Cr1632 lithium battery11/30/2023 ![]() If you find this blog useful, please bookmark our website Apogeeweb, we will provide you with electronic component blogs, industry news, tools, etc. That’s all for our introduction to the CR1632 Lithium Coin Battery. And the pulse drain is 6.8mA 2.7V per 2 seconds *12 times/delay at 400 ohms. When conducting Pulse Test at 25☌, the continuous outflow at 15k ohms is 0.19mA 2.9V. The lower the IR (Internal Resistance) the more current you will draw from it and the higher the performance of the battery, the higher the IR of the battery as it ages or due to its operating environment. Unfortunately, any battery will have some internal resistance associated with it, which will prevent you from drawing the full current from the battery. The CR1632 data sheet also provides a neat graph that can be understood in the same way.Īnother important parameter to consider when deciding on your battery is the internal resistance of the battery. However, due to the varying current and operating temperature of the system, this figure will not be accurate. But these batteries are rated for a small output current, so if our load consumes 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, the battery will last for 2 hours. Then, in that case, the capacity of our battery is 130mAh. But let us assume, for simplicity's sake, that we are powering a normal load of about 15K ohms at 20☌. The battery life depends on many parameters, such as operating temperature, discharge current, dynamic loads, etc. ![]() The name of the CR1632 indicates that the battery is 16mm wide and 3.2mm thick. ![]() The CR1632 battery is very similar to CR2032 or CR2025 but is not interchangeable due to its size. Non-Rechargeable Lithium coin cell Battery.Note: These batteries can only be used through a cell holder, it is not recommended to solder or tamper the battery. The lower side of the battery is the negative terminal. The upper side where the markings are found is the positive terminal. There's a Video Introducing 7 Best CR1632 Batteries in 2020
