はじめに

In this guide, you will learn how to replace the battery in your Treblab HD77. Rechargeable batteries have a tendency to deteriorate over time as a result of the constant draining and charging of the battery. Every time you recharge a battery it loses a little bit of its capacity and eventually it lowers to a point where it either cannot perform the way the user needs or the battery may stop functioning all together. Replacing the battery will give the speaker a longer life off a full charge, and will provide better power delivery which will boost the speakers overall performance.

Note that this speaker is water resistant and as a result uses a water resistant adhesive in some areas which will have to be removed in certain areas in order to access the battery. To restore its water resistance, this adhesive will need to be manually reapplied before reassembling the speaker.
