Uses a stack of 3 LR44, according to the website.

Learned long ago that it's better to stick with analog gauges if you intend to store it in the car. Batteries always seem to be dead when you need to actually use the gauge. And removing the batteries when stored to prevent drain kinda defeats the purpose of convenience, especially when they still end up dying.

Just don't use those pencil gauges. They are wildly inaccurate.

But I have a many years old digital gauge (Accu something or another) that I keep in the glove box and the car sits in the sun. I check my tire pressure regularly and can't remember when I last changed the battery. It just always works when I need it. Perhaps you need a new gauge from a different brand?
Same. I live in Vermont where the temp over the year swings from 100 degrees to -20 degrees. I have two different battery gauges stored in my cars and have never had a problem with battery life.

One should aways check the tire pressure once a month, when COLD. The most efficient strategy is to secure a high volume air pump and check the tire pressure in the morning when the vehicle is parked at home. Keep a tire plug kit and a hand pump in the car for emergency. After repair, add air so that the tire bulge is similar to the bulge on the other side. Recheck the tire pressure when cold.
Unrealistic. OR, if you're checking your tires monthly you should also pop your hood and check your oil and perform a multi-point inspection.

It's a great thing that modern vehicles provide the tire pressure warning so we can use tools like the above (or an analog one. Doesn't matter) to heed that warning and safely get the additional air...or look towards patching/replacing

I too have like a craftsman that I bought from Sears in the mid 2000's and it still works today. I think for the most part a tire gauge is just fighting battery corrosion and if it doesn't happen due tp a proper sealing it's going to last decades.

It's still a dimly lit blue light and I still use it for no more than 2 mins max as it's quick to check tire gauges.

Well, what's wrong with the analog one? No battery required.

This was rated well on ProjectFarm within 0.5PSI. that tested at both hot and cold. The top rated one is $25

I don't own craps that burn 1 qt of oil every 1000 miles. The 201K mile Corolla uses 1/8 quart of oil every 5K. Quick visual inspection under the hood at 5K OCI is more than adequate for a well maintained vehicle.

A car that tracks true above 30 mph will pull to one side if one of the tire is underinflated by about 5-6 psi. Visual inspection at the contact patch will show excessive sidewall bulging. Most warning systems won't trigger unless the delta is more than 3-4 psi.

My T300 is accurate to 0.1 psi from 0-150 psi (Fluke 2700 Reference Pressure Gauge used for testing at 45 F and 100 F ambient). Very impressive for a $4 item.

For those that use rechargeable batteries they make a model which uses two AAA batteries it costs more though.

I've had one of these for about two years. I'd rate it 3 out of 5 stars. My biggest complaint is that the connection it makes with the valve is unreliable.
The pressure gauge listed here a few days ago has an elongated opening to receive the valve and I've found it more reliable; it gets a reading on the first attempt with little lost air.

Opted for your suggestion.
0.50¢ more plus additional pennies on tax. Uses AAA vs LR44 batteries (which I have but my AAA supply is more robust). Thank you.

I had one of these. Same shape, color, function, but put out by a different Chinese company. Worked great for almost a year, then the batteries died. I changed the batteries and it was still dead.
So I ended up going back to the silver pen shaped manual tire gauge.....

Quote from E4300 :
You are repairing a flat tire on the road. Number one goal is to get home and wait overnight for the internal tire temperature of all tires to equalize before you use a tire gauge!
I reread your OP and it wasn't very clear that you were talking about repairing a tire on a road. Regardless, you still have a gauge and should use it, even if the tire isn't perfectly cold.

Then there is the issue that no one repairs tires on the road any longer. They put the spare on from the trunk or they call road service. Do you carry a tube repair kit for your car tires? Do you use a lighter to heat the glue before applying the patch, like my daddy taught me? Best to make sure you have a lighter than also! [rotlol]

I honestly cannot remember the last time my cars had a actual flat tire. It is certainly more than 20 years.

I told my kids to check the pressure quarterly. I can guarantee they've done this exactly zero times.
