Alternating batteries this way will help you keep shooting even in frigid conditions.Nishi, Y. When the first battery gets low, move it inside your jacket to warm up and replace it with the fresh one. If shooting in cold conditions keep that spare battery inside your coat, close to your body to keep it warm.

Heat and cold are hard on batteries so try not to leave them in the car in summer or winter. Having the batteries labeled by date purchased makes it easier to keep track of them and offers a quick indication of age. That way when the battery in the camera gets low on power, you can swap it out for a fresh one. The best way to avoid charging your battery unnecessarily is to have at least two batteries. In either case, make sure to check with the instruction manual for complete details on how to read and access these important information screens. Most D-SLR cameras use the more traditional battery level icons located on the camera's LCD screen that indicates when the battery is fully charged, partially charged, low battery or exhausted. (Check your manual to see if your camera does so.) When you access the Menu/Shooting Menu/Battery Info, the LCD screen reveals the following information the battery meter shows the level of power remaining, the picture meter shows how many pictures have been taken, calibration lets you know when to calibrate the battery and battery age tells you when to get a new battery. Select Nikon D-SLRs use batteries that contain information communicated to the camera about the status of the battery being used. In other words, it's not necessary to fully discharge a lithium-ion battery before charging it, but to get the longest life from a battery, only charge it when needed. However, like any battery, they have a limited life, and that's based on how many times they're recharged. That helps determine when to recharge them.Īctually, it's safe to recharge them at any time, because lithium-ion batteries don't have a memory effect that reduces their capacity by charging too soon). They hold their charge longer and, more importantly, give better information on how much power they still have. They're great improvements over the rechargeable nickel-cadmium batteries we used to use. Most of today's digital cameras use rechargeable lithium-ion batteries. Few people want to spend much time thinking about the little, practical things like taking care of your batteries and memory cards-but, it's important.

When it comes to photography, we want to be right out there doing the fun stuff-making pictures and playing with light, composition, color and exposure.
