Hi,
The RTC (Real Time Clock) battery, (aka cmos battery or BIOS battery) is a Maxell ML1220 T10 rechargeable Lithium battery (supplier example only) that is soldered directly onto the motherboard.
Here's an image from a LA-5751P motherboard (Lenovo Z460), showing where it is located on the board. The battery's motherboard component ID is JRTC (see red arrow in image)

If replacing the battery, check the polarity of the battery leads to make sure that it is installed the correct way
