My RED cart battery died a long time ago. Save being gone is expected. I’ve replaced the battery and played for probably 15 in game hours. Luckily I backed up the save on my pc using an adapter. I turned on the game one day and the save in the cart died. I replaced the battery and it too died the next day. I changed the battery again and kept the device off for 1 week, still saves. Kept the thing off for 3-4 weeks and the thing is dead again. Voltage of the 2025 (i think is 3) 0.7. How is the cartridge dying while the gameboy is off? I put another battery from the same pack I got it from into a BLUE version and it works fine 10+ weeks after installation. What am i missing?
CR2025 Batteries are preferred
