The battery is a standard CR2032 battery. It is not rechargeable, or unique, and is replaceable, with some extended [[MSI Motherboard CMOS Battery Obsolescence#Workarounds\|effort]].

	Due to this misleading language in the manual and obfuscated location of the battery, it is a blatant attempt to lead consumers to believe that the mainboard is obsolete when the battery dies. Circumventing this requires service from an experienced technician, leading to more device turnover. CMOS battery removal has always simply required pressing a clearly marked tab and removing the old battery out of the standardized component clip slot on the face of the motherboard, and, if needed, putting a replacement one in its place. There is no reason to have changed this.
