7000mAh for JBL Charge 3 Battery GSP1029102A Replacement Charge3 3.7V

Worked fine, replacement was easy with YouTube guidance. Got rusty screws? Soak them in vinegar, then rinse with 90% alcohol, good as new. Easy peasy done in ten minutes. Speaker doesn’t crackle anymore on high volume.

This battery is perfect and feels like it lasts so much longer! I used it for two Jbls, 2and3.

Perfect fit. Works fine.

Replaced the battery in my daughter’s speaker. Now the house is jumping! The battery holds a charge and was easy to replace once you open the speaker. Watch a video.

Very easy to install, just takes little time.Great value for your money. Fit Exactly as the old one

My Charge 3 JBL Speaker has been great for 6 or 7 years but had started running down after a full charge in only a day or two. I decided to look at YouTube for instructions on how to replace the battery. Sure enough they are there. I ordered this from the YouTube link provided (in the comments with the video) and when the battery arrived, sat down and followed it step by step. I will add one thing. You should make sure you have a Phillips screwdriver with a proper tip. (#1 tip or even a #0 tip). This is next sharper than a #2 tip - which most people own. This battery comes with a phillips driver that you can make work but you will hate life after a few minutes. Just get a decent screwdriver not a tiny Fisher Price model that this comes with. Also, if you have someone who can video you removing the screws (go slow and make sure they can get a good shot of each screw location) then you may just manage to put them all back!! I was pretty careful and when all was said and done I had a new battery and everything in place and screwed down AND TWO EXTRA SCREWS!! This was installing a battery in my unit and no screws came with it - so obviously I missed two but there are MANY screws to make sure it is properly sealed and water proof. If you do what I recommend and document you will be fine. Also, the YouTube Video was of a Charge 3 that was not identical to what I was doing - so I could not review the video to see where I missed a couple of screws since it was different enough to not be a fix. It did show the important parts of how the heck to get into the unit and how to remove one of the end caps. Just go slow and steady and watch carefully to get it open without damaging the clips that must snap back together when you are done!! It works perfectly and I am still running two weeks later on the charge from the factory!! Problem solved!

My JBL Charge3 would run for about 5 min then all lights would turn red. Bought this battery, followed one of the sets of instructions on the internet, speaker works great.

Easy peasy, lemon breezy. The battery for JBL Charge 3 comes with a little metal spatula to lift plastic tabs and a screwdriver for the tiny screws. Unless you already have a small tipped screwdriver, this tool is very much needed.

Llego en tipo y muy bien empacada, hasta ahora funcionando bien

There are instruction videos on-line that show you how to replace the batter in a JBL Charge 3. This battery was a perfect fit and after installing it, it restored a great portable speaker. A little do-it-yourself is better than throwing out an otherwise fine product.

Working is so good

The service was great and the battery is working as expected

Battery worked great, but the package did not include the screwdriver or pry tool Edit: They sent a refund for missing parts, much appreciated.
