This STARNOVO battery is a direct replacement for the JBL GO FF, JBL Go and JBLGOBLK models. It matches the original part number GSP072035 and delivers 100% compatibility with the factory cell. The lithium-ion polymer pack is certified to UL, CE, UN38.3 and RoHS standards. It is sold new and ready for immediate installation.

The blue Li-ion polymer unit measures 8.0 x 25.5 x 41.5 mm and weighs 12g, fitting the original battery cavity without modification. It carries a nominal voltage of 3.7V and a rated capacity of 800mAh for extended playback. The pack is rated for over 300 charge cycles and includes integrated protection circuitry. Connections are made via the existing solder tabs on the speaker board.

Verify model and solder access before ordering

Confirm your speaker uses the exact part number GSP072035, as other JBL GO revisions may use a different cell. Replacement requires opening the sealed enclosure and desoldering the original pack, so basic soldering tools and skill are necessary. The 180-day warranty covers defects in materials and workmanship only. Buyers needing a plug-in module or a higher-capacity upgrade should look elsewhere.
