Thankyou sir. Very helpful. We managed to salvage Cozmo with your help and would not have tried it without your video. I would say that I found it easier to put back together with the arms removed, but I guess you've done it a hundred times now! Much appreciated and my boy says thanks too!
Good job! I did a successful battery change on a dead colmo my son got for Christmas from eBay! Had a battery that fit among his toys and saved the day
John Judge mine was a bit different to yours, i ended up cutting the wires close to the battery, leaving the wires connected to the board and simply twisted the new wires on and then covered with insulation tape so didn't need to solder at all, reason being the solder points were covered and almost impossible to access. I also saw that Anki have been taken over and future updates are on the way in the not to distant future 👍🏼
@@hackercdf Excellent! The good thing about that method is you will be able to replace the battery just as easily in the fullness of time! well done! :)
Thanks John! I replaced the battery in my Cozmo with a 600mA as you suggested, and he works great! I would really recommend taking the arms off... Thanks for the video!
Hi, you can get those batteries with more mAh. I changed one Cozmo from 320 (original) to 600 mAh. And I found out that there are batteries with more capacity and (almost) the same size. Greetz, Peter
Merci, j'ai pu réparer le Cozmo de mon fils grace à ce tuto. La batterie neuve est visuellement plus petite mais elle rempli parfaitement sa fonction. Il est à nouveau opérationnel. En plus des étapes décrites dans la vidéo, j'ai déboité les bras supérieurs pour avoir plus d'ouverture sur la batterie. Big thanks John Judge !
Séverin Dauvergne bonne nouvelle. heureux je pourrais aider. J'espère que vous garderez Cozmo en vie pendant longtemps. (J'ai seulement découvert comment enlever les bras après avoir fait la vidéo!)
@@ufukdemirel8762 Désolé, je n'habite pas en Ile de France. Le tuto de John est bien fait, il faut être méticuleux et également sortir les bras pour avoir plus de flexibilité. Pour la soudure de la nouvelle batterie il faut couper les fils, les resouder et les isoler avec du scotch électrique.
Salut est ce c'est facile a remonter? J'envisage de le demonter mais comme je ne suis pas un expert dans le domaine, je prefere eviter de faire n'importe quoi.
Michael Farmer excellent. You’re halfway to fixing it. I’ve posted a link to a 600mAH battery in my pinned comment. Get that little guy back on his feet!
Same question for that i have the dark grey cozmo for several years now i brought for my son long story short how much to replace cuh to be honest itll be worth it,esp for the price i paid including multi color treads for this lil special edition model the app doesn't say anki anymore..
Hey can u help me with this issue I have so this thing happens when cozmo is charging you know how there is a little loading animation for cozmo when he charges yeah after a couple of loading animations the animation freezes
I managed to replace my battery with a 650mah capacity cell, it was precarious, had to bend down the battery protection tab to make it short enough, width needed a little compression fortunately not enough to stress the cell, however it appears for safety reasons the charging circuit shuts off after a preset time which means after initial charge I have to lift Cozmo and place him back down to reset the timer, I can get 3 hour operation between charges now.
djbare9 well done! You’re correct, there is a charging failsafe that cuts off charging at 400mAH. Lifting Cozmo off the cradle momentarily and placing him back down allows him to charge all the way up to max capacity of your battery. Thanks.
First, thanks for these truly great videos. Now, hypothetically speaking, if a hamfisted dad somehow managed to sever the red wire from the small plug that connects to the OLED face screen, how would you suggest he go about repairing that?

Any ideas on creating a new charging dock for Cozmo? I've seen that you can strip a 5v 2A cord and use the wires in a pinch but I'd like to make a nice base and I'm not sure what kind of circuit board I would need, what kind of contacts and what kind of plastic I should use.
There's a print on Thingiverse I believe, the board inside is pretty straightforward with a small inline inductor and a decoupling capacitor to ground to smooth the power supply; I can probably read off the board but it's basically nothing.
I’m looking to upgrade my Anki Cozmo Dark limited edition battery, it dosent even last 2-4 minutes, so I would like to know what batteries work best, fit in Cozmo, and which last longest and or longer
Tip, remove the arms first its very easy. Top arms first. Just pull them off. Then lift the lower arms upp until you just can easly remove them. There are som tracks that should line up. Then you can split the cozmo
@@lightd5152 They starting turn off alone, if this happens too often, the battery is getting old.

