GSP1029102A 6000mAh Battery Compatible with Charge 3 Waterproof Bluetooth Speaker with Tools Battery Part NO Charge3

Completely renewed my JBL speaker. It wouldn’t hold a charge until I bought this battery and installed it (was very easy to do) now I’m able to listen to music at work for 6 hours a day for up to 4 days. Saved a ton of money not having to buy a new speaker. Great quality and fit perfectly. Even came with the tools necessary to do the job.

Order the battery to replace the old one in my speaker since I noticed it was not working as it used to. I would fully charge it and the speaker would turn off automatically after 30 minutes. I watched a few YouTube videos on how to replace the battery which was super helpful since no instructions come with the battery kit itself. Most of the process was easy except the part where you have to take the side cap off in order to disconnect the battery. It’s tricky and super tight on there. So have patience. The videos i watched showed people using guitar picks to help. I didn’t have that so i used one of the flat tools it came with and a small flat head screwdriver to compensate not having the picks and it worked. The battery seems to be working good so far. I will submit an update soon on my results after a few uses and charges.

Battery works great perfect fit inside the speaker. Keeps a charge just as good as factory

Worked perfectly, happy with price and quality

Bought this to replace the battery in my JBL Charge 3. I followed directions on how to disassemble the speaker from youtube and this battery fit like a charm. The tools that came with the battery were not grade A tools, but they helped with the disassembly. Once we powered on the speaker with the new battery, 4 LED charge lights were lit. Highly recommend!
