Frequently Asked Questions

How do I identify the correct battery for my Bluetooth speaker?

The best approach is to find the Part Number (P/N) or Model Number on the original battery; for instance, look for P/N: 533-000128. It is important to match the exact part number since many speakers have different hardware revisions and this ensures that the connector and voltage will be fully compatible.

Can I upgrade to a higher capacity battery for more playtime?

That's true. As long as the voltage (V) is within specification and the battery fits into the speaker's battery compartment, a higher mAh rating will result in longer playback time per charge.

Is it difficult to replace a Bluetooth speaker battery?

It depends on the model; in some cases the speaker has a simple battery door, in others you have to take out the outer mesh and then unscrew the chassis. For your particular model, you should refer to the repair guide since most of the replacements can be carried out in just 10 to 20 minutes using basic tools.
