Thanks for posting the fix. I did a solderless fix. I purchased a 2032 battery coin holder that holds two batteries side by side with an on/off switch with wires attached also. Unfortunately, it only works as 6V when the batteries are in the holder. So I needed modify it to make it 3V. I used about 1 foot of 24 gauge wires split into 6" lengths, one for the positive and one for the negative. I removed two small screws that held the top cover to the bottom. Then I cut off the switch which wasn't needed and removed both wires from the holder. With one of the new wires, I wrapped the wire around the bottom metal contacts that touches both batteries. I also wrapped the second wires around the top cover metal contacts that touches both batteries also. Make sure you have the wires leading out of the holder so you can attach it to the battery of the cooker. You can use a longer wire if you want. Now place the batteries into the holder with both facing the same way. Either the both positive facing down or both negative facing down. The polarity both need to face the same way. That's called connecting batteries in parallel where the voltage remains the same but the mAh increases and in this case 3V voltage and a total of (210 +210 each battery) 420 mAh. Screw the top and bottom back together and test the voltage with a multimeter to make sure your connections are good and you have only 3V. If it reads 3V, label the polarity of each wire and you're good to now attach it to the old battery. Strip off about one inch of the rubber casing from the wires. Place several strips of electrical tape underneath and by the leads of the cooker's original battery so to protect it from any faulty touching from the new wires. With the positive wire wrap/twist it around the positive lead/post of the old battery using a tweezer if you need. Do the same with the negative wire to the negative lead/post of the old battery. When wrapping/twisting the wires around the leads/post, make sure no wire strands are touching anything but the post or the correct polarity of the battery. The top of the original battery is positive so make sure the negative wire/strands doesn't touch the top of the battery. After the holder wires are connected to the old battery, the screen should come on and will read 7:00. If it does, you have attached it correctly and fixed it. Now run the two wires to the bottom of the board and up the back of the board ( opposite the screen side). Put some electrical tape on the back of the board where you plan to tape the the battery holder so not to have the battery holder scrape the contacts on the board. Attach the board back on to the cooker before you tape the holder to where you want. It will be easier if you do that first. Reassemble the cooker. Plug it in and test all the buttons to make sure the board is aligned correctly to the buttons and the screen show correctly. Now if the battery ever dies, all you need to do is change both batteries, no need to unsolder and solder new batteries. Mine is working great. This write up seems to make it long but doing it was very easy and quick. The battery holder was $6 for ten on Amazon and the two 2032 was a couple of bucks. You can get the 22 or 24 gauge wire through Amazon also. It's very easy. Don't be afraid. All you are doing it wrapping/twisting wires around the post. So if you don't get it right just unwrap/untwist the wire and put it back together again and you're back to where it was with it still working as before with a dead battery. If you try soldering and don't do it right then you can screw up the board and it won't work afterwards. Good luck
So just to be clear, you left the old battery in the unit, and just wrapped the wires from the new battery holder around the existing posts with the old battery still connected?
@@cl650pilot Yes, you leave the old battery intact. Just wrap/twist the new wires to the old battery post. It's that simple. I just changed the batteries today Feb 3, 2023. Opened up the unit again, popped out the old batteries from the battery holder and installed new batteries. Everything is working fine with the cooker. And took less than 3 mins to change batteries.
Thanks for this guide. Given that most of the 2354 batteries available on Amazon and eBay are counterfeit and have a questionable longevity, I instead bought a 2450 battery holder (Keystone 1025) that had tabs that lined up with those on the original battery. I then soldered it to the green side of the circuit board. Not only are 2450 batteries readily available in hardware stores, but I can now replace it without any further soldering.
@@Koji-888 I removed the old battery. There was enough clearance under the tan plastic piece to get my soldering iron under it without removing it, but it was a bit tight.
@Zan Hecht I tried this. At one point when I first popped in the battery, the LCD turned on. But the holder was still a little loose on the circuit board, so I added more solder. I removed the battery before soldering, and when I put it back, the LCD stayed off. A multimeter showed 3.2 volts across the battery holder contacts on the other side of the board, so the battery seems fine. Eventually I gave up and re-assembled the cooker. The buttons and LCD work fine when it's plugged into AC, but the battery doesn't seem to be working. Any suggestions? (I have soldering experience making microphone cables, but am otherwise a novice when it comes to electronics.)
I found that by using a dremel to make a half-moon cut into the Keystone 1025 plastic (up to the negative plate), I was able to get to the underside pin with my Hakko and solder it properly.
