Question: how do I  know when battery can no longer be recharged?
Document: I ordered a new battery because the camera was not holding a charge longer than 2 days. It still is not holding the charge longer than 3-4 days.with the NEW  battery. The camera is 3 years old. NOT time for a new camera. I don't know if it is the camera OR the battery Thanks for asking
This battery is exactly what our camera had in it when it was first purcahsed in 2007. The battery worked perfectly and lasted for a long time before needing to be recharged. I would recommend anyone needing a new battery for their Nikon, purchase this one.
I think the battery worked fine and I would recommend this seller. Unfortunately, I dropped and busted my camera midway through the trip, so I have no idea how well this battery worked after being recharged and or being used for a long time.
Ordered replacement battery for my cool pix camera. I know it is just a battery, but wanted the manufacturers battery so that it worked just like the original battery.
I take a lot of photos with a lot of different cameras. I always try and have a spare battery because you never know when the original will quit. Great battery.
Did not last on a charge any longer than the original battery I had in the camera. Not in love with it.
Big disappointment, this new battery needed to be recharged before it could be used in my camera. Sure would have been helpful if this fact was mentioned in the product description.
For me it turned out to not be the battery. Yall might want to check your memory card -- and not listen to Nikon tech support that you need it serviced. lol  Hope this helps someone. I know how frustrated I was.
I charged the battery and after only two days with just a few photos taken it needed recharging. Should hold a charge much longer.
Very happy....battery is just the thing my camera needed! Had the old one for eight years, I hope that this one lasts as long or longer!
Answer: If it is charged, soon after you plug it in you will see the green light blink.  That is as much charge your going to get.   Charge it near you, keep eye on it.  When a battery is no good it might start to blink but you won't be able to turn it on.  After you have a full charge, run the battery all the way down, make sure it's real low, that way when you charge it up you train the battery for long life.
