Introduction
If the Sony WF-1000XM3 charging case battery can no longer hold a charge or if the earbuds themselves cannot be charged, it may need to be replaced. Use this guide to safely replace it.
Before using this guide, check to see if the charging port on the case or the charging pins inside the case need to be cleaned. A small amount of contact cleaner can get rid of any dust or debris. Otherwise, the problem may be internal like the battery, the charging port, or the charging pins.
What you need

Use plastic opening picks to release the locking mechanism that secures the plastic shell of the charging case to its internal components.

what kind of battery is in the case?
What is the battery model of the battery?
14500 3.7v, as seen in the battery label on Step 2
Has anyone had any success getting the case flush again? I've done cable management and the battery wires are out of the way and stuck down but the outer shell does not want to go back flush.
