Hey Guys. I was charging my D2 & wanted to see the percentage that was left. Basically wanted to know if it was at 80, 90, etc etc. I pushed the on button. Then I saw the battery meter was grey with a question mark in the middle of it. It didn't say 80, or 90 percent like I was expecting. Normally U would see a battery with the inside of it being green. Is this normal or a setting I need to fix?
