Yesterday I was photographing a freinds wedding when my Nikon EN-EL3e batteries deciced to give up on me. I had two, one in my D300 and one in a Nikon battery grip, and both had been fully charged the day before.
All was going well and batteries showing as being 'full' in the display when suddenly I had a battery empty symbol and the camera shut down. I couldn't have happened at a worse time!!!
Luckily I had another camera so carried on with that. But when I turned the D300 back on a while later the dispay showed batteries fully charged, but within seconds had shuit down again. This happened a few times more.
Later in the day, it was fine, and working normally with no issues.
I have no idea what this was about and am really confused by it.
Has anyone any ideas or experienced anything similar??
