It is not the contacts. They have been checked, cleaned etc a few times and also checked that there is a good tight fit. Also I don’t think bad contacts would result in a signal to base at very regular intervals of 3 months. I should have put the batteries to one side to check but unfortunately put them in a bag of other used batteries to be dropped off at a collecting point and I can’t identify which they will have been. I’ll know by March!

Replacements? I use Energizer Lithium. Remember to change the battery type in the menu if you use these. But the last for YONKS!

With respect to my odd HR92 it is now used in another zone and I won’t know until March whether it has been the location at fault or the HR92. If the batteries need replacing in March then it’s the HR92.

It is not March yet, not far off, but the batteries need replacing and thus it is the HR92 eating them. After the last battery change I changed the position of the HR92 swapping it from one zone to another and for the past few months it has been alongside me and about 3 feet or so from the control panel. The signal has come up saying the batteries need changing. I have had this one since December 2014. Fair to say it has always been like this. I suppose even after 2.5 years it is still a manufacturer's defect. All the other HR92s are fine.
