Cameron Sino 3400mAh Replacement Battery for 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.

My 5 star review was mainly due to fitting and working great when installed. The soldering was a little tricky, but I managed. I did have to update the firmware from the Bose Updater link in order for it to work. Now, lets see how long it will last...

If you are trying to salvage your Bose Soundlink by buying this version of the battery that requires soldering in the new ribbon cable, save your money and don't bother. The battery connections are live, the circuit board grommets are tiny and nearly impossible to properly solder, and if you happen to contact anything else on this tiny circuit board, you are screwed.

I replaced the battery in my Bose Soundlink mini II due to a flashing red light. While this was a challenge to get the old board off and the new one on, I was bummed when this did not fix my problem immediately. I got onto the btu.bose.com site, followed the installation instructions the used the "hack" of typing "adv" and pushing the up then down Arrows on the computer and was able to update the speaker. After a few minutes it started working again. Not sure if it was the battery or the update, but the new battery definitely lasts longer than the 10 year old one I removed.

Worked great charges to 100% and lasts longer than original battery. I soldered the wires rather than taking off the circuit board. Made it much easier, didn’t have to take the speaker apart. I did have to force the firmware to reload, from the Bose web site. Used a Mac with the “adv” then arrow up followed by arrow down command. Works perfect.

Lots of reviews here. I had no issues taking it apart and soldering on the new wires to the board wires. I replaced the battery and it said it was at 60%. I had it on the charger for about four hours to get to 100%. Still 100% some five days later. So, very happy with this battery for the price and a fairly easy installation if you have some basic skills.

This battery needs to be soldered into bose unit by a professional.

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!

Perfecto

Venía bien empacada y con 70% de carga. La instalación no es rápida, requiere desarmar completamente la bocina para poder cambiar la batería, lo que requiere soldadura. Siguiendo un video en youtube se puede hacer si se cuenta con las herramientas y habilidades necesarias: Desarmadores torx, planos, cautin, malla o jeringa para limpiar soldadura. La bocina prende bien y carga la batería al conectar el cargador. La he usado apenas por unas horas. Si falla actualizaré esta nota. Pongo 4 estrellas porque no es original.

the battery seems good

I was excited to try and revive my Bose speaker. Disassembly was a bit concerning as you pry the speaker cover out. It distorts easily but likely goes back in without too much evidence it was removed. Once apart, the battery is easy enough to remove. You do need to fully disassemble the speaker if you are attempting to desolder the cable. I too was not confident in trying to solder the board. I too cut the cable one cable at a time to make sure I didn't short it by cutting through. Just in case, staggering the cuts. I was pleased that I got it soldered and shrink wrapped and ready for testing. Sadly, the battery would not take a charge. I used the volt meter and it was reading only a few volts. It wouldn't take a charge. I tried a few tricks such as applying some heat to hopefully give it enough juice to hit the cutoff threashold. Nope. Even more concerning was the DOA return policy. I thought Amazon had free returns, but in this case, the seller asked for the battery to be sent back at my expense prior to authorizing my refund. $15 to ship it back. The reseller/amazon refunded my money without proof I sent it in. I did include photos of it being shipped. In my opinion, the battery likely was sitting for a long time before getting to me, and lost it's charge and the Bose would not recognize it as within range for charging. Unfortunately, without a return refund policy, it seems this is a lottery to get a good battery. If there was a refund free return, it would be worth the risk. Otherwise, I would not risk it given the hassle to install it to find out it's dead. Check the voltage before you start disassembly in my uncertified opinion.

Considerar que debe soldarse, ósea desarmar, checar un buen tutorial y si o si es desoldar la pila original y posteriormente soldar la nueva, además según es de más amperes y pues no es mucha la diferencia, hasta el momento jala de manera correcta y pues se descarga igual que la original, solo que está noto que tarda más en cargar 🤷🏻‍♂️ de allí en fuera todo bien.
