CMOS Batteries?

With either the QU or SQ series, is there a CMOS battery we need to worry about replacing? In the iLive we have to replace the CMOS 2032 in the display. The GLD also has a battery that ultimately needs replacing. Has anyone done this with the SQ or QU yet?

@Grimey

There are no CMOS batteries in the Qu, SQ or CQ ranges.
All use non volatile storage for bootloader/firmware/data.

Cheers,
Keith.
