What is the normal battery lifetime? 4 of mine started beeping after just 18 months.

From previous experience I had to change mine every 12 months. The nice feature about these units is that you can change the batterywithout taking the unit down from the ceiling. The little pop open door on the face makes changing batteries a snap !

I went to the manufactures website and they recommend replacing the battery twice a year. I find replacing it once a year works well.

I have not tried to track the battery life because ours so seldom need replacing. I am guessing we go 36 - 48 months. Of course, the battery is just back-up to the house electricity. You may want to contact Kidde.

It depends on the battery. I've used Duracell 9v's for the past 18 months in my leak alert's and they're still going. The device will beep when the battery is low and I've heard no beeps yet. Occasionally I touch the sensors with my wet finger and they're working fine.

So I just tested mine and it does beep about 4 times every 10 seconds but it's not too loud or intolerable. Justenough to create a sense of emergency. I sized mine out for 60+ min of Critical Communications runtime but these are really meant to be used for short-term save everything and shut down functionality. You may be able to turn the beeping off but honestly, it's not too obnoxious.

I have two of these. One of mine died recently too. It would beep repeatedly, start up and then just shut off. I didn't pursue it though because I had overfilled it and thought it could be water damage.

I installed my unit in November 2013. My "long-life" battery started chirping October 4, 2014. That is 11 months. About the same time span that the old 9 volt batteries. Disappointing....

Radio beeps when battery needs replacement. Battery life may be about 15 to 25 hours;Beware it only tunes European AM stations (9 mHz spacing - not 10 mHz as in US)

Can't really add much to other answers - never had this problem with mine - I agree that it must be the battery. Is it installed properly? If it's giving a short beep every 20 seconds - it's definitely the battery.

For me, playing audio from my tablet to this Bluetooth speaker, the speaker batteries lasted for a little over a total of 15 hours. When the battery starts getting low, the speaker beeps every few minutes without being obnoxious or interfering with the audio to which you are listening. Even then, I noticed that the speaker kept playing another 20 or 30 minutes before completely dying, so it isn't like some devices that warn you and then die 30 seconds later.

I installed mine Nov 2013 and replaced the batteries today, Mar 2015, not because it was beeping, but because my other two detectors installed at the same time, but a different type, both beeped for replacement within the last week so I decided to do a pre-emptive replacement since this detector is in the bedroom. Both batteries showed about 1.2v remaining power.

The product has an expiration date, which is usually up to 5 years . I usually just wait until it start beeping. If he product is still within the warranty period, kiddie is very good at replace the product.

I don't have the technical expertise to respond--except to say when the power goes out, I think you get 8 hours off the battery--when the electric is restored, I believe the battery recharges. I can tell you the original battery installed by Verizon started beeping (indicating it needed replacement) after a year. The one I purchased through Amazon has only beeped when the power fails. So far, so good.

That's approximately the date the sensors will start to deteriorate. It will start beeping and keep on so, until you change it out. It will also keep beeping even without a battery for some 3 or 4 days.

I own many of these and none beep; I think the beep would be a bother and just use more battery power. I love these superb devices and the simplicity of using them. I've had some over 10 years and all still operate fine. I take one any time I'm working on any circuit, no matter how simple.... and I use them.

mine beeps when I first plug it in to charge but stops when its charged. I always keep my pulled in. I go out every night to feed up which takes about 1 hr then I came in and put it back on charge. I've had my first one going on 3 yrs. or longer. Hope this helps.

After 18 months, according to Braun. But sometimes, the warning sing at the bottom display will turn on after 12

Is yours set right? Mine beeps 24 hrs a day - not a solid beep but an intermittent beep - about every 20 seconds or so. Haven't had any problems and the gophers are gone! Did you put it together according to the instructions?

Can hear beeping inside of a purse within 6 feet. Have tested with keys in separate room through 2 walls, approx 35 feet distance. Best to have someone to assist with search. Beeping will occur from individual remote and sensors when batteries are low. Initially, had to replace furnished batteries within a week, replaced and have been good for over 8 months.
