In this video we explain in easy to follow, step-by-step instructions how to replace the battery of the JBL Pulse3 wireless BLuetooth speaker. The process about 40 to 60 minutes to complete and requires small Philips screwdrivers, some wire cutters, a sharp blade or prying tools. It is faily complex to do, so some experience with working on electronics is of advantage. We also explain how to put the speaker back together once it is fully disassembled and the battery was replaced.
