This listing is for one CR2025 lithium coin cell batteries with generic tabs, fits any gameboy and gameboy color cartridge, suitable as a replacement internal save battery.
For larger quantities please check my other items, i sell 1x, 2x, 5x 10x and 20x with lower prices per unit as the quantity goes up, and for more i can adjust my prices even lower


Description:
I have personally confirmed the quality of the coin cells, they both solder well and quickly which is ideal when tampering with old circuitry, also they fit all 3 of my own expired games fine, being Pokemon yellow, Zelda links awakening and Pokemon Red.
Cell body is solder and corrosion resistant high grade stainless steel (cant corrode and wont form any accidental or on purpose solder bridges), cell chemistry is Lithium and the battery is designed for long period low drain application i.e is designed for maintaining volatile memory. Cell capacity is 150mAh and the voltage is 3V Solder tabs are spot welded onto the steel forming a steel on tinned steel bond so no amount of time will cause the tabs to release or break. Life expectancy is likely to exceed the original batteries and then some. For pokemon games this is upwards of 20-25 years. The tab design is dual purposed and is compatible with a clip mechanism for a solder-less connection in some applications.
Most GBC games use CR1616 cells, there is no problem in using larger cells however, only when replacing 2025s with 1616s in systems using larger save ram needing larger batteries. as PCB and cases are identical for all games, wether or not a 2025 will fit in a 1616 game is not an issue. If unsure, always use 2025s. If replacing GBA clock batteries, 1616 is advised instead but 2025s can be made to fit, sometimes. the cost per cell will be the same for 2025s and 1616s

The current batch of batteries was manufactured to order, dated as, August - 2023.
