"They look like your regular camera batteries"
These lithium ion batteries have a high mAh capacity (long battery life). They look like your regular camera batteries, small and portable, and are ready to be stowed away in your purse or camera case. I really only use cameras on specific occasions since I take most of my pictures on my phone. However, when I'm on vacation to a particular scenic local or I'm overseas somewhere I'm not due to back to for a long time, I like to use an actual camera to take really nice high quality pictures. During these specific occasions I definitely find that one battery is definitely not enough to last an entire day outside. When you're out and about there is no reasonable way or time to charge a camera battery
