Sega Saturn Battery help

I recently aquired a Japanese Saturn and as expected it had a dead battery. So I replaced it with the same type and I'm still getting the time and date screen resetting everytime I use it. I have checked the battery is in correctly and made sure it was the right type and I havent just copied someone putting the wrong one in. The battery is a good brand, Energizer.

Is there more issues that can go wrong or is there something else I'm meant to do? any helps appreciated.

The SS uses a CR2032 lithium battery, so if you have one of those then the internal RAM should be backing up your data.

Maybe the battery is not connecting properly, otherwise the only explanation is that something must be damaged.

If you continue to have problems, then it may be better for you to buy a back-up RAM cart or a 4-in-1 Action Replay. You would still have to set the time & date every time you start the system, but at least you will be able to save your games.

It is a CR2032 but I thought my new one was an Alkaline and not a lithium. will that cause an issue? I have a 4 in 1 cart but have yet to save any games as I thought I had to save normally then move the save to the cart. I haven't looked at that area too much as I assumed I couldn't save yet. Plus I have only been playing a few arcade games that I haven't needed to save yet.

Edit - The battery is a lithium.
