Harvesting 18650s from laptop batteries

18650 batteries are commonly used in laptops as a source of power. However, when the battery is no longer holding a charge, or when you need to replace it with a new one, you will need to remove the old battery. In this article, we will guide you through the process of removing 18650 batteries from laptop batteries.

Step 1: Prepare the tools

To remove the 18650 battery, you will need a set of screwdrivers, a pair of pliers, and a soldering iron. Make sure the screwdriver fits the screws in your laptop battery. Also, ensure the soldering iron has a small tip and is not too hot.
