How to fix a Power tool Battery that Won't take charge

What happens here

Create several short jumper wires using red insulated wire and blue spade connectors. The video shows connecting three pairs of red wires, each approximately 4-6 inches long, with a blue spade connector crimped onto each end. These jumpers will be used to connect the terminals of the two Milwaukee M18 batteries. The creator uses a zip tie tool (DataShark) to bundle the wires, though this is later undone for individual connection.

Goal: Assemble jumper wires for battery connection.

Tools and materials

  • Blue Spade Connectors — To make secure connections to the battery terminals
  • DataShark Zip Tie Tool DataShark — Cutting zip ties cleanly and flush
  • Red Insulated Wire — To create the electrical connections between batteries
  • Wire Stripper/Crimper — Stripping wire insulation and crimping connectors
  • Zip Ties — Bundling the jumper wires for organization
