Nikon EN-EL14 Rechargeable Li-ion Battery

The short answer: it's a battery and I'm happy with it.The long answer: The first time I tried the battery out in my d5100 it ran down VERY quickly. After about 100 shots and a couple of short videos it was on the red, with one bar left! I was worried that it was a dud battery or worse a fake (some 1-star reviewers have suggested that). So I performed a test ...I charged up the battery that came with the camera and setup a time-lapse photo (900 shots, RAW, with the standard on-screen review after each shot, but no flash, no vibration reduction, no autofocus). That battery took over 800 shots until it made it to 1 white bar. From what I've read that's about right, so I knew it wasn't the camera that was going wrong.Next, I charged up this battery and did the same test with a time-lapse photo (same settings). It performed just as well - 800 shots and down to 1 white bar.What I discovered was (being new to DSLRs) was that all that fancy stuff makes a BIG difference. If you turn off the auto-focus, the vibration reduction, the live-view (yes, I know it's nice for those of us coming from point-and-shoot cameras) you're battery will last a lot longer. Even saving in JPEG rather than RAW will save some energy.So the lesson here (and this goes out to those people who, like me, are new to DSLRs) is that it pays to read the manual and check your settings.If you really can't live without using live-view and all those other things, then you can always buy a battery grip that holds two batteries!

Good native Nikon batteries. Can't go wrong.

Original/official/genuine battery in the best price (from my search on google and eBay). I wanted a spare battery, and I was about to buy a pack of an unofficial charger and 2 unofficial batteries from eBay at about the same price as this one, but I didn't, and I think I won't regret it. As I found out from many reviews, some unofficial batteries doesn't work well or doesn't work at all (even if they say they do).It came fast enough, but the - envelope like - package was kinda small for the battery's box so it came a bit smashed, but ok. The battery was working, but it was almost empty so I charged it.

I read one or two reviews where buyers have experienced problems with this Battery but I needed one badly to back up the one that came with my new Nikon D5100SLR Camera. It arrived before time, was well packaged and the price was great. I charged it up fully and popped it in my camera. It worked perfectly straight away and I have had no troubles whatsoever. This battery is the real deal and cheaper than anything else I found. With the Spring time on the way, I plan to be out and about with the camera and I am seriously considering buying another battery. You can't have too much of a good thing. Have no fears, this battery works well and I can recommend it. 5*****

The main reason I bought this battery was because I wanted a spare battery for travelling. I had a 5 day trip to New York where I was going to be using my Nikon D3200 a lot of the time so I wanted to make sure my battery wouldn't die half way through the day taking photos. I must say I'm not disappointed! During my 5 day trip I only had to change my battery once. So from my experience they last for 2-4 days with heavy use throughout the day. It is such a relief to know you have a spare battery, and I definitely recommend getting the official Nikon brand, as in the past I've had issues with cheap versions that aren't the real deal. Yes it is rather expensive but you won't regret getting this! A spare battery is a just-have for any photography enthusiast.

For the price you can't argue with a genuine Nikon battery. I bought this as a back up after going to the zoo and not having a spare battery and my other ran out - d'oh! The service from the seller was great, product charges up and works in my Nikon D3100. The only reason I can't give this 5 stars is because other than charging and using it for 5 minutes I haven't really used the battery and also the box arrived bashed and appeared to have already been used before....otherwise, a good product at a decent price.

In the past, I have been content with buying my second battery from a third party manufacturer and paying mostly less than £20, as I am annoyed at the prices that companies charge for their own batteries. however, the last time i did this (for a Sony DSLR) the battery did not fit the camera or charger without adding a piece of card in for packing - so I ended up buying twice and having to get a proper battery anyway. So on this occasion, I was pleased that I was getting a proper Nikon battery for cheaper than most originals cost. the battery came boxed and the box had a stick NIKON hologram sticker on it to indicate an original product.The company that sent it (POPCORN) were prompt (arrived 2 days later) and sent 2 advisory e-mails re the order, so I would be happy to deal with them again. the battery behaves exactly the same as the one that came with the camera in relation to charge times and performance. I bought this for my D5100.Happy to recommend. My rating for 5 starts is based on the fact that I got an original battery for about £15 cheaper than I have experienced with other manufacturers.
