Save your batteries

One drawback with some digital cameras is how quickly they go through batteries. When you want to make sure you don’t run out of juice while snapping important photos, though, there are steps you can take. The display on the back of the camera is a power hog, so the first thing to do is turn it off. Wait until you’re done shooting everything you’re likely to need, then you can view photos if you wish. Also, don’t delete photos (unless you’re out of memory and need to take more pictures). Deleting and other photo- management functions that make digital cameras so convenient are just the kinds of actions that drain batteries.

With some types of rechargeable batteries, you must run them until they are depleted before recharging. If you don’t do this at least once a month for nickel cadmium and nickel metal-hydride batteries, you likely will notice they don’t hold a charge for as long as they used to. Lithium ion batteries are not susceptible to this "memory effect." Finally, you should not mix different types of batteries or mix old with new. Doing so can shorten battery life or possibly damage the batteries.
