Varta CR2032 Coin Cell Battery – 3 V Lithium-Manganese Dioxide Power Cell
The Varta CR2032 is a single-use coin cell battery delivering 3 V via a lithium-manganese dioxide chemical system. It is designed for compact electronic devices requiring a reliable, long-lasting power source in a minimal form factor.
3 V output provides stable power for memory backup, remote controls, and small electronic devices
Lithium-manganese dioxide chemistry delivers a long shelf life and consistent performance across a wide temperature range
Compact coin cell format fits into devices with limited battery compartment space
3 g lightweight design ensures minimal impact on device weight and balance
What sets the Varta CR2032 apart
As a primary (non-rechargeable) cell, the CR2032 is optimised for applications where a permanent, maintenance-free power supply is needed. The lithium-manganese dioxide system offers higher energy density and lower self-discharge compared to alkaline alternatives, making it suitable for devices that sit idle for extended periods.
Ideal for...
Remote controls, computer motherboard CMOS memory backup, car key fobs, digital scales, small LED flashlights, and other low-drain electronic devices. The CR2032 is the most common coin cell size and fits the majority of devices designed for this format.
Application of the Varta CR2032
Insert the battery with the positive (+) side facing up, matching the orientation markings in the device compartment
Ensure the battery is fully seated and the compartment closes securely
Replace the battery when device performance drops or after approximately 36 months of storage
