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 0.19mA 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 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.
