How to Replace/Upgrade Li-ion Battery in any Bluetooth Headphones

[@theworddoner]

Thank you for sharing this. This is an environmental issue. We are throwing perfectly working devices into the landfill when they simply could be used again if we just replace the battery. I don't have all this equipment and expertise. I don't intend to do it myself. But if the battery in my headphones is not working as expected anymore, then I know that this is an option now. I'll just go to my local repair technician and ask them if they can do something like this.

[@ElectronicsComputers]

Cheap soldering irons can be picked up for peanuts these days, and basic soldering isn't really a very hard skill to learn. I'd recommend anyone who's even the remotest bit interested in trying to fix their own electronics to just pick one up (and a small roll of lead based flux core solder*) and giving it a go. The first time you use it to reconnect or replace a broken wire rather than taking a device to a repair centre, the iron and solder will have paid for itself. It's just one more simple to learn skill that will save you money, AND give you a real world sense of achievement (Something sadly lacking in many peoples modern way of life). You'd be amazed at how many quite expensive pieces of electronic equipment have soldered in batteries these days (Most laptops now haven't even got "User replaceable" battery packs), so being able to assemble and replace custom battery packs is going to become a more and more usefull skill to have. (* A law was passed in several counties a while ago outlawing the use of lead based solder in manufacturing or commercial repairs. Because of this, lead free solder was developed, but it's horrible to use and isn't particularly beginner friendly. Lead based is the only way to go for a learner)

[@tropezando]

​@@Reman1975Was that ROHS? In 2006-07, I worked in a factory that made printed circuit boards, but on the office end of things. My brothers worked in printing and in plating. I remember everyone who worked the HASL machine and the people who soldered components *despised* the lead-free product, and there were quite a few months of figuring out how to make boards come out decently with it.

[@Reman1975]

@@tropezando I've tried several different brands of lead free solder, and I've yet to find one that isn't truly awful stuff to use. Regardless of what additional fluxes I've tried, the stuff doesn't want to flow into joints like leaded stuff does. With practice you can get functional solder joints with lead free stuff, but it's significantly harder to get a professional looking result using it. I find myself lingering on every solder joint as I try to get it to "look right", but eventually the only criteria is "Is it holding the component securely? Is it conducting electric? Then it's soldered well enough !". If you're doing soldering work commercially, then UK law says you need to be using lead free solder, but for repairing/modifying/building your own stuff it's still perfectly legal to use leaded. It's easier to learn, and you can do the joints quicker with better results, so for hobby use, it's leaded every time for me now.

[@Mark-nw6lh]

So I can replace the 3.7v with 3x AAA rechargeable batteries?

[@Krzeszny95]

@@Mark-nw6lh in theory yes, as long as you never use the circuit to charge those batteries. You'd have to charge them separately. Charging them with a circuit that charges Li-Ion batteries from USB would blow them up (not just because of the voltage but because of the mismatched charging protocol). But how would you even connect AAA batteries to headphones???

[@mrmojo88888]

Great video. I just swapped the lithium battery in a set of BT300 headphones (Big Lots, $20). They wouldn't charge, the LED light wouldn't even turn on. After opening them up as you describe at :41, the rest was easy. The old battery was "puffy," so it was definitely dead. I'm not comfortable soldering on the circuit board, so I just cut and stripped the wires to solder them to the new battery wires. A little electrical tape, and tucked it all in. Back in service! The battery was HL602025 3.7V, (might also be PL602025 or LP602025). Amazon had a "Liter Energy Battery 3.7V Lipo Battery 300mAh Rechargeable Lithium ion Polymer Battery 702025 Lithium Polymer ion Battery", $9.99, next day delivery.

This video is brilliant. Straight to the point and clear. it gave me hope to fix the headphones I use for work. I opened the case to check the voltage on the battery and noticed this yellowish gum, it actually looks like dried glue, right where the battery was soldered to the PCB. I did some research and concluded it's not GS or RTV silicone adhesive because it's definitely yellow and slightly translucent, instead of white and opaque. What do you think it is, and how would you recommend trying to remove it without damaging the board? Thank you for your help.

[@ElectronicsComputers]

Could be thermal glue, silicone or who knows what Chinese could put inside. try carefully cut/scrape that glue with a plastic or metal tool.

[@The.Ramblr]

@@ElectronicsComputers thank you very much for taking your time to provide me a reply so quickly. I'll try scraping carefully with a plastic tool and see if I can remove most of it so I can resolder it.

Should've mentioned to use batteries with a built-in protection PCB (like the example ones you show have, where the wires come from). Bare Li-Ion or even Li-Po cells will overcharge and go boom. Otherwise good video though. Was looking exactly for something like this to send to a friend to show that this isn't rocket science and that they don't need to throw away their 70+euro BT headphones just because the battery committed sudoku (15mins runtime.. willing to bet it's bloated after 4 years)

I upgraded the battery in my Bluedio F2 headphones which I suspect was 400mah(it had no markings or a protection circuit) and factory spec 16h playback time to a larger 800mah battery from Cellevia. I have been using the headphones for 28h with no sign of them dying. More autonomy means less charge cycles which is really great. The old factory cell was swollen and smelled like bubblegum which suggests there was leakage going on due to the fact it had no overcharge protection and I regularly left them to charge overnight thinking there were cut-off circuits in place. So...cheap implementation from Bluedio for such a great pair of headphones. Thank you for the great information!

