LOLs -- I don't think so. I bought two, and on the first one (everyday SUV) I put in new batteries from the start. On the ProMaster, I was in a hurry and forgot about the batteries. With the weak batteries, some pressures would read 00 -- but some of the temperatures were correct. So I guess the "battery low" indicator is "funky readings".. . . Does it tell you when the sensor batteries are low? . . .
I have had the first one installed in the everyday SUV since July (with the new batteries then) and it has been flawless -- so it at least seems to go 4 months on the Eveready batteries.
