Getting the most from a camera battery
When it comes to taking photos with your brand new digital camera, it will shortly come down to how long the battery is going to last. Digital cameras have evolved over the last 10 years to include more software and hardware built right into them and that puts a lot of stress on the typically rechargeable battery. If you are going to be shooting HD video with your DSLR, the battery might not last quite as long as if you were just going to fire off jpegs all day long. Most newer DSLR cameras will come with one rechargeable battery and that might not have to be charged each day depending on your usage.
With that being said, there is another way that you can extend your shooting time. All you have to do is buy another battery, bringing your rechargeable battery total to two. That will allow you to have one charged at all times as long as you can remember to put it on the charger. What I did was actually add a third battery to the mix and over the last few years have never been in a situation when my battery was dead and I could not use my DSLR. Some things that you can do to reduce the amount of battery drain you can get with your DSLR includes lowering the brightness on your LCD screen and even turning off the auto focus on your lens.
Just a couple of ways that you can maximize your DSLR battery usage.