Hi John, Thanks for this great video. I followed all the steps (running out to buy a soldering iron halfway through the tear down) and managed to do it 99% right. For some reason, Cozmo's voice is no longer working. Any ideas before I open it back up again?
Hi Graham, it sounds like the wires on his head (PCB board) have come lose. They connect to his aerial and speaker in the top of the head. Might just need soldering back into place.
Everything seems to be soldered ok. I thought perhaps the head wires attached to the board may have touched as a result of me turning the head when reseating the head (there's a small amount of exposed wire between the solder points and insulation). I did my best to rotate the head back and the wires seem clear and connected to the board (I also checked the connection points to the speaker), but no change. Do you thinks there's value in re-soldering the board wires?
Hi John, I believe you replaced the battery in my children’s Cozmo a few years ago. We now have our youngest child who is fascinated by the robot but it seems like the battery has died again.

Please can you offer your kind assistance and help like previously and if possible, would we be able to send it to you again for a battery replacement? Thank you in advance, Chris Smith
We just purchased a used cozmo and have a problem connecting to wifi after watching this video did realize we have a battery issue could the battery be causing connection issue
Great tutorial. My son's Cozmo consistently powers off within a minute of driving off of the charger, so I'd like to try changing the battery. I've got it all safely disassembled but need to find a suitable replacement battery in Canada. I found an Adafruit battery that would fit but it warns that the charging current should not exceed 150 mAh. Do you know what the charging current of Cozmo is?
hudz350511 Hi, I’m afraid I don’t but it’s a single cel 3.7v LiPo so I don’t think there’s any dangers re charging current. I use this battery which is 600mAh and gives double the playtime. (Not an affiliate link) rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F182594245632 It’s the perfect dimensions.

