The National FS-CR1008S is a data cartridge used to backup National Japanese word processors, firmware data and also the data of the Ricoh RP-5C01 clock chip on the following MSX2 National computers:

The data are saved on a 8kB SRAM (Static RAM) and a little battery preserves them when the computer is off.

A switch on top of cartridge allows to enable or disable "Memory Power", so you can disable the cartridge SRAM when you prefer to use the SRAM built in the FS-4500, FS-4600F and FS-4700.

Note: It can probably also be used with the Panasonic FS-PW1 printer, but it needs to be checked.
