Can a Car Battery Die with Interlock?

No, a car battery can’t die with a car interlock. Like all other automotive accessories, the car interlock consumes power and electricity from the battery. Still, unlike other accessories, the interlock’s electricity draw is minimal, so the battery’s impact may not even be noticeable.

If, by chance, your automobile battery fails while the interlock is set up or in use, it might not be related in the least to the interlock. As a result of the dead battery that is supposed to power the interlock, it will also not function.

Possible Reasons Why Car Battery Dies With Interlock:

1. Overcharging:

What Happens If A Car Battery Died With An Interlock?

In my own experience, I’ve come to understand that if an interlock causes a car battery to die, the issue may or may not be directly linked to the interlock’s electrical consumption.

Interlocks do draw power from the battery, whether for a breath test or during idle periods. From my observations, the power consumption while the car is stationary is typically lower than during operation. However, a malfunctioning interlock could potentially exceed the necessary power draw, gradually draining the battery.

I’ve found that the probability of battery discharge increases significantly if the interlock is faulty or incompatible. Over time, batteries naturally degrade in performance, adding to the likelihood of issues.

In a situation where you attempt to start the car after taking a breath test, a weakened battery may pose challenges. It’s easy to assume the interlock is responsible for the battery failure, especially if you weren’t acquainted with the battery’s condition before.

What To Do If A Car Battery Died With An Interlock?

There is no way to start the engine if the automobile battery dies while the ignition switch is locked. It occurs as a result of the car battery’s low voltage. In my experience, if you find yourself in a situation where a car battery has died with an interlock, here are some steps you can take:

  • You should first try charging or jump-starting the battery to check if the issue still exists. If it doesn’t, the battery was likely low when you activated the interlock, and it may have just used up all of its power.
  • The car battery has a problem and must be considered if it stops working after being recharged.
  • To determine whether the battery and interlock are in excellent shape or need to be replaced or repaired, you should inspect them both.
  • Make sure the wiring is done correctly.
  • Ensure you only leave the car running when you are inside or idle for an extended period without recharging the battery.

When you employ the interlock, any of these things or more could result in a car dying. While idling, the battery might not charge by itself.
