rapthor10000mAh JBL Xtreme 1 Battery Replacement with DIY Tools Battery for Xtreme1 Compatible with GSP0931134 Replaceable Battery for JBL GSP0931134 Speaker with Repair Tools 8.4v 37.0Wh

Great and comes with everything you need, even instructions that are better than the ones on iFixit. It's cheap and fixed the battery life issues. No complaints. If you need this, this one works perfectly.

Easy to install , battery lasts a long time , price was good and fitment was good as well . My speaker works now .

Exactly as described. Installation wasn’t so bad. Only a lot of screws to get to the point.

Speaker wouldn't last more than 15 minutes without being plugged in. This easy replacement solved that issue and back to new status 👍

Battery was perfect fit and exuded quality. All tools and instructions were included. I was impressed at how it all worked to make battery replacement systematic and frustration free. Thank you Amazon!!!

My JBL Xtreme’s battery was petering out ond would only go an hour and a half with full charge before quitting. It was clear to me that the battery had significantly degraded. I like this speaker and wanted to keep it so I started looking for a quality battery to replace the original. There are many options but I landed on this one. The install took me over an hour. Many screws to remove and the instructions, although very helpful did not seem to be in correct order. You’ll have to use a bit of common sense. That said I got the new battery installed using the supplied tools and all is great. I’ve been playing my speaker for 5 hours and all the charge indicator lights are on. So far very pleased. I have no idea how long or how many charge/discharge cycles this rechargeable battery will last but if the results are less than stellar I will update this review. If you never hear from me again, it’s still 5 stars all the way.

Replaced my JBL Bluetooth speaker battery, extended life on full charge, recommend the battery

Bought in 2022 and having to replace again Would not Recommend
