Compatible JBL Speaker Battery

This replacement battery fits the JBL ROCK speaker using part number GSP552035 2S. It is built for owners who need a direct swap when the original pack no longer holds a charge. Buyers looking for a higher-capacity cell or a different voltage should check their device specifications first.

3.7 V Li-Polymer Power Characteristics

The lithium-polymer cell delivers 3.7 V and 620 mAh for 2.29 Wh of energy. Internal resistance stays low during typical playback, so the pack runs cool and does not add audible noise to the speaker. Self-discharge is minimal when the unit is stored between listening sessions.

Ready-to-Install Single Pack

One black battery measuring 36.20 x 20.55 x 5.20 mm arrives in the box with no extra cables or tools required. The OEM-compatible connector aligns with the speaker's existing header for a quick installation. No firmware update or calibration software is needed after fitting the cell.

Questions about this item

How do I install the DS-CS-JBR100SL battery into the JBL ROCK speaker and what step is often missed?

Open the speaker enclosure, disconnect the old pack, connect the new 3.7V 620mAh Li-Polymer unit matching the GSP552035 2S part number, then reseal the case; the step often missed is verifying the connector polarity before closing.

What maintenance or replacement will the DS-CS-JBR100SL battery need later?

Li-Polymer cells degrade with charge cycles; expect reduced runtime after several hundred cycles and plan to replace the pack when capacity drops below usable levels for the speaker.

What limit appears first during sustained high-volume playback with the DS-CS-JBR100SL battery?

The 2.29Wh capacity delivers limited energy; under continuous high drain the voltage will sag and the speaker will shut down once the pack reaches its low-voltage cutoff.
