Welcome, Lou!
I've been using batteries sold by SterlingTek. They were recommended by other users of advanced Nikon CoolPix cameras. I've been using a pair for over a year along with the original Nikon battery which came with the camera. They have worked well and reliably, and cost quite a bit less than Nikon's proprietary batteries.
