Well packaged, well made batteries for use with game cartridges'.
I have 8-10 Gameboy/Gameboy Color games with dead batteries and I wanted to replace those so I can save my games! These are exactly what I needed. They fit great, seem well made and VERY easy to install thanks to the tabs. They're small so you may want to use tweezers when installing them! Overall, this package is a great value for the money. Only time will tell if the battery life holds up but so far, so good!

Easy replacement for Game Boy Color cartridge battery!!!
Perfect CR1616 size replacement with tabs. I was able to replace the battery in one of my game boy color cartridges by soldering in a new one. I wish I had known about this earlier. Make sure you look up what size is needed for your game. Pokemon Yellow required CR1616.

They work
Checked with multi-meter. Batteries have a 3.33V charge, which is within the spec for a 3V CR1616 battery. I use these in Game Boy/Game Boy Color games as a replacement battery for saving. Only time will tell if they are quality, but first impressions are all pointing in the right direction.
