Repair FAQs

What kind of battery does the JBL PartyBox 310 use?

The JBL PartyBox 310 typically uses a specific rechargeable lithium-ion battery pack. It is crucial to use a replacement that matches the original's voltage, capacity (mAh), and physical connector to ensure safety and proper function.

How long should the new battery last?

A new, high-quality replacement battery should restore the original playback time of up to 18 hours, depending on volume level and music content. Initial battery life may vary slightly.

My speaker still won't turn on after replacing the battery. What's next?

First, double-check that the new battery is connected correctly and securely. Ensure the speaker has been charging for at least an hour with the new battery. If it still doesn't power on, the issue may be with the charging port or the main board, which could require professional service.

How do I dispose of the old battery?

Do NOT throw lithium-ion batteries in the regular trash, as they can be a fire hazard. Take the old battery to a local electronics recycling center or a store that accepts used batteries for proper and safe disposal.
