2200mAh 088789, 088796, 088772 Battery Replacement w/PCB for Bose Soundlink Mini 2, Soundlink Mini II Bluetooth Speaker

I have two soundlink mini 2's. Both need batteries after 8 years of use. One wouldn't even power on and steady red flashing light when cord attached. Tried firmware update to wake it up but didn't work. Ordered 1 battery to see if it's worth replacing before investing in 2. The battery worked in the dead unit. Bit of a pain to disassemble speaker without damage. I made small tear in rubber around grill. Still had blinking red light when re-assembled with new battery. This was expected as this was the case in the YouTube battery replacement vids I watched. Connected speaker to PC and went to Bose Updater website. It said my speaker firmware was all up to date and didn't offer an upgrade option. You must force the update by pressing a, d, v, arrow up, arrow down and this will allow you to update. I just updated firmware to the same it was already running. Once the update completed, the speaker powered on and began charging the battery. Hopefully I get another 8 years out of it! Ordering another battery to replace the second one!

I have not installed this battery at this writing. I’m giving it a one star review because the special screw removal tool is not included with the battery. I’m tempted to return the battery but my speaker will not work with the present original. I purchased this product as the special tool was shown to be supplied. Fall advertising if you ask me. I will update this replacement battery after I remove and install the new battery.

Bose Original Charge board died so new one needed. Works fairly well. Have reset the unit using the Bose Updater Tool and now it charges. Time will tell if it lasts long for a battery replacement. Fit was an issue, there is a slight bulge down from being slightly wider than the original replacement.

Unless you are exceptional at soldering in tiny spaces, buy a new speaker. If you’re adventurous and willing to buy a new speaker after giving it a go, I say go for it. I got mine to work after a terrible soldering job but, like I said, it works and has been for a couple months now. UPDATE: After about six months, it died. Just buy a new speaker and save the money and time.

Excellent product, restored an old Bose Soundlink Mini 2. I had the latest firmware but had to force re-installation of it to get this pack to work. After that, an old and completely dead speaker was back in service.

Installed and it did not fix flashing red battery. There are also absolutely no instructions on how to perform battery swap. Why would you go through the extreme effort to plastic injection mold this enclosure, design pcb to fit that enclosure and buy/glue batteries for said enclosure.... Then do NOTHING further to show the customer how to install? Also the leads were not protected from shorting during shipping - i'm sure that's a major NO. If you measure with a multimeter the wires on two ends of wire bunch there's a 0 and ~7.2v wire. The boes speaker pcb has a + - marked on it where battery solders in. Tutorial video on amazon was for a different battery replacement, and it's a ripoff from youtube.

This worked! 100% problem solved.

If you don't have a temperature controlled soldering station and some experience soldering in tight spaces, this is not for you. You'd be better off just buying a new one, it's a tricky install even with the technique suggestion of cutting the wires off the old battery. However, once I managed to get it installed (which wasn't easy), it appears to be a solid battery. If I get a couple more years from the thing, I suppose it was worth it.
