2nd Gen Where to get a replacement battery pak?

[billionbucks25]

My friend has a friend that has pokemon gold. But now it won't save properly. I know this is because you need to replace the battery pak but that was years ago...where can you find it now?

Any CR2032 battery will work, although the original is a CR2025.

You should be able to get them anywhere that sells batteries, getting ones with tabs should be easily found on eBay.

You CAN just use tape.
