I Tested And Reviewed 10 Best Aa Batteries For Smoke Detectors (2023)

I recently had to replace my old Kidde Smoke detectors with the new ones, which required changing out the wiring. The installation process was relatively easy, as all I had to do was twist the wires and cover them with our existing wire covers. I replaced two detectors, and I was pleased to find that they are able to communicate with each other during testing. However, I am yet to determine whether the batteries will last for the promised 10 years, as my previous detectors had 9-volt batteries while these new ones use AA batteries.

One issue I encountered with these detectors is that my alarm started beeping every week, prompting me to replace the batteries. Unfortunately, the beeping persisted even after replacing the batteries with new ones on two separate occasions. The tab to open the battery compartment needs improvement, as it was difficult to manipulate. In fact, I had to resort to pulling on the wires to unplug them and access the batteries. This process was much simpler with my previous detectors, and I find it frustrating that changes were made when the old design was more user-friendly. As I write this review, my alarm is beeping again, which leads me to question if this particular device is defective. I have never experienced so many problems with a smoke alarm before.

On the positive side, these detectors are incredibly loud, making them highly effective in alerting me to potential dangers. I appreciate that they have different beep patterns for carbon monoxide and smoke alerts, which allows for easy differentiation. However, I have noticed that they can be slightly sensitive to humidity. Living in an area that typically experiences dry conditions, I was surprised when the alarm went off once due to high humidity levels in my house. This sensitivity may cause some concern during sleep, as it could startle me awake. Despite this, I replaced my 10-year-old Kiddie brand alarms with these new detectors, and my son was able to complete the installation in just 30 minutes. He did have to change out the wiring and the base plate, contrary to what was stated online, but overall, the process was manageable.

I purchased these detectors after my old model was discontinued, and the customer service team informed me that this new model was the closest compatible option for my wired system. I followed the provided instructions and installed the detectors without any issues. So far, everything is working as expected. While I am unsure if the AA batteries will last as long as the 9-volt batteries in my previous detectors, I am satisfied with their performance for now.

The smoke/carbon monoxide detector is highly recommended for its excellent performance and ease of installation. The device operates on 2 AA batteries, which are conveniently included and easily accessible for replacement. In my case, I upgraded an existing smoke detector, and the new unit seamlessly fit into the mounting bracket of the old one, making installation a breeze. The package also includes 2 screws and drywall anchors, eliminating the need for additional drilling.

One of the standout features of this detector is its ability to announce the specific threat, providing valuable information in case of an emergency. While I cannot personally attest to its smoke and carbon monoxide detection capabilities, I have had positive experiences with other Kidde products in the past, which gives me confidence in their reliability. Considering the potential life-saving nature of this device, it is reassuring to have a brand that consistently delivers dependable products.

Another notable advantage of this detector is its improved sensitivity, unlike my previous smoke alarm that would go off unnecessarily during showers or when cooking food with minimal smoke. This alone is a significant improvement and adds to the overall positive experience with this product.

The voice alert feature is another commendable aspect, offering clear warnings for potential dangers such as fire or carbon monoxide emissions. Additionally, the use of 2 AA batteries instead of a 9-volt battery is a welcome change, providing convenience and cost-effectiveness.

Due to my positive experience with another Kidde detector in my home, I decided to replace the failing alarms with this model. The fact that it is recommended for a 3-story house further emphasizes its reliability and effectiveness.

I wish I had read some reviews before purchasing these products. It would have saved me a lot of trouble. If you are adding the Kidde RF-SM-AC Hardwire Wireless Interconnect Smoke Alarm with Battery Backup to an existing wired smoke detector system, you need to replace at least one of the existing wired alarms with this model for them to interconnect. Replacing the alarm was a breeze, thanks to the converters that come with the detector. It only took me around 10 minutes to complete the installation. All I had to do was match the existing male plug to the right converter, attach it to the new Kidde alarm, install the new base plate using the existing holes, and attach the new alarm.

In total, the entire project, including installing three new wireless alarms, took me less than an hour. However, I would recommend doing some research beforehand to understand the process better.

