Understanding CR2032 Batteries
Before diving into brands and specs, I made sure to understand what a CR2032 battery actually is.

- Stable Voltage Output: Consistent voltage ensures my devices run smoothly without sudden shutdowns.
- Leak Resistance: I wanted batteries that are less prone to leaking, as that can damage my electronics.
- Value Packs: Buying multi-packs gave me more batteries for less money, but I made sure each battery was from a reliable batch.
