Rechargeable Batteries for K2000

I am a very green person and the thought of buying batteries over and over again and the environment impact is very upsetting.

My Nikon has a battery that I just put in the charger.

But my new Pentax K2000 uses batteries. Can I use rechargeable batteries and if so can I use cells ranging from 1500 to 2700mAh?

I read on the internet that the higher the capacity - the longer the run time.

As a practical matter, you have to use slow-self-discharge or "hybrid" AA batteries, such as Eneloop or Rayovac Hybrid. Capacity is not particularly important - most of these batteries have similar capacity.

All the Pentax dSLRs using AA batteries work well with the low self discharge (LSD) batteries like Eneloops.

Have a read of this thread - it covers most of what you need to know including other NiMH batteries etc.

I use the Eneloops in my K200D, the flash and the battery grip with no problems at all. Capacity is not an issue as they are all similar (about 2000mAh) - its their discharge curve thats important. The LSD batteries discharge curve is what gives them a long run time

Hope that helps......

Same here. I had a very difficult time with Energizer Rechargables on my k2000 before I switched to Eneloops. I even sent in my camera for warranty service, but they found nothing wrong, so I just stick to Lithium or Eneloops.
