Is it time to change my car's battery?

Is there a problem with the battery in my 2017 Discovery? It's losing voltage when left parked for two weeks.

That sounds pretty typical. A modern car is full of energy-sapping electronics and really needs driving at least once a week to keep the battery in good order. If your Discovery still has its original battery, it might be time to change it anyway.
