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.
Happy to help!
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)
@@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.
@@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.
I like your soldering iron stand. Great video!
Thanks!
One of the best youtube videos tech tutorials so far, and usually I dont say this. Really straitfoward. Excepcional.
Glad you liked it!
Excellent video, thank you for sharing. Those days are gone where you could get headphones with Triple AAA batteries, was easy to recharge and carry backup batteries or even buy them in corner shops!
Thank you for the comment!
So I can replace the 3.7v with 3x AAA rechargeable batteries?
@@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???
Good tutorial. UA-cam needs more like you.
nice.. easy to follow and not too long. thank you for taking the time to post this
Thank you for the comment! I'm happy to help.
Excellent video! Just to know this is possible and to watch someone do it is enough to embolden me. The links are greatly appreciated too.

i opened my tiny earbuds with battery issues up and saw the 3.7v 50mah 501015 battery found a replacement online but the red and black wire go deep into the case and i dont see a way to pull it out. is there any way you can connect these different red and black wires if you snip them in the middle.
hello my friend i have corsair virtuoso and baterry is dead!!is it the same with void to change the battery?and if yes what battery i must buy?
Very nice bro... thanks for the information
Thank you for the comment!
Thank you so much it very helpful
Very Good explain
Glad it was helpful!
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.
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.
@@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.
Hi, could you advice maybe also make a video how to dismantle Boltune BH010 over the ear phone? Since it is over the ear headphone, I guess i guess cannot just simply rotate it counterclockwise. Thanks!
Can my Kinivo BTH240 headphone cam also be replaced ? They say some Bluetooth headphone batteries cannot be replaced so . Mine is not charging when I plug into the charger the red light blinks and switches off .
You can replace the battery in all big headphones. Earbuds are questionable but yours are definitely repairable.
Great work.
Thank you!
Really useful video!!!!
Glad it was helpful!
Great video! My board is getting too hot after replacing the battery with a larger capacity one. The headphones also make a loud click noise after play/pause of a song. Could you help me please?
What's the model of your headphones and give me the link or markings of the battery that you've put into your headphones.
Hi. Is it possible to replace the speakers from one Bluetooth headphone to another as to upgrade one of them? As in I prefer the physics and comfortness of one but the sound of the other?
Only if you can find something very similar speakers because they all have different mounts and size
Worked for me. Thank you for the links!
You're welcome!
Thank you sir
Happy to help!
My audio is stuttering while playing audio...but if i plug the charger and again play, it is fine....is it my battery problem...should i change it??
With fully charged battery the same problem? Or the problem occurs immediately?
Can I use the batterys for my Skullcandy ANC?
Thanks bro!!
Any time
Thanks!
Welcome!
One question i watched a tutorial that people are installing more batteries i meant a headphone with two batteries do you think that affect the head in the future let me more or less how many voltage can support those types of headphones thanks
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.
This is very helpful and I hope I can replace the battery in my JBL JR 300BT headphones. I cracked open the left side and the battery only shows 'gsp0420300118102933616' ... no other info. Any thoughts on what that is?
If you give me the precise dimensions of your battery in millimeters and its photo then I'll help you to recognize that battery and show you where to buy.
Hey thanks for the video I need advice on the battery for marshall mid
You can upgrade your original 680mAh battery to 800mAh with the same dimensions battery: ali.pub/4hwh8l
You can only use batteries with THREE WIRES!
Thanks a lot

