How long does a digital camera battery last? The general rule is that the batteries will degrade even if you have not used the camera for three years or if you have a premiere Sony digital camera, which is made with high quality. Knowing the average life of your digital camera batteries/battery pack beforehand will help you plan to replace the digital camera batteries on time with a spare battery. In general, the battery life depends on how your digital camera is made, the amount of time you leave the camera ON, how regular you use the camera, or how many still shots the camera can take in a second (burst mode). Additionally, turning ON and OFF the camera sucks power from the batteries.
Whenever you have a low battery and swap it with replacement batteries, the first photograph you take should be the exact image you took with the old battery. What if you have one battery? Well, the first photograph you take after the rechargeable batteries are full should be with the battery charger connected. But it would help if you considered getting a second Li-Ion battery if the first one gets low on charge. In addition to getting backup batteries, knowing how long your digital camera will last can also give you perspective on how many batteries you’ll require.
Next, when you get home and export your images to your computer, upload the photos you took with the old batteries and use a consistent tag. That way, you can search the tag of the battery and see the shot numbers. You will then be able to determine the average life of the type of battery in use.
The general rule is that the batteries will degrade even if you have not used the camera for three years.
