Single-use battery Varta 4120 D Alkaline

The Varta 4120 D Alkaline is a single-use D-size battery designed to supply steady 1.5 V power to a wide range of devices. It measures 61.5 mm in height and 34.2 mm in diameter and has a cylindrical form factor compatible with common D-size designations such as AM1, MN1300, LR20 and similar types. Supplied as a pack of two, this alkaline cell is intended for applications where long-lasting, reliable disposable power is required.

Advantages

This alkaline battery offers stable voltage output and consistent performance over its discharge cycle, suitable for devices with moderate to high current draw. The D-size cell provides higher capacity compared to smaller sizes, extending runtime for portable equipment. Its standardized dimensions and chemistry ensure compatibility with a broad range of household and professional devices. The packaged pair provides immediate replacement or spare power when needed.
