V have used all types of battery for this camera... but v can't take more than 2 pictures,den it's showing batery low.

Use alkiline, or the type battery your camera asked for
Put them in correctly.

Please try fully charging it. If it still won't work, it's time for a new battery.

Alkaline batteries just don't have the power for more than a few pictures in today's power hungry digital cameras. Some batteries may also have reached their shelf life at the store, and though brand-new right out of the package may even have problems just powering startup of the camera. The one's that came with your camera are just to show you that the camera works, but as you've discovered, they'll only last for a few pictures. Digital cameras that use AA's for the most part should only be used with modern rechargeable batteries. If you read the camera's instruction manual concerning batteries, you should see the same recommendation.
Modern rechargeable batteries have over 5 times the power density of alkaline batteries (that's right, they last up to 5 times longer than an alkaline battery. And you can recharge them over and over!). Keep in mind rechargeable batteries will save you much money in the long run over alkalines, AND they'll last for at least 100 pictures per charge (and probably many many more). You'll be very pleased with their performance, and may be angry with yourself for not buying them sooner. When at the store, look on the package for a power rating of at least 2500 mah.

It happens because some alkaline batteries just don't have the initial surge of power output required to drive all the little motors, the display and so on.

You need lithium batteries, like the 8x Ultimate Lithium.
They are expensive initially, but on average are more economical than the cheaper stuff.

I've tested them on my Kodak Z712 IS, and any owner of this camera knows what I'm talking about.

The best -and cheapest- solution I found, is the rechargeable Li-Ion batteries.
I got 2 batteries and one charger. I'm using one battery, while the other one is charging.

Does your camera use AA batteries, and you don't use Li AA batteries? You can see why cameras show low power warning for fully charged batteries Try Li-ion batteries then

This is likely because:

1. You are using the wrong types of batteries (Alkaline, Ni-Cd or Ni-MH batteries are recommended for digital cameras) NOTE: don't mix different types.
2. The battery is out of charging cycles and won't retain charge. (Most rechargeable batteries can be charged only about 1000 times after which they won't hold charge)
3. The batteries aren't 'powerful' enough. (low quality rechargeable batteries with low capacity shouldn't be used on digital cameras, Always buy batteries specialized for cameras (from camera stores or studios))
4. The wrong battery type is selected in the camera's settings. (Most cameras let you select the type of battery you are using from it's settings. Browse through the settings and see if this is the problem)

Hope that fixed it. Good luck.

If you post a query here, you may find someone who has had similar issues and can offer assistance. https://www.pentaxforums.com/forums/131-visitors-center

Clean the battery holder with a pencil eraser, otherwise go for good brand rechargeable battery AA 2700 mAh try it.

I assume we're not discussing the Sony DSC-W55 since that doesn't use AAA batteries.
The battery life varies depending both on the camcorder and the type of batteries. In general, lithiums will last longer than alkalines, which will last longer than a single charge on NiMHs. On cameras that give you the option, you'll use less juice shutting off the display and using the viewfinder. Many manuals will give you estimates of battery life, but these are estimates only, the battery life also depends on how YOU use your camcorder.

I had the same prolem. OK, try this. Try to discharge the AA batteries in some use, flashlight or else,,,,then recharge them, full charge, install the batteriers ...they should work fine....
I read somewhere that canon is able free of charge to correct a shortcircuit that the camera is susceptible to develop in the installation of batteries......But I hope the advise will work...
Remove batteries when not in use.
