Key Features

• Replacement for EN-EL25: Works with Nikon Z 30, Z 50 and Z fc so photographers can use a direct replacement without camera errors.
• Fully decoded: The camera recognizes the battery properly, avoiding annoying low-battery warnings or compatibility messages.
• USB-C rapid charging: Built-in USB-C input with 5V/1.6A support lets the battery reach full charge in about 1.75 hours using common chargers or power banks.
• Clear charge indicator: Red shows charging and green shows fully charged so you can check status at a glance.
• True capacity: Rated 1250mAh and claimed to handle roughly 2.5 hours of video or about 400 stills on a Z 50, making it suitable for extended shoots.
• Safety protection: Top-tier Li-ion cells and a multi-layer protection system cover overcharge, overvoltage and overcurrent for safer field use.
