Bose Soundlink Micro Disassembly Battery Requires Soldering 

Those two rectangle black things are passive radiators. No magnets, or power. They run on air. Great teardown!

Thank you for posting this. Looks like you can buy batteries online and they’re a whole lot cheaper than replacing the unit. Was this close to just junking it, now I may try to replace the battery.

Thanks, we just cracked one open, using a knife and a hammer to break the seal all 3 sides, then a larger flat head screwdriver with a hammer to further wedge it open and pry it with the flathead. It worked easy and was fast, about 10 minutes. Sweet.

The latch on my rubber strap tore and I wanted to properly remove it. Looks like I'm better off just cutting it. Thank you for the vid!

Battery: 3.6volts 2950mah 11w/h lithium ion type 18650 cell. The 18650 is common to battery packs, 18mm in diameter by 65mm in length. Speaker: Those little speaker looking things are passive radiators. They move when the main driver moves. The enclosure is sealed and of a calculated volume. In this case this driver is designed from the ground up by Bose for this application (i read somewhere), it's not an existing part they pulled off the shelf. Battery upgrade considerations: First option, staying with 18650 (18mm wide by 65mm long) format and going from 2950 to 3500mah would add one hour playtime, at half volume. (6 hours playtime at 50% volume with the 2950mah. 2950/6 = 491.6mah/h~ 500mah/h) Second option: changing battery type from 18650 to 21700 (21mm wide and 70mm long) will increase the volume of the battery and therefore charge. The 21700 go up to 5000mah. At a discharge of 500mah/h at 50% volume this nets about 10 hours playtime. Both batteries are 3.7 volts. -Does the bigger cell fit? -Will the reduced enclosure volume affect the sound? -Can the same electronics already in place safely manage the charge/discharge of the battery? (i’ll say yes since the voltage remains the same and mah can already be increased without problem) Disclaimer, i’m not an electronics guy! I’ve just had too much caffeine+ google+ new toy :) Thank you for this video !!

Thanks for the video! Mine ended up getting some stinky stuff on it so I needed to get the cover off so I could get it all cleaned off.

these things should be easier to open for repairing or battery replacement. I've had a JBL Charge 3 which the battery got rather fat and died and i had a hard time getting opened up. It just doesn't look the same anymore. I mean I also have a Casio watch and it is so easy to open and replace the battery, and I'm talking about a 200m water resist watch. They could easily do this. It would be great for us and the environment because you'd only have to dispose a battery instead of the entire thing. Not to mention that I, at least in my case, love to repair things and get them to work again.

4:45 that’s a passive radiator it helps boost mid-high bass frequencies however doesn’t usually help deep bass.

Thanks for this, pulled my speaker out of a drawer the otherday, can't get it to charge! Will be taking it apart and trying a new battery soon

Mine isn't charging bc of the port! but good you show how to open it. Mahalo!

The 4.2V labelled on the battery is the charging voltage, written in Chinese.

In the process of opening it, is the speaker mistreated a lot? Do you recommend me to buy it?

Battery is just a 3.6v lithium ion, you just need one that's the same size or smaller (all Li-Ions are 3.6v). It looks like a 16650 size or 18650 size (16/18 is the diameter, 65mm or 55mm is the length). A $5 (new) lithium-ion battery.

oh that "speaker" with no wires connecting to it is a passive radiator! it just vibrates with the main speaker for a fuller sound

I try charging mine and it just gets a little hot. I’ve tried everything else on it from RU-vid. Nothing lights up. You think it’s the battery?

Mine has a damaged speaker, I connected an external speaker in parallel and it could be heard perfectly, the electronics and the battery are fine, but not the speaker. I can't find the component to buy and do the repair. Do you know of any page that sells the parts for this device?

This is harder than it looks. Good luck trying to completely seal these up again. Mine never sounded the Same.

Last video i commented yes it wont turn on. Even if i plug in my charger, the lights wont turn on as expected but no it has no power going. I even tried the charger if it was the problem even i used a new one so it would work but no power still.

Hi there,very good video, could you provide any link to buy those batteries please, That would be greatly appreciated. Thank You

Ayo so I got one and there might be some dust inside, I was thinking since its waterproof I can just literally run it under some water. Anything You'd recommend 😅

Can the battery be replaced by 18650 @3.7v?

Thank you for posting this. Now I can't assemble it back.

Hey, can you tell me the lifespan of this speaker? Thanks .

Dude, thanks for post this. Do you know if you the rubber/silicone case is "changeable"? Mine gets cigarette burns and seems horrible but the speaker works good.

Una pregunta, el pin de carga se me ha dañado es reparable? O necesito cambiar la tarjeta completa?

Hi ! It is possible to add a jack port ??? Thanks

when i pluged into charger my Bose soundlink mini detecting lights,one is on and next one off.what is the reason..? Please reply.

The paper wrap around the battery could be here to check for water damage?

My bose soundlink micro keeps on restarting whenever I try playing music ,can you help me find out what is the cause of the problem, thank you for the video

i don't have a pry tool but would a butter knife work lol

Is the waterproofing seal gone?

Has anyone actually replaced the battery. With what battery was it replaced with? Something that might be available in a link? I have bigger fish to fry than searching all day on the internet for a battery.

I guess I'm dropping another $ hundy on a new one....

heheh... im gonna take out the speaker

Hey dude, just some advice, cut your long nails please.
