One of the most frustrating things about using a digital camera is that it always seems to run out of battery power at the worst times. What is the best way to pull a little more power out of your battery? You may have a few different solutions.

  1. Replace your old batteries. Remember that rechargeable batteries tend to lose their abilities to hold a full charge over time. As the batteries age, they have slightly diminished capacities — they hold less and less power. If your battery is a few years old, you might need to replace it because of this problem.

  2. Check for corrosion. Corrosion can be a common problem if you store a battery inside a camera for several weeks without using it, especially in a humid environment. A battery that has corrosion on it will have green or brown smudges on the metal connectors on the battery. Remove the buildup or the battery might not charge properly.

    Make sure there are no deep scratches or other smudges on the metal contacts on the battery or the metal contacts inside the battery compartment. Anything that interferes with the ability of the metal contacts to make a close connection may cause below-average battery performance on the camera.

  3. Reduce battery-draining activity. Beyond physical problems with the battery that could be causing it to perform below standards, you can take a few steps to reduce your camera's power usage in the short term.

    For example, if your camera has a viewfinder, use it to frame photos and turn off the LCD (which causes a significant power drain). You also can turn down the brightness of the screen to preserve battery power. Turn on the camera's battery-saving mode, which powers down the camera after a period of inactivity. Don't use the zoom lens unless you actually need it. Avoid using the flash unless you need it. Try to avoid scrolling through stored photos or cycling through the camera's menus as well.

  4. Only use your camera under ideal conditions. Using the camera in really cold weather can cause a battery to perform below its projected lifespan. If the camera is stored in a cold location, the battery won't hold its full charge, either. If you must work in cold conditions with your camera, try carrying the battery in a pocket close to your body, where the heat from your body will allow the battery to stay a little warmer than it would inside the camera, which will allow it to maintain its full charge for a longer amount of time versus keeping it inside a cold camera for an extended period of time.

  5. Pick up an extra battery. Carrying extra batteries is the best way to ensure you have enough power for your project. Because most digital cameras contain rechargeable batteries that specifically will only fit inside one particular model of camera, you cannot easily swap one battery from a different camera into your current camera, so you have to purchase a second rechargeable battery.
