Where can I found the battery AEC653055-2s Rating 7.4V

My JBL Flip battery has been dead for a few years now, and only holds about a 5min charge. I always kept it plugged in when using, so even now that the battery is toast, I don’t mind.

Mine is not working anymore and I suspect that the battery is not charging. I´ve checked the battery and its code is AEC653055-2Pwith rating 3,7V 2000 mAh. It has 3 cables: red, yellow and black. I´ve used a voltage meetering to check if there some charge coming from and it had 4,0 VDC. So, probably the problem related to my device is with the battery, because it´s not charging. Anyone else had this same issue?

Marcio Michel noted, "I´ve checked the battery and its code is AEC653055-2Pwith rating 3,7V 2000 mAh. It has 3 cables: red, yellow and black"

Interesting observation: I too have taken my JBL Flip apart to replace a battery that no longer holds a charge beyond 20 minutes. My battery is labeled AEC653055-2S with a rating of 7.4V 1000mAH The battery pack's back is stamped 3342 and 7.4Wh It has a three prong molex connecter with blue, red and black wires. I tested my battery and it yields a voltage of ~8.2 volts.

From a physical battery standpoint, it appears the same. The battery Marcio specified is wired in parallel while mine is in series (-2P vs. -2S) and the specifications match: two 3.7v 1000mAh li-ion cells wired in parallel yield 3.7v @ 2000mAh whereas wired in series it will yield 7.4v @ 1000mAh. I am assuming then that the JBL Flip's circuitry accommodates both voltages. I also noted the OEM charging cable/transformer JBL supplies with it has an output rated at 12.0V @ 1500mA.

George - Reply

Never the less, my search for a replacement battery continues. I have found identically labeled batteries with just two wire connectors, but not one with three (I am assuming the third cable is a thermistor to balance the charge between the two cells?)

Has anyone else found a suitable battery, or better yet, an upgraded one to last longer? The original battery's dimensions are 65*30*15mm

I can not find this battery anywhere. Any links? Or guidance please. Thank you.

Did you manage to find the batteries? I might be able to help. Got the JBL Flip to power back up after replacing With a 7.4v 1200mAH battery, they're not the exact ones for the JBL but should work just fine, if not better. Unfortunately not easily found. I have around 5 left so If interested just let me know on 07961576800.

In my case it turned out their was a problem with the board. Battery replacement provided power to switch on but still refused to work. On that note the battery issues could have been caused by faulty board or other way round. Hard to know for sure... some food for thought.

Obviously their's no saying how they will perform in the long run, however rest assured you will get power again if the battery is your issue.

Hope that helps

Hey Gizmo, would it be possible to buy one of the those JBL replacement batteries of you if they are still available?

itzrami -

I have obtained a larger Li-po battery designed for those little remote control helicopters. It's a 7.4v 1500mAh battery. It is only slightly wider and thicker than the original but it is considerably longer. I am weighing taking my dremel to the JBL housing to make the new battery fit. It would entail filing out the side battery holder "wings" (no problem). But more substantial- removing the center screw post, permanently reducing it to just 2 of 3 screws keeping it together. The molex connector and wiring was also different than OEM so I deconstructed the old battery and installed the OEM top board onto the new battery (takes a bit of skill with a soldering iron but no biggie since the OEM battery is already useless).

So I am at a bit of a decision point- commit to the housing change or continue looking for the appropriate battery and leave as is. Good thing this device was replaced with a Flip 3 and thus relegated to non-working status. Else I'm not sure I would even contemplate the modification.

Hi anybody, same problem with flip one battery, no more charging after two years using it ; disassembling using this nice page Thx a lot ; but battery is no longer available (i have been contacting JBL) ; i think it's possible to use another one, or to make one using battery cells (caution about fire/explosion with lipo) ; my old battery has two cells, one is 4,6 v the other one is 0,6v , and i have no voltage going out the battery management system : i think battery had a problem, and BMS is in protection mode because cells are no more balanced ; can someone confirm that his battery has equal charged cells (and perhaps less than 4,6v, i think it's too high) ; and can someone mesure voltage going out of the board for charging battery ? (at the 3 pin little molex for connecting battery) thanks a lot for helping

Excellent guide. Followed step by step and it worked great.

How many of you are having trouble finding the right battery for JBL FLIP??

I have a solution for that.

danish - Reply

I'm guessing most of us are!

