Replacement battery for JBL JR POP speaker

This Cameron & Co DS-CS-JRP728SL unit is a direct replacement for the original L0728-LF cell used in the JBL JR POP portable speaker. It restores power to the device when the factory battery no longer holds a useful charge. The pack is supplied new and matches the OEM form factor for a straightforward swap.

3.7 V 400 mAh lithium-polymer cell

The single specification that determines compatibility is the 3.7 V nominal voltage paired with a 400 mAh capacity, yielding 1.48 Wh of energy. The physical envelope measures 38.70 x 22.60 x 6.80 mm, so the battery fits the speaker’s internal cavity without modification. A different voltage or larger footprint would prevent correct installation.

Steady output during extended playback

Lithium-polymer chemistry delivers a consistent voltage curve across the discharge cycle, so the speaker maintains stable volume and Bluetooth connectivity through the full 1.48 Wh capacity. The cell is rated for 100 % OEM-compatible performance, meaning it sustains the load profile of audio amplification without the voltage sag seen in aged or mismatched packs.

Questions about this item

How long will the 1.48 Wh capacity run my JBL JR POP speaker in practice?

The 1.48 Wh rating matches the original L0728-LF cell, so runtime mirrors the factory battery when the speaker is used at typical volume levels.

Does the connector follow a standard JST or Molex pinout so I can verify polarity before fitting?

The pack uses the exact plug fitted to the JBL JR POP, matching the L0728-LF pin layout; polarity is therefore identical to the original battery.

Will the 38.70 x 22.60 x 6.80 mm dimensions fit the JR POP battery compartment without modification?

Yes, those dimensions correspond to the OEM L0728-LF footprint, so the cell seats in the JR POP cavity with no trimming or shimming required.
