Quick Answer

The Nikon EN-EL15b is a rechargeable lithium-ion battery that powers many popular Nikon DSLR and mirrorless cameras. It offers slightly more capacity than the older EN-EL15a and is fully compatible with most cameras that accept the EN-EL15 series.

Why the EN-EL15b Matters

The EN-EL15b is part of Nikon's EN-EL15 battery family, which has powered a wide range of cameras for years. It uses the same shape and connector as the EN-EL15 and EN-EL15a, so it fits in any camera that accepts those batteries. The main difference is a slightly higher capacity, which can give you a few extra shots per charge.

If you already own an EN-EL15 or EN-EL15a, the EN-EL15b is a drop-in replacement. It also works in battery grips that accept EN-EL15 series batteries, making it a versatile choice for photographers who shoot with multiple bodies.

Compatibility Check

Before buying, confirm that your camera lists EN-EL15b as a supported battery. While most EN-EL15 series cameras work fine, a few older models may only support the original EN-EL15 or EN-EL15a. Check your camera manual or Nikon's website for the official list.

The EN-EL15b is also the standard battery for many Nikon Z mirrorless cameras, so it's a common choice for hybrid shooters who use both DSLRs and mirrorless bodies.
