9000mAh Replacement Battery Compatible for JBL Xtreme 2 Xtreme 3 Waterproof Bluetooth Speaker (Part No: GSP-2S2P-XT3A) 2025 Upgrade High Capacity 7.4V Battery with Repair Tools（NOT for Xtreme 1）

Installed this batter a few months ago! Its holding charge it charges and it has a long play time. Im very satisfied with this purchase

Awesome product works perfect just make sure that they’re right one ? Everything went so well.

Installation was very easy. The battery claimed to have more power than the OEM. It took quite a while to charge the first time. The speaker did power up, but run time is very short, even though it shows 5 bars charged. I have plugged it in several times to insure that it is fully charged. I will retrieve it to use in less than a week and even though it was charged before putting away, the battery bleeds down to 1 bar. It is obvious the cells are either old, weak or poorly manufactured. The reviews seemed fair so I thought i would give it a shot. I did not throw away my OEM pak. I think I will try and disassemble and rebuilt it. This battery won't even make it through the warrantyperiod. Avoid it and try something else.****updated******I received a new battery under warranty. I installed it and runtime has significantly improved. I would give these guys another chance. Changed 1 star rating to 4.

Even though the battery is good… the battery itself does not hold the same energy as long as the original… I find myself recharging this battery often

I installed the battery in my JBL Xtreme 3, and left it charging overnight. In the morning, only the first LED was still flashing, and as soon as I unplugged the USB-C charging cable, the speaker turned off. Either poor quality or defective.

Great Price

the replacement went OK. I had to google search to find a replacement guide video to watch but that was easy enough. Also removing the old battery actually broke the old battery -- so while everything appears to be working great with the new battery, I am also relying on it since I dont have the old one anymore. that said, so far so good. strong long battery life.

JBL Xtream 3 replacement battery after one year use. Very upsetting original battery only lasted a year. Found this replacement battery on amazon for $25. I am hoping this one lasts a bit longer since it is 9000mAh. The only issue with this one was the tools are cheaply made. Luckily, I had a similar tool to use and a better screw driver. I used YouTube for the easy instructions. It took me 15 minutes to replace.
