Product Overview

Revive your powerful JBL Boombox 1 with a next-generation upgrade — our seamless-compatible 7.4V 10000mAh lithium-ion replacement battery, engineered to dramatically extend playback time and restore peak performance to aging or degraded units.

Built using top-tier Grade A lithium-ion cells and reinforced with a multi-protection circuit board (PCB), this high-capacity battery ensures stable voltage delivery, efficient charging, and intelligent safeguards against over-current, over-voltage, short circuits, and thermal runaway.

The advanced BMS (Battery Management System) dynamically balances cell load and prolongs cycle life — rated for 800+ charge cycles — making it not just a repair solution, but a long-term investment in your speaker’s longevity.

With exact OEM dimensions, polarity alignment, and connector compatibility, installation is truly plug-and-play. No soldering, no modifications — simply open the rear panel of your JBL Boombox 1, remove the worn-out factory battery, and secure this upgraded unit in place. Within minutes, you’ll regain full functionality with significantly enhanced endurance, whether you're blasting bass at a rooftop party or setting the mood on a remote hiking trail.
