How do I replace the battery in my SIGMA BC 12.0 WR/WL bike computer?

Replacing the battery in your SIGMA BC 12.0 WR/WL cycling computer is straightforward. Here's a step-by-step guide to keep your device powered: First, know that both the BC 12.0 WR and WL models use a CR 2450, 3V battery. Expect approximately 3 to 4 years of battery life for the BC 12.0 WR and about 2 years for the BC 12.0 WL, assuming daily use of around an hour. To change the battery, begin by removing the cover on the back of your SIGMA BC 12.0 WR/WL. Carefully take out the old battery from its compartment, taking care not to damage any internal parts. Insert the new CR 2450, 3V battery, ensuring it's oriented correctly, with the positive and negative sides aligned as indicated in the compartment. Finally, close the battery compartment cover securely. After completing these steps, check to confirm that your SIGMA BC 12.0 WR/WL cycling computer is working correctly.
