X10 Game Boy Save Battery CR2025 Tabs Pokemon Blue Crystal Gold Silver & Red

Do your games no longer save? If this is the case then you need a new save battery.
This is for 10 CR2025 coin cell batteries with tabs.
These are the exact same batteries used in Pokémon Blue, Crystal, Gold, Silver and Red Games plus many other Game Boy games.
All Game Boy games that use battery back-ups use either CR2025 or CR1616 coin cell batteries. To determine which one your game uses open them up and measure the diameter of the battery. A CR2025 coin cell battery is 20mm wide while a CR1616 coin cell battery is 16mm wide.
You will need a soldering iron to install these. In order to open your game cartridges you will need a security bit. GameBoy Original and GameBoy Color games use a 3.8mm nutsetter security bit while GameBoy Advance games use a triwing security bit.