Nice. Just doing my House of Marley, Positive Vibration headset. Sick of using the backup cord, lol. I use Ali affiliate links too, so I made sure to go through one of yours. Thanks
Thank you for your support!
@@ElectronicsComputersis it okay to use 2 wired battery instead of 3 all the battery available in my country only have 2 wire
@scotthale7857 The third wire goes to the thermal sensor, and without its reading, the charge controller may not charge the battery. Go to Aliexpress. There's a whole bunch of different batteries.
Hi again. I have a quick question. As long as the new battery has the same voltage as the old one, i can go for it right even if it is double or triple the capacity? Is the bms built into the battery or the headphones? And will it be safe for charging/overcharging etc?
BMS is always on the headphones' PCB. You can use any battery capacity you want.
Great video, very clear. My Grind Skull Candy doesn't have a battery level indication. Is it possible to test the battery condition?
If the charging time time takes the same time as before but the battery doesn't last long then you need to replace the battery.
If I am replacing a battery with a yellow wire do I need to get a new one with a yellow wire too? And if I buy a battery with a battery connector at the end of wires could I take it off or do I need to buy a battery with no connector, just the wires? Thanks
If your battery has 3 wires you have to buy the same. That wire is a thermal sensor.
I love my headphones but battery last for maybe 1 hour and I was wondering if there is way to fix that and there is. Thanks a lot man!
Almost all wireless headphones have replaceable batteries. The links for most popular LI-ion batteries are in the description.
Hey, great video man!
I‘m looking to replace my battery in my Master&Dynamic Mw65 headphones, but I‘m not sure what a right replacement battery would be. On the battery it says 720mAh and „+4.2V“ which I‘m assuming is the charging voltage?
Usually these batteries all should be 3.7V, right?
The dimensions of the battery are 37mm x 32mm x 8mm. Additionally the battery has three cables attached to the mainboard, but most replacement batteries only have two cables (positive and negative) so I‘m not sure if these would fit..
Any suggestions are greatly appreciated! :)
Fully charged Li-ion battery reaches 4.2volts so ether 3.7V or 4.2 volts on the battery means exactly the same. If your battery has 3 wires then you need to find the same one. That third wire it a temperature sensor. Can your headphones fit 40mm X 30 mm X 8mm?
@@ElectronicsComputersis it ok to put only 2 wires withkut the thermals
Very nice!
Thanks!
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.
Great job on fixing your headphones! And thank you for the comment!
Thanks for the video!
I am a bit confused with the batteries... is it ok to use a "LiPo" battery?
I mean, the links you provided says "lithium polymer lipo li ion" but im confused with the Li Ion and LiPo...
Can i use the same charger or do i need a special charger for the "LiPo" battery?
My headphones didnt come with a charger, so i use the same as my phone, but the battery is the same as the one you install but mine is 500mah
also 1.85wh, should i search for one with this too?
Li-Ion and Li-Po batteries are absolutely interchangeability.
@@ElectronicsComputers you can use similar circuits but they do use different charge voltage, low voltage, and sometimes nominal voltage. Internally, lipo and li-ion batteries are completely different. In your video you said that these are "li-ion pouch cells" but they are actually lipos that have li-ion in the name to attract attention. just false advertising. if it were li-ion that size battery would be about 5-10x more mah than what you are using. Just clearing up some confusion.
I have a pair of turtle beach 600 generation 2 headset for the Xbox. They are relatively new and were released earlier this year. They have a 3.7 1000mah battery but I'd to open them up and replace the battery with a 3.7 2000mah battery. But the replacement battery has a pcb how do I know when I need to remove the pcb?
That PCB has a short protection there's no need to remove it. If your old battery has 3 wires then you need a battery with 3 wires too. The same refers for a 2-wires batteries.
@@ElectronicsComputers infinitely helpful thank you!!! :)
Great video, keep up the good work. Can you give me an advice on the battery of sodo mh3?
I need the internal dimensions of the free space and the model of your current battery and then I could give you the links for proper batteries. Usually there's always enough room to put a higher capacity battery. So if you send me some pics I'll help you.
@@ElectronicsComputers sorry man i can't really open it or take a picture, all i know is it has a Li-Ion battery. But thanks for taking the time and replying, appreciate it!
Excellent video. What soldering iron do you use, as I don’t have one. Clearly it has to be a fine tip. Thanks again - I was just going to thro them ( MPOW) away.
The links in the description.
Were you able to replace your battery after?
Great video. The battery I removed from my headset isn't labeled with any voltages. Should I assume it's 3.7 volts? It does have a tiny circuit board fixed to the top where the red / black wires exit. Thanks!
Yes, they are all 3.7 volt batteries. I can identify the battery if you give me the precise size in mm.
@@ElectronicsComputers... It looks like a 403040 3.7v 450 mAh flat battery. It's approx 40mm, 30mm, 4mm. I may go with a higher capacity as long as it's all apart anyway :)
@@SG-cn4id you're right! I usually buy batteries here: ali.pub/4knlas
If you have plenty of room you can use higher capacity battery.
@@ElectronicsComputers I wish I could trust AliExpress, I'll pick one up from an electronics supplier in town here. They have all kinds, thank you for the update...
Great video man, could you give me advise for battery of sodo MH3
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.
I have a Sennheiser Urbanite I bought used. Do you have any idea what the battery life should be for these headphones? 2 years? More?
If you use them almost everyday the battery will last for about 2 years.
Amazing 😊
Thanks 😄
I have a question. What happens if I inhaled some breaths of the orange gray battery. Is it dangerous? I think I took in around 3 sniffs of it
You'll be fine don't worry about it. It's not gonna affect your health.
GOOD JOB
Thanks!
I could really use your help replacing the battery in one of my tws wireless W2 freedom Bluetooth earpods. My ear bud can turn on but no longer charges because half of the battery burnet out
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 assume you meant seppuku 😂 "committing sudoku" like your battery off solving numbers puzzles 😂
@@trixtonx whoosh... that joke went right over your head
@@Knaeckebrotsaege eh, I just didn't realize it was an internet meme to deliberately misuse the phrase... given the amount of idiocy on the web, sarcasm detection is a real hit or miss kinda thing
How would you recommend attaching the wires to the board without a soldering device?
Soldering iron will cost you 5$. There's no way to do that if there's no a battery connector.

