#1. "RE: Nikon EN-EL14 Battery" In response to In response to 0 Sat 10-Nov-12 10:46 PM by DaveWooster
I would first check where your current Nikon battery was made and its "capacity" rating in milli Ampere Hours (or mAHr for short). If it was made in China, you probably can do better looking for one made in Japan (but you will pay more for it). Also, ask the capacity rating of any replacement prospect you find, and compare it to your Nikon's. And any spare is probably better than none, especially if you do not have a battery tester, or digital voltage meter (usually called a multimeter) to monitor your battery's condition. (The camera itself should help you monitor that.)
I see the country you're located in is the USA. I think the Promaster brand replacement for your Nikon is made in China, but the its price may be attractive if your dealer sells below suggested retail price. (Mine does.)
Finally, others here will have to please help with your specific Nikon camera's/battery's details.
