all the calipers I have all eat the battery just sitting around .

Finally it seems there are rechargeable calipers

Gonna order some

HARDELL Rechargeable Digital Caliper, 6" Plastic Calipers with Large Orange Screen (Non-Backlit), Inch/mm, Auto-Off Micrometer – Everyday Caliper Measuring Tool for Woodworking, DIY & Household https://a.co/d/03gGFO5X
 
Looks like a built-in battery? That would give me extreme pause. I'd prefer 357s I can replace indefinitely.

The better Mitutoyos turn off and batteries last .....I dunno....long enough it's not a nuisance.

I've also got Mitutoyo solars that have never needed a battery.

Generally speaking, if your use case is infrequent enough that you can't justify some Mitutoyos, you're better off with basic dial calipers. I keep a set in every truck and even if I pull them out after 5 years, they work : D

I've got 3 calipers; good, better, best. It all depends on what I'm doing with them.
 
Rechargeable batteries have a finite lifetime too. When they go, you have a piece of junk.

Never understood what the problem with one of these was…

I wish people would just use dial calipers, they're easier to read than at first glance. Most all of them are both metric and SAE.

I would never buy a cheap dial caliper though. You need the mechanism to be of proper quality to be accurate and reliable. My mitutoyos, brown and sharp, and starrets are old but still perform like new. Never had to change the battery.

Regarding that rechargeable thing it's okay for the price so if you don't need something super accurate just rough accurate down to the single decimal millimeter with a probable +/- .2 mm accuracy and nothing more I think it'll be fine.
 
When I bought cheap calipers, I specifically sought out models that employ CR2032 lithium coin cells, instead of the xR44 button cells.

2032s have become cheap, and readily available, due to their widespread adoption in everyday applications.

I hear ya, but we know from results 357 buttons can last ~2 years. Mitutoyo has pulled it off (for decades).

Chinese manufacturers are simply too cheap to employ true shut down. Instead the display goes blank but it's still chewing power invisibly in the background.

My three 6" calipers have batteries in them constantly. They're used regularly so removing and inserting batts is flat out unrealistic. My fourth is solar and that's the REAL solution. It works in very low lighting -- lower than my failing eyes would ever want to do anything that requires a caliper.
 
I have a German made Kern dial and a Swiss made Brown & Sharpe digital, the battery in the B&S last a long time. I have a Starrett but it is in inch so to me its just not very useful like the rest of the inch stuff, metric only here.
