't even know what Eneloops were until I came here. I went and picked up a few sets and cannot believe I wasted so much time recharging my old batteries every week.

Eneloops work great in a D-BG4 grip BTW.
They have more A$$ than d-li90

I was kind of disappointed when I tried this. Mine didn't last very long. I could have a weak battery in the set and my grip is the generic one. The rechargeables also weigh a lot more than the proprietary battery.

Bought this off eBay and impressed with it. The cells are now MIC but seems to last longer than the 1st gen Eneloop. It is a full featured charger with discharge feature.

I just use the Energizer Lithium batteries (the blue and silver ones, ~$10/4). They seem to last me about 5-6 months of usual use.

What do you do with them when they go dead?

Boil some soup for the children. I prefer rechargeable too even though they will end up dead eventually. If there are better ways to save the planet, I am listening.

I use the C9000 charger, all the batteries seem to be very closely matched when done charging. Grip being generic should have nothing to do with it.
I estimate around 800 or so shots per charge from eneloops in the grip. Have not done an actual test however.

I use Eneloops and Energizer Ultimate Lithiums. For flash, I use the Eneloops exclusively because I blow through batteries in a hurry. For the camera, especially when traveling, the lithiums are far more convenient that taking a charger and converters, and the AF jumps to attention when driven by Lithiums. Yes, you need to save them for special pick-up by the Solid Waste Dept, but if you won't be doing this very often. I hardly use the on-camera flash, so I get well over 3,000 exposures from the K-x on a set of Energizer Lithiums. That means I am not disposing of many battery carcasses.

I've got Eneloops and these from Thomas Distributing. I like them so well I got a couple extra sets (and some AAAs), and I'm now using them in almost all my devices.

After I use up the remaining stash of Duracells, I won't be buying any more. I cut a small hole in the top of a plastic sherbet container, and I throw the old batteries in there. When it gets full, I take 'em to the recycling place. I'll probably take 'em soon, as I also have to recycle a battery pack from my UPS....
