12 Pack CR2025 Battery, CR2025 3V Button Cell Lithium Game Batteries with Solder Tabs for NES, SNES, Gameboy and Sega Genesis Cartridge Battery Replacement

Good value

Perfect fit and function on Gen 2 pokemon and a few other gameboy games I used them on. Be wary of force fitting a cartridge back together if you use them for Gen 3 Pokemon.

Any pokemon game with a battery in it, use these to double the life of you save battery. Get these instead of the CR1616 and get double the life! They will work in All Pokemon games including Emerald,Sapphire , and Ruby.

These worked to replace my old gameboy game batteries just fine.

Used this to replace some game boy game batteries, I got the battery number from the battery in the game and had no issues.Keep in mind some newer games take a slightly smaller battery. Check first before buying.

Installation was straightforward and all the batteries were charged. My old Pokémon games can now save again. It would have been 5 stars, but I only received 11 in the pack, when it should have been 12.

These are a bit smaller than the original, but they still work great, I haven't had any issues with gameplay functionality or saving after replacing with these batteries.

Long story short I found a original copy of Pokemon Silver in a trash can years ago that couldn't save progress. I finally got around to getting this pack of batteries to fix it along with a few others. It saves the progress now, so no more starting over every time I turn on the Gameboy.
