I think you're
still a bit confused.
GBA carts can have either:
- a lithium battery, for running clocks or retaining saved data in a RAM chip when the cart is removed, OR
- a flash/EEPROM chip, which cannot run a clock, but can retain saved data without the need for a battery
Games are incapable of measuring the strength of this battery, aside from "dead" or "alive" (and even then, they base the "dead" status on the absence or corruption of certain data in RAM when you boot the game, not on a direct reading of the battery itself).
The
GBA itself runs on either AA batteries (original GBA) OR an internal rechargeable battery pack (GBA SP and Micro), which is ONLY used to play games, and to retain data in RAM while the system is in sleep mode. Again, games are incapable of measuring this battery; the green/red power LED is handled by circuitry that is completely invisible to the system. The GBA has
no other internal batteries for running clocks or any other nonsense.
Do you understand now?
Also, cartridge batteries can't just be "replaced by anyone" with a screwdriver; they use specially sized batteries with tabs welded on, which are soldered directly to the PCB. You'd need both a suitable replacement battery and some decent soldering skills to replace one, which is something not just "anyone" can do.
