The main purpose of button batteries in handheld game consoles
Button batteries are widely used in modern game cartridges, modern game console motherboards, and many newer handheld game consoles. The main uses are:
Saving game saves:
When the console's main power source is removed or exhausted, the button battery provides a weak, continuous power to a special memory chip on the motherboard. This chip is responsible for storing key information such as your game progress, settings, time and date. Without this button battery, once the main power is disconnected, your saves will be lost.
Maintaining the real-time clock: Some newer or special-purpose game consoles have a built-in real-time clock. The button battery is responsible for maintaining the clock when the main power is disconnected, ensuring that the in-game clock system (such as the day and night cycle or event triggering in some games) remains accurate after the console is turned on.
Why use a coin cell battery?
Small size: Ideal for integration into a circuit board or cartridge without taking up too much space.
Low self-discharge: Low self-discharge rate means the battery can retain power for years even when not in use.Stable voltage output: Provides stable voltage.
Meets low power requirements: The current required to power an SRAM chip and real-time clock is in the microampere range, which is perfectly adequate for a coin cell battery.
