CMOS battery hack | Laptop CMOS battery

The CMOS battery enables the computer to remember the date, but when the battery goes flat the computer will revert back to the date of manufacture. Changing the CMOS battery can be difficult on some models. Many laptops use a special type of battery with leads soldered onto it, but soldering the leads onto a battery is very dangerous. This video shows how to convert a regular coin battery to a battery that can be used in most laptops for a fraction of the price.

Must make sure that you're replacing the CMOS battery with the same type of battery. Some use non-rechargeable ones like the CR2032 shown in this video. Others use rechargeable ones like ML1220. You risk damaging either your laptop CMOS charging circuit or causing the replacement battery to leak/explode inside your laptop if you use a non-rechargeable in place of a rechargable battery.

I know this was some time ago, but actually this is not correct. Laptops us CR2032 Lithium batteries and not ML rechargeables. Also most rechargeable batteries cant reach the needed voltage or die much quicker. The CMOS system uses such little power a rechargeable isn't needed. So as long as your laptops one was CR2032 and you replace with the same you're all good

Thanks for making this video. You saved me probably $30. I had 3 Intel NUCs that all needed the battery replaced. Luckily the existing batteries had flat metal connectors on the ends of the wires that I was able to pull of the batteries and use to connect to the new batteries. Also, luckily, I already had some aluminum metal tape that would normally be used for sealing duct work (not duct tape, the metal kind). It worked great. I didn't have any heat shrink. I just wrapped it in electrical tape. Hopefully, it doesn't melt and make a mess for the next time I need to replace the batteries. Other than that, was glad I was able to immediately replace the batteries and save some money. Thanks for taking the time to make this video. It was very useful. Also, people were complaining the ones I was going to buy on Amazon sometimes had the wires backwards. I would rather make my own and make sure they are wired correctly. Pretty pathetic quality control that a company would let that happen.

[@ultimatehandyman]

I'm glad the video helped 👍

[@savatagedude]

Just what I was looking for!! Was about to solder too. Mine had a contact attached to the wires already so I made it flat as possible and wrapped the electrical tape tightly around it and seems to be doing the job. I swapped out the original 1620N battery with a 2032. Same voltage, etc just 3 times more MAH. Thanks for posting

[@gimmietheprize]

Brilliant tutorial. I successfully replaced the CMOS battery in my HP Pavillion DV2 laptop today following your guide. I think the plastic shrink stuff that I ordered may have been a bit too wide as it didn't shrink wrap like yours did but it still did a good job and the laptop is now happily using the CMOS battery hack.

That brought back a memory! When I was about 12 (30 years ago, lol) I briefly connected a button battery to a 6V dc power supply to try and recharge it, and it exploded. I was lucky like you, nothing went near my eyes.

[@ultimatehandyman]

It's amazing the size of the explosion from such a small battery! I'm glad that you were also lucky ;-) Thanks for the comment

[@michaelszczys8316]

I have recharged batteries like this a little, just to see if something still worked. You have to keep the charging supply small, just a little higher voltage. These batteries are made to be charged but not real fast. Hook it up to a couple AA batteries

[@abetter5]

You can remove the wires from the original cmos battery and keep the connector intact. Use the conductive tape and the heat shrink to connect the wire to the new battery and viola, a new cmos battery ready to install.

Yep, just did the same - even after seeing the thumbnail for this video and thinking I knew enough - the solder didn't stick to the battery surface, and by then the battery was very hot, probably ruined, but cheap, and it didn't explode - so I came back to see how it's done.

[@TheHallucinati]

Believe it or not hockey tape works even better for this hack than insulation tape. When it dries from the heat generated inside the laptop - it tightens. Insulation tape does the opposite actually. It tends to expand and the glue sloughs off in a huge mess. With hockey tape you don't even need to use heat shrink pocket.

[@lonniebiz]

Ah, conductive tape . . . Well, I'm just now seeing this video, and I used electrical tape exclusively, but thankfully it still worked. I guess, as long as you do it in a way where each wire remains exclusively touching on one side of the "coin" (without those wires ever touching each other), you'll get by. Apparently, this CR3025W, is simply a CR3025 with a wire and connector attached to it. I had to replace one of these in an Intel NUC. I'll buy some conductive tape for the next time. Thanks.

Was wondering how to go about doing this - and you've shown me. Thanks.

[@phreaktor]

Is it absolutely necessary to use the conductive tape to get the least impedance or would flattening and spreading the wire leads a bit and then using the electrical tape wound tightly be sufficient? I don’t have any conductive tape. What about an aluminum foil tab (no adhesive) then electrical tape?

[@ultimatehandyman]

Don't worry too much about the conductive tape, it will be fine without it. That was just a belt and braces approach. Thanks for the comment 👍

[@kribbathome]

Best method is to spot weld, like they do on these from the beginning. It's possible normally to just rip off the old weld without rupturing the nickel strip. Just be careful to not short the battery, like you did when you tried to weld it. Using a little bit of electric insulating tape is all needed.

Thanks, needed the advice. Fixing a friends laptop and keep killing the button batteries (don't know where to get the one I need, but have cr2032's aplenty and keep killing them trying to solder leads on). This will work wonderfully. I don't know why I didn't think of this.

Same. If I'm doing all this to avoid waiting for shipping (amazon can get me one in 2 days) and save a buck or two, but I have to buy conductive tape, heat shrink sleeves and a heat gun? How long for all that to arrive and how much more expensive than a battery? I have a feeling that just wrapping it well in electrical tape and calling it a day would be fine in most cases.

