Replacement Battery for JBL PartyBox Club 120

This Cameron & Co replacement battery is built specifically for the JBL PartyBox Club 120 portable speaker. It restores portable operation when the original pack no longer holds a charge. The unit is supplied new and ready to install.

7.40V Output Matches Original Specification

The battery delivers a nominal 7.40V output, matching the voltage the speaker expects for stable amplifier performance. Using a pack with a different voltage would risk distortion or shutdown, so this figure is the decisive compatibility check.

4500mAh Capacity Provides Extended Playtime

A 4500mAh rating translates to 33.3Wh of stored energy, giving hours of additional runtime at moderate volume levels. At maximum output the speaker draws considerably more current, so the same capacity depletes faster and will require recharging sooner.
