Get out the magnifying glass. Sometimes the battery type is imprinted on the battery holder or silk screened onto the motherboard.

However, going to the Compaq website and looking up Presario 5400 it appears that it is a 3 volt Lithium battery, Sony model # CR-2032. Readily available at your local drugstore.

Re: Compaq 5440 cmos battery

Per the manual you need a Compaq RTC Battery 144361-001

ftp://ftp.compaq.com/pub/supportinformation/consumerdocs/MaintServcGd/5423-5465.pdf

The online parts price is a whopping $35.00.

The standard battery used on most motherboards is a 3V lithium CR2032 which costs a few dollars at your local drugstore. There are some fancy batteries used in a few systems which sense when power is supplied and turn themselves off in order to save power and these run around $25. I can't tell from the partnumber. Supposedly your 5440 uses a Gigabyte GA-5SMM motherboard but I can't find any indication of the required battery on their site either.

has a link to an email where you can ask them if they have a CMOS battery for your computer. You might try them.
