Check if removing the CMOS battery affects your motherboard's long-term storage.
Hi, your question is clear. You have some old motherboards with LGA775 and 1366 sockets that you want to store safely for a while. Regarding the CMOS battery, it’s generally safe to leave it in unless you plan to use the board again soon. Removing it won’t affect the BIOS settings much over time, but keeping it might help preserve certain settings. Just ensure the board stays powered during storage if possible. Thank you!
It maintains a small power chip to preserve changes until startup, but prolonged exposure could damage the CMOS battery. Best to take the battery out for extended storage. Keep a box of CR2032 handy.
It will fully erase your BIOS to the factory defaults. Anything else is not recommended. If you keep it on while powered on, it retains your saved settings but poses a significant risk of damage or failure.
