3400mAh Replacement Battery for Bose Soundlink Mini 2, Bose 088789, 088796, 088772

The battery was an exact replacement for the original battery and worked well after installation. I took the recommendation of one other reviewer and ordered a pack of solder and seal connectors. This made the job very simple compared to having to cut strip and solder each individual wire while avoiding any short-circuits. Carefully cut the old battery out one wire at a time as close to the battery as is practical and do not let the wires touch each other. Once you pass that point the rest is easy. Strip the wires slip on the solder and seal connectors couple of minutes with a heat gun and you're good to go. Be careful routing the wires when reinstalling the battery, first time I put it in one of the wires was touching the passive diaphragm on the back of the speaker and cause the sound to distort. Had to pull the battery back out and route the wire away from that part of the speaker, second time was a charm.

I read other reviews and was worried about soldering. Saw another reviewer's idea to use connectors (as pictured). Using that idea, I used "solder & seal wire connectors" and a heat gun. It worked perfectly!! The other reviewer used AWG 22-18, but I went smaller. I used AWG 26-24 white (0.25-0.34 mm2) which gave a nice tight connection. Plugged in the charger after the new soldering connections cooled and the battery was at 70%. AGAIN, don't shy away because of soldering. It's worth it to try the "solder & seal connectors" which are very cheep and very easy to use!

The connections were protected by glue and the wires were thin. It was not charging but gave a one flash green light when plugged in. Reconnected my old battery (only lasted for 2 hours), works fine.

Need Welding but works, if les blinking in red, try to update firmware and got a new bose fater battery replacement

First of all, the new battery is working fine and I'm pleased to be able to extend the life of the BOSE.The installation challenge is significant, however, and I would recommend that the wiring bundle, on the new battery, be extended to assist in the problem. I would recommend instructions that explain that the original wire bundle be left in place (soldered to the circuit board) then each wire separated and then soldered to the new wiring. That was my final solution, and it is working fine.

The battery is a lot more difficult to change than it seems. It requires the entire unit to be taken apart. Look for one (if they have one) that is already attached to the circuit piece

Old battery didn’t charge and speaker was too good to toss. This gave it a new life. I just cut the wires and soldered the new battery into them in the same order. Used it for 6 hours first day after fully charging and it was still at 60%! So, yeah, its fantastic. Worth the purchase if you love your Bose. Dont toss it, FIX IT!

This was easy for me to install, granted I'm handy and good with a soldering iron. Removing the old battery I just cut its ribbon cable about a half-inch from the circuit board in the speaker. Before desoldering I then used an Xacto knife and slit the half-inch remainder of ribbon cable into individual wires. I then desoldered/removed each wire one at a time.Since the Bose speaker is cast from aluminum it's impossible to burn or melt it while using the soldering iron. I then used a desoldering bulb (actually a solder sucker) to clear the holes in the circuit board. Once that's done it's easy to insert the new ribbon cable wires into the holes and solder them in.Four screws later I placed on the charger for a few hours. My Bose speaker works perfectly and even has more operating time since this new battery has greater capacity.Here's the desoldering tool I used: https://www.amazon.com/Kissmi-Solder-Sucker-Desoldering-Removal/dp/B07Q4N6CY5/ref=sr_1_2_sspa?keywords=solder+sucker&qid=1565772574&refinements=p_85%3A2470955011&rnid=2470954011&rps=1&s=electronics&sr=1-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzTTZUTFUzNjE1WUVJJmVuY3J5cHRlZElkPUEwMDU3ODAzMlI1TTVHSzg5RzJLMSZlbmNyeXB0ZWRBZElkPUEwNDIxMzMxVFpKWjhFS0JHTExYJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==
