The Nikon MH-25A battery charger is a dedicated charger designed for compatible Nikon rechargeable camera batteries. It is particularly associated with the Nikon EN-EL15-series battery family, making it an important accessory for photographers who need a reliable way to recharge their camera batteries.
If you are searching for a Nikon MH-25A charger, you may want to know which batteries it supports, how long charging takes, how to use it correctly, and how the MH-25A compares with other Nikon battery chargers.
This guide covers the key information you need before buying, replacing, or using a Nikon MH-25A battery charger.
What Is the Nikon MH-25A Battery Charger?
The Nikon MH-25A battery charger is a wall-powered charger intended for compatible Nikon lithium-ion camera batteries.
It is designed to provide a dedicated charging solution rather than requiring the camera itself to remain connected to a power source.
The charger is commonly associated with Nikon’s EN-EL15 battery family, which has been used with numerous Nikon DSLR and mirrorless cameras.
Depending on the specific battery generation and camera, compatibility should always be verified before charging.
What Battery Does the Nikon MH-25A Charge?
The MH-25A is designed for compatible Nikon EN-EL15-series rechargeable lithium-ion batteries.
However, the EN-EL15 family has gone through several generations, so it is important not to assume that every battery carrying the EN-EL15 name has identical charging requirements.
Before using an MH-25A, check:
- The exact battery model
- Your Nikon camera model
- Nikon’s compatibility information
- The markings on the charger
- The battery manufacturer’s instructions
This is especially important when using third-party replacement batteries.
Nikon EN-EL15 Battery Compatibility
The EN-EL15 family includes multiple versions, which may have different features and compatibility characteristics.
You may encounter batteries labeled:
- EN-EL15
- EN-EL15a
- EN-EL15b
- EN-EL15c
- EN-EL15d
Although these batteries share a common family designation, charging compatibility can vary depending on the battery and charger.
If you are specifically purchasing a Nikon MH-25A battery charger, verify compatibility with your exact EN-EL15-series battery rather than relying only on the battery’s general name.
Which Nikon Cameras Use EN-EL15 Batteries?
The EN-EL15 family has been used across a broad range of Nikon cameras.
Compatible cameras can include selected models from Nikon’s:
- D7000 series
- D7100 series
- D7200 series
- D7500 series
- D800 series
- D810 series
- D850
- Z5 series
- Z6 series

- Other compatible Nikon models
However, compatibility can depend on the exact battery generation, camera firmware, and charging method.
Always check the documentation for your specific camera.

Step 4: Monitor the Charging Indicator
The charger’s indicator can provide information about the charging status.
The exact indicator behavior depends on the charger and battery.
Step 5: Remove the Battery
Once charging is complete, disconnect the charger from power and remove the battery if it is no longer needed.
Avoid leaving batteries charging unnecessarily for extended periods.
How Long Does the Nikon MH-25A Take to Charge?
Charging time depends on several factors, including:
- Battery capacity
- Remaining battery level
- Battery age
- Temperature
- Battery condition
- Power source
A partially discharged battery will generally require less time than a completely depleted battery.
For an accurate charging time, check the documentation supplied with your specific Nikon battery and charger.
How Do You Know When the Battery Is Fully Charged?
The Nikon MH-25A charger uses an indicator to show charging status.
The indicator changes according to the battery’s charging condition.
Because indicator behavior can vary between charger versions and documentation, consult the markings and instructions supplied with your particular MH-25A.
Does the Nikon MH-25A Charge EN-EL15a?
The MH-25A is associated with charging compatible EN-EL15-series batteries, including certain versions such as the EN-EL15a.
However, compatibility should be confirmed for the exact battery and camera combination.
If you own an EN-EL15a and are considering buying an MH-25A replacement charger, check the official Nikon compatibility information before purchase.
Does the Nikon MH-25A Charge EN-EL15b?
The EN-EL15b is another member of the EN-EL15 family.
Some Nikon cameras can also charge compatible EN-EL15b batteries through USB-based charging methods, while a dedicated battery charger may provide a convenient alternative.
Check the specifications of your particular battery and camera before using a charger.
Does the Nikon MH-25A Charge EN-EL15c?
The EN-EL15c is a later battery generation used with compatible Nikon cameras.
Because battery generations can have different charging features, users should verify the specific charger and battery combination rather than assuming that every EN-EL15-series battery is interchangeable in every charging situation.
Nikon MH-25A vs MH-25
The Nikon MH-25A and MH-25 are closely related Nikon battery chargers designed around compatible EN-EL15-series batteries.
When choosing between them, pay attention to:

It is designed to connect to an external power source and charge a compatible removable camera battery.
This makes it different from newer charging systems where the camera or battery can be connected directly through USB.
Can You Charge the Battery Inside a Nikon Camera?
Some newer Nikon cameras support USB charging or USB power delivery with compatible batteries and power sources.
Whether this is possible depends on the specific Nikon camera and battery.
Using a dedicated Nikon MH-25A battery charger has the advantage of allowing you to remove the battery from the camera and charge it separately.
This can be particularly convenient when you have multiple batteries.

Charge a Spare Battery
You can charge one battery while another remains in the camera or is being used.
Keep Multiple Batteries Ready
Photographers can maintain several charged batteries for long shoots.
Convenient Battery Management
A removable battery charger provides a dedicated charging station rather than tying up the camera.
Useful for Travel
A compact dedicated charger can be easier to organize with camera accessories when traveling.
