Batteries included! I'm glad I purchased this! Also, glad there is a smaller version for our smaller rooms. When we moved into this home, the smoke detectors were over 10 years old & they were beeping incessantly because the batteries were low. They left wires dangling from the ceiling when we had to remove them. After installing this a couple of months ago, I can tell this is a quality product! Of course, it's nice to have peace of mind for our safety! I'm purchasing another one for our hallway, and I have recommended this brand of smoke detector to my family members for their homes. Review: Only had it a few days but it went up without a problem. Filled in the old holes of the previous detector and drilled two new ones. Easy. Used the plastic inserts for the screws. Left the supplied dust cover on the unit until ready to test. Looks good, too, not as ugly as the main competitor's unit. Like that it's 2 AA batteries rather than 9 volt. ## Features - DETECTS SMOKE: Sounds a loud 85-decibel alarm when smoke is detected - 3 long beeps with red LED light flashing in time, repeating. - ENHANCED SENSING TECHNOLOGY: Reduces false alarms often caused by cooking. Comprehensively tested to meet the latest UL standards, meets UL 217 9th Edition & FCC standards. - NO WIRING NEEDED: Operates on 2-AA alkaline batteries (included) providing easy installation, simply mount the bracket onto the ceiling and twist & click the 5-inch smoke alarm into the bracket. - SELF-TESTING ALARM: Internal components ensure alarm is always operating as expected. Not a substitute for a manual push test, perform a button test once per week to verify alarm operation. - 3 LED NOTIFICATIONS: LED lights indicate alarm status, green = normal operation, amber = operating error, red = smoke detected. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CX6RMV4B | | ASIN | B0CX6RMV4B | | Alarm | Smoke Detector | | Batteries | 2 AA batteries required.

Filled in the old holes of the previous detector and drilled two new ones. Easy. Used the plastic inserts for the screws. Left the supplied dust cover on the unit until ready to test. Looks good, too, not as ugly as the main competitor's unit. Like that it's 2 AA batteries rather than 9 volt. ### ⭐⭐⭐⭐ Review *by H***E on 25 July 2025* I like these smoke detectors, in general, as they do not react to cooking odors, However, the level of the actual alarm leaves something to be better desired. It is just not up to what level I expect an alarm level to be,.. to get a person's FULL ATTENTION!!...but at least I don't have any more false alarms from cooking vapors any more. THAT is a DEFINITE PLUS for this unit ## Frequently Bought Together - Kidde Smoke Detector, AA Battery Powered, LED Warning Light Indicators - Kidde Carbon Monoxide Detector, Plug In Wall with AA Battery Backup, Test-Hush Button - Kidde Carbon Monoxide Detector, Battery Powered CO Alarm with LEDs, Test-Reset Button, Low Battery Indicator, Portable --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/621672304-kidde-smoke-detector-aa-battery-powered-smoke-alarm-led-warning](https://www.desertcart.co.th/products/621672304-kidde-smoke-detector-aa-battery-powered-smoke-alarm-led-warning) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
