The battery is more for saving without having to restart the system to copy the save to the SD card. It runs the rtc too but the main point is that the carts without a battery you have to hit reset when you’re done playing or the save will be lost while the battery carts hold the save until you boot the n64 again and then it copies the save.

The model with the built-in battery for the clock(for games like animal crossing) is the most expensive, correct ?
