About the CR2032 battery
CR2032 is a 20 mm × 3.2 mm, 3 V lithium cell with a typical capacity of about 225 mAh. The same size is sold as DL2032, ECR2032, KCR2032, 5004LC. A CR2012 or CR2016 or CR2025 has the same diameter but is thinner, so it can fit loosely and runs down sooner. Stick with CR2032.
