Kidde Carbon Monoxide Detector COBD10 — 10-Year Battery, Backlit Digital Display & 85 dB Alarm

The Kidde COBD10 is a battery-powered carbon monoxide alarm with a built-in 10-year battery, backlit digital display, and an 85 dB alert to help detect and warn of CO presence in your home.

This compact Kidde carbon monoxide detector combines long-life power, clear status feedback, and established safety testing to deliver continuous CO monitoring without frequent battery changes. Its backlit digital readout shows real-time CO concentration and the highest level recorded, while LED indicators and a loud alarm provide visual and audible cues. ETL listed and tested to UL 2034 5th Edition, the COBD10 is designed for straightforward placement and everyday residential use.

How does the COBD10 let me know there’s carbon monoxide?

The COBD10 uses an audible 85-decibel alarm paired with LED status lights and a backlit digital display to communicate hazards. When elevated CO levels are detected, the alarm sounds and the display shows concentration in parts per million; LED indicators show normal operation or hazard status.

• Loud 85 dB alarm for immediate audible warning
• Backlit digital readout shows current and peak CO readings
• LED indicator lights for quick visual confirmation of status
• Test/Hush button for momentary silence and function checks

What makes the 10-year battery important for home use?

A sealed, maintenance-free 10-year battery eliminates regular battery replacements and prevents recurring low-battery chirps that can be disruptive. This long-life design reduces upkeep and can save money over the life of the alarm while ensuring continuous protection without user intervention.

• Built-in 10-year battery for uninterrupted monitoring
• No regular battery swaps or low-battery chirping
• Replacement reminder after 10 years to update your alarm
• Cost savings compared with frequent battery-powered models

How easy is it to install and operate the Kidde COBD10?

Installation and daily use are simple: mount the unit on a wall, or place it on a table or shelf using the included hardware. The test/hush button performs quick system checks and temporarily silences nuisance alarms, while the memory feature displays the highest CO concentration recorded since the last reset.

• Wall-mount or tabletop placement for flexible coverage
• Mounting hardware included for fast setup
• Test/Hush button for quick verification and temporary silence
• Memory resets to show highest recorded CO level since last reset

Is the COBD10 a trusted and code-compliant choice?

The COBD10 is ETL listed and tested to UL 2034 5th Edition standards, meeting recognized safety benchmarks for residential carbon monoxide alarms. Kidde backs the alarm with a 10-year limited warranty on the unit itself, reflecting its design for ongoing household use.

• ETL listed and meets UL 2034 5th Edition testing standards
• 10-year limited warranty on the alarm (not a battery performance warranty)
