A: Either your battery is due for replacement ...

Either your battery is due for replacement or you have a parasitic draw somewhere. A draw can be found by placing an ammeter in series with the negative battery cable. If excessive current draw is found, the cause of the draw must be determined. A trained technician, such as one from YourMechanic, will be able to diagnose and repair this problem for you.
