Life Span of Batteries in Motion Sensors?


I have been looking at SS for a while to replace existing wireless system. One thing I have found was that the motion sensor batteries have a very short life span, they also were not giving any indication that the batteries had failed. The batteries were AA-sized Lithium and aren't cheap.

Was wondering if anyone has replaced theirs yet or gotten weak battery signal ?

Thanks !

I've had my system since

I've had my system since January and can tell you that so far it has not been a problem. I did have a defective battery in my keyfob (didn't work from the start), but they replaced that and everything has been working great since. Customer support has been top notch. Oh, and the motion sensor battery type is CR123A.

What kind of battery life are you getting with your current wireless system?

Well I am ashamed to say I

Well I am ashamed to say I don't know what the life has been so far. The system is three years old but I didn't test very often so not sure when they started to die. My real annoyance is that there was no indication, the system always armed as usual.

I didn't realize they weren't working since the installer had turned off the motion-LED to save battery power so I never knew when they were actually getting tripped. I like that these are different battery type.

Does the motion sensor show an indicator when its tripped?

Thanks !

Simplisafe sensors

Simplisafe sensors definitely warn you when the batteries die. I had a dud battery in a window sensor and each time I armed the system it announced the problem and showed me on the keypad, until I did something about it. They replaced it and it seems fine now.

The motion sensor does not have an LED, which I appreciate since I have one in my bedroom and I hate it when electronics have all those lights blinking all night!

Battery Life .... Is

Battery Life .... Is becoming an issue with the various entry sensors. The system is only going into it's second month and we just replaced our third sensor battery - we have thirteen sensors throught the house and with batteries at $5 each we are already down $15. I know that is not much but hopefully these three were just an anomaly - we had one bad sensor that was replaced. The batteries don't pull juice until the activation strip is pulled so they should not have been old? We have spread sheet set up to track life - hopefully it is more than a couple months each.....

Hi, That certainly


That certainly shouldn't be happening -- Entry sensor batteries should last 3-5 years. We'll contact your directly about replacing the faulty sensors, as we'd like to ensure that this doesn't happen again.
