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 JBL Xtreme 1）

Easy to install and keeping me jamming

Worked great

Works great! Speaker now works again. :-)

Very poor quality. The wires from the battery into the clip are bare in places. Very disappointed. Will be returning it.

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 warranty period. 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.

Perfect replacement for the extreme 2 Also, very easy to install yourself. I would highly recommend this battery Instead of buying a new speaker or paying electronics store $100 for repairs Trust me buy this battery do it yourself.

Good buy!!

It fixed the problem, saving me money.

Hasta ahora no me ha decepcionado muy buena le quedó perfecto a la bocina y tiene mayor duración que la anterior alrededor de dos horas y media más que la original.
