Leak Detector battery reads negative/incorrect values


Negative Value: The negative value your Leak Detectors report is a bug in the battery level algorithm. We'll be releasing a fix for it shortly.

Incorrect Values: As for the incorrect levels and minor deviations, our Leak Detectors use Lithium Thionyl Chloride batteries that have a very flat discharge curve.




A direct voltage measurement can't give you information about the capacity, so we have an algorithm that takes into account the voltage droop under load and the amount of activity in its lifetime. There is a small bug that exaggerates the impact of some events.

To fix this issue please make sure your iOS app is updated to version 2.15 or higher.

  • So, the latest "new app" version is 1.1.12, also called "Guardian" on the iOS app store, with a white background and blue "G" icon. the old version has a blue background and white "G" icon. Make sure you have the most up to date one.

    I received a brand new unit with leak detector that I ordered online from Home Depot and when testing the battery with a multi-meter it read 0 volts. battery had a date of 11 Nov 2017 on it. I understand there was some kind of firmware and/or hardware bug on the leak detectors that caused the batteries run down faster than normal? Also, the battery came installed so if it sat on a shelf waiting to be sold for years (I bought mine in 2021 and battery date was 2017), then the battery would be running all that time. The "15 year battery" life advertised online and on packaging was less than 3 years since it was dead when I got it.
