How long does it take for a car battery to die completely?

Answers

A car battery's lifespan before complete discharge varies greatly but can range from hours to weeks depending on the battery's condition, temperature, and electrical load.

From a purely scientific perspective, the time until complete discharge is governed by a complex interplay of electrochemical processes, governed by the Peukert equation and impacted by both internal resistance and external load conditions. Ambient temperature, a significant variable, exponentially affects reaction rates. Thus, a precise prediction requires detailed knowledge of the battery's specifications, its current state of health (including sulfation levels and internal impedance), and the precise electrical load profile imposed upon it. In practice, this makes precise prediction exceptionally difficult. However, a reasonable estimate can be made via empirical measurements, monitoring battery voltage and current draw over a defined period.
