Understanding My Nikon D40 Battery Needs

When I decided to invest in the Nikon D40, I quickly learned that having a reliable battery is crucial for capturing those perfect moments. The D40 typically uses the EN-EL9 lithium-ion battery, which I found to be lightweight and efficient. It’s important for me to have a good understanding of how this battery functions and its specifications.

Higher mAh ratings generally mean longer usage times, which is something I always strive for.