I found that a Torx T20 tamper-proof bit worked perfectly without modification. Mine was part of the Craftsman 33-Piece Screwdriver Tamper-Proof Bit Set (Model #47846 from Sears).
Thank You, your step by step instructions were the reason why I was able to replace the battery...Thank You for taking the time for making the video. My wife is extremely happy to be able to use the timer and schedule the cooking for rice.
I got a small flat head 2.5x40mm and pry it in between the hexagon screw and I was able to force it to come out 😅 Thanks for this video. They definitely didn’t make it user friendly to get this battery changed but it’s so doable thanks to your very detailed step by step instructional video. Thanks so so much!!😇
Thank you so much for this video! Such a public service, we appreciate you for sharing it. Thanks to you, my husband just replaced the battery in our Zojirushi rice cooker, and my friend's (hers a 3-cup.) Please keep the video posted, we'll be back in 10 or so years ;-)
Hope my experience will help. I just soldered 2 wires to the botton on the main board (check the polarity!!) to the contacts, put the endings to both sides of the battery and just wrapped the battery with adhesive insulating tape (I used cr2032 as a most common 3v battery, you can use ANY). after that I used 2-side sponge tape for the battery to attach it to the main board. it's working FINE. no need to detach the old battery and all plastic components, solder the battery and so on. just make sure the battery is attached firmly to the main board or insulate it carefully in case the adhesive tape loses its properties with time and may short (which is very unlikely as it weighs 4 gr).
Thank you so much cg00n for sharing the details of replacing the rice cooker battery! I bought exactly the same model more than 15 years ago. The clock went off recently. It starts at 7:00 every time I plug it to the power. And three days ago the clock/timer stopped displaying while the cooker still working. I realized it could be the on-board battery issue. Luckily I found your video here, which showed step by step how to do the tricks! Also thanks to Zan, the idea using a battery holder is cool as I have no idea how long the new cell would last. I ordered CR2450 and the holder from Amazon and got the parts an hour ago. 50 minutes later, I’m a happy guy again!
If I'd known how popular this would be I would have had a proper musical score and credits for it :-) I'm glad it helps. There is a lot of really useful stuff on TH-cam and elsewhere, worth remembering when the Evil Internet comes up for discussion.
@@cg00n when the battery was running low, did the rice cooker also stop working? I think my battery is also low - also showing 7:00 and the timer stopped displaying, but I'm starting to also see the heating element turn off way before the rice is done then I'm unable to start it up. I would unplug it for awhile..and replug it back in to get it to work. Noticed the menu arrow goes away when this happens. I want to see if I should put any effort in changing the battery if something else is also failing. Thanks!
@@austinngo2861 The battery on my NS-ZCC10 ran out recently; so far it cooks rice without any issues. It sounds like yours might have other issues in addition to the dead battery.
Thanks for posting this cg00n. It's a shame Zoji didn't just make the battery easily replaceable from the outside. So far my original battery is still working but my unit is getting old and I want to be ready to replace it when needed.
Even if the battery replacement would still require removal of the base, the battery itself should've been mounted in a holder socket as done on digital watches. The fact that it's soldered onto the board is so shortsighted. Zojirushi invested a lot in making these rice cookers long lasting. I have the NS-LAC05 model (3-cup) and it's so well made... but the battery has been long dead. Thankfully coin cell batteries do not tend to leak as they age. I'm just not going to bother replacing it as I don't use the clock.
Thank you, this gave me the courage to tear apart my rice cooker. I took a bit more permanent measures to ensure I never have to do this again. I purchased a cr2032 battery holder with leads from Amazon, and ran the cables through the air slots on the base of the rice cooker, and soldered them on from the back of the board. Never again do I hope to have to open this unit up. The one thing I'd personally recommend doing differently than you did, was rather than snip the battery (which could put lots of pressure on the board), I put a longer set of tweezers in there to pull the battery away from the PCB, and then used a soldering iron to loosen the prongs from the battery.
That's a great idea. It's a real shame Zojirushi didn't do this as part of their product design. I have the NS-LAC05 (discontinued) that is so solidly made, but the battery went flat years ago. (It's a 14 year old unit). So a single CR2032 battery is a fully compatible replacement? No resistors required?
@@cytherians yeah, no resisters required. The only issue I found with CR2032 is the battery life wasn't the best. I ended up changing things up a little bit later. Ordered B08119TXFH from Amazon, which is a AA battery holder. Two AA batteries gets the correct voltage (3V), no resisters required. I just glued the battery holder to the side, drilled a small hole to run the wires into the rice maker, and soldered the wires straight to the PCB where the old dead battery was. It has been going strong for over a year. If and when I need to replace the batteries (which will be a long time from now) it's just a quick swap with no disassembly required. The clock and memory has stayed on this entire time, it's been great!
