18000mAh Replacement Battery for JBL Xtreme, Xtreme 1 (Part No:GSP0931134) Xtreme Speaker, 2025 Upgrade High Capacity 7.4V Rechargeable Battery with Repair Tools

This battery gave new lifeand functionality to my JBL Xtreme 1. It was a great value for the the money. It was easy to install

This replacement battery is great. And the switch was easy. I would have bought this years ago had I known how inexpensive, fast and easy it was. You dont have to stare at your JBL Extreem speaker with a dead battery any longer. Just click the link and buy the battery, you'll be listening to music again in 2 days and it will sound stronger than the original. I was impressed with the quality of the battery itself and comes nicely packaged with everything you need to make the switch. Not that complicated ated and you dont need to pay a shop. Just YouTube the video and follow. A 10 yr old could do it.

This worked perfectly and seems to last twice as long as the original battery. Charged up and ran just fine.

When the replacement speaker is 200 and you already have 100+ invested in the one you have... 20 bucks seems like a safe bet. Found this battery linked in a YT video on how to replace it. Ordered, followed along, replaced, tested! Haven't charged it yet and I've used it a dozen times at 15-20 min intervals, still going!

Fantastic battery. Longer play , working great . My speaker is like new again. The installation wasn’t too bad though it took me half hour as I was being careful . I followed instructions on YouTube . I recommend this battery .

Exact replacement. You’ll need a YouTube video to install. Great price and comes with tools.

Easy to replace. Cheap and im getting more play time from my speaker.

I bought one of these before, installed it, and it ran fine. After installing this one, however, it became apparent it was a dud. It just doesn't take the charge. Sad because I couldn't install it until after the return date.
