Why are remote starters bad for your car?
“Your engine works its hardest when the weather is cold, and nothing will warm it up more efficiently than driving it. When you remote-start your vehicle while you're still getting ready for work, you greatly prolong the warm-up period. And over time, all of this unnecessary strain on your engine can be damaging.”

Introduction
Background
- Definitions
Cold Cranking Amps (CCA) 1. Cold cranking amperes (CCA) is the amount of current a battery can provide at 0 F (−18 C). (Source) Parasitic Current Drain (iP) 1. Parasitic current drain can be defined as any electrical device that draws electric current when the ignition key is turned off. In … - Battery Capacity Versus Temperature
Figure 2 shows the impact of temperature on the capacity of a lead-acid traction battery.
Analysis
- Figure 5 shows my analysis of the battery capacity. What I calculated is that the battery’s capacity has reduced by ~75%. This results in a large decrease in the cranking amps available (justification in a later post) and results in slow or no cranking when attempting to start the car.
Conclusion
- I am afraid that an additional parasitic battery load of 70 mA is enough to drain the battery sufficiently after five days to make starting difficult or impossible. This reminds me of a battery problem I had in my youth where a glove compartment light did not turn off and would slowly drain my battery. I could fix the light problem, but the remote starter must draw current to detec…