@@JeremyJensenTheOriginal Thank you, Jeremy. I just checked that holder and it looks good. I like the casing design and 2xAA makes a lot more sense, especially since there's ample room inside the rice cooker casing-shell. Did you just snip the leads to the dead battery and then solder directly to the tabs?
@@cytherians I used tweezers to gently lift up the old battery while using a soldering iron to loosen it up. So I was able to cleanly remove it. Clipping should work too. I decided to external mount the battery pack on the side so that I could just swap the batteries easily in the future. It looks like it could have fit inside, but I dislike taking it apart. I could have run the wires up through the bottom vents, but I opted for a cleaner look by drilling a tiny hole in the side of the unit.
Thank you for this video. It allowed me to determine that I do not want to tackle this repair. My question is, why does Zojirushi make it so complicated to change a battery? Even if customers return the unit for the manufacturer to do, the technicians will essentially have to jump the same hurdles, albeit more proficient as they do this more than once, but nonetheless a pain in the butt to get to. We will just continue to use the unit with a dead battery. We just can't preset to turn on ahead of time. We can live with that inconvenience.
Oh but you can preset. You just need to reset the clock every time you want to use the timer. That being said: I will too continue to use the unit without changing the battery. And why the f*** was this unit designed with so little consideration for customer friendly battery replacement. The rice is really really good but the poor design in this regard is mind boggling.
@@stefan.markun I have the same issue on my NS-LAC05. It's built so very well. Nearly 15 years now and it still works like it did when new. Since Zojirushi built these so well, why did they think people would ditch them after 10+ years? They definitely should've welded in place a CR2032 socket for simple replacement as CASIO has done on their digital watches since the 1980's. I'm just thankful that the CR2354 coin cell battery is a type that very rarely leaks.
Thank you! Just fixed mine today and replaced with 2450 battery, should last me another 5 to 7 years. The soldering is not hard at all. Super wick is a lifesaver
I believe this must be specifically for this cooker. I have one a few years newer and it is much different inside. I actually could not find the battery on my unit. It was not in the place behind the LCD Screen. I ended up taking it to my Zojirushi service center.
Braid, a soldering iron and Amtech Flux will desolder that battery off and just solder a new battery holder for not needing to solder again, clean flux with alcohol and a swab, a new battery and done.
Thanks for video. If I every get the courage might try this 😐 but have never soldered anything before. I think I will just live with no clock at least for now ☺️:
were you able to discern where the heating element is? is it that part at the bottom, or do you think its encased in something that allows for even heating?
Nice job. Got to laugh how difficult they made it to replace a battery that is sure to fail after 6 years. Seems like they might want you buy a new rice cooker when the battery fails. 🤔
I am having an issue. I was able to change the battery and the clock works but when I plug it in and none of the buttons work. I tried to look for any information on this but i didn't find any. I hope you can help me with this. Thank you.
I wonder if you could just remove the old battery and solder leads to the board to a remote battery stashed somewhere else. Great video though, thanks.
I just did exactly that. It makes it all much easier since you don't have to shoe-horn the replacement battery into the old spot. I used a CR2032 and a battery holder, wired it to the old solder pads, put some heat shrink tubing over the battery and holder, and stuffed it behind the control board.
@@Jason.F. Yes but it could be that the circuit board is acting like a heat sink I was thinking of doing the same thing and simply attaching it. After more than 12 years my battery finally took a dump
Hello I have a US version NS-TSC10 used an adaptor the moment it turned on it blew got a little burning smell. I'm my very technically minded I have to admit but am wondering if you know if it's a problem that can be solved?
It's criminal the way all these expensive rice cookers hide their battery deep inside and say it's forbidden for users to try to change their own battery. They just want to sell you a new rice cooker when the battery wears out. Maybe in Asia you could bring the rice cooker down to the corner and have it fixed in an hour for a couple of dollars but here in the USA they want you to mail it to the factory at your own expense both ways and who knows how long they'll keep it. There's no reason that batteries can't be easily replaced like a flashlight battery or any other appliance, except they want to sell you a new rice cooker when the battery wears out.
