I bought a replacement cmos battery on ebay but the laptop still had the bios error. After days of looking for a solution, I finally took the battery apart and tested with a meter, found out it was dead. I was looking to see if I could salvage the wires by swapping in a battery I could buy in a store, like this video shows....however, reviews of those specific dollar batteries say they're often dead too, so I recommend testing them before doing all the work shown.
Thank you for your video. This helped me a lot for my PS3 FAT CMOS battery replacement. So what I want to contribute is to add something that could be helpful to others. I first used a papercutter and bend the metal tabs upwards all around the perimeter. My tabs had 2 placed spot welded. So I them put the tip of the blade onto 1 spot and hammered down a bit. I am lucky my paper cutter has a metal body instead of a plastic one. I did not need to hammer hard. This dislodged the first spot which I could then twist free. I repeated this with every other spot and got the tabs out cleanly. No cuts, breaks, or holes.
Hi so im having a problem whit my laptop turning on but theres no display on screen i checked the ram, hard disk, and the screen display cable. Still not working could that have anything to do whit th e bios battery?
Yeah, I don't think it's tape; looks like two strips of metal that were spot welded onto the battery. Looks like the guys at Lowes weren't crazy after all lol
Those connectors ARE spot welded on there from the factory but, if you try to solder those contacts on yourself that battery has high chance of exploding. This hack will do the job just fine. Good job on saving the metal strapping. Makes it so much easier. They do sell copper conductive tape for taping down bare wire/metal to the other surface that is conductive. The conductive tape gives you better chances for a solid connection by increasing the total contact surface area. That was probably more info than you needed. Loved the video, man. Thanks!
bubba: That was my initial thought, but other videos, including one that actually show such a battery EXPLODING while trying to weld it say NO. Not using a weld is why the conductive tape (like copper) to give a GOOD and secure connection, AND tightly wrapping in plenty of electrical tape AND heat shrinking the tape a bit is all a good idea. With the pressure of the laptop case on that package, that SHOULD provide a secure connection for years, assuming you're not playing rugby with your laptop.
As long as the connection is "tight" / firm , there should be no loss of electrical contact. Taping it securely and pressure from laptop case should keep wire contacts in place fine. Normally these are spot welded with a special spot welder (doesn't overheat the lithium batt).
I know this is a little late but HVAC aluminum tape can be bought at any big box store for a few dollars and athough its conductivity is slightly lower than copper's, aluminum tape offers excellent electrical performance and shielding characteristics.
thanks for showing us a cheaper option , I would not trust the contact that what you just have taped up , I would have solder them for firm contact then tape up
thanks for watching, its been about a year now more or less and its still working, if you solder battery might blow up, please be careful

Why on earth would you need such a firm contact on a CMOS battery? 😄 You can even cut those tabs off if you want, peel a centimeter of the insulation and use an electrical tape to attach the wires to the battery, just as TTT did, then use a piece of double sided tape to attach the whole thing to where it is supposed to sit in the laptop.
I have a Asus Vivobook X540MA and would like to know where the CMOS battery is located, I have opened the vivobook but can not locate the CMOS battery. "help"
It's not even the money, it's the fact that you can use a battery that you know is fresh, instead of one of those pre-sealed ones that could have been on the shelf and worse than the one you're replacing.
Alexander Montero: Another video I saw on this mentioned either copper or aluminum tape as examples. The idea is apparently good quality conductive metal tape, to ensure a solid connection that will last.
Janburn Dayanan: The voltage, the current, and the size all matter. There is a reason for the various battery numbers. I wouldn't be substituting without knowing what I'm doing, as I don't know how sensitive the tolerances for different voltages or currents the laptop components might have. Actually, you should replace whatever your laptop has with the same type of battery, to be safest.
@@TitaniumTronic actually we can...i tried it and made a video about it
Рік тому+1
@@TitaniumTronic of course you can. The only difference between CR2032 and CR2025 is capacity. CR2025 being thinner will have lesser capacity, therefore it won't last as long as CR2032.
Harushita: Look for a repair manual for your laptop on the internet. You might just have a bare battery (many older models do). You don't want to get into all this until you know WHAT you need to replace. My Dell E64x0 series laptops (I love them for very easy repair and drive access) makes it easy to find the info on the CMOS battery for replacement, for example. Dell has all such manuals easy to find and download on their site. (Such info is getting to be important re purchase decisions for me, as I like to make things last).