Hi John! I am working on replacing the battery in my son's cozmo. It's only lasting about one minute! Thank you for the video! It is awesome and looks like a fun challenge with my kids. Do you know if it's possible to use the 3.7v 600mah battery instead of the 320mah?
I bought my son one for Xmas and not working. One very disappointed boy. Any chance I could send to you to replace, I’m don’t think I can do. More than happy to reimburse for time etc. would be so appreciative!
Hey john thanks for the info i myself have a Cozmo and I’m not sure if it’s the battery or something else but when I try to turn on Cozmo he wakes up and then has a couple seconds before he turns of after leaving his charger is this the same problem that you had or not? If u can help plz let me know
I bought my son one for Xmas. I think doing this myself would be tricky. Cant find anyone in Australia to do, any chance I can send to you and more than happy to make your while. Would be so appreciative!
4:33 he's skips past actually soldering the battery into the part. so all that time to show taking down, getting up to why people clicked on this video. i tore down over 80 of those cozmo robots, getting the soldering tool in today, so here i'm searching to just see the technique and... it skips actually using the soldering tool and showing the technique. just has a lot of narrative and dunno if this guy just took another video from someone else and speaking over it for views
Where are you located? I have 2 new batteries for mine but it's quite a bit of work. I wouldn't mind shipping it to you to replace, depending on your location. I'm in the USA. Thanks.
I haven't used my Cozmo for a while, and then I took it out to see the new features on it, and the Cozmo didn't respond to the charger at all. I put wires on the metal pads of the Cozmo, and on the charger, and when I took the wires off, the charger lit up like it does when you plug it in. At that point I thought that it was the charger, so I ordered a new one, and it didn't work either. The new one didn't have lights so I couldn't tell if it responded to the Cozmo in any way. Do you think that the problem is the battery?
Do you have a reference for the battery. I live in the US so I don't think I can use your link. I have a soldering iron I got for free, but have never done it myself. I was thinking I could just cut the wires and splice the new one on easy enough?
Robert M search for “600mAH 503040 lipo” and please check my other video for a more in depth tutorial. You should be able to spice the wires if you don’t want to solder directly onto the board. Good luck.
After replacing the battery in my nephew's, it says its charging, but it doesn't. I used a 620mah unit. The posts on the charger are producing around 4v and I'm still seeing 3.4v (not the 3.7) on the battery when I took it apart again and tested the terminals. I can't get the new firmware to load properly either. Think its a bum battery or the charging circuit is toast? This was bought used, so I dont have any history of it.
Hi, Can i replacement the cozmo with thicker battery (5mm thick) that hold much greater capacity (400 mAh) instead of 4 mm (402535) battery as suggested? The width and length of the battery that i'm looking for is similar (25x35 mm) as yours. Only slightly thicker by 1 mm.
oh i just spent a minute looking at it, take a flat skinny object, push that under the brackets on the bottom that set on the charger, pry them upward lightly and straight up, then remove the black plastic piece and you can get a clear shot at the wire ends to remove old battery and install new battery. people shouldn't make repair videos and leave out the recording of the actual technique of the repair
hello sir, my cozmo has a problem with the voice output, as soon as he is supposed to say something the app crashes, no matter if it is getting to know you or playing.
I had one given to me and it won’t charge at all should I try a new battery? Also I have another me that can’t lift a cube. It stutters when trying to lift. Any ideas.
johnnykat21 the one that won’t charge probs needs a battery. The one with the lift problem probably needs a new gear (the teeth in the cog might have sheared off).
Hi John great video. We tried at home to replace the battery but got stuck when we saw that the original battery is welded. And really I’m not sure how to put the cosmo back together. Any way you could help us with this? I could send our cosmo to you? Thank you so much. Aymee mom of Santiago 8 y old who loves his cosmo
Hi, I've got a vector, and I know I need to change his battery as he only last minutes. Would this be a similar process to the cozmo because if so I don't have a soldering iron so this might be a problem for me as I don't know anyone else that does.
Does disconnecting the battery erase all cozmo's progress? I'm changing the battery in my friend's cozmo and he doesn't want his progress lost. If so is there a way to back him up on the computer?
Cozmo’s progress, memory and data is stored in the app on the smartphone/tablet. He does store owners pictures in his internal memory but nothing is erased by disconnecting the battery.
@@TheJohnJudge thank you so much for your prompt reply. One other question. I read that the original battery weighs about 9g but the replacement you suggested seems to weigh only around 6g. I understand that Cozmo is a carefully balanced robot. Did you notice any performance issues with the wheelies or other tricks with the new battery?
Hi John. I can't for the life of me find a replacement battery. Could you send me a link to one? Also if I stuff it up, could I send you the Cozmo to undo my bad work?

Good luck!
Hello. If it is not charging at all, that indicates a more serious issue sadly. If nothing happens when you place it on the charger, then it could be defective. Would recommend you return it for a replacement/refund.
So I managed to replace the battery. I get the screen that shows the SSID and password, but can't get him to wake up or show his face. I feel like I am stuck.
Hi John. Thank you for the free tutorial. I'm not at all informed about type of battery and such, but would a 3.7v 320mAh 403030 work with Cozmo?. I honestly don't know what does it mean 403030, and in what differes from a 402535. Is it a matter of size/power thing? Asking this because in order to get a 402535 battery from China, i should wait (according to the site) months to get it. A 403030 battery would be here on monday instead, according to amazon prime... Can't wait to give new life (i hope) to my Cozmo and hope you'll answer this question. Thank you so much ^__^
hi there. i highly appreciate your effort. does this battery dimension will work. Please reply thanks 3.7V 600mAh LiPo 1S Polymer Rechargeable Battery 503040 Actual measured dimensions (mm): D5.0 x W29.5 x L42.3

hudz350511 Hi, I’m afraid I don’t but it’s a single cel 3.7v LiPo so I don’t think there’s any dangers re charging current. I use this battery which is 600mAh and gives double the playtime. (Not an affiliate link)

