Quick question. I need to replace the internal battery in my Dreamcast. Which battery do I need to get? Someone told me it needs to be an LR2023 which I can't find anywhere. Can't I just use a CR2025?

It's some silly rechargeable design so a CR2025 wouldn't work and could possibly leak.

I've been meaning to do this for a while, I even chopped up an old TV remote so that I could have an easy to replace battery tray:

The type of battery is called a ML2032 which is a rechargeable coin cell. People do either replace the battery with a new one with tabs, a coin cell battery holder like in these instructions:

Or with rechargeable AA or AAA's with a holder like b1aCkDeA7h linked.

Couldn't you install a diode so a normal coin cell be used?

Awesome!

Thanks a ton. I had planned to replace it with a holder as well, just like I've been doing with my carts. Too bad the ML2032 seems to be just as scarce as the LR2032.

I was wondering the same thing.

ML2032 is Maxell's rechargeable code, if you search for LIR2032 you'll find more options. Normally I carry them but I just sold my last ones today and the restock won't be in for a week or so.

Thanks for the info! Let me know when you have some back in stock and I'll buy them from you.