I have this model, and it is less than 2 years old. Worked great, and then it fell about four feet onto a tile floor. None of the plastic cracked, and the clock was still working, so I figured it survived the crash without damage, but upon trying to use it the next day, it would not work. None of the buttons did anything. Does anyone have any idea what might be wrong with it? Is it repairable? There is an authorised repair shop in the larger city about 1 to 1.4 hours drive from my home. They charge $25 to diagnose it. To ship it there would cost $20-$25. To ship it back would cost $20-$25. I have no idea what parts and labour might cost, but I imagine they could easily cost $50-$100, maybe more. Adding up all of this makes it a poor option since I could purchase a brand new one for about the same cost or a little more. I am so upset. I took such good care of it. This accident was so tragic. Is there any chance I might be able to diagnose and repair it myself? I have zero experience in such things, so I do not feel very confident about it. 😪
Did you know why the rice cooker smell bad. What's issue. Do you know why my Zojirushi NS ZCC10 rice cooker smell bad? After making the rice, leave it all night in the morning the rice have some bad. Where does the bad smell problem come from?
It could be has soldering gun older ones had a cooling fan. And I'm guessing he might be in a European country so that soldering stations might be different than US. But you definitely want to use a grounded soldering iron/gun that's adjustable preferably.
I like your wry sense of humour. "The battery is conveniently located here ...".

I avoided Zojirushi when I bought my last cooker specifically for this type of scam.
Nice job. Got to laugh how difficult they made it to replace a battery that is sure to fail after 6 years. Seems like they might want you buy a new rice cooker when the battery fails. 🤔
Just bought a new one . Found that a battery needed to be replaced that’s why I went to you tube. How long does it take for the battery to fail ?
I am having an issue. I was able to change the battery and the clock works but when I plug it in and none of the buttons work. I tried to look for any information on this but i didn't find any. I hope you can help me with this. Thank you.
I wonder if you could just remove the old battery and solder leads to the board to a remote battery stashed somewhere else. Great video though, thanks.
I just did exactly that. It makes it all much easier since you don't have to shoe-horn the replacement battery into the old spot. I used a CR2032 and a battery holder, wired it to the old solder pads, put some heat shrink tubing over the battery and holder, and stuffed it behind the control board.
@@lensherman6242 great minds think alike.
@@Jason.F. Yes but it could be that the circuit board is acting like a heat sink I was thinking of doing the same thing and simply attaching it. After more than 12 years my battery finally took a dump
Hello I have a US version NS-TSC10 used an adaptor the moment it turned on it blew got a little burning smell. I'm my very technically minded I have to admit but am wondering if you know if it's a problem that can be solved?
I have burn marks on the base of my rice cooker. Any ideas?
It's criminal the way all these expensive rice cookers hide their battery deep inside and say it's forbidden for users to try to change their own battery. They just want to sell you a new rice cooker when the battery wears out. Maybe in Asia you could bring the rice cooker down to the corner and have it fixed in an hour for a couple of dollars but here in the USA they want you to mail it to the factory at your own expense both ways and who knows how long they'll keep it. There's no reason that batteries can't be easily replaced like a flashlight battery or any other appliance, except they want to sell you a new rice cooker when the battery wears out.
Will the rice cooker still function with a dead battery?
Yes
Hi, what do u think happened I put my 120w zojirushi into 220w and ofc after short noise it stop working, what should be replaced only battery?
Make me not want to buy a Zojirushi.
I think you may have just inadvertently given me a reason to NOT buy this.
Jeez it got worse as it went on lol
This dude makes me nervous touching a circuit board with a metal screw driver 😫
This dude wonders why you are concerned. Please explain!
I have this model, and it is less than 2 years old. Worked great, and then it fell about four feet onto a tile floor. None of the plastic cracked, and the clock was still working, so I figured it survived the crash without damage, but upon trying to use it the next day, it would not work. None of the buttons did anything. Does anyone have any idea what might be wrong with it? Is it repairable? There is an authorised repair shop in the larger city about 1 to 1.4 hours drive from my home. They charge $25 to diagnose it. To ship it there would cost $20-$25. To ship it back would cost $20-$25. I have no idea what parts and labour might cost, but I imagine they could easily cost $50-$100, maybe more. Adding up all of this makes it a poor option since I could purchase a brand new one for about the same cost or a little more. I am so upset. I took such good care of it. This accident was so tragic. Is there any chance I might be able to diagnose and repair it myself? I have zero experience in such things, so I do not feel very confident about it. 😪
Did you know why the rice cooker smell bad. What's issue. Do you know why my Zojirushi NS ZCC10 rice cooker smell bad? After making the rice, leave it all night in the morning the rice have some bad. Where does the bad smell problem come from?
Fan noise in the background is distracting
It could be has soldering gun older ones had a cooling fan. And I'm guessing he might be in a European country so that soldering stations might be different than US. But you definitely want to use a grounded soldering iron/gun that's adjustable preferably.
