It lasts a long time. If you let it go completely out it may last 2 years.I try to change them once a year. And yes it will let you know its low.

My battery has lasted a few years. It alerts you by the lights blinking red then green.

Mine hasn't gone out but it says it alerts you I'll probably change when I change my smoke alarm batteries. . Still can't express how much I LOVE this lock and how nice the unit is

The battery seems to last a long time .I have had mine for over two years and I may have replaced the batteries once but I am not even sure about that. Bottom line is: how long the battery lasts should not even be a consideration when deciding to buy. I love the darn thing. I just wish I could find out how to turn the alarm off.

This alarm will NOT alert you that it has been set off... it's only $16... it's just an alarm. If you want something that will alert you in any way, it's going to cost quite a bit more money I'd imagine.

Once the battery dies in the sensor, that particular sensor will no longer send a signal to the main alarm unit. I'm finding that the batteries are lasting about 6-8 months.

it does have an alarm...you can set it to a radio station or the alarm that's built in it...but no choice of different sounds...

This wireless smoke detector cannot be used as a stand-alone smoke detector. It must be programmed into a Honeywell alarm system to function as intended. It uses a CR123A lithium battery that lasts about 5 to 7 years. When the battery needs replacing, it will indicate this on the alarm keypad by beeping and displaying "BAT". The unit itself does not chirp to indicate a low battery but it does have a built-in sounder for when smoke is detected.

This model does not have a battery in it. It gets its power from the main alarm system board. If your alarm system is working everywhere else except this sensor then it would appear that the sensor is not working any more. Make sure the rest of your alarm system is working properly before replacing the sensor. It might just be a loose wire in the sensor circuit.

Mine needed new batteries after a year. The batteries are available at Walmart for almost $6 EACH. Because it requires THREE batteries, it's cheaper to replace the alarm than purchase batteries.

not sure either?mine lasted almost 2yrs and liked it. but when it stopped working right, I got NO help from customer service.so got another similar system about 3 months ago...and its a bit better I think for about same cost.called "MACE" home alarm.

If by silent alarm means nothing is felt, heard, or seen when you want it to alarm then YES! :) Unfortunately, this does not have any alarm nor any type of audible or mechanical notification. It is a trade off for having a device whose battery lasts up to a year.

Michael: Yes, the alarm unit resets after going off. It sounds for about 1 minute and it has a setting of high or low. I bought 4 of these units, 2 for RV and 2 for home. It can also be used for doors too as it can 'hear'. It uses 2 AAA batteries. Great product for security and advance warning.

I have had mine for years and years but I can't really answer! I use the alarm sound which will go off ten separate times probably 30 sec. Or so apart. I have had on since around 1978-ish and am only on my second one. I t is set for 4 separate alarms. I love the convenience of being able to grab my alarm and a couple containers when we go to my son's for an overnight. Good size too for the purse don't you agree? If you haven't purchased it yet I suggest you do. Enjoy.

The batteries will last approximately two years when in standby mode. If the alarm is sounding continuously, the batteries will last approximately five hours. With normal use the alarm will not constantly be in standby mode or sounding continuously. Therefore, the user can expect the batteries to last anywhere from 3-12 months depending on how often the alarm is activated.

Could be several possibilities. Check to see if your battery is older or not sufficiently holding a charge and or that all the connections and cables are clean and tight. You don't mention whether your alarm goes off constantly however even if it did you would have to try a different sensitivity setting and you may still have to refer back to the above assuming the unit is not defective in some way. Disconnectthe alarm and see if your battery still goes dead. if it does then you have a short or another problem or possibly something i mentioned. Good luck.

No low battery indicator. If you cover the unit in your hand you can muffle the sound and remove the pin to test it once a week. I got this for my daughter and its cool to hook on a purse, jacket zipper or a belt loop. No fumbling to push a button, just pull and it goes pretty loud.

Yes. It has dual alarm clocks. Also, although I'm not aware of it having a battery, every time the power goes out (for several days recently), it maintains the time, even though it doesn't function. Kind of a nice feature for middle of the night power outages - the alarm still goes on in the morning!
