Agree with other reviewers that this battery depletes at a slower rate and lasts longer than the nikon battery. The type C cable plug is the best for emergency charging or simply field charging without a charging "box". It is recommended that you cycle the full charge to fully depleted three times to activate the "memory" of the battery to hold a larger charge, so it reads in two of the three battery manuals I have, so I do it. I have no issues with the lights, red charging and green charged, however long it takes, especially when building the memory where it may change in duration. These batteries are a money saver and are good quality, not cheap junk like some out there, and are fully compatible with my Z6III camera.

As a working photographer, I’ve trusted Nikon batteries for years—so I was cautious about trying something different. After running this SMALLRIG EN-EL15C for over a year, I can honestly say it outperforms my OEM batteries. Runtime is actually a little longer, and I’ve never once had a charging warning pop up on my cameras. It just works.The USB-C charging is the game-changer. I can top it off from my V-Pro battery, or plug it into solar USB pack when I’m off-grid. No wall outlet required.I bought a blue and orange one to keep track of one and 2. However the bright orange shell makes it easy to spot if it gets dropped in the field—a small but thoughtful detail that saves headaches on long shoots. If I need to replace (probably because I lost it) I'll get another orange. The build feels solid, and it hasn’t let me down in desert heat, dust, or long days of sports and real estate work.If you want more flexibility than OEM without sacrificing reliability, this battery earns its spot in the kit. It’s become my go-to for everyday and remote shoots alike.

Batteries work great.Usb-c charging is very convenient.I do take pride in accepting the Dumb Consumer award.Last night I took the batteries out of my bag, placed the covers on, and charged them over night.When I woke up the charge indicator was still red.Charged them for 2 more hours, still red.When the orange covers are installed on the battery, the green fully charge indicator will appear red through the orange plastic cover.Light colors - Orange - not fully charged. Green - fully charged.Picture 1:Both are fully charged. The on on the left appears to be not charged but the orange covers makes the green light appear orange.Picture 2:Both batteries are fully charged but looking from an angle the green light on the battery closets appears more orange.Picture 3: All three batteries fully charged but the gray battery (another brand) fully charged indicator is a much brighter green even at an angle.I like both batteries. The orange of the Small Rig batteries are easier to find in any color bag interview, except orange.I would and have recommend this battery.(Apologize the pictures were cropped a bit)

Very comfortable but Nikon battery has more energy, DSLR IS OK but mirroless camera faster discharges the batteries than original battery. Pretty good color

I like this great idea... not hard to charge, and it gets a great, long lasting charge each and every time I require it. I am confident that this will serve me well.

These are my aftermarket batteries to go for. These work great and fit with my Nikon bodies from Z6III to Z8 without any issues. Easy to charge them via a USB-C port or with a battery charger. They are compatible with my Nikon cameras without getting any error messages. Batteries seem to last long without any issues. I think these are great for the money.

Camera: Nikon z7iiThis is the worst battery I have ever used in 8 years of photography. I was on a 10 week backpacking trip to Asia and Korea was my first stop, they made me throw out batteries due to flying restrictions and threw away 2 good batteries to keep this one and the battery broke the first time I used it. My camera just shot off and I thought I broke it as this battery was freshly charged. It now wont even charge on my charger and through USBC charger it charges but doesnt work.. It just simply doesnt work, I thought I broke my camera. I am pissed this battery sucks, I sent the company an Email hopefully it was a dud. I will change review if new battery works!

I’ve been using the SmallRig EN-EL15c battery with my Nikon Z8 and Z6III, and it’s proven to be a dependable power source. The increased capacity of 2400mAh over the original 2280mAh provides a noticeable extension in shooting time, which is beneficial during long sessions.The built-in USB-C charging port is a standout feature. It allows for direct charging without the need for a separate charger, making it convenient when traveling or shooting on location. Charging the battery to full capacity takes approximately 2.5 hours, which is efficient for my workflow.
