FirstPower EN-EL15 /EL15a/EL15b/EL15c Batteries 2-Pack and USB Dual Charger Compatible with Nikon Z6 Z7 D750 D850 D7000 D7100 D7200 D7500 D500 D600 D610 D780 D800 D800e D810 D810a Cameras

These work perfectly in my Nikon D7500! A great value for the package deal of two batteries and a charger. So far so good with battery life. Perfect fit in the camera

UPDATE: Full Disclosure-testing done using Nikon D780 "Hybrid" DSLR using Nikon OEM EN-EL15a, EN-EL15b, EN-EL15c and First Power EN-EL15 3rd party batteries. FirstPower reached out after my first review and 100% standing by their products, they sent a complete new package to replace 1 defective battery out of the 2 pack + charger I originally ordered (see original review below). Mind you, I did not ask for a replacement as I was satisfied with my 1 good battery at this price point. KUDOS FIRSTPOWER! So curious, I decided to grab a handful the ten EN-EL15 series batteries accumulated since buying a Nikon D750 in 2015 to compare against the FirstPower, replacement batteries over a few days of shooting and video recording events. My original & oldest EN-EL15's may be toast as they were good for probably an average of 1000 +/- 100 shots (also depends on if using a zoom lens and zooming in and out). My more recently accumulated EN-EL15b's & c's were good for 1900-2230 shots using prime lenses, no flash. I only tested one of the brand new, FirstPower EN-EL15's fully charged using their provided charger and to my surprise, I was able to click off 2193 shots using a prime lens and no flash! That's much better than the 75% of OEM battery shot count in my unscientific review below. This means that in my use, a brand new, fully charged FirstPower EN-EL15 lasted longer than my older, Nikon, OEM EN-EL15 and 15a's, and lasted as long as my OEM EN-EL15b's and c's. FYI; the earlier Nikon EN-EL15's are 1900mAh and the EN-EL15c's are 2280mAh. The FirstPower EN-EL15 is listed at 2300mAh. If I remember, I'll post another update after I've cycled the FirstPower replacement EN-EL15's through a few charge cycles to see if they last as long as when brand new. So my overall impressions are that 1) FirstPower fully backs their product and 2) a brand new, fully charged FirstPower EN-EL15 replacement battery lasts as long as my Nikon EN-EL15b and EN-EL15c batteries that are not brand new! Definitely satisfied, especially at this price point! ORIGINAL REVIEW: ("Budget Batteries, Budget Performance"), One of the two EN-EL15 batteries works fine and seems to hold a charge and last about 75% as long as Nikon OEM batteries; however the other unit failed after initial charge and use. It would not charge back up using the battery charger included not my Nikon battery charger. At least I still use the dual battery charger to charge up multiple, 3rd party batteries at once. I'll keep charging Nikon OEM batteries using the Nikon OEM charger. As an event shooter, I go through a ton of batteries covering a single event so always have 4 to 6 on hand!

Update: The company reached out and offered a replacement that was quickly sent out and worked like a charm. Chris went above and beyond to rectify the issue. I would recommend this product, it works great and the customer service was excellent. I'm not sure why the replacement was initially for far out, maybe it was an Amazon issue. The CH2 position didn't work right out of the box. Replacement was scheduled for December 2029. Seriously, 2029. Will return for refund.

OEM camera batteries are the best for long life, but they are so expensive. These are a good option for the price. I haven't had any issues with them arriving bad or going bad quickly like some. The included charger is nice, but it does take a while to fully charge the batteries. They don't last as long as OEM, but they're not bad. Overall, I recommend them if you aren't going to buy the name brand/OEM batteries.

Rechargeable Batteries keep the fun going and provide the power to capture photos to treasure. I use these Batteries for my Nikon camera equipment and they last. Being able to charge 2 Batteries at the same time is best because that will provide a day full of professional photography. You should have 2 to 4 charged Batteries in your camera bag and a way to store charged and spent cases in different pockets for the quick change. Events usually have a lot of activities to cover and you don't want to run out of power before the day is over. Air Show Photos can capture amazing shots and you never know if you will be seeing an aircraft for the last time, especially the WWII Planes.

Quick service, works as advertised. New, so time will tell if they last as long as the Nikon battery, but charger is better than the name brand.

Works great with my Nikon 3200 and such a great price for a two pack!

High capacity, they work with the Zf! Wish the charger had a better indicator for battery life but I can't complain. It does charge quite fast.
