Setup, Compatibility & Care
To install a Varta CR2025 battery, ensure your device is powered off. Open the battery compartment cover, typically found on the back or bottom of the electronic unit, and insert the battery with the positive (+) side facing up, matching the polarity indicated by the device.
Compatibility Note: Always verify the battery size indicated in your device manual. While CR2025 and CR2032 batteries look similar, the CR2025 is 0.7mm thinner and may cause loose connections if used in a device designed strictly for a CR2032.
Care Instructions: Keep batteries in their original blister packaging until use to prevent short-circuiting. Store in a cool, dry place away from metallic objects like coins or keys.
