Helping with choosing a replacement battery plz

[fredyyy]

so I was searching online, and it seems there are different type of batteries. Some are rechargeable others are not. I opened the console, to see which type I have, but I didn't see any indication of the model number of the battery I have.

So my question:

1- how do I know the model number I have? all I saw it's 3V rechargeable battery
2- which replacement battery do you guys suggest me buying?

Thank you in advance

The 3 volts is totally fine for the project since that's what the Dreamcast uses for it. However you need to get a specific battery type. What is recommended is the LIR2032 cell battery. Just start doing your research on batteries because most of them you will find will work for the job. Just stay away from the shady dealers and any of those that were salvaged from other equipment since those may show some kind of aging from being previously used in use or may not even hold a charge at all. The newer the better.

Thank you very much! I found one seller on ebay has this:
"Sega Dremcast Console Memory Battery CMOS Backup (LIR2032 Rechargeable)". I guess I will go with this
