Likely, the first camera gear you think of might includes lenses, a camera bag, maybe a tripod. All of these are great, but if you run out of power, they won’t do you any good at all. So, one piece of camera gear you’ll definitely be happy to have when you’re out and about taking photos is a replacement battery.
Having a fully charged spare camera battery can save the day. If you’re shooting video or using your camera in cold conditions, you will go through your battery life more quickly than you realize, and the last thing you want is to miss those beautiful end-of-day shots you were planning to take.
Each DSLR, point-and-shoot and mirrorless camera requires a specific shape and style of battery, so prioritize compatibility when shopping. Many camera batteries are lithium-ion batteries—keep in mind that you cannot put lithium batteries in checked luggage on a plane.
