It has a big, full sound that can easily fill an outdoor space, and I was broken-hearted to find out that the company disbanded and quit supporting their products, so I decided to give this replacement battery a try.I am not electronics-oriented, and I was able to follow the directions and successfully complete the battery replacement, though I recommend also watching a YouTube video. The screwdriver they give you works fine, but I'd recommend using a butter knife instead of the plastic wedge tool they give you to pry the sides off. Be careful, though, you don't want to crack the sides - if you do, you'll probably never find a replacement part.A few things to note about installation:1) The first 3 screws you'll remove (underneath the rubber tabs on the bottom) are a different size than all of the other screws, so put them aside. The rest of the screws are all the same, which makes it pretty easy.2) Pay attention to how the shiny metal grounding brackets go in the bottom of the unit. The instructions tell you to take a picture. They are pretty delicate, and when I was removing the last screw, the bracket kind of sprung up and flicked the screw away, which I then had to spend a lot of time finding on the floor.3) Before removing the old battery, pay attention to how the wires are routed underneath the small electronic board and be sure to do it the same way when you put in the new battery. There are even little posts that help you route the wires.So far my speaker works great, charges normally, and the battery lasts a lot longer than the original one. If anything happens and the battery dies prematurely, I will certainly update my review accordingly, but for now I'm very satisfied with the purchase. ### ⭐⭐⭐⭐⭐ I Almost Threw Out My Jambox!!!!! *by B***N on January 8, 2024* I've had a Big Jambox for many years but the battery shorted and would no longer take a charge. It actually happened just a year after it was new. Very frustrating because Jawbone wouldn't communicate about it at all. Then they went out of business. I've searched the problem and read accounts of the horrors of trying to replace the battery with no success. I can't imagine why. This battery came with step-by-step instructions that were easy to understand and easy to follow. I did the whole thing while I watched television. It only took about 30 minutes. The battery came as a kit with everything needed. The battery is amazing! It is much higher capacity than the OEM battery and even seems to give the low end a punchier "kick", it seems. (.....Maybe my imagination). This was a terrific bargain and an excellent application. My Big Jambox works perfectly now. I'm so pleased with the whole purchase/install. Order with confidence!! ### ⭐⭐⭐⭐⭐ 7 mos in, still long lasting *by H***K on January 29, 2025* holds a long charge, holding up well after several months. If the photo doesn't freak you out, proceed! It's not too bad. ## Frequently Bought Together - Rapthor 3250mAh High Power Replacement Battery for Jawbone Big Jambox Wireless Bluetooth Speaker J2011-03-US Easy to Install - TAIFU AC DC Adapter Charger for Jawbone Big JAMBOX Wireless Bluetooth Speaker: Big JAMBOX J2011 J2011-51-CA J2011-03-US J2011-02-US J2011-01-US J2011-03-USPWR HDP40-145248W-1 HDP40145248W1 Power Plug - Jawbone Big JAMBOX Wireless Bluetooth Speaker - Graphite Hex - Retail Packaging --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/135971161-3250mah-high-power-replacement-battery-for-jawbone-big-jambox-wireless](https://www.desertcart.tn/products/135971161-3250mah-high-power-replacement-battery-for-jawbone-big-jambox-wireless) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-25*
