Does an Ignition Interlock Drain My Car Battery?

Does an Ignition Interlock drain my car battery? You may have researched this question and seen a few sources say either yes or no. So, what is the correct answer? Here’s the truth behind whether an Ignition Interlock Device drains your car’s battery.

Ignition Interlocks Work With, Not Against, Your Car’s Battery

Many accessories with your vehicle draw a minimal amount of electricity, such as your clock, radio, the internal memory of your engine computers, or even cables such as your cellphone charger. Leaving your headlights on overnight or not closing your trunk completely will cause your car’s battery to drain much more than any electrical accessory!

When you have an Ignition Interlock installed into your electrical system, the device will draw a tiny amount of power from your car’s battery as well, but it is never in such an amount that would drain your car battery totally. If your vehicle’s battery does die, it is typically because of an old battery or a defective alternator. If this occurs, you may need to visit a mechanic. Read our blog to find out the process of taking your car to a mechanic if you have an Ignition Interlock.

Ignition Interlocks draw less than ¼ of an amp while the vehicle is not operating, and ½ of an amp when it is preparing for a breath test. This is a very minimal amount compared to your car’s stereo, or clock!

Use Your Vehicle on a Consistent Basis

Your car may not start if you do not use it for a while, too. Your accessories are constantly using your car’s battery, so if you are not charging the battery by not starting your car, your battery will likely die. Make sure you are using your vehicle to maintain its battery power!

Checking Your Current Battery Voltage with the Ignition Interlock

With Smart Start, clients have an easy way to check their car battery’s current voltage right on their Ignition Interlock screen.

To check your car battery’s voltage, press the pound or # sign, then the number 2 on your device’s keypad.

Is your battery below 12 volts? You may want to charge or change your car battery.
