  10. Insert plastic spudger into battery brackets individually. "Wiggle" the bracket out of place
    • Insert plastic spudger into battery brackets individually. "Wiggle" the bracket out of place

    • Be careful to not bend bracket severely --brackets will need to fit back into place later.

  11. Use a soldering gun and apply heat to the battery contact tabs until solder is malleable.
    • Use a soldering gun and apply heat to the battery contact tabs until solder is malleable.

    • Once solder is malleable, carefully insert a plastic spudger beneath the tab and over the battery to pry battery away from the contact tab.

    • Use proper safety equipment when operating a soldering gun, as burns can occur. Gloves and eye protection recommended.

  12. Once contact tabs have been removed from the battery, the battery can now be removed by hand or by use of a plastic spudger.
    • Once contact tabs have been removed from the battery, the battery can now be removed by hand or by use of a plastic spudger.

    • Locate new battery and prepare for soldering in next step.

  13. Make sure battery is safely secured and re-solder the battery contact tab onto new battery.
    • Make sure battery is safely secured and re-solder the battery contact tab onto new battery.

    • Check that contact tab is re-soldered onto the original solder.

    • Once solder is dried and cool, toggle the power switch (not the power button) to check that the device is functional.

    • Make sure solder adequately covers the contact tab so the solder will not break in the future

    • Solder with caution. Use gloves and eye protection. Solder contains lead, work in a properly ventilated area.

For the Multigroom QG3380 (which I bought at Costco in Canada), there are some differences. Don’t remove the power button – not needed. Pry off the silver frame – very hard not to break some clips. It uses two 750 mAh AAA NiMH batteries (Suppo HSY-AAA0). I’ve ordered 900 mAh batteries with clips to replace these.
