Understanding Why Your Car Battery Dies

Before we dive into the how-to, let’s quickly touch on why car batteries die. This knowledge can help you avoid future dead batteries. The primary culprit is usually draining the battery’s power faster than it can be recharged; this happens when the engine is off but something electrical is still running.

Common reasons include:

Leaving headlights or interior lights on overnight.
A faulty alternator that isn’t recharging the battery properly while you drive.
An old battery that has simply reached the end of its lifespan (most last 3-5 years).
Parasitic drain, where a component continues to draw power even when the car is off.
Extreme temperatures, which can stress the battery.

An ignition interlock device like Intoxalock requires a small amount of power to operate, but it’s designed to be very efficient and typically doesn’t cause a dead battery on its own unless the battery is already weak or there are other electrical issues.

What is an Intoxalock Device?

An Intoxalock is an Ignition Interlock Device (IID) that requires a person to blow into it to provide a breath sample before they can start their car. This is often a requirement from the court or DMV. It’s designed to ensure the driver is sober. The device itself is relatively small and connects to your car’s ignition system. It requires a small amount of power to run, but it’s generally not the cause of a dead battery.

How Intoxalock Interacts with Jump Starting

The good news is that an Intoxalock device does not complicate the traditional jump-starting process. When your car battery is dead, the Intoxalock will not function, but it will not prevent you from receiving a jump-start. The key is to follow the standard jump-starting procedure carefully. Your Intoxalock unit needs a healthy battery to power up and function correctly, so jump-starting it is just like jump-starting any other car—with a few extra steps to ensure safety with the device.

Essential Tools and Preparations

Before you start, make sure you have the necessary items and are in a safe location. Safety is always our top priority.

What You’ll Need:

Jumper Cables: Ensure yours are in good condition, with no frayed wires. A 10- or 12-foot set is usually sufficient.
Another Vehicle: You’ll need a car with a working battery to provide the jump.
Gloves and Safety Glasses: Protect yourself from battery acid and sparks.
Owner’s Manuals: For both your vehicle and the vehicle providing the jump. These can indicate specific battery terminal locations or safety precautions.
A Safe Location: Ensure both cars are parked on a level surface, away from traffic, and preferably in a well-ventilated area.

Safety First! Pre-Jump Start Checklist:

Park Safely: Position the working car close enough so the jumper cables can reach both batteries comfortably, but not so close that the vehicles touch. Turn off both cars and engage their parking brakes.
Open Hoods: Locate the batteries in both vehicles. Refer to your owner’s manuals if you’re unsure where they are.
Check for Damage: Inspect both batteries for any cracks or leaks. If a battery is damaged, do not attempt to jump-start it.
Intoxalock Status: Ensure your Intoxalock device is mounted correctly and in its usual place. It will likely appear inactive or show an error due to the dead battery.

Step-by-Step Guide: How to Jump Start a Car with Intoxalock

Now that you’re prepared, let’s get to the core of it. Remember to work methodically. This guide mirrors the standard jump-start process, with considerations for your Intoxalock.

Step 1: Prepare the Cables

Lay out your jumper cables, ensuring the red (positive) and black (negative) clamps are not touching each other or any metal parts of the cars until instructed.

Step 2: Connect the First Red Clamp

Attach one of the red (positive) clamps to the positive (+) terminal of the dead battery. The positive terminal is usually marked with a “+” sign and might be covered by a red plastic cap.

Step 3: Connect the Second Red Clamp

Attach the other red (positive) clamp to the positive (+) terminal of the good battery in the working vehicle.

Step 4: Connect the First Black Clamp

Attach one of the black (negative) clamps to the negative (-) terminal of the good battery. This terminal is usually marked with a “-” sign.

Step 5: Connect the Second Black Clamp (Grounding)

This is a crucial step for safety. Attach the second black (negative) clamp to an unpainted, unmoving metal surface on the engine block or chassis of the car with the dead battery. This is called the grounding point. Do NOT attach it to the negative terminal of the dead battery, as this can create sparks that could ignite hydrogen gas emitted from the battery.

A good grounding point is typically a sturdy bracket or a bolt on the engine. If you’re unsure, consult your owner’s manual or a reliable automotive resource like NHTSA for guidance on safe grounding locations for your specific vehicle model.

Step 6: Start the Working Car

Start the engine of the car with the good battery. Let it run for about 5-10 minutes. This allows the good battery to send some charge to the dead battery.

Step 7: Attempt to Start Your Car

Now, try to start your car. It might take a few seconds longer than usual. If it starts, great! If not, wait another 5 minutes with the working car still running and try again. If it still doesn’t start after a couple of attempts, there might be a more serious issue than just a dead battery.

Step 8: Disconnect the Cables (In Reverse Order)

Once your car has started and is running smoothly, it’s time to disconnect the jumper cables. This must be done in the exact reverse order of how you connected them to prevent sparks and potential damage.

Disconnect the black (negative) clamp from the grounding point on your car.
Disconnect the black (negative) clamp from the good battery.
Disconnect the red (positive) clamp from the good battery.
Disconnect the red (positive) clamp from your car’s battery.

Be careful not to let any of the clamps touch grounded metal or each other during this process.

Step 9: Keep Your Car Running

After disconnecting the cables, let your car run for at least 15-20 minutes. If possible, take it for a drive. This will allow your car’s alternator to recharge the battery properly. If you turn it off too soon, you might find yourself with another dead battery!

What to Do If Your Car Still Won’t Start

If, after following these steps, your car still refuses to start, the issue might be more complex than a simple dead battery. Here are a few possibilities:

Faulty Alternator: If your alternator isn’t charging the battery, it will die again soon after a jump-start.
Bad Battery: The battery might be completely beyond its lifespan and unable to hold a charge.
Starter Issues: The car’s starter motor might be failing.
Fuel or Ignition Problems: The issue could be with the fuel delivery or ignition system, not the battery at all.
Intoxalock Malfunction (Rare): While unlikely to prevent a jump start, a severe malfunction could theoretically cause electrical issues.

In these scenarios, it’s best to call for professional roadside assistance or a mechanic. Trying to force a start repeatedly can sometimes cause further damage.

Maintaining Your Car’s Battery and Intoxalock

Preventing a dead battery is always better than dealing with one. Here are some tips to keep your battery healthy and your Intoxalock system ready to go:

Regular Testing: Many auto parts stores offer free battery testing. Get yours checked periodically, especially if it’s over three years old.
Minimize Drain: Make a habit of turning off headlights, interior lights, and the radio before turning off the engine.
Check for Corrosion: Keep battery terminals clean and free from corrosion. You can use a wire brush and a mixture of baking soda and water for cleaning.
Drive Regularly: Short trips don’t always give the alternator enough time to fully recharge the battery. Try to take your car for longer drives at least once a week.
Intoxalock Calibration: Ensure your Intoxalock device is being calibrated and serviced according to the manufacturer’s and your monitoring agency’s schedule. A properly functioning device is essential.
