Button cell battery Voltcraft CR1632 3V 130mAh Lithium coin cell

Voltcraft CR1632 3V 130mAh Lithium coin cell is a compact primary battery designed to provide a stable 3‑volt supply for small electronic devices. The cell delivers a nominal capacity of 130mAh in a flat, coin-shaped package compatible with devices specified for CR1632 size. Its chemistry and construction offer long shelf life and consistent voltage under moderate discharge, making it suitable for low-drain applications where reliable, compact power is required.

Advantages

The lithium chemistry ensures low self-discharge and an extended storage life, keeping the battery ready for use after long periods in storage. The 3V nominal voltage provides stable performance across a wide range of temperatures, and the 130mAh capacity balances compact dimensions with usable runtime for low‑current devices. The standardized CR1632 form factor allows straightforward single-cell replacement in devices designed for this size.
