Introduction
Don’t toss those old cell phone batteries! With a bit of care and creativity, they can be transformed into functional power sources for small DIY projects. This guide shows practical, safe ways to give your old batteries a second life, reduce electronic waste, and explore home-based innovation.
Why Reuse Old Batteries?
Old cell phone batteries often still hold a charge and can power low-energy devices. Instead of ending up in the trash, they can:
Reduce electronic waste
Serve as energy sources for small DIY projects
Be a hands-on way to learn electronics or renewable energy concepts
Materials Needed
Old, functional cell phone batteries (not swollen or damaged)
Multimeter (to check battery voltage)
Basic tools for electronics projects
LED lights, switches, USB modules, or small motors (depending on project)
Safety gear: gloves and eye protection
