I was out the other night shooting two D7000s. I noticed one went to low battery with only a bar remaining, but didn't die on me that I recall. When I got home the camera wouldn't turn on though. I popped the battery in the charger and left it over night and this morning put the battery in the camera, but no life. I pulled out a second en-el 15 that was getting low and put that in the charger, and noticed that when I did the orange light on the charger slowly blinked, which is what I remember happening during a successful charge. By comparison, the non-functioning battery made the orange light on the charger rapidly blink. What does this mean? I couldn't find anything online by searching...please help!
Sounds like a bad one. Hopefully you bought it new and can get it replaced thru the warranty (if under a year)
Rapid blinking does indeed spell trouble, won't blame your charger because the other EN-EL15 works fine. GL
Stating the obvious here, but check and see if it falls within the recalled batch #'s
Nope not a recalled battery. It's just so strange because it was working fine and then I went to turn the camera on and nothing, and now it won't charge. Does it ruin the battery to run it all the way down until your camera dies on you? If that is the reason then it would be a ridiculous one, but I can't think of what else it would be besides bad luck.

well that, unfortunately, doesn't paint an accurate picture of the situation i'm afraid. the "average" lifespan of a battery is 2-3 years depending on its usage (runs and cycling and now how the previous owner actually "used" it?). when you had it working did you ever look at the battery info on your D7000 for its "condition"?

I didn't ever look at the condition, I didn't even realize that was a menu option. Both my D7Ks were bought with low mileage, but for all I know an owner could have put a battery in from a more used camera. I didn't realize the lifespans were so short....frustrating for a $60 battery to just stop working over night but maybe that is a risk of buying used gear
+1 and I rotate several into the mix. Other tips: 3 charge/discharge cycles before ready for rotation,
only charge when needed, run 'em down to ~20%. This really work perhaps. I have 5 EN-EL4a's
that my D3/D700/D2Xs share. They're over 4 yrs old and all register 1 or 2. So maybe the proper
care and feeding is the answer...or I'm just lucky.
On the EN-EL15 battery that came with my D800, there is a date code with year, month, day that it was made. See if your battery has this on it. If it does and it indicates it's 2-3 years old.... that will answer your question.
Hey Will, would you explain what you mean by "3 charge/discharge cycles before ready for rotation"?
Also a couple questions...
1) is it really bad for the battery to let it die in the camera by running it down to zero? (wouldn't intentionally but would still like to know)
2) Is it really that bad to top batteries off? If my batteries are at 75% after a shoot and then I am going for a week long fishing trip without power, I would usually top them all off before leaving to get max life....
Hey Ben, I'm looking at the battery now and unfortunately don't see anything about the date it was produced :/

The date codes must be a recent addition to the batteries.

perhaps. I have 5 EN-EL4a's