Patrick Pearce -

Hello,

after an exhausting search and emailing JBL and reading all the posts conclusion is, there is no battery to buy. So I ordered a LiPo battery with same Voltage, (2 cells 3.7V ea) and same AH (2000mah combined). Its for those RC helicopters. Then as George posted above, I dissected the old battery, took the little board between the cells out, dissected the new battery and soldered the board between those new cells. (When I say dissect, of course, not the cells themselves.) The batteries are found on ebay for under $10.00

It takes some experience and talent with soldering small electronics. Not for beginners. And of course, use that experience and talent to safeguard from shortening any batteries out after removing shrink or plastic wrap. Makes sure to re-wrap with appropriate sticky tape. I used clear packaging tape. So far works great.

Could you post a link to the battery you used? I found this website, but I wouldn't know where to start, though it's got so many batteries on offer, I'd be surprised if it didn't have something suitable.

Patrick Pearce - Reply

what is that sticky black substance??

Gireesh Hegde - Reply

Dr Gomi's battery part works/fits...it was incredibly fiddly. It was only after putting it back together that I realised there was an easier way to do it. DO NOT do what I did! The new battery came with a different terminal connecter, so I removed it and replaced it with the one from the original battery. The pins you need to refit to the ends of the new batteries wires are tiny, so I kept getting crossed stray wires when relocating them into the terminal block. The easy solution, which I didn't do...just cut the wires on the old and new batteries one by one, splice the wires together and tape them up. It'll then take you 5 minutes to attach the old connector terminal to the new battery...instead of 2 hours. Hindsight is a wonderful thing. FYI - the sticky substance retains its stickiness after you remove the battery. It tends to stay in one piece and is highly malleable, so it's easy to squeeze the new battery into it securely. Think of it as super sticky blue-tack.

you wouldn't by chance know where to purchase the replacement battery. And by the way you did a excellent detailed review in how to disassemble this JBL Flip 2 wireless speaker.

warning do not purchase JBL wireless speakers, because they do not allow you to purchase the replacement rechargeable battery once the warranty has expired.

throwaline - Reply

This worked as replacement. Perfect fit. Available on Amazon:

FLOUREON 7.4V 1000mAh Lipo Battery Pack 2S 20C RC Battery with JST Plug (Grade A cells) for RC

Cut the two wire plug off of this and as Patrick above says splice the old battery plug onto the new battery wires. Sweet! Wrote a success story which is somewhere on this site which has more detail.

Hi David,all put back together

The power comes "on" it can be connected to via Bluetooth;but the sound is there,but really "chopped up" (not useable) when turning volume up and down! SAme via line in,and no "Sonic bleep" when holding down power buttons any suggestions would be appreciated! Cheers for the fab teardown...

Well all put back together(the little rubber feet should be pushed back into grill after it's all back together (and not try place them in whilst sliding the unit back into grill).

Hi Folks... thanks for a great guide. I undertook the fix using a battery found on ebay, here:

http://www.ebay.com/itm/400997007344?_tr...

Works well, plays on battery, but when I attempt to charge it, I get a flashing red light (instead of static red light) and I don't thing it's charging successfully. I suspect this might be because there is no battery management chip on the battery I bought. Do you think this is the reason, or are there other obvious reasons why it may not be working? Otherwise, I may undertake the soldering exercise detailed above and transfer the old battery management chip onto the new battery.

All help appreciated!

OK - I transplanted the battery management chip from the old battery to the new one, and hey Presto! It works!

JBL seems to want folks to simply dispose of this speaker when the battery wears out. That is insanely wasteful...almost like throwing away a car when the tires are worn. As a non techie, there's no way I would attempt this replacement...so, unless someone sets up shop to perform this as a paid service for, say thirty bucks....all of these JBL flips will end up in a landfill causing more pollution. Maybe someone in China can make a business of buying up old Flips and refurbishing them?

There really should be international laws against manufacturing these kinds of products in ways that don't allow for simple battery replacement...it's evil on many levels to design these as disposable items when they could last for many many years if handled well.

EcoLogical - Reply

Agreed.

After feeling proud of myself for finally replacing the battery in mine ( battery cost about $9) and maybe an hour's worth of actual repair time (I also spent dozens of hours searching for the right battery and even bought two that did not fit), I happened to find brand new JBL flips on sale at Sam's Club for $50 each!

So even if I wanted to fix yours for you, factor in cost of shipping both ways, cost of battery and my time, I'm not much better off making money delivering pizzas!

Wat is the battery part number or model number

cjwarren42civics - Reply

This is the one I finally ended up using.

http://www.ebay.com/itm/2S-7-4V-1000mAh-...

You will need to remove the cables and board from this new battery and transplant the battery management board from your old battery onto the new battery pack. It's a fairly simple process if you have a modicum of soldering skills. Just be sure not to heat the new battery pack too much and as well, be careful not to damage the old management board and cables when removing it from the old battery.
