MSI Mainboard CMOS CR2032 batteries are no longer contained within a standard easily accessible clip-mount holder. Instead the CMOS battery is hidden beneath the Voltage Regulator Module (VRM) heatsink assembly, and is affixed to the mainboard via a lead, and mounted with adhesives and shrink-wrap plastic.<ref>{{Cite web |date=2022-04-15 |title=MSI Pro B660M-A CMOS battery location? |url=https://forum-en.msi.com/index.php?threads/msi-pro-b660m-a-cmos-battery-location.374514/ |url-status=live |archive-url=https://web.archivep75mbjunhxc6x4j5mwjmomyxb573v42baldlqu56ruil2oiad.onion/web/20260302095843/https://forum-en.msi.com/index.php?threads/msi-pro-b660m-a-cmos-battery-location.374514/ |archive-date=2026-03-02 |access-date=2026-03-02 |website=MSI Global English Forum}}</ref><ref>{{Cite web |date=2023-11-29 |title=Where is the location of CMOS battery on this motherboard? |url=https://www.msi.com/faq/9918 |url-status=live |access-date=2026-03-02 |website=MSI Global}}</ref> Some of the lower-end tier models of MSI motherboard still have a clip-mount, but it is blocked by heatsinks (that are not part of the VRM assembly).

This is False. The battery is a standard CR2032 battery. It is not rechargeable, or unique, and is replaceable, with some extended effort. | This is False. The battery is a standard CR2032 battery. It is not rechargeable, or unique, and is replaceable, with some extended effort. | ||

While the battery remains a standard CR2032 coin battery, and the mounting mechanism is not completely inaccessible, due to this misleading language in the manual and obfuscated location of the battery, it is a blatant attempt to make the mainboard obsolete when the battery dies. Replacement requires service from an experienced technician, leading to more device turnover. For 40 years of mainboard design, replacing a CMOS battery has required locating the battery on the face of the mainboard, pressing a clearly marked tab and removing the old battery out of the standardized component clip slot, and putting a replacement one in its place. There is no reason to have changed this. | While the battery remains a standard CR2032 coin battery, and the mounting mechanism is not completely inaccessible, due to this misleading language in the manual and obfuscated location of the battery, it is a blatant attempt to make the mainboard obsolete when the battery dies.
