Definition: CR2032 Coin Cell Battery
A CR2032 coin cell battery is a non-rechargeable lithium cell coin shaped battery that is 20mm in diameter and 3.2mm in thickness. The CR2032 battery has a voltage of 3 volts and a capacity of up to 240mAh, depending on the manufacturer specifications. This battery format features a relatively high power capacity for its size, a high service life, and consistent discharge, making it the ideal choice for low-power and long-term use in electronic devices such as a Real Time Clock (RTC). These batteries may last several years before fully discharging in such applications.
