"Battery Age" Sun 24-Feb-13 03:09 AM by four eighty sparky
When I got my D7000 two years ago, I noticed that the battery age indicator in the monitor had a scale of 1-4. I assumed this meant years. However, after two years of solid use, they're both (I purchased a second battery with the camera) still at 0.
Anyone have solid intel on the meaning of the numbers? (Other than what's on page 242 of the manual)
I have several EN-EL3e batteries that are over 6 years old that are still at 0. I have two EN-EL4's that are about 7 years old that are at 3 on the life scale and a few EN-EL4a's at 1 and 2 on the life scale. Obviously I use the EN-EL4(a)'s much more than the EN-EL3e's. When the battery gets to 4 it is time to start considering getting a replacement. Good Luck and Enjoy your nikons!
If Nikon counters work as apple counts battery cycles then this would be normal. Apple counts and what wears on a battery are complete charges from a completely discharged battery. My guess is that you probably do not run out of battery before charging. I know that I will make sure I charge the battery before the shoot though it might have 80% charge. I would not worry about this as my expierence is a new camera will come along with a new battery. I must admit though my original spare battery that I bought for D100 went to D200, to D700 and my nephew is still using the battery after all of these years.
Each increment indicates about 10% of battery capacity gone, permanently. There is a SBS chip on each pack that carefully measures everything going in or out of the battery, charging, discharging, everything, and tracks the capacity (the body doesn't have a method of determining capacity on the pack, the pack tells the body). It really just means you've taken good care of your batteries.
Interesting thread. I have a D80 (bought new), D200 (used), and a D7000 bought new in May 2013. I have a pool of 5 EN-EL3e cells that I use interchangeably with the D80/D200, and after dozens of charge cycles all still show "new" condition. But after less than 10 charges of the D7000's EN-EL15, the battery age meter has already clicked over to "1". Disappointing, to say the least.
I've had my D7000 since last Christmas. It's had fairly light use and I've never fully discharged the battery. A couple of months ago it suddenly jumped from 0 to 3. I haven't sent it back yet as I've been out of the country but have been in contact with the supplier and they've asked me to return it to them. Derek