How does the AKG N60NC open? It does not twist clockwise or counter-clockwise. Thank you.
There's no need to twist anything. Simply grab the edge of the earpad on the side where it is attached to the speaker cover and gently pull. Work your way around until it is completely unfastened from the cover. Once done, you'll see four screws; remove them, and you'll get access to the battery and PCB.
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.
Hi, great post. And I did the same thing on my SONY DR BT-50 earphone just recently. However, I am not quite sure on the part about voltage charger not concerned with mAh of the battery chosen for replacement.
If mAh is irrelevant and only the nominal 3.7-V charging input matters (including its size, of course), then I was wasting my time seeking high and low for the replacement the same as the original one. Any clarifications are greatly appreciated. BTW, the my chosen replacement with the same mAh as the original SONY one ain't cheap.... 😫
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.
@@ElectronicsComputers
Thanks a lot for the response, appreciate it.
But how about the higher discharged current from this more powerful battery replacement? Wouldn't the extra current cause any damage to the circuit? For example, if it is replaced from 3.7V, 750mAh to 3.7V, 2,000mAh. Thanks.

Very nice soldering job. The joints should be reliable as a result of your attention to detail.

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

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.
@@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 :)

You’re welcome 😊
My Bluetooth headphones only turn on while charging . they are old heaphones of mine . Is it good to charge while using it ?
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.
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.
How are the headphones from aliexprress sound quality wise ? and do they block noise ?
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.
@@ElectronicsComputers awesome thanks for the answer. I have a wireless vmoda crosfade that finally gave out on me battery wise. I bought some batteries per ur recommendation and i will be working on it while following your instructions. I bought the syrinringe thing too. Never knew about them but they look coveniant and easier to use
100% a useful video but sadly i dont have the calm or equipment to do this. it would be really great if tech companies made it user friendly to swap out headset batteries so consumers wouldnt have to perform an operation on their headphones.
Companies want us to buy new stuff and they do everything in their power (for example like Apple) to make the repair impossible.
Thank you good information. Questions sir, 1. How to find the polarities of the existing battery and polarities of the battery being replaced. 2. Where can I find the tools can you provide the list of tools needed?
Red wire is positive and black is negative. Also, there's always polarity marking on the battery. To replace the battery in most cases you'll need a screwdriver and soldering iron.

So is it okay to change batteries? Won't the earbuds get overheated and get damaged?
Of course it's OK. Why they should get overheated?
i have done it with my jbl headset but it is has same issue as before. charging led goes off few seconds after put to charge and not holding charge .
Do you have a multimeter?
@@ElectronicsComputers nope
How long did it take to get your battery’s deliverd?
About 2 weeks.
Thank you for the video tips. I was gonna use flat head screwdriver to pop up my headphone cover but I see in this video the cover is not hard to be open so I use a plastic card instead and yes it's works perfectly so I got no scratch at all on my headphones.
Good job!
Hello Sir, Can I replace a the Li-ion battery of 3.7volts with a 4-volt 400mah Lead-acid battery in my headphones?
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.
If the headphones board require 3 wires battery and there is 2 wires battery available then what should wo do?
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.
what a guy!
How long do these aftermarket batteries last in terms of recharge cycles, before they die? If an OEM battery will give you around 2 years before they lose their ability to hold a charge, what is the life expectancy of these cheap cells? I'm faced with this situation where my headphone battery is nearing the end of it's service life and needs to be replaced. But I don't want to have to do this step every two months.
Speaking from my experience they usually last for about a year.
@@ElectronicsComputers Thanks! 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! We should not have to throw away beautiful electronics because of bad commercial practices. Batteries should always be replaceable.

