Hi. How long does the batteries last in sensors?

Normal 6 months to one year, if it is original batteries from box, it may not fresh as we need store it inside warehouse for a while, you may change it soon

Next week my SmartThings will turn 1 year old. Here are my current battery readings for each of my original devices and their function: Motion sensor in my living room that gets lots of use: 13% (uses AA batteries) Garage Door Smart Sense Multi (this product) which gets opened and closed at least twice a day (maybe more and sometimes stays open all day): 50% (uses AAAA batteries) Garage People Door SSM (this product) (entry to/from garage into house) which gets opened at least a dozen times a day (wife and kids): 50% (this is after an entire year!!) Garage Motion Detector which sits in garage for security purposes: 13% (uses AA batteries) So despite some who think that the usage determines battery life, it would appear in my situation that my devices are wearing evenly despite differing usage patterns.

Depending on the frequency of use of the garage door, the sensor battery should last approximately 10,000 cycles (1 cycle is an open and close action). On average, this would equate to about 3 years. The sensor will alert your app when it approaches this figure.

I didn't do any scientific measurement. My opnion is therefore subjecive. It appears that these batteries do last. This key is to get them fresh. Batteries do lose power with time if you let them sit. Some lithium button batteries that I purchased on e-bay were two years old and lasted about a week in my guitar tuner, which is way too short. I blame it on the age of the batteries. Those 9 volt lithium batteries don't seem to have this issue. We'll see in a few years.

They last pretty long. Make sure you use quality batteries, like Duracell or Energizer. Don't forget to turn them off when not in use. I don't want to attempt to guesstimate how many hours, but we really don't have to change them often. If they start making funny noises, time to change batteries.

Thanks. How many batteries? According to your experiences, do they last for 7 months as expected?

Mine are lasting for over 1.5h and they outrun oem GoPro batteries by just few minutes. The real test comes after several charges but I don't have any complains so far. Good luck with your shooting;)

AA batteries. Depending how many times the alarm goes off, they should last approximately 6 months.

I had fantastic luck with regular double A batteries as well. Generally, they would last for maybe about 8 hours of life, and I always got accurate battery life readouts, and was always able to replace them when they got low without any issues.

Yes, my batteries lasted a short time also. I purchased rechargeable ones & the charge has lasted so far 4 months.

The first set of Duracell batteries in one light on our front porch (activated a few times a night on average) lasted for four years. I had to replace them earlier this year so i don't know how long these second set will last.

Mine are still on the original batteries and I've used them through 3 dinner parties. They have run approximately 12 hours for me and there is still light. They are led lights so they pull very little off the batteries.

The batteries with intermittent use, lasted about 4 1/2 to five months. It may have been a bit longer, but no more then 6 months. I don't have any complaints. The screen shows enough detail with a night light outside.

I have 2... They last about 4-6 months it seems like, depending on how much activity they transmit. The sensor on your front door is going to use more power than a side door. Just my experience.

All the sensors have batteries included, they are lithium I think (cant remember) and are odd size ( much shorter than an aaa). My parents system is still going after several years so they are good ones!

I use these batteries in some burglar alarm sensors, and mark the date of installation. Most of the time (in at least half a dozen instances), I will get between 2 - 3.5 years of service on the Ultralife batteries. It's not 10 years, but it is far more than I would get from a standard alkaline.

Sylvia, I bought and installed 2 cameras back in March, in addition to the batteries included with the cameras I am now on my 3rd set of batteries so I would say they last between 3 to 4 months. Hope this helps.
