Rechargable AA's...

produce an empty blinking battery icon in the LCD window and nothing else. Do the batteries have to be brand new? Auto detect along with manual selection was used with the same result.

I have been using Sanyo Eneloop's for years with KX, K7 and now with K5 ( last two obviously with batter grip D-BG4 ) with no problems at all.
you can not use low quality AA ( like Ni-Cd) with DSLR's, they can not cope with high power demand.

Just get yourself some Sanyo XX. Those Energizer 2500mAh are no good at all.

depends on the usage, budget and requirements
the Sanyo XX are 2500mAh but it retains 75% capacity after only 1 year, rated for 500 charges
Sanyo Eneloop are 2000mAh, it retains 75% capacity after 3 years, rated for 1500 charges

my experience

i've tried duracell rechargeables, eneloops, rayovac hybrid, and sonycycle energy NIMh's in my K100dS and Kx.

the rayovac hybrids worked best, they would last forever.
the sony ones did well (the 2100 and he 2300-2500 both seemed to last about as long)

the duracell and eneloops both lasted noticably shorter.

most important is to get a smart charger (that senses how full the batteries are and can drain them before a charge), not the cheap timer one i felt.

now that i have a K5, i just have a ton of batteries sitting around though.

Lol, me too, though I bundled some of them with my K-x when I sold it.

Time to get myself a hotshoe flash I think.

I've used the Energizer rechargeables for a couple of years now in my K-x bodies, and also in a K100D & *istDS with success.

Before I knew better, I did have a problem with the 15 minute quick charger prematurely killing off batteries, but since I wised up & bought a Maha MH-C800S smart charger, I've had no issues.

The Kodak 2500mAh "precharged" NiMh batteries also work well and last several hundred shots per charge, but the battery meter tends to say they're low long before they actually are. I just use 'em 'til they conk & then replace them with a freshly charged set.

This sounds more like a problem with a specific set of batteries rather than a brand. In my experience all brands I have tried worked at least for a little while. If you are putting them fresh from the charger into the camera they should work at least for awhile.

Try the batteries in something else, AA flashlight maybe.
Do you have an intelligent charger? This is supposed to help get a proper charge.
How old are the batteries? As noted above Eneloops seem to keep recharging forever but the ordinary 'rechargeable' brands do wear out. For example, when I bought my k-x I bought 4 sets of batteries, 2 Eneloops and 1 Energizer and 1 Panasonic. The Energizers are long gone, the Panasonics are powering my computer mouse and only last about 2 days before needing recharged and the Eneloops are still going strong in the k-x.

If those batteries have been around awhile with numerous charge cycles they may be worn out or one of them may have an internal fault. My charger goes through a test / de-charge cycle and will alert when it finds a problem with a battery.

They've been through the wringer a few times and are mainly used for the remotes. I can't seem to find the dedicated camera charger's(yes, I've lost both).

Stay away from Energizer NiMH's at all costs. They have an incredibly high self discharge rate and the internal impedance sky rockets very early in their life making them useless for high power applications. I've got some of the 2500's and they barely run my POS point and shoot for 20 shots. Get the Sanyo anything's as they have a much more modern chemistry with practically no self discharge (compared to other NiMH chemistries anyway).

I forgot to ask, but I assume other battery sets do work properly? So we can eliminate a camera problem?

If so, then it's time for a new set. As noted the energizers do not have a good reputation with high draw applications. I used to think all batteries were pretty much the same but a little research shows different brands have different chemistry's and internals, so some are definitely better. You might have one cell with an internal fault, not worth messing with, toss 'em and get a new set.

I was using energizers in my flash triggers (AAA) but since I don't use those everyday I found every time I went to use them the batteries had drained. Bought a set of Eneloops for them and have not had a problem since.

Try your local price club. I got a good deal on 8x AA, 4x AAA, and a trickle-charger as a pack from Costco about a year ago but they don't seem to carry them at the moment.