I change the battery from a original very small battery to a 18650 li-ion battery 2000mah, but the battery dont charge in normal way, can you explain? i do not found the answer in the internet, thanks
the previous battery had 3 or 2 wires? 18650 is a regular battery or it has microUSB port or something?
@@ElectronicsComputers The previous battery is a normal 3.7v Li-Ion battery but small, had a 2 wires, 18650 is a regular battery removed from a emergency light, i think the bluetooth device had a protection system specific to the small battery, i dont now
@@iorramgx2 It should work anyways. Maybe it just takes too much time to charge it?!
@@ElectronicsComputers I left it charging for 24 hours and it didn't exceed 61%, anyway I made an external charger for 18650 and this time the charging was complete, thanks for your attention
@@iorramgx2 61% are about at same level as previous battery 3.7v, and new battery are 4.2v?
If so , then "charge circuit" will charge new battery only to 3.7v not till your "new battery" 4.2v level which means you will get your 61% not full 100%.
At least that what I "guess".
Hello! Where can I buy the battery for Jabra Talk 30 please, thanks a lot!
What's the battery specs? Do you have a pic?
@@ElectronicsComputers Yes, how can I sent the pic to you please?
Can I instead use a 3x 1.2v AAA Batteries in series?
No, if internal charge controller was made for Li-ion batteries.
do i need to use a lipo with a protection circuit?
In 99% they all come with protection. So, yes.
@@ElectronicsComputers i have some small 2S 350mah lipo packs without any protection circuit. was thinking of splitting one and hooking them up in parallel but probably best not to.
Nice..
Can i use Bluetooth battery to the rc toys? I dont understand what's mean of battery serial number like 40xxx 50xx etc.. Can you explain?
Thanks
Those figures represent battery dimensions thickness, width, and length. For example 401730 means that the battery is 4mm thick, 17mm wide and 30mm long.
Oh i see 🙂
But will it be ok if i replace a battery for examples an rc toys using battery with number 60xx with baterai with number 40xx?
@@my.name.is.y You can use any 3.7V Li-ion battery that you can fit inside of your device.
Thank you very much 👍🏻
I'll try...
Sir plz reply
Sir have boat Rockerz 255f pro headphones and it has 3.7v 110 mah battery
What if I change battery mah to 250 mah it'll damage pcb board??
You can use any battery capacity you can physically fit into your headphones. It can't damage your headphones you can use any Li-ion 3.7-4.2V battery.
@@ElectronicsComputers thanks for reply sir
Perhaps my headphone is not included in the "any". It took me dozen of hidden screws to open it.
w8, where is marshall's battery replacement?
My bluetooth headphones have 3 wires to the battery. I looked online and found out the 3rd wire is RTC. I can only find batteries with + and -, and without the RTC. IS it ok to not have an RTC in it?
You need a battery with three wires otherwise it won't charge. Give me the model of your battery or its dimensions and capacity and I'll give you the link.
@@ElectronicsComputers its 3.8v 630mah.
model 792200-0010
the 3 wires from the actual headphones feed into a pcb with a few small components on it and then on the other side of the pcb it has the + and - of the battery soldered in so if i cant get a 3 wire batter i can just unsolder the current battery from the pcb and solder the new battery onto it
it is quite small 46mm long 31mm wide and only about 4mm high. there is room for a larger battery length wise but not width wise but i may be able to modify some things inside to fit a larger one if needed
i already ordered a 2 wire one for $10 but if there is a 3 wire one i might buy that
@@Sam-fp8zm This one will do the job: alii.pub/6gzxy3
@@ElectronicsComputers
thanks. i found the single item listing.
i will try the method i said with the battery i already ordered and if it doesnt work i will buy the one you said. thanks again.
i have a 3.7 v and 250mah battery but i want to replace that with a 3.7v 800mah is it compatible????
If the size allows you to fit such a battery then it's possible. The links for the different batteries are in the description.
Thank you so much for the advice.
