No.
Nikon D series lenses are interchangeable among Nikon digital SLR cameras.
I think that Nikon batteries are good and they help last long in my camera. Don't take my word for it, if I were you I would look up reviews on the internet.
Nikon batteries come in a variety of shapes and sizes. Each battery is different depending on the camera. Most Nikon batteries now are small square batteries that are rechargeable; they have a relatively good lifespan. Nikon batteries are made out of either Nickel Metal Hydride or Nickel Cadmium, depending on the battery. Both of these are rechargeable. When the battery does not hold a long charge between recharges, it is time for a new battery.
No. The cool pix series does not have interchangeable lenses.
The D Battery has more nikon in it
Yes. Nikon recommend their own EN-MH2 Ni-MH rechargeables.
No, you do not. If it takes regular batteries such as double a or triple a, you can use any brand. If the camera came with it's own rechargeable battery, you should use it. If it quits working, buy one just like it.
The type of battery that a Nikon Coolpix camera takes depends on the specific model. However, most Nikon models take the 3.7V 740mAh lithium ion battery.
There are many different Nikon cameras. The compact digital cameras from Nikon are mainly simple "shoot and point" cameras where you open the shutter, point the camera at what you want to take a picture of and press the shutter. Other Nikon cameras have an interchangeable lens and adjustable focus to improve picture quality.
It really isn't cheaper to buy batteries online unless you are talking about a specific battery for your model of camera. In that case, I would call your manufacturer, but if you are just looking for standard batteries, any home depot or Wal-Mart will suffice.
Nikon consumer cameras have proprietary batteries that are normally charged in the camera. Your camera manual should explain this. Some of the newest charge via a USB connection to a computer.
AI stands for Automatic Indexing. This was developed by Nikon in 1977 to allow for interchangeable lenses to mount with a single twist.
