Which Battery Lasts Longer? CR2016, CR2025 or CR2032?

While all these batteries are lithium coin cell batteries, they have slightly different capacities, which affects their lifespan. Generally, CR2032 batteries have the highest capacity, followed by CR2025, and then CR2016. Therefore, a CR2032 would typically last the longest in a key fob. However, the actual lifespan depends heavily on usage.

What if I Use the Wrong Battery?
