A car battery is an essential piece of equipment, and it needs to be in good working condition for a car to run properly. One way to tell if a car battery is starting to fail is if it starts to leak. Battery leakage can be a sign that the battery is not holding a charge as well as it used to, and it can also be a sign that the battery is overcharging. If you notice any battery leakage, it’s important to take your car to a mechanic to have the problem diagnosed and repaired.

10. Heavy corrosion:

Corrosion on the terminals of your car battery is a telltale sign that it’s time for a replacement. The corrosion is caused by the build-up of lead sulfate, which forms when your battery is charging and discharging. Over time, this lead sulfate becomes increasingly difficult to remove, and eventually, it will completely cover the terminals, preventing them from making contact with the cables. If you see heavy corrosion on your battery terminals, it’s an indication that your battery is nearing the end of its life.

Position both the cars in such a way so that you can connect both batteries properly with jumper cables without any possibility of disconnection.

3. Connect The Jumper Cables:

Connect the jumper cables to battery

Before connecting the jumper cables, make sure the ignition of both cars is on. Then clamp one end of the jumper cable to the positive terminal of the dead battery. Connect the other end of this positive jumper cable to the positive terminal of the good battery. Follow the same process when you connect the negative clamps of the dead battery and the good battery.

4. Jump Start The Battery:

Start the car with a good battery first. Then try starting the car with a dead or weak battery. If the car with a dead battery starts, keep it in this state for a few minutes to let the battery get recharged.

5. Detach The Jumper Cables:

Detach the jumper cables in reverse order.

6. Keep The Engine Running:

If your car won’t start, it could be due to a weak battery. But how can you tell if the battery is the problem? One way is to use a multimeter to test the battery. This device can measure electrical current, voltage and resistance, so it’s ideal for testing car batteries. Here’s a complete stop-by-step guide on how to do it:

Step 1: Make sure that the multimeter is turned off and the probes are not touching anything. Then, touch one of the probes to the positive terminal of the battery and the other probe to the negative terminal. If the reading on the multimeter is 12 volts or higher, then the battery is fine. However, if it’s below 12 volts, then the battery may need to be replaced.

Step 2: Check the voltage readings while the engine is running. First, turn on the engine and let it idle for a few minutes. Then, touch one probe to the positive terminal of the battery and the other probe to any metal part of the car body. The reading should be between 13 and 14 volts; if it’s lower than this, then there may be an alternator problem.

Step 3: Check the resistance readings across each cell in the battery.


If you spot any of these signs indicating a bad car battery, it’s important not to delay. Reach out to a nearby mechanic promptly to get your battery inspected. This can save you the trouble of dealing with a dead battery while driving. Getting a new battery is a smart move to resolve this issue effectively. Additionally, regular car maintenance plays an important role in extending the lifespan of your battery.


1. How to tell if a car battery is bad?
If your car needs a jumpstart more often than usual, this may be an indication that the battery is no longer holding a charge as well as it used to. Another sign of a bad battery is dimmed or flickering headlights.

2. Can a bad battery cause electric power steering problems?
If your car has electric power steering, then a bad battery can definitely cause problems. The power steering system relies on a small electric motor to assist you in turning the wheel.
