I have mentioned in previous postings that one of my HR92s has consistently needed its batteries changing every three months over the last 5.5 years. As an experiment I changed to lithium batteries. I got 4 months out of them!

It’s definitely the HR92. I checked the location long ago.
After all these years I know almost to the day when the battery low warning will come up. I ought to have had it replaced long ago but too late now. It’s 4.5 years old. I have a spare HR92 I could put in place. Perhaps it is laziness I haven’t. But 4.5 years in and all works well. Optimisation a no no for me and the app could do with updating but other than that it is a great system. Particularly if once set it up you stop playing with it!
One of our HR92s is showing low battery but can't bring myself to change it yet
Was hoping for them to last till September/October then i'm going to change them all to Lithium in one go and see how long they last.
