“New battery but car won’t start without jump”, this problem is more common than anyone thinks. There are several reasons why a vehicle would face the “new battery but the car won’t start without jump” problem. It is extremely normal for your car to experience the problem “new battery but the car won’t start without jump”. Having your car not starting even after buying a new battery can definitely cause panic in the minds of the owner.
If you have just installed a new battery and it is not performing properly, that might be because of a bad alternator, a faulty battery, or a problem with the starter of the car. To help you get over this problem, we have a detailed explanation that will help you pinpoint the problem. This will help you troubleshoot and get over these problems also.
How Does A Car Battery Work
A car battery looks like one of the most easily accessible and treatable parts of a car. Even though people have this misconception the battery system of a car is a complex system. An individual should know about how the electrical system and the car’s battery works.
The car battery is like the heart of a vehicle. That is why the last thing you want is to be stuck with a dead or a bad battery. The more an individual knows about how the battery system works, the better are their chances for solving the problem with the battery system.
Usually, a car battery lasts about 3 to 5 years on average. Bad driving habits and the battery being exposed to extreme temperatures can shorten the life of a car battery. Over time a car battery usually loses the ability to hold an electrical charge. This further makes the supply of power unavailable that prevents an individual from starting an engine. This is what is known as a flat battery.
The alternator in a car can be the cause of this problem. A bad alternator might be the reason why the battery might not be getting charged. A bad alternator might not be able to feed the battery with the power it needs. This will lead to a flat battery much faster than expected.
Checking And Testing The Battery
The first thing that an individual needs to do is visually inspect both the battery terminals and the connectors. If you are facing the problem “new battery but car won’t start without jump” the terminals should be clean. What an individual needs to look out for is that are the connectors clean. You also need to check if connectors are tightly connected to the terminals. If not, this might be the root of the problem.
A rusty or loose battery may cause a problem for the transfer of electricity. To get rid of this problem, you need to clean these terminals. An individual needs to turn off the car and then disconnect the battery. After that, you need to use a battery cleaner and brush the terminals with a bristled brush. Do not forget to wipe and dry properly before you reconnect the battery.
The next thing you need to do is to test the battery’s condition yourself. You’ll need a multimeter for this:
- Setting the multimeter to a 20 volts setting.
- Connect the multimeters’ red probe to the positive terminal and the black probe to the negative terminal.
- After the multimeter has taken a reading, if the voltage should be under 12.6 volts, then this confirms that the battery is flat.
- If it is more than 12.6 volts, then the battery is fine. In that case, you will want to check the fuse and ignition switch.
Testing The Alternator
Assuming the fact that the battery is flat, the next thing you’ll want to do is check your car’s alternator to verify the problem. However, this will require you to jumpstart the car as you need the engine to be running to perform the test. The only other way of testing your alternator is to remove the alternator and that is extremely complicated. Here is how to test your alternator:
- The first thing that you will need to do is to jumpstart your car with the help of another car. If you have a manual transmission, you can turn the car on by pushing the car and putting it in gear.
- Once the car is on connect the multimeters red probe to the positive terminal and the black probe to the negative terminal. Set the multimeter’s test set to the 20-volt settings.
- The multimeter should read anywhere between 14.2-14.7 volts. If the meter reads about 13 volts, then you have a weak alternator. This will not be able to charge the batteries. Especially when you turn on the accessories like the headlights and air-conditioning. Try checking the cable that runs between the alternator and the battery and check for any damage.
- If the multimeter reads far below 14.2 volts that means you’re in need of a new alternator.
The cost of getting a new alternator is around $500. For some of the cars out there a new alternator can be as cheap as $200. On the other hand, some premium cars out there can be extremely expensive.
Causes For “New Battery But Car Won’t Start Without Jump”

How To Jump A Car
If you are facing the problem, “ new battery but car won’t start without jump” you need to know how to jump a car and see if your vehicle is working properly without any issues. If your battery is dead you need to use a set of jumper cables to power your vehicle, get back on the highway and drive safely. Make sure that the battery you are using to jump the car has the same voltage battery as your car so that there are no safety issues.
Here is a list of steps you need to follow in order to jump your car:
Step 1: Get The Car Ready
The first thing you need to do is get all the equipment ready and park the car right next to the car you are going to use to jump. You might want to keep a set of jumper cables if anything happens unexpectedly. And to prevent the problem “ new battery but car won’t start without jump”.
Alongside that what you need to do is park the car you will be used to jump right next to your car. You need to put both cars in neutral and turn off the ignition. This will help prevent anyone from getting hurt during this process.
Step 2: Attach The Jumper Cables With Caution
The second step you will need to do is connect both the batteries together in order to perform the jump. For this, you need to connect the red cable to the positive terminal of both cars. Usually, the positive terminal on a battery can be easily identified. It has a ‘+’ sign made on it or “pos” written right next to the positive terminal. The positive terminal is usually bigger than the negative terminal.
The main thing a jumper cable does is share the electricity and voltage between the two cars. Without attaching the red cable to the positive terminals on both cars the positive electricity will only flow in a singular direction which will not be able to jump the car. What you need to do is connect the red wire to the positive terminals on both cars.
The black wire is used to connect the negative terminals. The negative terminals on a car can be easily identified by the “-” sign or “neg” written on the battery. Once both the positive and negative terminals of both the batteries are connected, that means that both of them are sharing their voltage and power. The car with the dead battery is now ready to be jumped.
Step 3: Attach The Black Clip Away From The Battery
Jumper cables have a black clip attached to them which helps them not to interfere with any electrical part of the car. This clip needs to be placed on a non-painted surface without any wires attached to it. An individual can use the metal stud used to hold the car hood open.
Step 4: Turn On The Car
The last step that you need to follow is to turn on the car with the dead battery and let the car run for a while. This will help the battery charge a little before you disconnect the wires. This also allows the engine to warm up. A jump start provides the necessary power to the car that is struggling with a dead battery or facing the problem “ new battery but car won’t start without jump”.
