Introduction
Throughout your continued use of your speaker’s lifespan, you may notice it not lasting quite as long as it used to, overheating with minimal use, or just not working at all. This may indicate the need for a battery replacement. This guide will demonstrate the proper procedures for replacing your Anker Soundcore Boost A3145’s battery. It is important to note that your device should be fully powered off and unplugged before proceeding with the repair.
What you need

Insert a spudger between the base of the speaker and its body.

Along the seams of the base, begin prying at the hooks until you hear a “click”.

Once you get a slight lift, slowly glide the spudger throughout the base to unlatch all the hooks.
