Trying to REVIVE Faulty Nintendo Switch Batteries

  • Published on May 27, 2019
  • Hi, in this video I try and use a TP4056 to revive faulty Nintendo Switch batteries. I have 3 batteries which are not recognised when they're in the Nintendo Switch. They do not allow the Switch to charge them.
    Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
    I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
    Many thanks, Vince.

    I have one Samsung phone battery, the poly fuse gone bad, it does have voltage across the pcb board terminal, but when it have a light load like draw 100ma, it will break connection. End up I just short the fuse away and it worked.

    that tp4056 board can charge up a cell directly
    you just have to connect + and minus over
    the board tha's got water damage is a battery protection board that prevents nasty things going into the battery and you can in fact get them off eBay
    there's however a string possibility that: a) don't fit b) haven't got the proper protocol the switch requires to sense a good battery
    keey doing these investigatative videos, they's fun to watch, they remind me dois this same thing 20 years ago!

    Why not try to get a female connector for the battery?
    then you can solder it to the two wires from the charging circuit.
    Worst case you can try to desolder it from a faulty switch.

    31:40 The chip is a QFN type, so you don't really need hot air. Just use some flux, and drag your soldering iron over the pads, but the difficult part is to disconnect the battery. Idk if it's spot welded on, or soldered, but looks like it's welded on

    One of the tricks to reviving batteries is pluging it in and out for about 20-30 times with one to two second charging cycles. I revived so many discharged GBA SP batteries that way. Crude, but efficient. Only thing to note is that you need to disconnect the charging wires, not the charger itself (the remaining charge in capacitors mess up the procedure), if you do this often enough it's useful to just hook up a power switch to the wires. You can see that charging light lasting ever so slightly longer each time and then it just stays on and charges up normally.

    One quick note with those TP4056 module boards, they're typically configured for a charging current of 1 amp. You generally shouldn't exceed a charge current equal to the battery's capacity (usually referred to as 1C, meaning 1x capacity). For potentially damaged batteries you should aim a bit lower. In the case of Switch batteries (supposedly 4310mAh) this setup is fine, as the module will only charge it at about 0.23C. For lower capacity batteries, you MUST make sure to modify the module appropriately by replacing the current set resistor (there are several tutorials online), or find a similar module with adjustable current.

    After watching your videos I went & bought 2 Switch's off ebay as they were part of a job lot & going cheapish (£100), both apprently had faulty usb c ports but power on. One is in poor condition & not as per photos but weirdly seems to work fine so far. The other is in really good condition but the battery is dead & wont charge but powers up with the other one's battery. Going to try a few things before pulling the battery out. I seem to remember having a drone battery charger somewhere that's infinitely programmable and very good a reviving drone batteries so will have play around with that and see if I can hook it up and force some juice in to the Switch battery to wake it up. At worst I can at least swap the case & screen over from the working one to end up with at least one decent condition working Switch and the other just requiring a new battery. Eitherway thanks for these vids and inspiring me.

      THink I've found the issue with the dead Switch, USB port seems to be faulty. Put a volt meter across the battery terminals while charger plugged in and there's no reading. Did the same to the working one & got a steady 4.25 volts. So will attempt to solder a new usb port to the motherboard at some point when I muster the courage.

      @jandans1 You would be correct. But some gentle prying will release the tab from the board.

    • jandans1

      I might be wrong, but I think that these cells are spot welded to the protection board

  • Pha Q
    Pha Q 4 months ago +1

    If you're really feeling adventurous. The water damaged cell has bad battery protection with potentially good cells. The dead cells have a good battery protection board. Get where I'm going?

  • Pha Q

    Those cells may be two poly packs. You may need to charge up the inner red and black wires too.

    Hey Vince you still using that 853d rework station? Pretty sure thats what you said you had. Long time sub here do a lot of tinkering want to get into the repairs a bit more. I kinda killed my 862d today. Since I'm stuck buying a new one figured need a power supply anyhow. I used some resistance wire for a vape to patch it for a temp fix. It could last 6 months could last 6 hours as we know lol. So just gonna spend a bit and get a rework station with the 3 in one i guess it would be. Was hoping you may do a updated video on the station how you like it and stuff like that.

    The nice thing about LIPOs is that if they are going to get "pissy" about being charged, they tend to puff up and that disconnects the plates and prevents it from going any further. The reason 18560 and that sort of lithium ion battery explode is because they are inside a tin can and the plates stay in touch and get hotter and higher pressure until the bang and flames. You do not want the cell to go above 4.2v (and the TP4056 is designed to do that). So the way a lithium recharges is that you initially want to charge at a constant current and when it starts getting near the 4.2v it changes to constant voltage and decreasing current till it hits 4.2 and it shuts off.

  • Mu Aries

    I believe the module you have already has cell protection. The charge only modules have "battery out only" this one has battery and output
    If that is the case you could remove the built in circuit protection and use the cell via the module. Not for switch but as li-on battery even in parallel with others(balance all cells before solder them together)

  • John Hughes
    John Hughes 4 months ago +1

    Vince, can you not get the battery connector from a dead motherboard and solder the usb charger to it rather than mess around trying to put the wires in the connector of the batter? Also maybe try doing both + and both - together or something?

