Single-use battery Varta CR 2032 Nickel-Oxyhydroxide NiOx

The Varta CR 2032 Nickel-Oxyhydroxide (NiOx) single-use battery delivers 3 V in a compact 20 mm × 3.2 mm coin cell format. It is designed for reliable, long shelf-life power in small electronic devices and uses NiOx chemistry to provide higher energy density and stable voltage compared with standard lithium-manganese dioxide coin cells.

Advantages

High energy density and high capacity provide extended runtime for compatible devices. Excellent leakage resistance and extremely low self-discharge ensure long shelf life and safe storage. Low internal resistance (Ri) supports consistent power delivery, and available versions include cells with laser-welded terminal tabs for secure connections. The battery operates across a wide temperature range for dependable performance in varied environments.

Suitable for

• Watches and wrist devices
• Calculators and small electronic tools
• Medical devices (e.g., glucose meters) and health monitors
• Key fobs and remote controls
• Memory backup and small sensors
