That is the clock chip backup for the time display. It is a rechargable cell that is soldered in. To replace it you will have to remove the circuit board.
This begs the question... do you really care about the time display?
If your rig is loseing its menu setting and memory frequencies you have a more serious issue.

?All of the CPU¡¯s memory is backed up by an EE- PROM
(Electronically-Erasable Programmable Read-Only Memory). All
data you set, such as VFO, memory, set mode contents, etc.
are stored in this EEPROM. There is no internal lithium
battery.
