Replace the Battery in your Game Cartridge! **56k warning**

[def_K]

You can buy them online (part number P223-ND at digikey.com) if you want to pay a lot for shipping.

So i checked the link out but it comes up with a BR 2032 battery instead of a CR 2032...
judging by the picture on the site, it looks like it would still work but im not sure.
I searched for the part P245-ND instead and it looks just like the battery in the red version cart in the picture master kirby posted at the beginning of this thread, but the tabs are in the wrong positions. Could the tabs somehow rotate?

Yep, it is a BR battery. Not sure about the position of the tabs, but as far as I know, CR and BR are both fine, they are just designed for slightly different kinds of circuits. Either should work in this case. A CR battery's voltage drops uniformly over time whereas BR maintains a pretty steady voltage over its life, but then drops suddenly at the end of its life. Check out the very bottom of this page: http://www.swcomputingservices.com/batteryorder.html.

I used the BR2032 from digikey and my games seem to be working fine so far.

I would like to thank you as well for your detailed guide as it is the only one that is actually useful on the internet. I started the process but i'm having a hard time finding a battery with tabs, so i guess i'll buy one from Digi-Key.
