High-capacity Li-ion speaker battery

This 5200mAh lithium-ion replacement delivers 38.48Wh at 7.4V for the JBL Xtreme 2 speaker. A fully decoded chip ensures the battery communicates with the device exactly like the original pack. The unit weighs 220g and measures 138.50 x 40.00 x 21.00mm. It carries ISO9001, RoHS and CE certifications.

Simple swap with part-number verification

Installation consists of opening the speaker compartment, disconnecting the old pack and connecting the new one using the existing wiring. The critical step is confirming that your original battery carries the part number 2INR19 66-2 or SUN-INTE-103 before ordering. A mismatch will prevent the pack from fitting or communicating with the speaker electronics.

Check model and part number before ordering

Verify that your speaker is a JBL Xtreme 2, XTREME2BLKAM or XTREME2BLUAM and that the original battery label shows 2INR19 66-2 or SUN-INTE-103. If the model name or part number differs, this pack will not be compatible. Contact the supplier with photos if you are uncertain about the correct match.