If you can't use one big battery, you can connect two batteries in parallel. In that case, the voltage will remain the same, but the capacity will double. It won't affect your headphones in any way except that the charging time will double, but at the same time, the working time will also increase.

Hi, great post. And I did the same thing on my SONY DR BT-50 earphone just recently.

All headphones during charging usually draw 500mA to 1 amp so even if you connect 2A charger it's not gonna speed up the process. If you install a higher capacity battery it will charge longer and vice versa. That's all the difference here.

Great video man, could you give me advise for battery of sodo MH3

[@ElectronicsComputers]

This battery ali.pub/4s9c6x will definitely work you just need to swap the wires with connector. If you want higher capacity battery then give me dimensions of the internal space for the battery in your headphones.

[@obidullahjamy6701]

I tried swapping the swallon battery from my working headphone (the only problem was low charge backup) with a same voltage lithiam battery. but the Bluetooth connects with buzz and no music comes out. also the PCB ends up real hot that I had to turn off the headphone. However the headphone works just fine with connected to wall socket and no warm up issue is faced this time.

[@care-o-sene]

could I just snip the cable coming from the old battery and install a plug for easy replacement in the future? and then add the other plug to the new battery. i'm not particularly confident on my ability to cleanly solder onto the board. so i could just crimp the connectors onto the wires already soldered to the board, and also add connectors to the wires on the new battery

[@ElectronicsComputers]

Sure, of course you can. Good idea by the way!

[@Mito505s]

So is it okay to change batteries? Won't the earbuds get overheated and get damaged?

[@ElectronicsComputers]

Of course it's OK. Why they should get overheated?

great video man ! do u know how to replace the battery for Bragi dash pro inear headphones ? i bought them in 2018 for 300 usd and now they are started to lose charge and die after just 2 hours :( What kind of battery does that headphone use.. size and type ? im not sure about that to be honest or where to find none fake replacement batteries ?

[@ElectronicsComputers]

Most likely you'll never find an original battery. Moreover all earbuds are not designed to be serviced. They are glued together and after you open them up they will look ugly. If you manage to open them carefully, you can send me the picture of that battery and I'll give you the links to that battery.

Those figures represent battery dimensions thickness, width, and length. For example 401730 means that the battery is 4mm thick, 17mm wide and 30mm long.

My Bluetooth headphones only turn on while charging . they are old heaphones of mine . Is it good to charge while using it ?

[@ElectronicsComputers]

If those were new headphones, then I wouldn't do that. But considering the fact that they are already faulty you can do whatever you want with them. Most likely you need to replace the battery to make them work properly.

[@EpicBunty]

Hi dude since u have the same headphones as me (Marshall major) i wanted to ask if u have faced the problem where they will rotate completely to the other side and get stuck! That kept happening to mine and now the wire is frayed and one side does not work! Do u know what can be done about that!!?

[@ElectronicsComputers]

If one of the speakers doesn't work, then try to connect the audio jack into another ear. If it start to work but another one stop working, then you have to replace the cable that goes from one side to another through the headphones band. It's not an easy process because it requires some soldering skills and you have to completely disassemble your headphones.

[@EpicBunty]

@@ElectronicsComputers thanks for the reply. yes it is that cable only which is damaged because it kept getting bent. I just ordered a soldering iron. I just hope soldering the breaking wire will work... I will disassemble and see. thanks :)

Hello Sir, Can I replace a the Li-ion battery of 3.7volts with a 4-volt 400mah Lead-acid battery in my headphones?

[@ElectronicsComputers]

No! The charge controller in your headphones that designed for charging Li-ion batteries can't charge lead-acid batteries. But it will work just for powering the headphones and you have to take the battery out and charge somewhere else.

The higher capacity larger the battery. So if you can fit it into your headphones then no problems.

would this work for a bluetooth speaker? I have an high quality minirig rated at 50hrs with a 11.1v 1150mah battery. I would like to put it in a square shaped box with a 11.1v 5,000mah battery

Of course it will same process. I guess, there will be at least 3 batteries connected in series.

[@thisistheway9064]

How are the headphones from aliexprress sound quality wise ? and do they block noise ?

[@ElectronicsComputers]

Those are cheap headphones they do the job but the quality of sound is far away from Marshall or something similar. They are very lightweight and don't push on your ears so they don't block any noises. My kid likes them though.

It's not gonna work. You need to find a battery with three wires. That third wire is a temperature sensor and the charge controller may not charge the battery without that sensor.
