the batteries

A 100+ PSI gauge may not be very accurate at low pressures. I'd spring for another digital, some batteries for it, or a quality 0-50 PSI car tire gauge.

Milton brand is usually good quality.....not the $2 gauges in the checkout lane at Wallyworld.

I have a digital Tekton that would be easy to replace the coin cells in.... yours may be similar.

Yes that's what I kinda thought too..

I have a quality digital Michelin tire gauge that im going to
replace the 2 cell batteries and use from now on. I read online that
digital tire gauges recalibrate themselves after a reset wich is a cool
feature to have for accurate tire pressures.
thanks all for posting...

Until the pressure sensor goes screwy.
I've got a digital bathroom scale that's supposed to do the same thing. It has a strain gauge inside it.

A couple years ago the display was fading, so I cracked the scale open and replaced the batteries in it....(sealed unit, not user serviceable)
Now I think maybe I should have just got another one instead of opening it up and replacing the batteries because lately it's been acting a bit wonky when I weigh myself...

According to this scale I may have lost anywhere from 0-25 lbs, but my pants still fit about the same every day.
