As you know, many of us are having issues with numerous aspects of our sentinels. As I have mentioned in previous posts, I have my 16 deployed in several locations. One of the locations is my warehouse. Truck drivers are carrying them, I have them attached to forklifts and other materials handling equipment that moves around constantly. Some are crisscrossing the US in trucks right now. But obviously I have them all registered in the app and I know where most of them are in a general sense.
I decided to walk the warehouse today with the app fired up (there’s a bridge in the warehouse as well) and started trying to locate the 4 I knew for sure were there. The app located two of them no problem. But the other two, despite standing right next to them could not be found. That is until I pressed the button on them.
So I started thinking about what could cause a problem like that. Yes, I understand we are on beta firmware but still, why do some seem to work fine and others not so good?
Then it dawned on me! I wonder if the batteries are good. I work with a ton of wireless A/V equipment. Battery strength has a huge impact on the functionality of these devices. So much so, that we have a standing rule that all battery operated wireless devices get fresh batteries daily on show sites. So I decided to pop a few sentinels and check the batteries. I think my pic will be self-explanatory.
My guess is that these batteries were purchased in bulk sometime last year. XYO claims a 5 year battery life. I know there ain’t no such thing as a 5 year battery for any electronic device that broadcasts and receives RF. The more a device transmits and receives, the faster that battery is going to die.
So my advice to all of you is buy a cheap little battery checker like the one pictured and check your sentinel batteries. I went one step further and grabbed a VOM to see what the actual voltage was(they are 3V lithium) and wow, 1.8 volts! This battery is on its last legs!
The sentinels make at least 4 different sounds from my observations and one of them could be a low bat alert. But who knows? I can’t find anything about the meaning of the different alert sounds beyond the initial two it makes when registering them in the app. Check your kits folks and replace batteries that are below 2.5Vs.
