The Kidde 30CUD10 is a battery-powered combination smoke and CO alarm from the DETECT line with a 10-year sealed lithium battery. No battery changes for 10 years — it avoids inconvenient replacements and saves up to $40 over the device's life. At end of life, the alarm beeps to remind you it is time to replace the unit. Cutting-edge sensing technology delivers fast alerts, while enhanced sensing technology reduces false alarms often caused by cooking. Self-testing components continuously verify the alarm is functioning as expected. Simple installation with the included twist-and-click mounting bracket.
Can I replace the battery in the 30CUD10?
No. The 30CUD10 uses a sealed 10-year lithium battery that cannot be replaced. The alarm is designed to be used for its full 10-year service life, then replaced as a complete unit. At end of life, the alarm beeps to signal it is time for replacement.
What is the difference between the 30CUD10 and 30CUD10-V?
The 30CUD10-V adds crystal-clear voice alerts that announce 'Fire!' or 'Warning! Carbon Monoxide' when an alarm triggers. Both models use the same 10-year sealed battery, DETECT sensing technology, and self-testing. Neither model interconnects with other alarms.
