I have this battery in my Coolpix P500 , I have taken over 200 Shots in daylight with the battery, Even in night with the flasher, i have taken over 100 Photos. I need an extra battery to keep with me.
I have had excellent results from this battery- lasts as long as expected when shooting, holds charge well when not in use, no "memory" problems. I use this with my P5100 and my P100. Through the NY internet Photo stores have found OEM and aftermarket spare batteries for $20.00-$26.00. Even at MSRP it's a fair price. I like that the charger is external so I can use the cameras while recharging a spare.
