Introduction
Go to step 1 ↓Is your hair straightener turning off just after a short time of turning it on? It might be the battery having defects. Due to overtime, batteries usually start to deteriorate, which may be caused by overuse of the device or just wearing out. Not allowing the battery to work as usual, and it loses its power to work to its full potential. If the battery in your Dyson Corrale HS03 has defects, it will need to be removed and replaced.
In this guide, we'll show you how to safely remove the battery in your Dyson Corrale HS03 hair straightener so you can replace it with a new 4-cell lithium-ion battery pack.
To make sure your Dyson Corrale needs a new battery, check out our Troubleshooting page, before beginning to make any repairs.
Before you begin, make sure the hair straightener is turned off, unplugged from the charger, and completely cooled if it was used recently.
Warning: Replacing the batteries requires spot welding, which involves specialized tools and experience. If you are not familiar with this process, review this article for guidance or seek help from someone experienced. Always follow proper safety precautions when working with batteries.
Lithium-ion batteries can be dangerous if handled improperly and may catch fire or explode.

Has anyone done this and it work? I’ve heard the new batteries have to be just right for the system to accept them
Laut meinem Research sind es 18650 Akkus mit 3,7V 2200mAh
Werde auch ein defektes Gerät besorgen und versuchen zu reparieren.
Hab die Akkus getauscht, hat alles geklappt. Aber jetzt blinkt die An/Aus Taste nur lurz ganz schnell und nichts passiert. Was nun?
@danielthom15017 It's nothing anymore, he became a brick
Akku ist getauscht jedoch zeigt er nun nur noch Flugmodus an,wie bekomm ich das weg, ja der Schalter für Flugmodus ist neu und richtig drin
