Introduction
If you find your Game Boy experiencing save game issues, where progress is lost or becomes intermittent, it may be time to replace the internal battery.
The internal battery within Game Boy cartridges serves a crucial role in preserving your game saves. Over time, these batteries degrade, potentially leading to data loss.
Before using this guide, inspect the battery to test the voltage with a multimeter. Typically, if the battery range is not 1 digit over the decimal point when measured with a multimeter, then that is a sign that the battery should be replaced.
