Features and Specifications Lithium Coin Cell Nominal Voltage: 3.0 Volts Maximum Current: 0.19A Non - Rechargeable Disposal battery Typical Capacity: 240 mAh 20☌ 15k Load Service Life: 720 Hrs 20☌ 15k Load Typical Weight: 3.0 grams (0.10 oz. Why?ĪNSMANN batteries are thoroughly tested for compliance with electrical, thermal, geometric and safety-related regulations. With this item in your cart, your shipping options will be limited to DHL. Lithium Battery Shipping: Due to courier restrictions, this product can only be shipped within England/Wales. Need a different size coin-cell battery? Just use the search function above to find what you need! There are many application of coin cell batteries, the below circuit shows you that how to connect a CR2032 coin cell battery with a simple LED circuit. CR2032 provide a nominal voltage of 3.0V, to power up a simple LED we need a minimum voltage of 2.2V so we have used the resistance for protection or current limiting.This is a high-quality ANSMANN CR2032 coin cell battery, with a nominal voltage of 3V and a nominal capacity of 230mAh. And, pulse drain in every 2 seconds *12 times/delay at 400 ohms is 6.8mA 2.7V. When, performing Pulse Test at 25℃, continuous background drain at 15k ohms is 0.193mA 2.9V. The lower the IR (Internal Resistance) the more current you will be able to draw from it and higher the efficiency of the battery will be, the IR of a battery will increase as it ages or due to its operating environment. Sadly every battery will have some internal resistance associated with it which will prevent you from drawing maximum current from the battery. The datasheet also provides a neat graph to understand the same.Īnother important parameter to consider while deciding your battery is the internal resistance of the battery. However this figure will not be accurate due to the varying current and operating temperature of the system. Ideal for a wide range of electronic devices like watches, calculators or key fobs. So for our application which consumes only 20mA the battery should last for (240/20) 12 hours. Lithium battery which provides long lasting power for high performance and operates over a wide temperature range. This means that if we draw 240mA, then our battery will last for 1 hour and similarly if we draw 120mA then the battery will last for 2 hours. Then in that case the mAh capacity of our battery is 240mAh. But for the sake of simplicity let us assume that we power a normal load which consumes a constant current of 20mA at 20☌. The life time of the battery depends on the many parameters like operating temperature, discharge current, dynamic loads etc. The CR2032 is a commonly used battery for portable electronics applications. How to calculate the run time of your CR2032 battery Lithium button or coin cell batteries are a bit costly than alkaline, but last longer, weigh less and have a wide operating temperature range.įor the Pulse Discharge and Continuous Discharge Characteristics check the attached CR2032 battery datasheet at the end of the page. So, according to this 20mm is the diameter of CR2032 and 3.2mm is the thickness. The name defines the size of the battery like for CR2032, the first two digits stands for diameter and second for height or thickness in tenths of mm. Typically they are of compact size, 5-25mm in diameter and 1-6mm in height. ![]() ![]() Note: Complete technical information can be found in the CR2032 Datasheet linked at the bottom of this page.Ĭoin cell batteries like CR2032 are generally used for small portable electronics devices such as wrist watches, pocket calculators, automobile key less entry transmitter and hearing aids. ![]()
