rapthor 3500mAh High Capacity Replacement Battery for Jawbone Big Jambox Wireless Bluetooth Speaker

Works Amazingly!
My new Rapthor 3500mAh battery arrived well packaged and undamaged. Included with the new battery was a T6 Torx driver, a small plastic prying tool, and a small instruction booklet. I read previous reviews before attempting to change the battery. Under the suggestion of several reviewers, I chose to use my own T6 Torx driver as a number of reviews indicated the T6 Torx driver included with the battery was of cheap quality and had a tendency to strip the heads of the screws. I used a Craftsman T6 Torx driver which worked perfectly! I tried using the small plastic prying tool that came with the battery, but like many other reviewers, I decided to use a butter knife or other sturdy, thin item as my prying tool.The instruction booklet is small and the print and pictures are very tiny, but I was able to make out the pictures and read all print. You may want to take pictures of the booklet information and magnify that information if you are having difficulty with the small type. Overall the instructions are well written and easy to follow. I highly suggest you read through the instructions at least a couple times before attempting to actually replace the battery. This will help you to fully understand each step of the replacement process. I also took pictures, prior to disassembly, of each step. This may come in handy during reassembly or if you happen to wonder where a particular piece belongs.The first step is to pry off the end caps of the speaker. This is where the prying tool comes in handy (or your butter knife or other small, flat tool). It does take a some force to “pop” off the caps. I loosened the cap by running my prying tool all the way around all 4 sides of the cap before using more force to actually “pop” off the cap. Once both side caps were off the speaker, you then have to remove the the Torx screws with the T6 Torx driver. The screws are tightly screwed in place, so don’t be surprised if you have to use some force to remove them. You will notice they are screwed into a plastic casing. The only issue I had with the screws and plastic casing was when I removed the screws holding the grounding plate in place. One of the plastic casings holding the grounding screws crumbled, but I attribute this to the age of my speaker (it is over 10 years old) and plastic has a tendency to become brittle with age. This will not affect the functioning of your speaker should you encounter the same problem. The rest of the disassembly went well. I suggest you have some needle nose pliers handy as removing the plastic power clip (the one that has the red and black wires) is a little tricky since the clip is positioned just below the level of the circuit board. The needle nose pliers made removal and replacement a breeze! Prior to removing the red and black wires attached to the plastic clip, make note of how the original red and black wires are positioned on the plastic (note how they are positioned around the plastic prongs). You want to be sure the wires are not “pinched” when you reassemble your speaker. I used double-sided sticky tape to hold my wires in place so they would not move during reassembly. I also used the double-sided sticky tape to hold my new battery in place (you will note that the old battery had sticky tape holding it in position). The tape will help keep your new battery in place while you are reassembling the case. Once the battery was replaced, I just reversed all the steps to reassemble the speaker. My new battery came 75% fully charged, so I was able to test it immediately. It worked GREAT! I let it fully charge and it has been working perfectly ever since. Prior to battery replacement, my speaker would not hold a charge….the old battery was completely dead. I could only run my speaker off the power cord. Now that I have my new battery in place, I have run my speaker for about 6 hours of continuous use and my battery level is still nearly fully charged! I HIGHLY recommend this battery!Packaging of Product Upon Arrival: EXCELLENT!Quality of product: EXCELLENT!Ease of Battery Replacement: GOOD (There is considerable disassembly and this may intimidate some individuals)Instructions: GOOD (The instruction booklet is small and the pictures and print may be difficult for some to clearly view)Overall, I am VERY satisfied with this product. My speaker is holding a charge like it did when it was new!RDM

Easy peasy
I loved my big Jam Box but alas the battery pooped out in it — it still worked if connected to power but could not be used remotely without AC — so off to YouTube, find a video on how to take it apart — not too difficult — just a lot of screws and three screws hidden under the rubber chassis pads — once you get to the battery and get the small circuit board out of the way just unplug and plug the new battery in — I added some double sided tape so the batter was secure — put the unit back together and it was off to the races working again — back to loving my Jam Box and being able to take it anywhere I want.

Battery is awesome.
My jam box stopped holding a charge so I figured it was the battery. I didn’t even think it was a possibility to replace the battery but researching it there was this option. Shipping, packing were great. The problem was removal of the screws. I stripped half of them and some I couldn’t remove at all which didn’t allow me to get to the point where I could remove the old battery by the clip. I ended up splicing the new battery wires to the old battery wires. Not ideal solution but it works. It was that or toss it. New jambox is $175-$200 so definitely worth the effort to replace. Works great now.

Easy
Great instructions, low cost, nice to have tools included, great alternative to replacement.
