I’ve searched for the past half hour and can’t seem to find any information and swapping out the SRAM battery. I’m interested in grabbing a used Wario Land but the guy has told me that it no longer saves.

Does anyone have a guide for doing a swap?
Can anyone tell me what type of battery to buy?
Do the batteries have tabs on them?

Thanks!

The battery is a CR1616, spot-welded to the tabs.

I put a new one in my Wario Land a few years back. I de-soldered the tabs (with battery attached), then used a blade to get the old battery free. Then I soldered the tabs back in place.

Next I slotted the new battery between the tabs and closed everything back up – I didn’t bother using anything else to secure the battery as it seemed to stay put just fine. And It still works, so yay me.
