What Happens When I Remove the BIOS Battery in an Ion Xe?


My console is being transported via air and the BIOS (CMOS) battery must be removed during transport. 


The BIOS (CMOS) battery stores persistent memory for BIOS and the Date/Time/Location settings for your console. Removing this battery and putting it back in will cause these features to reset to defaults. Unless otherwise altered by an end user, the BIOS settings on your console are also the default settings. 


The BIOS (CMOS) battery does not store data for the Show File Archive, however it is highly recommended that the Show File Archive is backed up onto an external drive before the console is transported.  

Replacement Battery

CR2032 batteries are commonly available.  CR2032 can be sourced online (search for "CMOS battery 2032").  It is not possible to replace just the battery part of the CR2032W as they are manufactured not to come apart.

Note that CR2032W is not a standardised part, and batteries with that description may have a subtly different connector, and/or reversed polarity

CR2032W may be available from an ETC Dealer; the ETC Part# is BT161.

Please check your console and purchase the appropriate style of replacement battery.