For the installation, I used a wireless drill and a 1/8 drill bit. It was easy to mark the holes with the hardware provided, following the instructions on where to place the alarm. I made sure to avoid corners and areas near the water heater. After drilling the holes, I hammered in the anchors and secured the anchoring plate. Then, I added the batteries to the alarm. It's worth noting that there are no face plates for the battery compartment, and you need to push down on the last battery to ensure it's properly inserted.

Next, I set the code for all the detectors to communicate with each other. I simply used a pen to make the selection. After that, I attached the alarm by turning it clockwise until I heard the clicking noises, which took about a quarter turn. It's important to remember that these connectors communicate with each other and not over your home WiFi.

That's it! Once all the alarms were installed, I tested them by holding down the button on one of them for 5 seconds. All the alarms sounded, indicating that they were successfully interconnected. I checked each alarm individually and found that one wasn't working, but it turned out to be my mistake. I had set the wrong wireless code, so I had to return and change it to match the others.

For those interested, I purchased most of these detectors in November 2015, and they were manufactured in April 2015.

I recently purchased this smoke alarm and carbon monoxide detector to replace my old one that was constantly beeping.

The installation process was straightforward, thanks to the detailed installation guide provided in the product box. It includes all the necessary components, such as the alarm body, installation base, screws, and plastic wall plugs. There is even a warning sticker with instructions in case the alarm is triggered.

I particularly appreciated the option to download the Tuyasmart app for additional features. Although I was initially hesitant about introducing another device into my home network, my research on the app and its developer, Tuya, reassured me. The app downloaded quickly and did not require excessive permissions. Pairing the alarm with my smartphone was a simple process, and the app interface was clear and user-friendly. The added security measures, such as choosing a robust password, further increased my confidence in using the app.

These smoke detectors are truly impressive, especially if you're in need of placing them in small or hard-to-mount areas. I recently purchased them for my attic and crawl space, and they turned out to be the perfect solution.

Firstly, these smoke detectors have a sleek and modern design that adds a touch of elegance to any space. While aesthetics may not be the most important factor, it's certainly a nice bonus. Additionally, they come equipped with a bright LED strobe and emit a loud alarm that can easily be heard even during sleep.

Installation is a breeze with the included rear mount, which can be secured with anchors or wood screws. However, what sets these detectors apart is the magnetic mount that comes with each unit.

I received the detectors two weeks ago and immediately installed them. The challenge was to install them over existing fixtures for old wired smoke alarms. However, the mounting brackets fit perfectly, and the alarms powered on as soon as they were mounted, just as advertised. It has only been one week since installation, but so far, I am very happy with this product.

These smoke alarms offer good value for the money, as they are basic but effective in their functionality. The loud testing button ensures that they will wake you up in case of an emergency, providing an added sense of security. Installation is easy, and they can be conveniently replaced after 10 years.

One reviewer mentioned that they have not had any fires yet, so they cannot speak to the performance of the alarms in that regard. However, they mentioned their intention to update their review in case of an actual fire, which shows their dedication to providing accurate feedback.

Another customer specifically needed to replace an older model in their camper, and this smoke alarm was the perfect fit without requiring new mounting screw holes. This demonstrates the convenience and compatibility of the product. The customer expressed satisfaction with the solid build quality and the overall sense of safety it provides.

One reviewer mentioned that these smoke alarms are sensitive, as they went off when they were smoking around one during installation. This indicates that the alarms are responsive and can detect smoke effectively. The loud and high-pitched sound of the alarm was also noted, which can be beneficial in alerting individuals to potential dangers.

Lastly, the fast delivery and easy installation were appreciated by a customer who also liked the smaller size of these smoke alarms compared to the ones they replaced. This indicates that the product meets the customer's expectations in terms of convenience and functionality.

In my experience as a professional in the installation of low-voltage equipment, I must say that the smoke/CO detector I recently purchased is quite impressive. Its sleek and compact design makes it perfect for travel and it can easily blend with any ceiling due to its thinness. The installation process was simple and hassle-free.

One of the standout features of this detector is that it includes two devices, allowing for placement in multiple areas of the house, ensuring enhanced safety.

The alarm of these detectors is undeniably strong. Upon testing, I found that my neighbors were able to hear it clearly, providing assurance that it would be highly noticeable in case of an emergency.

