![]() ![]() However, due to the varying current and operating temperature of the system, this figure will not be accurate.Īs per the circuit diagram below, you can use the CR2025 battery to power a 3V DC motor. So for our application that consumes only 20mA, the battery should last for 163/20) 8.15 hours. This means that if we draw 163mA, then our battery will last for 1 hour and, similarly, if we draw 81.5mA, the battery will last for 2 hours. Then, in that case, the capacity of our battery is 163mAh. The battery life depends on many parameters, such as operating temperature, discharge current, dynamic loads, etc.īut let us assume, for the sake of simplicity, that we are powering a normal load that consumes a constant current of 20mA at 20☌. The CR2025 is a commonly used battery for portable electronic applications. With just 0.7mm of difference, for as long as either fits in the battery compartment, they can be used interchangeably with minimal effect.ĭo note that the 2025, being the thinner of the two, will have slightly less storage reserve and will typically not last as long as a 2032. The CR2025 and CR2032 are both 3V button cells, have identical diameters, but the 2032 is 3.2mm thick while the 2025 is 2.5mm thick. Other Coin Cell Batteries: CR2032, CR2016, CR1220 Lightweight, High Voltage and High Energy DensityĮquivalent for CR2025 Battery: DL2025, BR2025 Lithium button or coin cell batteries are a bit expensive than alkaline, but last longer, weigh less and have a wide operating temperature range. Therefore, 20mm is the diameter of CR2025, and 2.5mm is the thickness. The name defines the size of the battery as for CR2025, the first two digits are for the diameter and the second for the height or thickness of tenths of mm. They are generally of a compact size, 5-25mm in diameter and 1-6mm in height. Coin cell batteries like CR2025 have many uses, they are usually used for small portable electronics devices such as: This video shows how to test your coin battery to know if it's bad or not.ĬR2025 is a coin cell battery.
