Can A Drill Battery Start A Car?- How I Did It!

A dead car battery refers to a battery that is completely discharged and not able to deliver the required voltage (12.6V) and current (180-230 amps) needed to start a car or power any of its electrical components. A dead battery can not be used to power up the car. In order to fix this you should jump it using a DIY method.

You can follow the below method to jumpstart the car battery using the drill battery.

  1. Check the car battery condition
  2. Take a 12V or 18V fully charged drill battery with 5-6Ah
  3. Connect similar terminals together
  4. Wait 5 -10 mins.
  5. Power up the vehicle

What is the Required Charge, Voltage and Current to Start a Car?

The car battery charge should be more than 40% of its total charge to start a car.

The required voltage in the car battery to start a car is 12.6 volts. This is the usual voltage of a fully charged car battery at rest. However, during the starting of the vehicle, the voltage can drop to as low as 9.6 volts briefly. If the voltage drops below this, it might indicate a problem with the battery or the starting system.

The current required to start a car can vary widely depending on the type of car and the engine it has. Small cars with small engines require between 180 and 230 amperes, while bigger cars with larger engines can require anywhere from 250 to 350 amperes.

When the car motor does not receive the required voltage and current, it will not power up. When the car battery is fully discharged, it can be dead.

What are the Reasons to Dead a Car Battery?

A car battery can be dead due to below 12 reasons.

  1. Leaving lights on
  2. Old battery
  3. Extreme temperature conditions
  4. Alternator problems
  5. Frequent short trips
  6. Electrical system malfunctions
  7. Corroded or loose battery connections
  8. Battery fluid leakage
  9. Parasitic drain beyond typical preservation mode
  10. Not driving the car for a long time
  11. Poor maintenance
  12. Fault in the charging system.

How to Determine the Dead Car Battery?

A car battery can be dead due to many drill battery problems. You can determine the dead car battery by observing the 5 behaviors below.

  1. Car is struggling to start, but it does not start
  2. Waring lights on dashboards
  3. Weak performance (light, wipers, etc)
  4. Battery leakage or swelling
  5. Battery lifetime exceeds more than 5 years.

You can start a car following 5 steps using a drill battery.

5 Steps to Jumpstart Car Battery Using a Drill Battery

You should follow the below 5 steps to jumpstart car battery using a drill battery.

1. Check the Car Battery Condition

Before you jumpstart the car battery using a drill battery, you should check the car battery’s condition. It should not be too much cool or overheated. As well as, knowing the fully discharging reason will convenience you to jumpstart and use it further.

2. Take a 12V or 18V Fully Charged Drill Battery with 5-6 AH

You should have a fully charged 12V or 18V Li-Ion drill battery with a 5-6 AH capacity. When you use a 12 V battery, it should be fully charged. If you use an 18V battery, you can use a partially charged battery. 18V fully charged drill battery will increase the charging rate.

Can I Jumpstart the Car With 20V Drill Battery?

You can use a 20V drill battery to jumpstart a car battery more quickly than the 12V and 18V batteries. Due to the higher voltage, it will charge the car battery well.

3. Connect Similar Terminals Together

You should connect battery terminals and drill battery terminals together, such as positive-positive and negative-negative using a conduction wire. The conduction wire should be enough to transmit the higher current. You can connect the terminal tightly using alligator clips.

How to Detect Drill Battery Terminals?

You can detect the drill battery terminals by checking the (B+) and (B-) near the connector. (B+) refers to the positive terminal, while (B-) refers to the negative terminal. If you can’t find these details, you should use a multimeter to detect the battery terminals accurately.

4. Wait 5 to 10 Minutes

You should allow 5 to 10 minutes to charge the car battery using the drill battery.

5. Start the Vehicle

Remove the connected wires and start the vehicle.

Hi, I am Tom Mackency. It has been 10 years that I have been working as a professional woodworker since 2013. I am really enjoying my carrier by creating many kinds of projects in my workshop. But mostly I like for home improvement projects. Home improvement and DIY projects are the most interesting things for me. More than that, the coolest things are power tools. Those are very precious and efficient than a decade ago. So I try to introduce so many things about power tools, woodworking, DIY projects, home improvement and many more interesting topics here.
