JBL Boombox Battery Replacement

This lithium-polymer battery is built as a direct replacement for the JBL Boombox portable speaker. It restores original run-time when the factory pack no longer holds a charge. Buyers who need a different voltage or connector will not find a match here.

7.4V 10000mAh Capacity Limits

The pack delivers 7.4 volts and 10000 milliampere-hours for 74.00 watt-hours of energy. That capacity defines the maximum playtime the speaker can achieve on a single charge. Users who expect longer run-time than the original specification cannot gain it from this cell.

Upgrades Worn-Out Original Packs

The battery replaces an exhausted GSP0931134 01 unit inside the same Boombox enclosure. The jump is worth it when the speaker cuts out early or fails to power on despite a full charge cycle. It does not add features or increase output beyond the factory design.
