Win a Pentax Limited Lens: Raffle Now Live!

Hi!

I've been using my K-x for some years now and it still performs great, though I've always been struggling with the batteries. When I'm using the Energizer lithium ion based battery type it lasts really good, but I prefer rechargeable batteries.

The batteries I have been using for some time now is: GP2700AAHC (link), but I can't get them to last very long. I have the latest firmware in the camera and I have also set the camera to NiMh.

With that said, I wonder what type of batteries you use and if you have any other tips/ideas on this topic?

Best regards,
Eddie

I've used Sanyo Eneloops for my K-x and they've worked great. Just got the latest version of the Eneloop, the XX, and it seems to be longer lasting.

Great! I've already located a shop that has these batteries. I'll definitely try those next time I order.

The secret to eneloops is the charger!!!
I use eneloops and duracell rechargeable batteries and charge them all in the eneloop charger I get excellent life out of all of them. Its because it charges each battery individually even when you put 4 AA's in it still charges them individually.

99% of the other chargers out there charge in pairs and that is a battery killer. Most chargers, charge batteries as a sum of the pairs batteries voltage so if battery-a charges slow or has a lower voltage going in, battery-b will over charge and it snowballs each time until battery-b is toast.
