Acer CMOS Battery

Hey Guys,

So recently I have had a friends computer's CMOS battery die on me. It is an Acer 5920 and I have already ripped it open only to find the battery with no writing on it

So after contacting Acer support they have told me so give them $200 to fix it or $100 to talk on the phone for half an hour... So Acer techsupport sucks and I or anyone I buy computers for will not be getting an Acer anymore

So if anyone knows the CMOS battery model I would most appreciate it I know it is a Varta something.... but its hard to ebay a something

Thanks Guys!

 

Argh am I really going to have to rip apart the entire thing??? Can anyone out there help???

 

CR2032? maybe. That's the standard cmos battery in most computers.

 

If it's a coin cell the number is related to the size. Is so measure it and compare to standard sizes available.
CR2032 as Lucida mentions is 20mm diameter and 3.2mm depth.
Post a picture of it if it's some other shape

 

as long as its 3v , its oke you can use any batery . its just the size that maters becuase of cover fitting , but i thing you dont have to worry about that .
MAKE SURE ITS ISOLATED !!!!!!!!!!!!!!!!!!!!

 

... thats just it I don't know if it is a 3V. I was hoping someone had some idea. I know it is a Varta, and I know it is a Lithium (not Lithium Ion).

 

What does it say on the battery... any numbers, letters etc
What shape is it ?

It could be a rechargeable lithium,

in which case you must NOT fit an ordinary one.

Edit... also found this... read it all...

Lol I don't want to rip the laptop apart again to find the numbers, I thought I wrote them down the first time

And as for rechargeable it would have to be a Lithium Ion, and it is merely a Lithium battery cause I remember researching that when I first ripped it apart.

Thanks for the help

 

There all 3v and like 90% also works with 5v but 3v is standerd always use this , 3v will never be bad

 

did you have any luck finding the type of the battery?

I'm having the same problem with my 5920g and I'm looking for a replacement Cmos battery.

thx

 

It is most likely a CR2032 3volt at least that's what desktop use, as long as it is 3volt the size does not really matter, it just affects how long the battery lasts, just make sure you get the polarity right.

 

so what you're saying is that every kind of round 3v battery should work on any laptop motherboard? is there no difference with desktop cmos batteries?

Format: 20mm (diameter). Isn't that too big to put in a laptop?

that would be awesome

 

Any of the 3 volt lithium battery s should work, just find one that fits.

The service manual for the 5920g is in the link below it might help.

Thank you for your help.

I'll buy one of those batteries and open my laptop to replace it.

 

Just make sure you cover it in electrical tape so it does not short out on anything.

 

I opened the whole thing yesterday, just to find out the type of CMOS battery.

I'll order one next week, but I don't really know how to fit it in the special casing.

in my pictures you can see the type of the battery. Probably the only place on the internet where you can find out (I also posted it on another forum)

the only thing that bothers me is that I measured the voltage of the CMOS battery and it still said 3,2 volt... But a friend of mine told me that this isn't conclusive to tell if a battery still works or not

 

The ML 1220 appears to be an rechargeable battery, so you will need to replace it with a rechargeable battery, not a standard lithium no-rechargeable as i previously recommended.