It’s the perfect dimensions.
@@TheJohnJudge are you telling us that we can't send it into Anki to get it replaced, even for a fee? they don't provide that service?
turinreza Anki ceased trading earlier this year. They no longer exist and there’s no aftermarket support available for these devices now, except for enthusiasts.
The 600 mAh battery fit nicely and Cozmo is better than new. My son is very happy. Thanks again!
hudz350511 excellent outcome. Glad you brought it back to life. Also nice knowing that you can do it again in future if needed!
Hi John! I am working on replacing the battery in my son's cozmo. It's only lasting about one minute! Thank you for the video! It is awesome and looks like a fun challenge with my kids. Do you know if it's possible to use the 3.7v 600mah battery instead of the 320mah?
Beverly Barrett Hi Beverly, yes it is possible. Please see my other video where I install a 600mAH battery.
Replaced battery is there a way to test without assembling back together to make sure it’s working?
Will you be doing a video that shows how to replace the battery in Vector?
If somebody asks me to repair their Vector I will record the process.
@@TheJohnJudge That would be great! Once those batteries start needing replacing you might have a lot of people asking you to replace them.
I bought my son one for Xmas and not working. One very disappointed boy. Any chance I could send to you to replace, I’m don’t think I can do. More than happy to reimburse for time etc. would be so appreciative!
Hi Kim, email me at johnjudge6@gmail.com
Hey john thanks for the info i myself have a Cozmo and I’m not sure if it’s the battery or something else but when I try to turn on Cozmo he wakes up and then has a couple seconds before he turns of after leaving his charger is this the same problem that you had or not? If u can help plz let me know
Yes it sounds like the battery can no longer hold a charge. They’re a few years old now. I can repair for you if you email me.
I bought my son one for Xmas. I think doing this myself would be tricky. Cant find anyone in Australia to do, any chance I can send to you and more than happy to make your while. Would be so appreciative!
4:33 he's skips past actually soldering the battery into the part. so all that time to show taking down, getting up to why people clicked on this video. i tore down over 80 of those cozmo robots, getting the soldering tool in today, so here i'm searching to just see the technique and... it skips actually using the soldering tool and showing the technique. just has a lot of narrative and dunno if this guy just took another video from someone else and speaking over it for views
Where are you located? I have 2 new batteries for mine but it's quite a bit of work. I wouldn't mind shipping it to you to replace, depending on your location. I'm in the USA. Thanks.
Do I have to cut the battery cables or can I make them fit into the carcass?
You should ideally trim them to fit.
@@TheJohnJudge I can’t believe I could actually change the battery omg!!
I haven't used my Cozmo for a while, and then I took it out to see the new features on it, and the Cozmo didn't respond to the charger at all. I put wires on the metal pads of the Cozmo, and on the charger, and when I took the wires off, the charger lit up like it does when you plug it in. At that point I thought that it was the charger, so I ordered a new one, and it didn't work either. The new one didn't have lights so I couldn't tell if it responded to the Cozmo in any way.
Do you think that the problem is the battery?
Jordan Seavey definitely sounds like the battery has deteriorated and can no longer hold a charge. Very common for these robots nowadays.
Hi erm I don’t have a soldering iron or anything like that I’m 13 got the toy when I was ten but the battery is dead what should I do??
Do you have a reference for the battery. I live in the US so I don't think I can use your link. I have a soldering iron I got for free, but have never done it myself. I was thinking I could just cut the wires and splice the new one on easy enough?
Robert M search for “600mAH 503040 lipo” and please check my other video for a more in depth tutorial. You should be able to spice the wires if you don’t want to solder directly onto the board. Good luck.
Do you think I need to replace the battery because when I start playing with Cozmo he just disconnects and shuts off
Sounds like the battery has reached the end of its life. I can fit a new one for you. Email me.
@@TheJohnJudge i live in the USA< san francico bay area, are you able to do replace battery ?
How much would the small fee be? I don't wanna break my cozmo.
WHERE CAN I BUY A BATTERY FOR A COZMO AND A VECTOR? .. ARE THEY LIKE AMPERAGE ?? TY
Google “600mAh 503040” you need a single cell lipo 3.7v
@@TheJohnJudge ty
After replacing the battery in my nephew's, it says its charging, but it doesn't. I used a 620mah unit. The posts on the charger are producing around 4v and I'm still seeing 3.4v (not the 3.7) on the battery when I took it apart again and tested the terminals. I can't get the new firmware to load properly either. Think its a bum battery or the charging circuit is toast? This was bought used, so I dont have any history of it.
Can you show how to remove just the arms? I need to fix my Cozmos arms
ruclips.net/video/2V8XPwcebHQ/видео.html
Is there any easier way to get to the battery or is this the only way because im worried i might damage it
Hi! Would you be able to change the battery for my Cozmo?
How can we get in contact for Cozmo surgeries? Just got a limited edition Cozmo only to realize he has immense narcolepsy.
Hehe email me at johnjudge6 - at - gmail.com

