Frequently Asked Questions

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

The best way is to check the Part Number (P/N) or Model Number on the original battery. For example, look for P/N: 533-000128. Matching the specific part number is key. Many speakers have different hardware revisions. This guarantees the connector and voltage will be fully compatible.

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

Often, yes. If the Voltage (V) meets the specs and fits in the speaker's battery compartment, a higher mAh rating means more playback time per charge.

Is it difficult to replace a Bluetooth speaker battery?

It varies by model. Some speakers have a simple battery door. Others need you to remove the outer mesh and unscrew the chassis. Check the repair guide for your model. Most replacements take just 10-20 minutes with basic tools.
