FAQ: Why Do I Have To Set My Saturn’s Clock?
If you recently bought a used Sega Saturn, chances are that when you boot the machine up, you will be asked to set the time and date. You probably don’t think much of it the first time, but you will probably become frustrated when you have to reset the date and time EVERY time you start up your Saturn.
Why is your Sega Saturn so forgetful? Most likely this problem is caused by a dead system battery. Don’t worry though, as a Saturn system battery is not expensive at all. I actually sell them for only $0.89 each plus shipping.
Not only will these batteries keep the date and time set, but they will also help your Saturn keep your game saves. So if you are playing a long RPG and save your progress, you won’t have to start over after you turn the system off.
If you want to keep your new system battery in top shape, make sure you play your Saturn at least a little bit every now and then. Just like a car, running it occasionally will help the battery re-charge a bit.
