I am not using rechargeable batteries in mine. So far the battery life seems to be good. I do keep my camera turned off when not in use. I've had the camera about 2 mos. now, have taken quite a few pictures and still on the first set of batteries. Note: with the 26x optical and 26x digital on top of that this camera takes great moon shots. Looks like they were taken through a telescope. Craters are in sharp detail.
It does not use a charger. It uses 4 alkaline batteries - it doesn't like lithium batteries. But it lasts a good amount of time with 4 batteries. If you don't use video you can take hundreds of pics on those four. But using the video eats up the batteries very quickly.
I agree with the preceding comments that normal alkaline batteries last for seemingly a long time: I would estimate 200+ pictures and ~10 videos over a 2 month period (only 1 set so far). However, I was surprised when they finally did run out because the battery icon remained at "full", so I would recommend being prepared with replacements. As CBM notes, the standard AA size is much more convenient than custom batteries.
I have not had a problem with the batteries. My use of the camera is occasional so I am not taxing the batteries to any extent. I don't recall just how long I have had the camera, but to date I have had no need to change the batteries. To my knowledge this camera does not accept charging.
For Juli, I just bought 2 sets of rechargeable batteries (Bunny Batteries) with chargers and keep them charged up. If you don't want to go the rechargeable route, buy a 16 or 24 pk of AAs and ALWAYS keep an extra set of 4 in your camera bag. That way, if your camera runs out of power, you can pop another set in. My experience is, they last pretty well.
I found that the batteries that came with the camera did not last as long as I thought they would but they were not the best brand. I now have Duracell in the camera. Vidoes will lower the life of the batteries, I have taken hundreds of pics and this set of batteries seem just fine.
Camera does not have a charger.
Regardless, I am very happy with the camera and will recommend it to everyone.
As "Traditional Battery" cameras go, this one is much better than most. I've taken a weekend camping trip worth of photos on one set of batteries. I believe that you can buy some rechargeable batteries from the manufacturer and charge them inside the camera, but you may want to check with Nikon about that. I love this camera as a point-and-shoot. Makes a great back-up, but I do have to do some major "blue-shift" corrections in photoshop.
This camera takes 4 AA batteries. Surprisingly, they last a long time. I used it several times, several days a week, and it was at least 2 weeks before i had to change them. I love this camera! It takes amazing close ups & stills. Not great for sports or action bc the pics are blurry. ;0)
The camera doesn't need to be charged, but I'm cautious about having batteries handy when in use. So far I haven't had any problem with batteries going dead quickly, but I'm sure that depends on how often you use it and if you use videos, etc. I believe you can purchase rechargeable batteries, but I haven't done that. Hope this helps!