Thought: Cut that heat-shrink tube diagonally to get a band that has a bigger opening than the normal tube. Maybe criss-cross them?
Your hack method is worked for me. I replaced a 2032 CMOS battery for my HP DM1-2000 series laptop, following your video. Thank you so much!
thank you for sharing ill should try this later!
update....it worked for me!thanks again!
Hi so im having a problem whit my laptop turning on but theres no display on screen i checked the ram, hard disk, and the screen display cable. Still not working could that have anything to do whit th e bios battery?
....thanks man, the best i've found is your technique..cheers. For others; stop wasting search time..
That was not hard at all!
Thanks for the video!
I can stick them first with a small copper foil tape before covering with electrical tape
I think the tabs are supposed to be welded onto the battery casing
Yeah, I don't think it's tape; looks like two strips of metal that were spot welded onto the battery. Looks like the guys at Lowes weren't crazy after all lol

But other laptops only have cmos battery sitted on board and not welded
You're a life saved man❤❤❤
I think my dad needs this~ he has a cmos batt for his laptop~
Thanks a lot in africa it is hard to find thes battery ❤
I did the same at my playstation 2 ! I put the contacts wire on battery and after that i put the tape. Work very good.
Awesome THANKS Good job👍👍👍👍👍
Obrigado pelo vídeo!! Salvou brasileiros 🤣🤣🤣
I don't have a hair dryer, what happens if I don't heat shrink the electric tape?
As long as the connection is "tight" / firm , there should be no loss of electrical contact. Taping it securely and pressure from laptop case should keep wire contacts in place fine. Normally these are spot welded with a special spot welder (doesn't overheat the lithium batt).

Allow me to give you a battery hack. Never touch the terminals of the battery with your fingers because you risk discharging it.
Can't find this battery I have acer laptop
I have a Asus Vivobook X540MA and would like to know where the CMOS battery is located, I have opened the vivobook but can not locate the CMOS battery. "help"
I recommend using this LJ-CMOS-4 battery.
Good Vid mate
Really helpful thank you
Regards from the UK
Yes I knew it
Can i use any brand of coin battery for any laptop?
Yes any brand,
I'm sure you can just take out the battery itself and not the whole plug in entirely.
It's not even the money, it's the fact that you can use a battery that you know is fresh, instead of one of those pre-sealed ones that could have been on the shelf and worse than the one you're replacing.
Dude that's not a hack. It's just a battery replacement
I have a pc and am trying to remove one of these batteries. It’s hard to get out and I don’t want to risk breaking it.
Thanks
how about aluminum tape?
Alexander Montero: Another video I saw on this mentioned either copper or aluminum tape as examples. The idea is apparently good quality conductive metal tape, to ensure a solid connection that will last.
Absolute lifesaver. Earned another sub
thanks
Awesome and Thank You TTT
Thanks man!
thanks ❤
How do you know battery was not rechargeable ? Don't think you can just swap then.
CMOS button batteries are always non rechargable, same for PC and laptops it is just to keep custom settings and time.
can I replace 2025 with 2032 cmos?

The things you call tape are terminals spot welded on the battery. But yeah conductive tape does exist.
The battery will explode if you try to solder the wire directly as shown in another diy video: ua-cam.com/video/5DdAZrTZjEM/v-deo.html
@@Spiritgumm spot welders are designed for welding batteries. Don't you know what a spot welder is?
@@jrgmty7685 Nope, but I thought it was worth sharing the mistake that other guy made.
