Wasabi Power Battery Grip Replacement for Nikon MB-D18 - Extra Battery

In this review of the Wasabi Power replacement MB-D18 battery grip, the bottom line is simple: photographers who use a Nikon D850 and want extended run time and improved handling for vertical shooting will find clear value here. The reviewer found it to be a practical, well-built grip that accepts multiple battery types and noticeably improves stability when shooting portrait orientation; it is especially useful for long events or wildlife shoots where changing batteries mid-session is disruptive. It is a direct replacement that keeps the camera balanced and ready for extended use.

Key Features

• Multi-battery compatibility: Accepts EN-EL15 / EN-EL15a batteries or AA cells so users can choose convenience or higher capacity options.
• Includes chamber covers: Ships with the EN-EL15/EN-EL15a chamber cover and an AA battery chamber cover to simplify switching battery types in the field.
• Optional high-speed option: Can accept EN-EL18 series batteries with an optional BL-5 chamber cover to achieve faster continuous shooting when required.
• Improved handling: Adds a substantial vertical grip for increased stability and control during portrait-orientation shooting and heavy-lens use.
• Battery life boost: Allows multiple batteries to be installed to extend shooting time for events, travel, or long sessions without frequent swaps.
• Warranty included: Backed by a 3-year manufacturer warranty for added confidence in long-term use.

Who It's For

This battery grip is aimed at Nikon D850 owners who routinely shoot long sessions, event photographers who need reliable extended battery life, and wildlife or sports shooters who benefit from improved vertical handling and the option of higher continuous frames per second using EN-EL18 series cells. It also appeals to users who like the flexibility of using AA cells in a pinch.

Photographers who rarely shoot vertical orientation, do not need extended battery capacity, or prefer to keep gear minimal may not need a grip. Also, those who require the EN-EL18 high-speed setup should note the BL-5 chamber cover is sold separately.
