Panasonic DMW-BCJ13 Lithium-Ion Battery

Finally, a battery that matches the original perfectly—it charges in about an hour and holds power exactly as long as the one that came with the camera. No memory effect, no worrying about topping it off mid-shoot.

Works perfectly with no memory effect issues—I can top it off whenever I want without worrying about degrading the battery life. The small size is a bonus, fitting easily in my camera bag.

Finally, a battery for my camera that actually holds a charge when I need it. This one’s lightweight and I’ve been charging it at random times without noticing any memory effect issues.
