PBlais Nikonian since 19th Jan 2014Mon 22-Dec-14 02:57 PMLithium ion batteries age. That is they will go bad because of time alone. Same goes for computer laptop batteries. For long term storage charging to about 80% is a good way to store them. Leaving them plugged in a charger is a bad idea.
I would charge it up and see how long it goes. I find my D7100 (same battery) can go a whole day shooting and hardly move.
These batteries don't suffer from "memory failure" like a NiCD battery will. You should be able to recharge it and get use from it but it will fade sooner than a new battery would.Visit my Nikonians gallery.

gpoole Nikonian since 13th Feb 2004Mon 22-Dec-14 04:28 PMI have EL-EN15 batteries over 2 years old and EN-EL14 batteries 6 years old. All still show as "new". I have spares and before a shoot I rotate a freshly charged battery into the camera and immediately recharge the one I removed. Possibly using the batteries and charging them frequently and never letting them stay low for very long has helped prolong their lives.
According to Nikon, a charging life of 4 indicates "that the battery has reached the end of its charging life and should be replaced." If a recharge doesn't improve the life value, I think you should follow Nikon's recommendation and get a new on. Note that you can get EN-EL15 batteries at Best Buy, you don't need to go to Nikon or a camera store to buy them.Gary in West Michigan, USA.

I may have found the answer. I was using the battery in a Vello grip. I found that the grip was defective a was continually draining the battery. This is a problem that Vello acknowledged. Even though the grip,was past warranty, they sent me a replacement grip. Thank you Vello for both acknowledging the problem and replacing the grip.
I suspect the problem with the battery was not the battery, but that the grip was constantly draining the battery dead. After replacing the grip, the batteries stopped draining and I’ve not had a battery bad.
However, since that time the Vello grip gave out. An internal gear in the locking mechanism was digging into the case plastic and clogged up, freezing the mechanism. I’ve replaced it with a used Nikon MB/D11 and had no grip problems since. However, i did discover that Pearson batteries in a Nikon grip don’t power up properly.

MEMcD Nikonian since 24th Dec 2007Thu 18-Jan-18 11:43 AMHi Bob,
Glad to hear you figured out the problem.
Third party batteries are always a wild card.
Some have had no problems, others have had nothing but problems.
I am among the latter group. I have given up on false economy of third party batteries.
Thanks for the follow up.Best Regards,
Marty