After my old smoke alarm broke, I came across this new one and I must say, it exceeded my expectations. The installation process was a breeze, and upon testing it, I was pleasantly surprised by its loud alarm. This feature alone gives me peace of mind, knowing that it will alert me promptly in case of any potential danger.

One thing to note is that this smoke alarm is smaller in size compared to my previous one. While some may find this to be a disadvantage, I personally appreciate its compact design as it takes up less space and blends seamlessly with my home decor. However, for those looking to replace a larger smoke alarm, it might be worth considering the size difference.

In terms of performance, this alarm has proven to be reliable and accurate. It functions exactly as intended, effectively detecting smoke and providing timely alerts. Its dependability makes it an excellent choice for ensuring the safety of your home and loved ones.

Additionally, I found the installation process to be hassle-free. It doesn't require any complicated wiring and can be easily set up by following the provided instructions.

The DASINKO Carbon Monoxide Detector 3-Pack offers a convenient and reliable way to protect your home from the dangers of carbon monoxide. With its easy setup and user-friendly features, this detector provides peace of mind for you and your loved ones.

Setting up the detector is a breeze – simply remove the back, insert three AAA batteries, and you're good to go. Once the batteries are in, the device performs a quick test for two minutes before displaying the readings. You have the option to either place the detector on a shelf or mount it on the wall using the included screws.

I wanted to ensure the effectiveness of the detector, so I conducted a test by exposing it to smoke from a snuffed candle. The detector responded promptly, showing a reading of 79 for a couple of minutes before gradually returning to zero. This confirmed its ability to detect carbon monoxide effectively.

It is important to note that carbon monoxide is a man-made gas and does not occur naturally in the environment. If the levels in your home exceed 5PPM and you do not have a gas stove, it is crucial to investigate the source. For a healthy adult, levels below 50PPM for up to 8 hours are not worrisome, but it is always better to err on the side of caution.

The DASINKO Carbon Monoxide Detector 3-Pack operates based on specific alarm levels. For example, an alarm will sound if the levels reach 40PPM for 10 hours, 50PPM for 8 hours, 70PPM for 1 to 4 hours, 150PPM for 10 to 50 minutes, or 400PPM for 4 to 15 minutes. This ensures that you will be alerted if the carbon monoxide levels become harmful over sustained periods.

It is worth noting that carbon monoxide and carbon dioxide are different gases and require separate detectors. While carbon monoxide is a colorless, odorless, tasteless, and flammable gas, carbon dioxide is a colorless and non-flammable gas primarily used to check air quality. It is essential to have both detectors in your home for comprehensive protection.

In the United States, accidental exposure to carbon monoxide causes over 500 deaths and thousands of emergency cases each year. Whether it is due to house fires or faulty gas appliances, the consequences can be severe. Therefore, it is crucial to have a reliable carbon monoxide detector in your home.

From my experience, it is important to replace carbon monoxide detectors regularly, regardless of their price range. While it is recommended to change the batteries every one to two years, the device itself should also be replaced periodically to ensure optimal functionality.

The DASINKO Carbon Monoxide Detector 3-Pack is an excellent choice as it offers three detectors in one package. This allows you to keep spares or share them with family, friends, or neighbors. At a price of $40 for three detectors, it is an affordable option.

Using the device is straightforward – insert three AAA batteries (not included), and the LCD screen will display the parts per million (PPM) reading. The detector also features a test/reset button for convenience. A voice prompt guides you through the setup process, and the red LED flashes every 30 seconds to indicate proper functioning. The alarm level is clearly displayed on the LCD screen.

When the detector detects carbon monoxide levels exceeding 30PPM, it sounds an alarm accompanied by a voice prompt. Additionally, it alerts you if the batteries are low or if there is a sensor failure, ensuring continuous protection.

The DASINKO Carbon Monoxide Detector 3-Pack comes with mounting accessories, providing flexibility in installation. Overall, this detector is highly recommended for its ease of use, reliability, and affordability. Invest in the safety of your home and loved ones by choosing the DASINKO Carbon Monoxide Detector 3-Pack.
