Introduction

You will need a soldering iron, heat shrink tubing, insulating tape, cutter, string cutter, Phillips screwdriver and a new battery pack.

The battery pack consists of 10 1.2 volt NIMH cells.

I ordered the cells from www.subtel.de.

“Battery 12V, 1300mAh, NiMH for AEG Electrolux AG901, AG902, AG903, AG905 - 4055132304 replacement battery”

These have 1300 mAh like the original cells. Of course you can also take some with more power, which then increases the charging time until the vacuum cleaner is completely full again.

Step 1

              Opening the Housing
  • Remove all 5 screws on the back side of the housing

Step 2

              Open the Handle
  • The handle is hooked with 2 plastic lugs on each side. you have to unhook it with a slotted screwdriver or something similar. Then carefully pull off the cover. and clean everything inside first.

Step 3

              Solder in the battery cells
  • Unscrew the circuit board, the ones in the handle are simply preconfigured (4 cells). Took the wiring from the old cells and soldered them to the soldering fans of the new cells & insulated them with heat shrink tubing. You must pull the shrink tubing over the cable beforehand!
  • Glue the temperature sensor for thermal monitoring into the cells with insulating tape.

Step 4

              Solder in the motor battery cells
  • Separate pack of 6 cells into pack of 2 with cutter & separate soldering tab with side cutters. Cover the cut housing insulation with insulating tape. Solder cells, note polarity! Test and then reassemble. Pay attention to the cable routing, it is very tight to the touch. I wish you success!!!
