And, pulse drain in every 2 seconds *12 times/delay at 400 ohms is 6.8mA 2.7V. Can be used in a wide range of temperatures (-30☌ to +60☌) 5. When, performing Pulse Test at 25℃, continuous background drain at 15k ohms is 0.19mA 2.9V. Very low self-discharge long shelf life of up to 10 years 4. 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. By the time your CR2032 battery loses its charge, the highly reactive lithium. Sadly every battery will have some internal resistance associated with it which will prevent you from drawing maximum current from the battery. Thankfully, CR2032 batteries dont contain any toxic metals or reactive acids. The CR1632 datasheet also provides a neat graph to understand the sameĪnother 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. But these batteries are rated for small output current, so if our load is consuming only about 0.19mA then the battery should last for (130/0.19) 684 hours. This means that if we draw 130mA, then our battery will last for 1 hour and similarly if we draw 65mA then the battery will last for 2 hours. Then in that case the mAh capacity of our battery is 130mAh. But for the sake of simplicity let us assume that we power a normal load which is about 15K ohms at 20☌. The life time of the battery depends on the many parameters like operating temperature, discharge current, dynamic loads etc. The name CR1632 indicates that the battery is 16mm wide and 3.2mm thick. The CR1632 battery is very similar to CR2032 or CR2025 but they are not interchangeable because of their dimensions. It has a height of 3.2 mm and a diameter of 20 mm. Non-Rechargeable Lithium coin cell Battery It uses manganese dioxide lithium chemistry with a voltage of 3 volts and 225 mAh typical in capacity.Note: These batteries can be used only through a cell holder, soldering or tampering the battery is not recommended. 1632 means the maximum diameter is 16mm and the thickness is 3.2mm 2032 means the maximum diameter is 20mm and the thickness is 3.2mm the voltage of the two batteries is the same, the shape is similar, the biggest difference is. The lower side of the battery is the negative terminal. What is the difference between 16 16 are the dimensions (models) of the two-button batteries. The upper side where the markings are found is the positive terminal CR1632 is the lithium coin cell battery that is commonly used in portable electronics gadgets which consume low power like watches, toys, RFID readers etc.
