Fob batteries? Why do I keep burning through them?

I get a couple years out of the Tacoma fob, and 4-6 months out of the 4Runner fob.
Both proximity keys.
Who knows...

 

cheap batteries? one of the sets i got from Amazon are complete trash. i put them in airtags and immediately get low battery warnings.

 

The batteries that you see above in the picture where purchased on Amazon.ca I have used them on numerous electronic equipment guitar tuner, fobs ( Venza) and some remotes that require and they work great and long lasting. I don't see any name brand on them except CR 2032 Lithium OEM. presuming it means Original Equipment Manufacturer.

 

Old thread, great info here.

 

I have the best luck with the Japanese made Maxell and Swiss made Renata batteries. Never buy batteries from Amazon. Between the fakes and old stock, it isn’t worth the hassle. I buy mine from Battery Junction.

 

Every battery I've bought has been a crapshoot.

I've overpaid for local genuine energizer's. I've bought the cheap Amazon's, the unique japans...

Sometimes it's just a bad batch
