Sony SRS-XG300 Battery Replacement

Introduction

If your Sony SRS-XG300 (model XG300) is producing distorted audio or no audio, use this guide to replace the battery.

Before using this guide, review the troubleshooting pages to ensure the best solution is replacing the battery. A functional battery powers internal components, including woofers, tweeters, and passive radiators. As a result, the speaker plays music for extended periods wirelessly. A faulty battery can cause distorted audio or no audio at all.

A faulty battery can struggle to provide enough power to the speaker’s amplifier. At higher volumes, a faulty battery causes audio drops or complete audio failure. Additionally, the age of the battery can lower battery voltage. Battery voltage determines the usable volume. As battery voltage drops, sound will become weaker or distorted.

To check if your battery is swollen and to handle it properly, make sure to take proper precautions.
