The smoke detector battery you can rely on! Many smoke detectors can only be operated with alkaline batteries. The high-quality alkaline batteries from Ansmann, specifically designed to meet the needs of smoke detectors, offer the highest level of reliability and safety.

Long-lasting: The alkaline batteries provide you with reliable performance and a long lifespan, making them ideal for use in smoke detectors. The next battery change and the unpleasant beep of "low battery" in the smoke detector will be a long time coming, and the cumbersome battery replacement is rarely necessary. You also have the peace of mind that your smoke detectors will function properly in an emergency and will not fail due to a weak battery.

Tested quality: ANSMANN batteries have been successfully tested for electrical, thermal, geometric, and mechanical requirements. Through rigorous testing in Germany and the Far East, we can ensure the highest product quality. Our quality experts regularly monitor compliance with our high standards as well as international standards.

Top performance even at extreme temperatures from -10°C to +50°C: The powerful 9V block battery from ANSMANN is resistant to extremely cold and hot temperatures. It maintains its performance in smoke detectors even in unheated spaces (e.g., at sub-zero temperatures in a barn or garden shed) or during extreme heat.
