How long will a battery last with a bad alternator? The answer to this question depends on how often the battery is charged and how much power it’s pulling. If the alternator is not working, you should charge your battery as often as possible.
A car depends on the battery to start and run the ignition system and then get the engine running. While the alternator supplies continuous electrical charge to the battery to keep it charged and healthy.
The battery depends on the alternator to stay alive and thereby keeping other electrical components functional. The headlights, electric steering, power windows, windshield wipers, heated seats, dashboard instruments, and radio all greatly depend on the alternator.

How long Can a new car battery last with a bad alternator? New car batteries are a great convenience for drivers and they last for years. However, if your alternator goes bad, you will need to replace it soon.
The average lifespan of a new car battery is around 500600 charge cycles. The lifespan of the battery can be extended to 1,000 charge cycles by replacing the old battery with one that has more than 80% capacity left.
As I have mentioned before, how long a battery lasts with a bad alternator is not certain as it depends on many various factors. Factors that determine your car’s battery life range from weather to engine type and amount of electronic components.
So therefore bear in mind your battery will not last with a bad alternator. Your car’s battery needs to be charged by the alternator. If it’s bad then the opposite will happen.
If you don’t want to purchase a new car battery, there are other options that you can use to extend the life of your old one. One option is to use a trickle charger on your battery when it’s not in use and charge it every day or so.
Risks of Driving with a Bad Alternator
Driving with a bad alternator can be dangerous. It can cause your car to lose power and stop working altogether. It can also cause your battery to drain quickly and even catch fire.
The following are the risks of driving with a bad alternator:
- Loss of power: If your car loses power, you might not be able to make it to the nearest gas station. You might also have trouble getting back on the road if you’re in an area without a lot of traffic or people around you.
- Battery drain: A bad alternator will make your battery drain faster than usual, which could leave you stranded if it drains completely and leaves you unable to drive away from where you’re at.
- Fire hazard: If your battery catches fire.

Can You Jumpstart a Car with a Bad Alternator
The most common way to jumpstart a car with a bad alternator is by using jumper cables. This process will require you to turn the ignition on and off in order to create a spark.
However, this method is not always possible because the car might be too far away or it might be out of reach. In these cases, you can use an electric generator instead.
How to Tell if Alternator is Draining Battery
The Alternator is a very important part of the vehicle, and if it is not working properly, it can cause some serious problems. There are certain telltale signs that show you if your alternator is draining your battery.
The first thing to check for is the amperage drawn from the battery. If this number is high, then there’s a good chance that your alternator isn’t working properly.
If you have a low amperage draw from the battery, then there’s still a chance that your alternator could be draining your battery. The only way to know for sure would be to take it to an auto mechanic or contact an independent mechanic who can do an inspection on the vehicle and find out what’s wrong with it.
How Long Will Boat Battery Last Without Alternator
With the increasing demand for longer battery life, the need for an alternative power source is becoming a necessity. Boat batteries are not as powerful as car batteries and they also have a limited range of use.
They can only be used for short periods of time without an alternator. An alternator is a device that converts mechanical energy into electrical energy by means of electromagnetic induction.
It’s typically found on cars, trucks, boats, and ships to convert the engine’s kinetic energy into electrical energy to power onboard electrical loads such as lights, radios, and other accessories.
How Long Does a Charged Car Battery Last
The battery life of a car is important because it is a crucial part of the vehicle. When the battery dies, you will not be able to start your car. This can be a frustrating experience, especially when you are in a hurry and need to get somewhere on time.
The lifespan of your car’s battery depends on how often you use it and how much power it has to hold. If you are driving around town or just going for short trips, then the lifespan will not be as long as if you were driving on long-distance trips or charging your battery every night at home.
The average lifespan of most car batteries is about five years. But this varies depending on which type of battery you have and how well it was maintained before its death.
Bad Alternator vs Bad Battery What to Know
Well left to me I would prefer none of either a bad alternator or bad battery as this can cause disappointments and unpleasant experiences. The alternator and the battery serve different purposes but they both depend on each other to stay in good shape and keep the car going.
A good alternator serves its purpose by continually sending charges to the car’s battery so as to keep it alive and replenishing the electrical charges that are being used by the electrical components. The battery on the other hand does the work of helping the ignition system turn thereby making the car’s engine start and as well regulating the current being sent to other various electrical components.
Here are signs and symptoms that your battery is bad and what to do to manage the bad battery condition.
- Dim headlights
Whenever your car’s battery starts going bad, the headlight’s brightness tends to start shining dim. This happens as a result of not receiving enough current flow from the alternator to keep it charged up or the battery is totally dead.
The headlights of the cars consume the most amount of battery current after the car ignition which consumes the most and drains the battery charge. The headlights consume 10 times the amount of current all the electronic gadgets consume altogether.
- Clicking sound when you turn the key
This happens when the car is about to ignite when the amount of current from the battery to the Kickstarter tends to delay and start making clicking sounds when the ignition is put on. The clicking sound that happens whenever the car is about to start is another good indicator of a bad battery.
- Needing to Press on The Gas Pedal to Start
Whenever you try starting your car and it won’t start until you press down the gas or flout the carburetor before the car starts, it is a sign of a dead or bad battery.
Other signs and symptoms of a dead or bad battery are the following
- Slow crank
- Backfiring
- Needing to press on the gas pedal to start
- Egg smell
- Corroded battery terminals
- An old battery
What causes a car battery to die quickly?
The battery is charged and kept charged from the current flowing from the alternator when the car is being driven. So if your alternator is bad then expect your battery too to die very soon because it’s not being charged.
You should also know that if your car sits in the driveway for long periods of time you run the risk of killing your battery. Other factors too like how old your battery is and climate conditions would greatly determine how fast your car’s battery would last or die.
Similarly, making a lot of short trips that don’t allow the battery to recharge can strain the system. And last but not least, don’t forget to turn your lights off we all know how that ends!
Can a Car Run With a Bad Alternator?
The simple and direct answer to this question is whether a car runs with a bad alternator, but there are conditions to it. A car can be jump-started even if the alternator is bad or not working at all.
Your car will start when jump started if your alternator is bad but the battery is either new or fully charged. But you have to bear in mind that the alternator keeps the battery charged and alive so if it is not working then your battery stands the chance of dying in no time.
I guess you wouldn’t want a situation where you will spend a lot of money on getting new batteries every time. My adverse reaction is that if you know that your alternator is bad or not working well then endeavor to get it replaced or fixed.
Conclusion
The battery is the most important part of a car. It stores energy that powers your vehicle and allows you to travel. In this article, we discussed how long a battery can last with a bad alternator.
