Kidde Battery-Powered Carbon Monoxide Detector, COBDL with Low-Level Alerts

The Kidde COBDL is a battery-powered carbon monoxide detector for residential spaces, with low-level alerts and two included AA batteries for monitoring without wiring.

• 85-decibel alarm with a separate pattern for dangerous CO levels — signals when occupants should move to fresh air.
• Backlit digital display and LED status indicators — make readings and alarm status easier to see.
• Peak-level memory — shows the highest CO concentration recorded since the last reset.
• Wall-mount or tabletop placement, with mounting hardware included — suits different home setups.
• Test/Hush button — supports function checks and temporarily silences alerts when conditions are safe.
• Meets UL 2034, 5th Edition standards, is ETL listed, and includes a 10-year limited alarm warranty.

Carbon monoxide can be difficult to detect without an alarm, and children, older adults, pregnant women, and pets may be more vulnerable to low concentrations. The COBDL is designed for everyday residential monitoring at home, and its portable format can also be taken for use in hotels or vacation rentals.

What CO levels does the Kidde COBDL detect?

The detector provides an early alert at 30–70 ppm, using a distinct light and sound pattern. At 70 ppm, a separate alarm pattern signals dangerous levels for all occupants. Its low-level technology is intended to support earlier awareness for young children, older adults, pregnant women, and pets, who may be affected faster by low CO levels.

• Monitors for carbon monoxide and signals occupants to move to fresh air.
• A warning LED indicates a hazard alongside the audible alarm.

How is the detector powered and placed?

The Kidde COBDL operates on two included AA batteries, so it installs without wiring and continues working during a power outage. Place it on a table or use the included mounting hardware to install it on a wall. The backlit digital display shows CO information, while LED indicators communicate status.

• Battery operation suits spaces where wired installation is not wanted.
• Use the Test/Hush button to check operation or temporarily silence an alert when conditions are safe.
• The memory feature retains the highest CO concentration recorded since the last reset.

Can the Kidde COBDL be used while traveling?

The compact, lightweight detector is designed for use at home or in hotels and vacation rentals. It is for conditioned spaces only and is not approved for RV or boat use. For travel, pack it carefully to help prevent damage, remove the batteries before traveling, and reinsert them after arrival. Test the device before use to confirm proper operation.

• Portable design supports taking CO detection away from home.
• Travel preparation includes removing and later reinstalling the batteries.

What testing and warranty apply?

The Kidde COBDL is rigorously tested to meet UL 2034, 5th Edition standards and is ETL listed. The alarm includes a 10-year limited warranty. These details make it suitable for renters and homeowners seeking a residential CO alarm with documented standards testing and a stated manufacturer warranty.

• Designed for dependable carbon monoxide monitoring in residential use.
• Supports added awareness for households with children, older adults, or pets.

The Kidde COBDL is a fit for renters, homeowners, and travelers who want battery-powered CO monitoring, including households seeking low-level alerts for more vulnerable occupants.
