These Acer "Cloudbooks" use a capacitor backed CMOS RAM, with a reference BIOS setting stored in NVRAM. If the machine has problems with saving BIOS settings, it is due to a bad primary battery, as it is held with a supercapacitor on these. I do not see a CMOS battery on the motherboard on this laptop.
The early "CR-48" and "CR-50" Chromebooks often had a CMOS battery, but the newer ones rely on a NVRAM due to how the newer Coreboot BIOSes handle settings changes. The change was made when Google got away from the BIOS fragmentation and standardized on one Coreboot configuration all of the OEMs use.

Sometimes they still have one for date/time maintenance, but the vast majority use a capacitor backed CMOS RAM, and store most of their settings (including management information) in NVRAM.
