This is my second battery for my 2024 Prius

A jump drive gets you going with a dead battery, while a charging strategy keeps the battery from dying.

 

Moreover, especially with a Gen 4/Gen 5 Prius, once the lead–acid battery is fully drained, a jump start is not sufficient to restore it to a partially healthy state, as the battery management system (BMS) will be very confused. You need to manually charge it with a battery maintainer. Otherwise, you will be running it at around 30% capacity. A battery maintainer could perhaps bring it to 70–80% capacity, depending on the damage caused by the full drain.
