Heh, we were stuck in a carpark for 3 hours because the 2025 battery cell in our key remote went dead on a cold walk around a local lake.

It's supposed to have a backup but, like most backups, I hadn't tested that it works and for some reason the RFID reader part wouldn't connect with the car.

Are 2025 battery cells batteries from the future?

assuming this is a cr2025 then most likely 20mm diameter and 2.5mm thick => 2025

this is the most useful thing I've learned so far this year

Yeah almost certainly talking about a CR2025.

Use of a 2025 cell would be rather irritating to me, because in my experience CR2016 or CR2032 are both more common, and it seems like it should not be hard to fit a 2032 into most keyfob designs.

A type of battery the small round one.. not the year

Thanks, that makes much more sense
