Is a USB-C Nikon D750 battery worth it?

The Nikon D750 can use EN-EL15 and EN-EL15c batteries.
There is no way to charge the battery while it is in the camera. The battery cannot be charged via the USB port. It’s only for data transfer.
The Nikon MH-25 is the EN-EL15 battery charger. I would rather have a third party USB-C charger as a replacement.
Newer third party replacement batteries can have built-in USB-C charging. That removes the need to have a dedicated charger for the D750.
Even with that feature, two USB-C rechargeable batteries are cheaper than a Nikon battery.
I like third party batteries because of how much cheaper they are. From testing I’ve done, they have ~90% of the capacity of an OEM Nikon battery. I would expect one with USB-C charging to be ~85% because of the space taken up by electronics.
The only time I would recommend OEM Nikon batteries is for professional use.
Nikon D750 Battery
A Nikon EN-EL15 was originally sold with the D750. EN-EL15c batteries are still available from Nikon.
Older EN-EL15 batteries can also be used.
Nikon D750 batteries are still available for purchase. However, Nikon EN-EL15 batteries are expensive.
Two third party batteries will be cheaper than an official Nikon battery. It’s important to buy them from a Nikon dealer because there are lots of fakes out there.
Integrated USB-C charging is a newer feature that is in some third party batteries.

What’s the difference between EN-EL15 versions?
| Battery Model | Information | Capacity | Energy |
|---|---|---|---|

| EN-EL15b | Supported: Z 8, Z f, Z6III, Z 6II, Z 7II, Z 6, Z 7, Z 5, and D780 | 1900mAh | 14Wh |
| EN-EL15a | Use the MH-25 or MH-25a battery charger. | 1900mAh | 14Wh |
| EN-EL15 | Not supported on: Z 8, Z f, Z6III. | 1900mAh | 14Wh |
Nikon is only selling the EN-EL15c. Earlier version have been discontinued.

How long does a Nikon D750 battery last?
The Nikon D750 has a CIPA rating of 1230 shots with a battery. Using live view will reduce that.
Approximately 55 minutes of video can be recorded at 1080p60. (Nikon D750 manual - Battery Life)
As a battery goes through charge cycles, the maximum capacity will be reduced. In my experience, third party batteries degrade faster than Nikon camera batteries.
Nikon does not provide information on how many charge cycles EN-EL15 batteries are rated for. Generally lithium-ion batteries are good for 400-500 charge cycles.
Battery Grip
The Nikon MB-D16 is the official battery grip for the Nikon D750.
It increases the battery life of the camera. Controls are added for using the camera in portrait orientation.
How to Charge Battery
The USB port will not charge a battery in the Nikon D750. The USB port is only for data transfer.
A Nikon MH-25 battery charger needs to be used. Third party chargers can have USB-C charging.
There are newer third party batteries with built-in USB-C charging. I would expect the capacity to be 10% lower because of the room taken up by the USB-C port.
That doesn’t bother me because 2 or more third party batteries will be cheaper than a official Nikon battery.
Signs of Battery Failure
If a battery is draining quickly, it may be failing. This happens because lithium ion batteries slightly degrade with each charge cycle.
After hundreds of charge cycles, the reduction in capacity is noticeable.
If a battery is swollen or puffing out, that is a sign the battery is no good. Especially if it will not fit in the D750’s battery compartment.
Batteries should not spin on flat surfaces. It’s a bad sign if it spins like a top.
The final thing to look for is if the battery is hot to the touch during charging. That’s a sign of high internal resistance, which happens with old or damaged batteries.
Battery Disposal
Lithium ion batteries are a fire risk. That remains true for transportation and sanitation workers.
Many types contain heavy metals that can cause water pollution.
It’s important to dispose of them properly at a recycling facility or hazardous waste collection point.
