Why do not my energizer EN-EL3e work on my Nikon D90?
I bought an Energizer EN-EL3e because it was cheaper than the Nikon one (by a margin enough). "I can charge up a couple of times (apparently it takes more of a cycle to start the celebration of a charge) and tested in the chamber did not work as the battery indicator not only shows the power. I took that battery back to the store and replaced it. I experienced the same thing with it. Any ideas?
I can not understand why anyone would want to spend much money on a camera and then want to buy a cheap battery that may or may not work. When I bought my camera, the salesperson told me to buy a battery always has my camera company for my camera. She said using any other type could ruin my camera. I decided at that time never take a chance with a cheap battery. I suggest you consider the battery again and this time get the Nikon. And if one does not work, call 800-Nikon-UX Nikon and see if they have an answer.
