The thickness of the each CR2032 battery is 3.2 mm, while most was 3.0 mm, ensuring its capacity to last for a longer time, the capacity probably vary if you use the thin one.because it is lower quality.
With lithium manganese dioxide (LiMnO₂) chemistry, the CR2032 battery has an impressive 3.0V output under different conditions. That type of chemistry is very stable, there is less reaction than other type of batteries.
The CR2032, therefore, does not heat, either in use or in storage, making it safer – particularly in terms of high-rate devices or aspects that require high ionic flow. Their stable battery chemistry holds its charge even when not in use so they are ready when needed; the battery temperature control prevents overheating, short circuiting, and overcharging.
