Kidde Worry-Free Carbon Monoxide Detector Alarm with 10 Year Sealed Battery | Model C3010

It would be very difficult to know if this detector works or not... but it shows like it is operational and I haven't died of carbon monoxide poisoning, so I trust it is working... the fact that the battery is for 10 years and I don't need to deal with annoying alarms in the middle of the night to replace the battery is a very nice thing to have... I do stare at it every now and then to see the little blink LED to see it is still powered... after months and months... still blinking...

This is our second pair of Kidde Carbon Monoxide Detector Alarms. The first pair lasted more than 10 years. Carbon Monoxide poisoning is a serious problem and everyone should have detectors.

Easy to install and activate. The instructions were clear enough that we were able to install without any issues. The detector makes an ear piercing beep when activated for the first time. I think they need to mention that in the instructions. I would buy again if I needed one.

I live in NJ they have a law for smoke detectors 10 year battery so I did the carbon monoxide detector 10 years also just incase! The law was made because people took batteries out of their smoke detectors to play video games! Very dangerous habit! Very good brand. Work when we tested it.

Prior C-O detector reached EOL (slightly early but older model only had 7 year warranty. Wanted similar Kiddie model so that installation would go exactly into the same spot. Simple enough, just had to replace bracket and used same screw holes in wall. Went for 10 year batters to avoid yearly chirping and replacing batteries.Ordered and came quickly. Price was decent, packaging good, and installation easy.I will update if battery/unit doesn't last full 10 years.

My old one with replaceable batteries just stopped working. Turns out the sensors on these die after 7 years as stated on the lable. So even after I replaced the battery, it still gives an error beep.Since these will only last a bit over 7 years, why not just pay a little extra for this 10 year battery one and don't have to be bothered for a decade. Good peace of mind. HIGHLY RECOMMENDED.

I ordered this to replace a different model of a Kiddie carbon monoxide detector. There's a lithium battery that is encased in the unit , that is due to last 10 years, and can't be replaced. Our old Kiddie we replaced the batteries numerous times, but it still only lasted 10 years, so it's probably cheaper than all the batteries we replaced over the years, and makes it maintenance free. The slots in back (there's 3, to perhaps accommodate the size of a previous unit - I needed 2) to hook it on matched the slots for the previous Kiddie so that made things easy.

I will not be climbing a ladder and replacing batteries twice a year for the next 10 years. Since carbon monoxide rises, the alarms should be placed on or close to the ceiling. I have hard wired smoke alarms, but there are no electrical boxes installed for carbon monoxide alarms. I had wanted to purchased plug in alarms, but normal outlet heights and locations are not the most effective locations for placing the alarms. I purchased one thinking that it had a remote sensor, but found that it had a plug in transformer and an 8 foot wire going to the alarm. It looked terrible draped down the wall and limited the locations were the alarm could be located. The 10 year battery is ideal, since the alarms themselves need to be replaced after 10 years anyway.
