Unstick circuit board from the battery

  • Find the junction between the electronic circuit and the earbud battery just below it.

  • Using an Opening Pick or a very thin plastic tool, very gently unstick the circuit board from the battery by inserting the Opening Pick between the circuit board and the battery.

  • The circuit board sticks directly to the negative battery terminal with adhesive.

  • Caution: There is a tiny metal contact under the circuit board that makes contact with the battery. Unstick the circuit board gently to avoid damaging this contact.

  • Do not use metal tools in this step as you may short-circuit the battery.

  • Use caution if you decide to heat internal components as the red/white structural plastic will readily deform at low temps.

  • Once the circuit board is unstuck from the battery, lift it up as shown on the third picture to have enough space to remove the battery.

从电池上取下电路板

找到电子电路和耳机电池之间的连接点，就在下方

使用翘片或很薄的塑料工具，将翘片插入电路板和电池之间，轻轻地将电路板从电池上取下。

电路板用粘合剂直接粘在电池负极上。

注意：电路板下有一个微小的金属触点与电池接触。请轻轻揭开电路板，以免损坏该触点。

在此步骤中，请勿使用金属工具，以免造成电池短路。

将电路板从电池上取下后，如第三张图片所示将其向上抬起，以便有足够的空间取下电池。
