This is just what the doctor ordered to restore my Bose SoundLink (1st Gen) to fully portable use. I have more battery-life now, than when the speaker was brand-new, out of the box. I've been cranking it up, jamming to my tunes, nearly daily, at high volume with no problems. This battery is a super-value! This battery is a VERY easy replacement for the first generation SoundLink. Just peel up the soft rubber mat on the bottom of the speaker, undo 4 screws, pull out the old battery, drop the new battery in, redo the screws, and put the rubber mat back. One corner of the rubber mat is permanently attached, so be careful not to break it, but the mat will still "snap" into place even if you do break the attachment. All together, about 5 minutes. No soldering or anything. If you can turn a screw driver, you can replace your old, worn-out battery in your first generation SoundLink speaker.

So far so good! I bought a really nice Bose speaker many, many years ago, and had given up on it—until I found this battery. It was easy to install, easy to charge, and so far, it’s worked perfectly, even when left unplugged for long periods of time. So happy to have an amazing speaker back up and running.

Worked as described and was satisfactory. Installation was a breeze and the charging speed was about what I expected. Battery life is not great, but for the cost it was adequate.

I was pleased to know that could continue to enjoy my Bose speaker with a simple battery replacement. This one fits and works. Remains to be seen if it will provide comparable run time but that’s what chargers are for. I like the sustainable components and the easy purchase and on-time delivery.

Bose Soundlink Bluetooth model 404600 Working like lt should. The old battery needed charging about every 5-6 hours so I figured a new battery was in order. I keep the voulume on the speaker at 100% and adjust the volume through my iphone, ipod touch, ipad or any other of several mp3 players I have. You will need a 2.5mm hex wrench to remove the screws on the back cover and battery. the battery came with a small phillips screw driver which was useless in this case, in the screwdriver drawer with it. I have been playing music from my iphone for 2 hours now on the original factory charge and the recharge light has not come on. You do not need to worry about charging the lithium battery if it is only partially charged but is not recommended to leave it charging all the time. the only hassle I had was getting the back to come off, after removing the screws I used a spudger to help it along. slide the back toward the bottom of the speaker and then lift up.

I bought my Bose SoundLink Mini v1 way back in 2013 not long after they first came out. We don’t crank music all day every day on it, but we do use it most days at least some. It’s easy to use and has rich, full, room filling sound for such a small unit. In short, we love it. The SoundLink Mini’s original battery lasted until June 2026. After that, the original battery would no longer take a charge at all. Because the speaker was so old, I was reluctant to invest in a new battery to try to fix it. But given that a similar quality replacement speaker was going to be a couple hundred dollars or more, and the price of this replacement battery was only $27, I thought I would give it a shot. Hey if it didn’t work out, it’s Amazon: I’d just return it! Buying this replacement battery was a good decision, at least so far. Replacing the old battery was a super easy job, but it does require a Torx T8 driver tool which I had, but I’m pretty sure a lot of people don’t. Through several charge/use cycles since I installed it, the replacement battery is performing as I hoped it would. A full charge runs the speaker at low/moderate volume for several hours. But of course, your mileage will vary. Frank Sinatra and our other music are restored to their former glory.

Battery is good

The Good: I have no issues with the fit and finish of this battery. The install was easy. The battery charged and playback was as expected. The Bad: A year later, the speaker plays for only about an hour before the battery dies. This is rather disappointing.
