Nikon EN-EL15b Rechargeable Li-ion Battery for Compatible Nikon DSLR and Mirrorless Cameras (Genuine Nikon Accessory)

I ordered from Amazon vendor. Be careful which vendor you get your battery from. The one I received is exactly like the one I got with my Z6 and the second one I got from BHPhoto last year. The Amazon battery is legit.These batteries are fantastic in my Z6. I lost one of them during a hike in the Smokies, and I really need two for the types of trips I go on. One of these batteries gives fantastic battery life. I have gotten 3000 photos on a single charge while shooting BIF's on a couple occasions. Mixed photos and video, its more like 800-1000 photos and 30-40 mins of 4k video. Plenty for most excursions. Hopefully I wont lose another.After a year on the original and second battery I bought at camera purchase, I had no noticeable decline in battery life. These were as strong as they were on day 1. The only time I noticed a little decrease in performance was in cold weather. Im talking less than 32F. Even then the batteries still provided adequate battery life. The camera would start to have issues, but the batteries were still strong.These are expensive, but they are good batteries. I would buy again.

It maybe just the camera (Nikon d7500), but sometimes it just gobbles up a battery and have to change it out. Like in just one day. I going on my last DSLR which was a Nikon D50 (I know, they're not even in the same realm of capability) but the D50 would last a week or two on a battery. Like I said it maybe that just the camera need a lot more umph to run it. But it is an outstanding camera. Love the results. I am very happy with it.

It seems that battery life is improving. This battery lasts twice as long as the previous model. On my D800E cameras, it seems that I can pretty much photograph for over 6 hours or more with these new batteries. I have a habit of turning off my camera on a photo trip when I am not actually shooting to extend the battery life. I can actually shoot all day on this battery with that technique.I now use the older batteries as backup batteries and these batteries ( I purchased two ) stay in my cameras as the work horses. You will be pleasantly surprised when you upgrade to this newer model.

I originally thought this battery was defective as it seemed to drain just sitting in the camera but I must not have charged it fully as I have not had that issue again. So far, it lasts for as much as two to three full day outings for me (about 2-3 hours of use each day) before it needs charged. It is OEM and so it works as well as the battery that originally came with the D850 so I am pleased with it, especially for the price.

Ordered 2 batteries, one showed up. I contacted the company, they apologized and sent the second battery. Great customer service.

This is the "b" series Nikon EN-EL15b battery, and works with all Nikons using the earlier version EN-EL series batteries. Yes, it is expensive - perhaps way too expensive. However, it works extremely well and is very dependable, a must have if you use your cameras professionally. I have tried cheaper, 3rd party batteries in the past, while shooting thousands of photos during marathon races, and have had terrible luck with the cheaper, 3d party batteries, which fail way too often. The Nikon batteries, though expensive, are very dependable and will carry you through those rough, critical photo assignments.

Although it is possible to use EN-EL15 and EN-EL15a batteries in the new Nikon Z7 and forthcoming Z6 cameras, only the new 15b version is able to be charged while inside the camera. This is done by simply plugging in a 5 volt 3 amp USB C power adapter. The needed EH-7P power adapter is included with the Z7, but also works with similar adapters I have for a current Macbook Pro and a 2015 Google Pixel Chromebook. That allows me to support all three devices with only a single charger when traveling.The new EN-EL15b battery also has a slightly higher capacity (1900 mAh) than the EN-EL15 and EN-EL15a variants, which is useful with the higher electrical needs of the new Z series cameras. My understanding is that the EN-EL15b can also be used in any camera that fits the EN-EL15 or EN-EL15a.It takes about 2 hours and 35 minutes to recharge the EN-EL15b when completely discharged, officially giving enough power for 330 shots on a Z7, but based on early tests usually enough for an all-day shooting session. Even so, I feel safer with 2 extra batteries, and love that I can charge 2 at once - one in the camera and one in the MH-25a plug-in charger supplied with the Z7.Anyone buying a Z series Nikon camera should definitely also buy at least one extra EN-EL15b battery, to be sure of enough power for a long day of shooting.

Wanted backup batteries for my Nikon Z bodies. This purchase was a great price and value. EN-EL15b was the same price that I was finding the older EN-EL15a on Amazon and other sites. So I pulled the trigger and bought this. The EN-EL15b can be used to charge in body with the Nikon Z bodies. I usually use the chargers, but it is nice to have the option to charge in body, like through USB in the car and on travel.