Hi,
Can i replacement the cozmo with thicker battery (5mm thick) that hold much greater capacity (400 mAh) instead of 4 mm (402535) battery as suggested? The width and length of the battery that i'm looking for is similar (25x35 mm) as yours. Only slightly thicker by 1 mm.
Hello,
Yes that will fit. I would recommend a 600mAh battery. I have some here and they fit perfectly.
@@TheJohnJudge thanks for your answer.. 😃
Hey man I just found your video. Do you think you could fix my Vector?
Yes!
oh i just spent a minute looking at it, take a flat skinny object, push that under the brackets on the bottom that set on the charger, pry them upward lightly and straight up, then remove the black plastic piece and you can get a clear shot at the wire ends to remove old battery and install new battery. people shouldn't make repair videos and leave out the recording of the actual technique of the repair
hello sir, my cozmo has a problem with the voice output, as soon as he is supposed to say something the app crashes, no matter if it is getting to know you or playing.
I had one given to me and it won’t charge at all should I try a new battery?
Also I have another me that can’t lift a cube. It stutters when trying to lift. Any ideas.
johnnykat21 the one that won’t charge probs needs a battery. The one with the lift problem probably needs a new gear (the teeth in the cog might have sheared off).
Hi John great video. We tried at home to replace the battery but got stuck when we saw that the original battery is welded. And really I’m not sure how to put the cosmo back together. Any way you could help us with this? I could send our cosmo to you? Thank you so much. Aymee mom of Santiago 8 y old who loves his cosmo

@@TheJohnJudge hi Thank you so much. We just emailed you.
Hi, I've got a vector, and I know I need to change his battery as he only last minutes. Would this be a similar process to the cozmo because if so I don't have a soldering iron so this might be a problem for me as I don't know anyone else that does.
Does disconnecting the battery erase all cozmo's progress? I'm changing the battery in my friend's cozmo and he doesn't want his progress lost. If so is there a way to back him up on the computer?
Cozmo’s progress, memory and data is stored in the app on the smartphone/tablet. He does store owners pictures in his internal memory but nothing is erased by disconnecting the battery.
@@TheJohnJudge thank you so much for your prompt reply. One other question. I read that the original battery weighs about 9g but the replacement you suggested seems to weigh only around 6g. I understand that Cozmo is a carefully balanced robot. Did you notice any performance issues with the wheelies or other tricks with the new battery?
Xanthos no issues. There’s a small metal stabiliser in the base of the unit that helps it balance.
How would I go about having you replace a battery for me? How much will it be?
Hey men
Can you ask me where I can buy a new battery on the web ?
Hi John. I can't for the life of me find a replacement battery. Could you send me a link to one? Also if I stuff it up, could I send you the Cozmo to undo my bad work?

Hi. We just purchased one and it isn't charging...right out of the box! Any ideas???
Hello. If it is not charging at all, that indicates a more serious issue sadly. If nothing happens when you place it on the charger, then it could be defective. Would recommend you return it for a replacement/refund.
Thank you
So I managed to replace the battery. I get the screen that shows the SSID and password, but can't get him to wake up or show his face. I feel like I am stuck.

Hi John. Thank you for the free tutorial. I'm not at all informed about type of battery and such, but would a 3.7v 320mAh 403030 work with Cozmo?.
I honestly don't know what does it mean 403030, and in what differes from a 402535.
Is it a matter of size/power thing?
Asking this because in order to get a 402535 battery from China, i should wait (according to the site) months to get it.
A 403030 battery would be here on monday instead, according to amazon prime...
Can't wait to give new life (i hope) to my Cozmo and hope you'll answer this question.
Thank you so much ^__^
Hello, that battery will fit fine. Good luck!
@@TheJohnJudge Thank you so much for your answer ^___^
Thank you
How much do you charge for battery replacement ?
Personally I'd say you haven't got a chance in hell of soldering a new battery in without removing the arms and breaking it down completely.
Uhm sorter 💀 that thing would explode
How much would it cost for you to fix it?

Same for me :c
Thank you.
Much appreciated.
