Product information

Description

The Nitecore NL166 is a single rechargeable Lithium‑Ion cell with a nominal voltage of 3.7 V designed for devices that accept NC‑16340 (16340-format) batteries. Compact and lightweight, this 1-piece battery delivers stable power for compatible flashlights, small electronics and other devices that require a 3.7 V Li‑Ion 16340 cell. The cell is intended as a replacement or spare for equipment built around the NC‑16340 form factor.

Advantages

The NL166 uses Lithium‑Ion chemistry to provide consistent voltage output and repeatable recharge cycles. Supplied as one cell, it offers convenient portability for users who need a compact power source. The 3.7 V nominal voltage matches the specification for many 16340-compatible devices, enabling direct substitution where that format is supported. Its single-cell format makes it simple to install in compatible battery compartments and accessories.
