CMOS battery help

[lccpor123]

Hi, need help frmo you bros here.

Wondering where I can get this type of CMOS battery as shown:

TIA!


EDIT: Forgot to put more info, this is from a Asus Vivobook S551LB laptop, BIOS date time always reset to 01/01/2009, hence i suspect CMOS batt uplorry.

Well if no one knows, maybe it will be the best for you to bring down to SLS and look for those laptop shop and check if they do sells that battery or not.

You can buy from Ebay. Search for "CMOS RTC battery".

Okay thanks for the ans, will bring the battery down to SLS to take a look

I prefer to buy from physical shop tho, buy from Ebay need wait
Anyways thanks for the ans

Actually, if it's not soldered, I wonder if you can just tear open and replace the battery.

Saw some pics of 2032 version, machiam scotch tape around it, lol.

Can try emailing this SLS shop to check.

Is called heatshrink. And yes once you take it apart is just the same 2032 or 2016 button cell.

Its a CR2016 battery. Just bought mine from qoo10.

But this CR2016 battery is attached to a connector. Soldered to it.

Haha had thought of DIYing it but scared when solder will sexplode

If really cnnt find the exact one will try experiment, wish me luck

So as long as is 3V button type lithium is okay?

Will try!


Thanks guys for the inputs!

Your is CR2016 3v so must replace back a CR2016. If you want DIY then maybe can buy from local ebay seller. I have bought some coin battery for watches from a local ebay seller, he also got sell CR2016 battery.

I tot CR2032 and CR2016 is same same 3V?

 

[albertlee]

I tot CR2032 and CR2016 is same same 3V?

If I'm not wrong, the only difference is the battery thickness.

Thicker, so it has more capacity. The thickness can tell from the name btw. 2032 - 20mm dia x 3.2mm / 2016 - 20mm dia x 1.6mm

Typical capacity:
CR2032 - 240mAh
CR2032 - 90mAh

Only suggested replacing it directly if it's not soldered...cos I bo skill and tools, lol. and looking at pics with the transparent heatshrink tubing, didn't look soldered.

Found a page with some DIY tips, they replaced it without soldering. I guess if want to be extra kiasu, that's less secure than soldering cos the tape might loosen over time if the adhesive weakens. But for non-mission critical personal comp, wrap as tight as you can should be okay. At most just re-do.

i DIY-ed for my old old laptop.
remove the black plastic and gently use a small scraper to remove the small solder points between the battery and +/- points.
then put it back together using those high temp 3M black tape (those use for electrical wiring kind)
and it works.
cheap and good alternative.

CR2032 Nomenclature

C - Lithium
R - Round
20 - 20mm diameter
32 - 32mm thickness

[Silverback84]

i use CR2032 too

 

[lccpor123]

Okay guys update:

Managed to get CR2025 since UNICELL does not have.

Installed in laptop now working fine.

Thanks for the answers and help

2032 in red is 3.2mm thick. not 32mm which is close to (31.75) 1.25 inch thick, way too thick as CMOS battery.

So as long as it is 3V button type lithium is okay?

In future, just replace with any 3V button cell lithium battery. Any one from 2032, 2025 or 2016 as long as enough space in the battery compartment.

I don't bother to go all the way to SLS to get these batteries, I'll grab any available 20mm series and solder it using the wires salvage from the flatted battery and wrap it with 20mm heat shrink.

Just before you solder the wires to the button cell, use a razor blade or needle file to file away the plating layer on both the positive (top) and negative (bottom) node of the cell and expose the bare copper base. Solder using a 60W iron and don't overheat the cell while soldering, a 2 to 3mm bare patch is enough for the solder to hold the wires to the cell. Wrap it up using heat shrink (if available), else use any PVC insulation tape will do.

Okay will try DIYing the CMOS battery

Thanks for advice
