What good batteries did you buy and from where?
Recently sub says I want to change my own batteries , I said carry on , after a few weeks of continuous tamper alarm alarms because they couldn't close covers properly, they kept getting low batteries, changed battery reset keeps coming back same problem
They bought as I suggested Duracell lithium cr123
Another few weeks still don't want to pay me to come , so I say carry on.....
Eventually they tell me, they bought them from Amazon general supplier (china copy maybe???)
I said buy them from somewhere else see what happens
Fault disappears and they return all the batteries bought from Amazon , woohoo ?
Problem here is Amazon or eBay or many places can't guarantee supply chain ?
Just a side story , where you buy your batteries from ? I don't think your sensor goes sleep either ....
