Wireless & Bluetooth Speaker Batteries

When Should You Replace Your Bluetooth Speaker Battery?

Most wireless speaker batteries have a lifespan of 2 to 4 years (roughly 300-500 charge cycles). You should consider a replacement if you notice any of the following symptoms:

• Reduced Playtime: The speaker lasts significantly less time than when it was new.
• Sudden Power-Offs: The device shuts down abruptly, especially at higher volumes.
• Charging Issues: The speaker only works while plugged in, or the charging indicator flashes an error code.
• Physical Swelling: If the speaker case appears warped or the battery compartment is tight, the battery may be "swelling" and should be replaced immediately for safety.

Tips to Extend Your Speaker's Battery Life

To get the most out of your new battery, avoid leaving your speaker in extreme heat or direct sunlight, as high temperatures degrade lithium cells quickly. If you plan on storing your speaker for a long period, we recommend charging it to approximately 50-70% rather than leaving it completely empty or full. This helps maintain the chemical stability of the cells during downtime.
