Auxiliary Siren batteries only lasting 4-5 months
When I got my Auxiliary Siren the initial batteries only lasted about 6 months. I assumed it was because they may have lost a charge while in storage. Replaced with some brand new batteries and this time they only lasted 4 months before I got a low battery warning.
Is this normal? The website says 8-12 months for the Siren.

Hi @Howie411 ,
Yes, the expected battery life for those AA alkalines is about 8-12 months. Battery performance might decrease if the unit is forced to work harder to maintain its connection with the Base Station - for example, if it's very far, or if there's a lot of interference in between. Where is your siren located in relation to the Base Station? It might help to move one or the other to a different spot for better connnectivity.

Lucky you! Even with expensive lithium batteries mine only last about a month! Called and was sent a replacement. SAME problem. This one went 4 weeks!

I have placed it next to the base station to aovid the possible "interference" issue you had mentioned. My replacement siren still only last for about one week. Now they are sending me the 2nd replacement after troubleshooting everything although I am not positive it is going to resolve the problem. Very frustrating!

(how do you I start a new conversation? I'm not finding anything about AC powered sirens)
Good day all, I've not had the best battery life experience myself when it comes to the aux sirens but my concern is having installed a system out of state in a vacant unit. I'm eager to avoid this issue and have called SS a couple of times wondering why an AC powered option isn't offered? Hopefully, this is something in the works but I'd appreciate any updates.
Meantime, anyone see a noticeable difference between alkaline and lithium batteries?

My siren has all the sounds/beeps disabled and it's close to the main station but the batteries still last 1-2 months. It wasn't like that the first year. Very frustrating and a waste of money and batteries.
Any solutions?

I'm still reading this thread, but I recently replaced my siren batteries for the first time in ~35 months; just an FYI.

I just got two new sirens and they both are reading 'battery critically low'. They came with batteries inside and I pulled the battery tab. I changed the batteries wondering if they were just sent with bad batteries - same critically low battery message. The batteries can't be 'working too hard' like I see in this stream since they've been in the siren for 10 minutes by now total. They are sitting 2 ft from my home base (which is up to date). Any ideas? I worry about trying to exchange them since it's happening for both sirens...

FYI, I use a battery tester to check my batteries and like to get as much out of my batteries as possible before throwing batteries away. I've got several testers but my favorite testers are made by ZTS, the MBT-1 model may be overkill for most folks however. There might be other brands and models of testers out there. Do shop and research before buying.
Otherwise, I haven't had a bad siren issue or sirens reading wiith critically-low batteries unless my SimpliSafe batteries were indeed low.
