1 Star A total waste of money!!!!!
I bought this battery in November, charged it and put it in my camera bag. A week later (early December) I went to use it, and it showed that the battery needed charging. Strange, I thought, and re-charged it. Same scenario. I never even got to use the thing. It is worthless.
1 Star Simply doesn’t work with my D90
Although it looks and feels not bad, it simply doesn’t work with my D90. So I’m returning it. A little disappointed because the Opteka D90 grip got very good review.
1 Star Would not work in D90
Nikon’s charger would show this battery as fully charged, but my D90 would show it as a dead battery. I have returned this battery and will be buying the OEM from Nikon. Don’t waste your time with this 3rd party battery, go for the OEM. I received this as a gift, and Amazon was amazing in helping me return this item for a refund.
1 Star Opteka EN-EL3E Won’t Work In New Nikon D90
Purchased the Opteka EN-EL3E for my new Nikon D90. Charged it in the Nikon charger and even though the charger shows it charged the D90 shows it is not so battery will not work in D90. Contacted 47st Photo with two emails asking to return for replacement and they do not answer. Save your money and your time and buy a genuine Nikon battery, at least their support people answer you!
1 Star Don’t waste your time
Save yourself some trouble and buy the real Nikon battery. The new EN-EL3e is an improved battery from it’s predecessor. I purchased this Opteka for my D90 and it DID NOT recognize it. If I were you I would not risk it. It was cheap enough for me to try, but not worth the money or RISK of you do try it on your Nikon and something goes wrong so I am returning it to Amazon. From now on, I play no games an only buy Nikon original stuff. Amazon has a very good price on the Nikon branded battery. You pay for what you get, in this case I got nothing though
