EN-EL15 EN-EL15A RAVPower 2040mAh Rechargeable Camera Battery and Charger Set for Nikon d750 d7200 d7100 d800 d850 d810 d610 d500 battery and More

I got these batteries and charger recently and used them in a Nikon D810 DSLR on a 5 day trip to Iceland. It was peak winters (~ -10 degrees Centigrade) in Iceland which meant batteries die fast, hence I bought this dual pack to be able to shoot with three batteries. I chose RavPower as I already have portable chargers, car chargers, charging cables etc from RAVPower and I am extremely happy with them.I am very happy with this product as I used them continuously for five days as my primary batteries and they didn't perform any lesser than the original Nikon battery. The charger is also very lightweight, can be charged with a USB cable (hence, takes less space), and fully charges the battery in less than four hours. I only had to charge once during the trip, so I highly recommend these. If they die in next few months, I will come back and change this review.

I've been looking for some replacement batteries for my Nikon D810, but at first sight of high insanely expensive Nikon genuine batteries are, I looked elsewhere. I've bought other third-party EN-EL15 batteries before but while they've worked, you get what you pay for and they're getting a little tired, so I thought I would try a different manufacturer.I found the EN-EL15A RAVPower 2100mAh Rechargeable pack from on Amazon and was initially a bit skeptical. Two high-capacity batteries at a good price point and a charger too? I was expecting that the batteries would offer capacity well below advertised and that the charger would be useless. How wrong I was, though.The kit was received in a well-presented box (it would make a nice present) and I loaded them into the charger and left them on my desk to charge. Within a fairly short timeframe (an hour or so?), both charge lights indicated that the batteries were fully charged. They come partially charged from the factory, so far so good.When I got home is when I found a problem with one of the batteries. I won't go into detail here, but what I will say is that Sunvalleytek-UK, the suppliers, sorted out the problem very quickly. Fantastic customer service.At this price point, the claimed 2100mAh offers exceptional value for money but, as I said, I've become a little skeptical about battery capacity claims. However, having charged up the batteries in the supplied charger I ran them through a discharge cycle on my iMAX B6 Mini Professional Discharger and was very pleasantly surprised. Both batteries actually exceeded their stated capacity by a few tens of mAh, something I've only ever seen in the more expensive Li-Ion batteries I've bought in the past.I also tested the charge capacity of the batteries when charged with the official Nikon charger. It would seem that while the RAVPower charger would appear to be a far less sophisticated charger then the Nikon (2-wire connector as opposed to the 5-wire connector in the Nikon charger) there was no significant difference in measured capacity.In summary, with the price of two batteries from RAVPower being a fraction of the cost of the official Nikon equivalent, and with the addition of a very serviceable charger in the kit too, the pack offers very good value for money. The batteries I received exceeded their stated capacity and the charger, being powered from a standard USB socket, offers a degree of flexibility that will also prove very useful. I can also vouch for the excellent customer service from the vendor too, who very quickly resolved the issue with the duff battery.In short, a great product at a great price from a good supplier. It doesn't get much better than that, and I’m happy to offer my unequivocal recommendation for this product, and the supplier, Sunvalleytek-UK.UPDATE 01/09/2019: I bought another pack of these batteries but was disappointed to find that the batteries are no longer rated at 2100mAh as advertised. They are now rated at 2040mAh. Having completed testing, I can confirm that both batteries exceeded the 2040mAh capacity as stated on the battery, but that's not what I thought I was buying!My previous 5-star rating has been reduced to a 4. If you're going to downgrade the items your selling, then the supplier should have the courtesy to change the advertisement/listings accordingly.

I had two batteries for my D810 - the original Nikon EN-EL15 battery, and a Duracell copy. And which do you think failed? The Nikon of course, proving once again that Nikon accessories aren't always the quality they're supposed to be. This RAVPower kit was the answer to my problem and has given me two great batteries and a double charger for less than the price of a single Nikon EN-EL15. Obviously, I can't comment on the longevity of the RAVPower batteries as they're new, but the quality seems excellent and I have every faith in them; the same goes for the charger.

I bought this 2 batteries and USB charger kit on sale as it was cheaper than buying an OEM battery for Nikon. I have a Nikon D7200 and this battery is fully compatible with my camera.What I like the most is the charger that uses Micro USB connection to charge. Nikon needs to learn from this as Nikon charger and main cable is too bulky. With USB charger I can use my mobile charger and in car USB charging facilities. I do not have to carry Nikon charger anymore.Yes USB charger is slow charging but like me if you have 4 batteries who cares. I put both new batteries in the charger and left it over night, they were fully charged in the morning. Some reviews mentioned that batteries were only showing 95% charge but this is not the case with my batteries. I tested both batteries in my D7200 camera and both shows 100% . Perhaps you need to leave the batteries on the charge for longer, like I did.It is too early to say anything about Longevity but as I read other reviews saying they had these batteries for over a year without any issues, I am confident they will be as good as OEM Nikon batteries. Ravpower is my trusted brand as I have bought many Ravpower products and they all are top notch.

Ordered to be used in the Nikon D7500. The batteries work fine in the camera and last well. Certainly a great cheaper alternative to the genuine Nikon battery. The charger is also much less bulky than the Nikon charger and charges the original Nikon cell just fine. The sellers customer service is also first class. I initially had a problem with one of the cells (it worked fine but didn't seem to stop charging when full). The seller responded very quickly offering a full refund or replacement. A replacement was with me in a couple of days so you can certainly buy with confidence.

There were some bad revues for this product, but I decided to chance it since it does come with two batteries and the whole thing is cheaper than one genuine Nikon battery. This is designed to work via a USB connector. i.e. it is not a mains charger unless you have an adaptor. Usefully, with the correct adaptor in a car, they can be charged whilst you are driving. This is a valuable asset if you are shooting out in the wilds. I have not had it long enough to check the life of the included batteries, but the camera battery test does indicate that they are fully charged. Also charges regular Nikon batteries. The red light turns green when fully charged. I don't think that this is a speedy charger. Treat it as a trickle charger.
