X10 CR1616 + X10 CR2025 Save Game Batteries Tabs Covers All Pokemon Games

Do your games no longer save? If this is the case then you need a new save battery.
This is for 10 CR1616 & 10 CR2025 coin cell batteries with tabs.
These are the exact same batteries used in all 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.
