6-Pack J-Type Alkaline Batteries

This pack contains six Duracell J-type 4LR61 alkaline cells, each delivering 6 volts for devices that require this specific form factor. The batteries measure 9 mm by 49 mm by 36 mm and are suited for compatible electronics such as certain remote controls, security sensors and medical instruments.

Sustained low-drain reliability

Alkaline chemistry provides a steady voltage output during the long, continuous draws typical of always-on sensors and backup circuits rather than short high-current bursts. The six-cell pack allows staggered replacement so critical devices remain powered without interruption.
