This is the SMD version of PRT-07948, which is the unit we like to use as RTC backup and SRAM backup for GPS units. Holds battery in place with friction. The metal housing connects to the positive side of the battery and the PCB pad underneath is connected to the negative side.

Jargon buster

Plain-language definitions for the technical terms used above.

GPS: The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
PCB: A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
RTC: A Real-Time Clock keeps track of time even when the main processor is asleep or powered down, usually with a small backup battery. It matters for data logging and tracking projects that need accurate timestamps.
SRAM: Fast temporary memory used by a processor while a program is running. More SRAM helps with projects that handle larger data buffers, networking, displays, or more complex code.
