What are the best brands of batteries AA to use in K-X
rechargeable kind
Thanks for info

[Pauld]

I've used energizer NiHM rechargeable batteries for years in my istDL* camera and only had to replace the set once. I still use them in my flash and they hold a charge quite long. What will kill your batteries is if you use live view a lot., Powering a lcd screen that size takes a lot of power.

Hi Gusser, everybody think Sanyo Eneloop batteries are the best. I've been using Energizer, but they are not to good, I would say about 150-200 shots per charge. I received my Eneloop's this week, and will try them next week some time

I would not recommend rechargables based on the dismal performance I have experienced.
Started to use them when I got my K100d a few years ago. Had many sets of batteries. Would get a couple hundred shots if lucky on a fully charged set. Most times I'd find they were discharged when not in use. So the camera would be dead along with the spares in the bag.
I switched to Energizer Lithium Ion batteries. Get around 1500 shots on average with the K100d and the same with my K-x.
Much easier and more reliable. Just keep an extra set in my camera bag so when I hit the low battery warning I'm not caught off guard. And if I'm on the road and need a set they are available anywhere.
Gave a bucket full of rechargables and two chargers away. Glad to see them gone.

Not all rechargeables are created equal.

I would recommend Sanyo Eneloops or Uniross Hybrios. These are low self discharge NiMH. The normal NiMH self discharge too quickly.

To be effective, rechargable batteries must be used in conjunction with a good charger. With a MAHA conditioning charger and Rayovac Hybrids, I get over 1,000 shots on the Kx. A cheap charger will not fully charge batteries and can ruin them.

The battery of choice for my Km is Rayovac NiMH. However, I just purchased a new set of Duracell(Supposed Eneloop Rebadged) NiMH for my upcoming trip. I'll see how that goes. If not well I might take the plunge into Lithium Energizer. I found the Rayovac's don't last too long especially in lower temperatures. However, as mentioned earlier good charger is a must. I know 1h speed chargers won't cut it. Ran it once in an emergency and the camera just coughed the batteries out.

I say get Eneloops and be done with it. It is universally agreed to be the better ones.

Eneloops, or any of their rebranded versions if you want rechargeable. Energizer lithium ultimates if you want disposables. Eneloops yield 700 or so shots between charges for me - sometimes more, sometimes less depending on how often I chimp. The Energizers I got with the camera still showed green after 1500 or 1600 shots when I pulled them for the

Edit: make sure your firmware is up to date regardless of the batteries you choose!
