How To Extend The Battery Life On Your DSLR Camera

Photography enthusiasts the world over love their DSLR cameras, but as with all things in the modern world they come with one major consideration: how can you keep them powered up for as long as possible while you're out and about? Spare camera batteries can be expensive, and they won't always fit inside your camera bag. Thankfully, there are a few things you can do to help your camera keep running for as long as possible.

Keep your batteries at a comfortable temperature.

If you're travelling somewhere with extremes of temperature--either hot or cold--take steps to ensure that your camera and its batteries will be well-insulated. Neither extreme is good for them and can reduce their lifespan as well as potentially causing them to drain power more quickly than is ideal.

Use the manual viewfinder wherever possible.

The LCD screen is great, but it's also the single biggest drain on a DSLR's battery life. For many shots you can do just as good a job of lining it all up using your camera's manual viewfinder, so practice going without from time to time.

Make sure you switch off features you're not using.

When you've mounted your camera to a tripod, switch off Image Stabilisation. When you're not uploading photos, turn off your camera's WiFi capabilities. Switch off image previews after every shot; they're a bigger drain than you might imagine. Keep your LCD screen brightness as low as possible, and remember that auto-adjusting brightness settings can use more power than adjusting the brightness manually.

Invest in a detachable flash rather than using the built-in one.

Stand-alone flashes generally have their own power source, and that power source doesn't need to do anything but power the flash. Investing in one of these means your camera's main battery will never need to run a power-hungry light again!

Minimise your use of zoom--move as much as you can!

You should really only use zoom when you can't possibly get any closer to your subject. Getting out of the habit of relying on your camera's zoom functions so that you don't have to move will result in higher-quality photographs as well as a longer battery life.

Learn how to focus manually for a double whammy of results.

Autofocus can be a great help to beginners, but it's a huge battery drain, and the results it produces are nothing like as good as those you can get from manual focus. Let your focus help frame your picture by indulging your creativity, rather than relying on a machine to do it for you.
