However, you don't have to replace the speaker to get it working like new again! All you need to do is reach for a replacement battery, which you can easily install under the housing of the device yourself. All you need is a screwdriver and a short instructional video run on YouTube.

Ideal fit Newell batteries are characterised by their exceptional build quality. The Newell replacement perfectly fits the Bose speakers of the designated model. The perfect reproduction of the shape of the original cell ensures the highest level of safety and trouble-free installation. Replacing the battery – good practices To remove the outer speaker cover, undermine it with a plastic or wooden spatula, taking care not to scratch the housing. When replacing the battery, you will also need a screwdriver. Use this to unscrew the unit. In many speaker models, a large number of screws need to be removed to reach the battery. If you find it difficult to dismantle a part, do not use force! First make sure that all fixings have been properly unscrewed or removed. If you feel resistance when removing the old battery from the speaker, proceed with caution! Do not jerk the cell or use excessive force. Remember that a swollen or damaged battery can be a real danger to you or the environment. If you have a model of loudspeaker where you have easy access to the back wall of the battery compartment after disassembly, it is a good idea to use double-sided adhesive tape. Tape one side of the tape to the wall of the loudspeaker, and attach the new battery with the other side. Note the polarity of the battery pack. Before you remove the old cell, take a look at how it was connected. Memory can be unreliable, so just in case, it's worth taking a photo! Check how the different coloured wires line up in order, then connect the new battery in the same way.