[@lupo631]

@@ultimatehandyman You're welcome!

[@lupo631]

One hint after replacing the new battery in place: Check the thickness! In my case the shrinking insulation hose was too much. So it didn't fit into the battery bay. The insulation tape was the maximum I can wrap the battery around otherwise it will not fit. Lupo

[@samirgunic]

It seems like history is repeating itself. Both of these ideas crossed my mind: soldering the wires onto the battery directly, or wrapping the wires in place with insulation tape and then adding a heat shrink for good measure. The latter seemed most convenient as I don't like to solder. But wow! Good thing I found your video and saw what can happen if you try to solder onto a battery. So not only is taping it together more convenient, it's also the secure way to do it. Short of only doing it professionally with a spot welder, like they do in the factory. But why use a copper tape I wonder? I have never used one before. Is the adhesive conductive on this type of tape? I could not find a definitive answer to this fairly simple question from local suppliers. Apparently, people that buy copper tape are mainly concerned with snail invasion, so it's sold as a pesticide. They don't really care if it's conductive or not, as long as it keeps the snails away from their plants. LOL! I had a good laugh at this! :) It's the first time I hear about this. I learned something new about snails in my search for conductive tape. So they know that it works for snails, but they can't tell if only the top side of the tape is conductive or if both top and bottom side are conductive. I know there are such things as conductive adhesives or glues. But since a single roll costs about 9€ (about 8£) and I didn't know if it would work, I decided to get it elsewhere (or not at all). I think I will order online, along with the appropriately sized heat shrink tubes. The CR2032 is 20 mm in diameter and the biggest heat shrink tube I have is 19 mm wide and it won't go on even if I push it. So I will get the right size and some copper tape (to satisfy my curiosity about conductivity). I might as well skip the copper tape. I have preserved the battery terminals by prying them up and then flattening them out with pliers. I found a guy from Latin America (Argentina) did the same, and then he rolled them up a little bit like hooks, and then just taped them to the battery. That way you get more volume to press against the battery as you wrap the tape around! Clever! He also added a small piece of tape in between the wires to prevent shorts. You can see his video here: kzbin.info/www/bejne/qafXeGevpch-h6M It's hard to believe that people are still changing their CMOS batteries this way. It's a good thing that we still can change the batteries on electronic devices. I'm currently doing some work on a 22 years old Fujitsu Siemens laptop for an acquaintance of mine, and I measured the battery voltage to 0.43 V. It's no wonder both BIOS and Windows were complaining about wrong date and time. I have a handful of these CR2032 and a mix of other button cell batteries, brand new and recently purchased. I just had to improvise to get one in. I have not worked on a laptop before that didn't have a CR2032 socket. It must be the very old ones that didn't have a socket for a CMOS battery. In any case, thanks for the video!

[@RonAblang]

Must I use the 2 different types of tape or can I just use electrical tape for both tape types?

[@ultimatehandyman]

It will probably work with just the insulation tape, the conductive tape is just to guarantee a good contact between the wire and battery.

[@JUSTONELOOK]

Thank you for this video! What size heat shrink tubing should I get? 20mm? 25mm?

[@ultimatehandyman]

You are welcome. I can't remember which size I got but from what I can remember it was inexpensive, so perhaps get a short length of both to be on the safe side. Thanks for the comment

Great video, well done; however, in the U.S., the conductive tape is about $10.00/roll, & a pack of heat shrinks is around the same. So that's around $20.00 right there, vs. an $8.00 replacement battery. I might have to hack your hack & do some workarounds. It would be great if you made a video how to do a poor man's hack if they don't have those things. I'm sure something could be worked out with aluminum foil, or maybe not even use something conductive, just tape the wires down... & then in lieu of a heat shrink, just double up on the electrical tape.

hi guys and hi handyman, well done! a question for you: my acer l3600 has a cmos battery wrapped like yours but it's connected to three wires (red, black in the middle and white)...why? and how should I connect the wires? tks 4 your videos ;)

[@ultimatehandyman]

I'm not sure about that, I have only ever seen them with two wires 🤔 Thanks for the comment 👍

[@armandodestito9042]

@@ultimatehandymantake a look on eBay or Amazon, or similar, if you want. I think that the 3rd wire is for the charging feedback of device. Bye

dat explosion though...scary, but thanks for the early warning one question, can i just tape the wire onto the battery using normal electrical tape, and then cover the whole battery with more tape?

[@ultimatehandyman]

Vann Mizan Yes, that should be fine ;-)Thanks for the comment

[@VannMizan]

how about "the mess" done by that electrical tape when exposed to laptop's heat?

[@ultimatehandyman]

Vann Mizan Does your laptop get that hot that it will melt the tape? If so you might be best off using some heat resistant tape?

[@VannMizan]

its my sister's, and she' s like typical user

[@Erdy007]

[@ultimatehandyman]

Yes, it will be fine 👍

What type of connector do they usually use these days for those batteries? Is it something like a 1.5mm or a 2.0mm pitch? I have an ITX Z390 motherboard, and the connector for its battery is located near the rear I/O and it has under a heatsink that covers that area. Gonna be a chore to get at without taking the entire motherboard out...

I'm not sure. I did buy some, but can't find them! Thanks for the comment 👍
