K&F Concept EN-EL15C Battery with 2600mAh Capacity and Type-C Fast Charging for for Nikon Z8, Z7II, Z 7, Z 6II, Z 6, Z5, D850, D810, D810A, D780, D750, D610, D500, D7500, D7200 Camera

There are slight differences between Nikon battery with K&F battery. Operational wise the battery works on Nikon Z6III body, I can charge the battery using the Z6 III body or directly usb C charge on the battery. Capacity wise I don’t see difference of number of shots between Nikon and this battery.

It's been common advice to only go with OEM when it comes to batteries for cameras. I think that used to be true, but isn't anymore. Battery technology has come so incredibly far, and third-party manufacturers are the ones leading the charge. Nowadays, third party is better, cheaper, and include all the best features too.

In terms of build-quality, this thing is top notch. The plastic feels solid, with no flex whatsoever. It slides into my Nikon Z7 with zero issues, and powers my camera just fine. The 2600 mAh capacity is 14% higher than OEM's 2280mAh capacity. It's also $26 cheaper than OEM too, at the time of writing. Most importantly however, it has that all powerful USB-C port built in, so you don't have to use an annoying wall outlet or dock to charge it. It's just so much more convenient charging it this way, and I would honestly pay more for this feature... but they charge less. The only thing I can't attest to yet is its longevity, but I'll be sure to update my review if anything changes with that. As it stands, this is a must-have for photographers that need extra juice for their cameras.

I would really like Nikon to come out with a charger that just goes around the end of the batter and plugs into USB, that way I would not have to carry their bulky charger with me. Until the day comes, this battery is a very good viable alternative. I don't have to carry around the anger and since I am already carrying USB chargers for the myself and the family, this is a no brainer.
The battery works great in my Camera. Not sure how many shots I get on a charge, will be comparing that over the next couple months and will update this when I do.

This battery has been a fantastic backup for my Nikon. The fast charging via USB-C has been a lifesaver during shoots when I need a quick recharge. I’ve noticed a significant improvement in capacity over the standard battery, which has extended my shooting sessions without needing to swap batteries as often. The compatibility with various Nikon models makes it versatile, and I appreciate the safety features that prevent overcharging and overheating. It’s become an essential part of my gear, especially for long, on-location shoots.

This type of battery is probably one of my favorite newer camera accessory tech that came out in the last few years. Now that a lot of cameras don't come with a separate battery charger, since they can change in-camera, these are a perfect way to charge a spare at the same time be it at home through a dedicated charger or computer, or on the go with a laptop or power bank. They of course still charge in a dedicated battery charger.

Now back to this specific K&F version. It charges at around 10W so its among the faster charging batteries of this type. The cheaper alternatives charge at 5W speeds, so takes significantly longer to top off. It is also the nicest looking battery in my opinion; the brown and the blue ones are more eye catching for better or for worse but these look great. Honestly I don't really care about the color too much but manufacturers like to flex it as a selling point so... And finally, although it doesn't quite last as long as the original batteries these do manage to last a more than adequate amount of time. Knowing it is from K&F you also do get the peace of mind of a quality battery, unlike some of the weird, random branded traditionally charging third party batteries that are super inexpensive.

Now for my one complaint with this battery, it would be the location of the charging port. Most of the other USB-C charging batteries for other camera brands have the charging port at one of the extremities, usually on the opposite end of the actual pins of the battery. This one is on the effectively bottom side of the battery. It still works but I feel it is slightly less convenient sometimes... this is purely a matter of preference though, and considering SmallRig's version also charges at the same location this might be a limitation to the internal structure of the EN-EL15C.

Overall, this is an excellent choice for USB-C rechargeable batteries for your Nikon.

Been using this battery on my D500 and I've been happy with it. Due to our current heatwave (40+ days of over 110 degrees) I haven't been able to do an extended shoot so I don't on now how it compares to the original battery (will update in about two months). I also like that the battery has a built in USB type c plug for charging on the go. My one concern is the price. The battery cost $40 which seems a bit steep. Yes it's a lot cheaper the the original battery, but there's also other reliable brands that sell this type of battery for about $15 less.

Overall it seems to be a good product but a tad pricey.

The battery has a high capacity of 2600mAh, which provides a long-lasting charge, perfect for my extended photography sessions and video shoots. I never have to worry about running out of power during important moments.

The USB Type-C charging port is incredibly convenient—it charges fully in just 2.5 hours. The charging indicator is very helpful; the red light shows it's charging, and it turns green when fully charged. It makes it easy to know when the battery is ready to go.

I also love the multiple charging options. I can charge it using a power bank, car charger, or even Nikon's original chargers, making it versatile for both home and travel. The built-in protection system gives me peace of mind against overcharging, overheating, and short circuits.
