Knowing the technical details of the Samsung ICR18650 is essential if you're planning to use it in your projects or just want to understand its capabilities better. Here’s a rundown of the key specifications you should know: The nominal voltage is typically around 3.6V or 3.7V. This is the average voltage the battery will maintain during most of its discharge cycle. Make sure your device is compatible with this voltage! Capacity usually ranges from 2600mAh to 3000mAh (milliampere-hours). This tells you how much energy the battery can store. A higher mAh rating means longer run times for your devices. The standard charging voltage is usually 4.2V. It's super important not to exceed this voltage, as overcharging can be dangerous and reduce the battery's lifespan. The discharge current is something to watch. The continuous discharge current specifies how much current the battery can safely deliver continuously. This varies depending on the specific model, but it's usually around 5A to 20A. The maximum discharge current is the highest current the battery can handle for a short period. Exceeding this limit can damage the battery or even cause it to overheat. The internal resistance affects how efficiently the battery can deliver power. Lower internal resistance means better performance. For the Samsung ICR18650, this is generally quite low, contributing to its efficiency. Weight is usually around 45g to 48g. This is important if you're designing lightweight devices. The operating temperature range typically spans from -20°C to 60°C. However, performance can degrade at extreme temperatures. Knowing these specifications helps you choose the right battery for your needs and ensures you use it safely and effectively. Ignoring these specs can lead to poor performance, reduced battery life, or even dangerous situations. So, always check the datasheet for the specific model you're using! Whether you're building a custom electronic device or replacing a battery in an existing gadget, these specifications are your best friends. They give you the information you need to make informed decisions and get the most out of your Samsung ICR18650 Li-ion battery. Remember, a little bit of knowledge goes a long way in ensuring your devices run smoothly and safely!
