This Cameron Sino battery matches the original JBL Boombox 2 specifications with a 10400mAh capacity at 7.4 volts. It uses the part numbers SUN-INTE-213 and SUN-INTE-268 for exact fitment. The lithium-ion cell composition delivers 76.96Wh of energy. A fully decoded chip ensures the speaker recognises the pack as an original component.

The pack measures 135.00 x 75.00 x 22.20 mm and weighs 378.0 g, matching the factory battery footprint. No modifications to the speaker chassis are required. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. Installation videos are widely available online for straightforward user replacement.

Restores runtime lost to worn cells

Questions about this item

How long will the 10400mAh capacity last before it needs recharging during continuous playback?

Runtime depends on the speaker volume level and audio content; the 10400mAh / 76.96Wh rating matches the original JBL Boombox 2 specification.

Does the lithium-ion pack run hot or make noise when the speaker plays all day?

The battery is a passive component with no fan or moving parts; it produces no audible noise and normal operating warmth is managed by the speaker's own thermal design.

What must I already own to install this 135.00 x 75.00 x 22.20mm replacement pack?

You need a JBL Boombox 2 speaker (part numbers SUN-INTE-213 or SUN-INTE-268) and basic tools to open the battery compartment.
