Duracell D377 single-use Silver‑Oxide button battery 1.5 V, 3 mm height, Ø 18 mm

Duracell D377 is a single‑use silver‑oxide button battery with a nominal voltage of 1.5 V and compact dimensions of 3 mm height and 18 mm diameter. Weighing approximately 5 g, this coin cell is designed to deliver stable voltage for low‑drain portable electronics. It is non-rechargeable and supplied as a single unit, suitable for devices where long shelf life and consistent output are required.

Advantages

The silver‑oxide chemistry ensures a stable discharge profile and reliable voltage over the battery's service life. Its small form factor and low weight allow use in compact devices without adding bulk. As a single‑use cell, it requires no charging and provides predictable performance for low‑power applications. Duracell manufacturing standards provide consistent quality and storage stability for spare or replacement batteries.
