Got a dead DeWalt battery? Don’t throw it away just yet! In this video, I diagnose and repair three different DeWalt batteries, each with a unique fault. Watch step-by-step as I bring them back to life using practical fixes that anyone can try!

🔧 Battery #1 – Faulty PCB Replacement:
One battery had a damaged PCB (protection circuit board). Instead of tossing it, I salvaged a working PCB from a scrap battery and restored it!

🔋 Battery #2 – Broken Connection & Failed Cell:
A broken connection caused one of the cells to fail. I replaced the damaged cell and renewed the connection, bringing it back to full power.

⚡ Battery #3 – 2012 Model with Bad Cells & Low Voltage Bank:
This older DeWalt battery had two dead cells and a low-voltage bank. I swapped out the bad cells and used an iMax LiPro B6 Charger to recover the weak bank, restoring the battery’s capacity!
