Toshiba 4330211605 CR2430 3V Lithium Coin Battery 4-Pack

The Toshiba CR2430 is a 3-volt lithium manganese-dioxide coin cell battery sold in a 4-pack on branded consumer packaging with a tear-strip opening. Each cell measures 24mm in diameter and 5.0mm in height, fitting devices specifically designed for the CR2430 form factor. With a 620mAh capacity, these batteries offer meaningfully more energy storage than smaller coin cells like the CR2032, translating to longer service life in devices such as watches, fitness trackers, key fobs, and compact healthcare monitors.

Toshiba engineers these cells to Japanese quality standards, and the ten-year shelf life means you can purchase the 4-pack and store unused batteries without worrying about them losing their charge before you need them. The lithium manganese-dioxide chemistry provides a stable 3.0-volt output throughout the discharge cycle, which is important for devices that are sensitive to voltage drop. For anyone maintaining several devices that use the CR2430 size, this 4-pack offers a convenient way to keep replacements on hand.
