How long is the battery estimated to last for each sensor?

I don't know the answer to your question. I will tell you that this product would not come off when I needed to place air in the tire. I had to spend over $100 per tire to have all the valves replaced.

The sensors come with batteries, but depending where sensors are located in dwelling, might only last for 6 months

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.

In this sensor's normal operation, it stays triggered to ON for four minutes before resetting to OFF. If motion is repeatedly detected within 4 minutes, it stays ON. There are three sensitivity settings, at the most sensitive, it will pick up some rather slight movements. If you can set your program to monitor the status of the sensor to turn the light off after the sensor returns to off, that should work. If 4 minutes isn't enough delay, there is also a "Test" mode in this sensor that eliminates the 4 minute reset time and it will continue sending out ON signals every time motion is sensed. You could program in your own time delay in this mode. No clue on how it would affect the battery life.

Time to replace the battery. The A23 batteries included with the system are junk. A couple of my sensors only lasted 3 months. I bought energizer brand as replacements.

I have not timed it but would estimate it to be 15 to 20 seconds, but if you are within it's sensor range, it will remain on, unless you stop any movement.once you move again, it'll come back on.

I use my sensor pump all the time, many times a day. The batteries seem to last pretty long. I also have mine set on the lowest setting. In the beginning the light is green and the as the batteries get weaker it turns red. Don't replace the batteries until it stops working. Always keep an extra set on hand.

Battery life depends on how much time unit is in alarm condition. If it never goes off, they'll probably last a year, but it also depends on the batteries and the environmental conditions.

Sorry I have no idea since the last sensor I had never wore out. Anyways I think this product is a waste of money now given apps like RunKeeper.

At first it lasted for about 5 hours until I calibrated the battery, now I get close to 7 hours

The lithium battery supplied is designed to last the life of the detector. At that point, in my opinion, its probably best to go out and buy a new detector.

The batteries that came with the sensor about 2 months. A good alkaline battery maybe 4-6 months depending on the activity it gets. Ex. I put my backyard sensor up in January and haven't changed it. But my driveway sensor from January I changed in May and I bet it'll be due soon. I'm not sure what "zero delay" is, but mine sounds immediately upon motion and if motion is consistant it repeats with about a 2 second delay.

It seems like the battery life should be good for days on end. I think the battery will only use life after setting the alarm off several times over a period of time. I check at least once a week.

We have an older model, and have a recycle bin on the floor under the sensor. I have found if my wife puts something in the bin that blocks the sensor (a few inches away), then the batteries go dead in a few days. Otherwise, it usually more than a year between battery changes.

If I remember correctly there is an adjustment screw inside the sensor that determines how long the sensor stays on so I've checked that before I got another one

Hello Rebecca, The Battery Life Is Dependent On The Amount Of Tracking (Logging The Unit) You Are Doing. The Trackers Have A Battery Standby Life Of Up To 60 Days But Most People Dont Leave These On Standby. Ive Had Consistent Logging For Up To 11 Days. That Was Hourly Logging For 11 Straight Days. The Less You Track The Longer It Will Stay Charged. Hope This Answers Your Question, Thanks!
