If I had to guess its the CMOS battery, it keeps BIOS settings and your clock running while the computer is off. Nonvolatile BIOS memory

It sounds like you are referring to a type of battery. It is used in calculators, automobile remotes, some kinds of small lights, and other devices. What, specifically, is your question?

Sony pcvrx514 cmos battery part number


Hi
This appears to be a desktop machine, and most motherboards use a CR2032 type coin style battery.
If you can get the battery off the motherboard being careful not to damage any part of the motherboard then the type and voltage of the battery is usually engraved on the metal case.
If this not the case then compare the physical dimensions - very carefully - between your battery and a CR2032 and if they correspond try the CR2032 before looking elsewhere.
Cheers

What battery does an OXO small kitchen timer need?


battery-oxo-small-kitchen-timer-need-b1enchklgluxhkaxylqpxcgq-1-0.jpg
I'm assuming you're referring to OXO's Magnetic Digital Timer model #1127980. The instructions require a CR2032 (coin-type) battery which is accessed by gently prying the battery cover off with a coin. You can download the instruction booklet here:

How to change battery on asrock k7s8x motherboard


A coin-cell battery (CR2032) usually powers the real-time clock and CMOS memory. The battery is 3 Volts, 3/4" in diameter and has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery.
Just open the desktop, locate the CMOS (Coincell) and remove using screw driver. Replace the battery with CR2032 or an equivalent one.The following brands are used interchangeably for this item: Energizer (ECR2032), Duracell, Panasonic, Eveready, and 3M etc, which can be purchased from any local electronics store.

GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

Battery Replacement


Use a safety pin to pry it up. It is supposed to be in tight to keep it from popping out in a jolt. Also check to see if there is any metal clip on top holding it in place. If there is, make sure you pry up on the opposite side of the battery.

Coin cell backup battery


No the coin cell backup battery is not rechargeable. If the MobilePro 900 back up battery is low it should be replaced. The battery is a CR2032 coin-cell battery, which is very common and can be purchased at most department and drug stores. Refer to section 1-7 of the “MobilePro 900 Handheld PC’s User’s Guide” for detailed replacement instructions.
