CR2032 Battery: Benefits, Pinout and Datasheet

The CR2032 is a 3 volt lithium coin cell battery that powers many of most popular devices. 

These little batteries are known to be able to withstand a range of temperatures and has been operable in temperatures from -30°C to 85°C. 

In most cases under normal circumstances, these batteries last for 3-5 years. 

Their compact design makes them suitable for some of the slimmest of sensors. CR2032 batteries are a type of non-rechargeable lithium coin or “button” cell battery. 

The CR2032 battery has a voltage of up to 3 volts and a capacity of up to 240mAh. The CR2032 is the most common lithium cell battery in the world. The battery CR2032 is also known as BR2332, BR2032, DL2032, EA2032C, ECR2032, L2032, LF1/2V, LM2032, CR2032, CR2332, 2032, 5004LC, AWI L14,RFA-35 and Seiko SB-T15.
