The Tool Shed — Workshop Tools and Power Equipment
Drills, drivers, grinders, saws and nail guns all live or die by their batteries. When a pack stops holding its charge, the tool itself is usually still fine.
Most cordless tools share the same basic parts: lithium cells that store the power, a battery management board that protects them, and a charger that puts the power back in safely.
Learn how those parts work together, how to find out why a pack has stopped, and how to decide whether to rebuild it, replace it or recycle it.
