Introduction

What you need

Step 1

Step 2

              Print a holder for the batteries
  • Print a holder for your new batteries on a 3D printer
  • I used a modified 3D model from ThingVerse
  • The original model is too big for the trimmer case. I modified the scale like following: X 97%, Y 84%; Z 95%
  • I stopped the printing at 60% of completion to keep the holder low enough to fit the trimmer case

Step 3

              Remove the old batteries
  • Remove the original dead batteries
  • I didn’t have a soldering iron, so I used a heated knife to slowly detach the batteries from the connectors. It worked okay

Step 4

              Attach the printed batteries holder
  • Place the 3D-printed battery case on the board so the connectors would go inside the case as you see on the pictures

  • Place the new batteries into the case. Pay attention to polarities
  • Before full assembly, you can test if the new batteries are charging

              Test
  • After the battery has fully charged the trimmer should work as new

Step 8

              Profit
  • Enjoy the proper working time of your refreshed trimmer

Enjoy the proper working time of your refreshed trimmer

My old batteries barely lasted one minute of shaving, and never held any charge. I didn’t test the full working time of the new batteries, but they allowed me to use the trimmer at least for 10 minutes.

Thanks to adding the battery holder next battery replacement would be way easier and faster.
