While you may not need it, you can purchase another CMOS battery. Shipped with your system, in the box, will be an extra CMOS battery. If you look at any motherboard, you'll see a button-shaped battery on it. If that dies (somehow), then saving some settings for your motherboard may prove difficult. If you get any warnings about a CMOS battery being dead, or if you want a spare battery on hand, then purchase this option! Please note we won't be actually installing a new one, as the one that comes with every motherboard is fully functional, and usually does not go bad for at least 5 years. But if your board just so happens to need a replacement, then...well...we have a few!
Battery expiration date: 2023
