In this video I take on a full rebuild of a DeWalt 12V cordless drill battery pack from start to finish.
The original cells were tired and no longer holding charge, so instead of throwing the pack away, I decided to give it a new lease on life by repacking it with fresh, high-quality cells.

I’ll walk you through the entire process step-by-step:
🔹 Opening the battery pack safely
🔹 Testing and removing the old cells
🔹 Preparing new cells for installation
🔹 Spot welding the nickel strips with my new welder
🔹 Reassembling the pack and testing the final result

This rebuild not only restores performance but also extends the life of the tool, saving money and reducing waste.