      Or a hotter setting on the hair dryer when I replaced the screen on a phone (2016 LG K8) I used one with the air turned down but the heat as hot as possible and kept the heat on low when it was being removed a little at a time.
      It's a screen and these are batteries but a little bit of heat while removing them might help

    when I revive lithium cells I always bypass the protection circuit and charge using the cells + and - terminals, then reconnect afterwards once I know the cell is good and can charge properly. I use a Turnigy charger that I use for various rc models so I can set the voltage and charge current.

    Vince please take care! when trying to revive Lipo/Lithium style batteries, back in 2013 i made the big! mistake off
    trying to save a battery by using a balance charger why waiting on new ones, i wanted to go fly my RC planes at the time.
    Why the weather was good, anyway i went to the bathroom on my way back i smelt burning and seen the flames creep up the wall.
    It was very, very frighting indeed, I managed to catch it quick and put it out, by the time i had it had caused a lot of damage to the extension of my house but..
    could have ended a lot more worse than it did, I also had other experiences of bad battery's DSi lite battery explode why on charge in the new! brick shed, a few years after
    the house fire, that was on its own charger! and one other time that didn't cause a fire but could have was the AA battery's in my RC transmitter melted it to a useless state.
    So Vince please for the love off us all whom enjoy you're content you make, take safety precautions. for your self, family, kids, pets etc.. Love ya dude (No homo) 😊🧯🧯👍

      @My Mate VINCE Ah yes a P51 most likely, not a good model to start learning with, way to much of a handful for a beginner. WLToys are not bad at all for the prices they charge, the name is a little deceiving to say the least, Helicopters are not toys in the wrong hands, especially when it comes to the flybarless models that are collective pitch, at least what you may have been looking at. when they add things like, ideal for beginner or suitable for new flyers, that is a bit of a naughty sales tactic. just because they have a axis-gyro that doesn't automatically make it ideal choice for someone new to flying.

    • My Mate VINCE
      My Mate VINCE  4 months ago +1

      @Steven Hawkins Thanks, I will look into them again, it was a low wing model...Mustang I think it was but it was all foam and very light weight. I nearly bought a 6CH heli recently, a WLToys version. They are cheap but I find their 4CH ones really fun and durable. Talking about it now really makes me want one!!!!!!!

    • Steven Hawkins
      Steven Hawkins 4 months ago +2

      @My Mate VINCE True! mate, there is options one of witch that I've been a member off for a long!! time. BMFA (British model flying association) they are super helpful and very nice, at least the guys i spoke with in the past. I guess you where flying a 4CH coaxial Helicopter. 3/4CH they are great for people to get into the hobby. If you pursue it and you get to fly collective & fixed pitch helis then the fun starts to get much more intense 6CH aerobatics is one that takes a lot of years practice. £60 sounds like a lot of money but.. in this hobby that's cheap and sounds like you possibly had a low wing model ? If you do fly again may i suggest you start with a high wing model like a Cub or Cessna, you'll have a much better experience I'm sure. iOS apps are fun but I'd also suggest you get a RC flight simulator for PC that way you can use a proper controller via USB or Bluetooth. Doing a video on it sounds like a great idea and would defiantly make a fun video for all us viewers, whom love watching you mate. 🤩👍

    • My Mate VINCE
      My Mate VINCE  4 months ago +1

      Haha, the premiums would be threw the roof :-) It is one thing I would love to learn how to do. I can fly a 4 channel helicopter now (not well but keep it in the air for the time the battery lasts). I bought a cheapo £60 plane but it just blew in the lightest of winds, I had no control over it. Definitely want to get a slightly better one to learn on. I seen a great iOS app that you can use a games controller on which mimics flying. I was thinking of maybe doing a challenge video on it :-)

      @My Mate VINCE I have big trees in my garden mate and the river is miles away from me, My bank insurance covers my R/C models etc.. I made the point of asking them if they cover them, I was told they do cover them as long as they are in the house or attached garage. they are not covered why out flying if they crash, that bit made me LMAO!! needless to say the lady dealing with me didn't take to kindly to me LOL at the time. I totally agree with you mate they should ask the customer about their hobbies. Look very much forward to your next *how to* 🤩

    To remove the battery easily, grab yourself some Dental Floss and some Goo Gone, put a lit bit of the goo gone on your dental floss then get the floss under a corner of the battery, and slowly saw your way through the adhesive underneath. If you need a better explanation shoot me a message for more in depth.

    Maybe you could try and find out exactly HOW these battery pads are attached to the circuit board.

    If they're just soldered on/through, I think you could use either your copper braid or your solder sucker to remove them. You could test by tapping your soldering iron on the dots for a while...
    If that's the case, do one side at a time. When all the solder is gone, pull it off, wrap it in non-conducting material (like maybe tape? that Capton Tape could work), and begin work on the next.

    It's a win that you salvaged one battery for your future Nintendo Switch repairs Vince. I suspect faulty protection/charge board attached to the battery(ies). The batteries themselves seem good and, whilst no longer useful for the 'Switch', they will make great sources of re-chargable power for other projects. Simply remove the built-in battery protection boards, purchase 5 TP4056 boards from China (£1.20 for 5) and connect one directly to battery +/- terminals. I have done this with old phone batteries and, in some cases, attached a boost converter to the TP4056 output to give me a great 9V power source for guitar pedals and other low current devices. Really an easy, reliable and cost effective way of re-cycling.

    The grey pin is probably to a thermister / protection circuit inside the battery that would halt charging if the battery starts to overheat.
