An exhausted new battery can be quickly revived by jump-starting. By attaching the positive battery terminal to the red cable of the other car’s battery and the black wire to the negative terminal of different car’s battery and vice versa, you can begin the jump starting procedure.

Start the engine of the vehicle with a good battery, let it run for minutes then removed the cables, give it another two minutes before running the car. By this time, you can already hit the road.

What is the Easiest Way to Recharge a Dead Battery?

First and foremost, a car owner must know how dead his battery is before charging it. Most good batteries will have a reading of 12.4 to 12.7 Volts in the voltmeter. The voltmeter will tell you if there are existing issues in your cell.

If the voltmeter reads somewhere below 12.4 V, then you are about to experience hard starting on your engine. Any reading lower than that would already entail you to jump start your vehicle.

Here’s how you charge you battery according to how dead it is:

A Reading of 12Volts and Above

If your battery reading goes beyond 12Volts, you can recharge it by using the car’s alternator. It only means that you need to drive along to be able to charge the battery by using the alternator. A thirty minutes drive is enough to get the battery fully charged.

A Reading of 12Volts and Below

If the reading in your voltmeter reads something below 12Volts, then you are compelled to use a charger. Your car battery is already discharged when it drops below 12Volts on the meter reading. The alternator can no longer charge a dead battery, and you need a charger to do the job. Forcing the alternator to charge the battery will only damage it.

When the battery is completely dead, your next best choice is to jump start or charge it using a battery charger.

Is a Car Ultimately Charged by Just Jump-Starting it and Driving Around?

Yes, the car can completely charge it can be fully charged by driving it around for at least 30 minutes. The alternator does its job of recharging the battery, considering that it is not entirely dead.

The battery is already up for a replacement, and no amount of jump starting can revive the battery. Most batteries would typically last from 4 to 5 years.

What is the Effect of Running with a Drained Battery and Jump Starting it Every Time?

If you have already started jump starting your battery and only runs fine until you turn off the engine, then it could be a bad battery. However, if the alternator is wrong, then there would be a red light flashing on your dashboard. So, when the battery drains too much, there will be no power left for the spark plugs to work and your vehicle will be stalled.

Having a bad battery would only mean that the alternator is going to run capacity of 100% to charge the battery. When you are on a highway, you are not going to be a problem because the alternator will be a little cool.

If you keep jump starting your battery, the shorter the battery life is.
Eventually, your battery will deplete soon. Replace the battery as soon as you get signs that it needs a new one.

Why Does My Car Dies When I Jump Start?

If your car still dies after jump starting, it only means that your battery is already up for a replacement.

Batteries are subjected to wear and tear. When it already does, sediments starts to build-up at the bottom of your battery case. Sometimes when the build-up thickens, it makes contact with the battery difficult. Thus, it will fail to start.

However, if after jump starting and the battery dies right after removing the jumper cables, then probably your battery is really up for a replacement.

After Jump Starting My Car, Will it Run / Start on its Own?

Well, it depends on the reason why your battery is weak. If the reason for the weak battery is you forgot your headlights on and other accessories as well, then the car will start on its own later. The battery will keep the vehicle starting again and again. The alternator can recharge the battery, and it is back to its normal usage yet.

However, when the battery is already considered old, then you would have to jump start the battery every time because it already fails to hold a charge.
You need to replace the battery then.

Can a battery be too dead to jump start is a question that most car owners should know. You can always jump start your battery. However, when a battery is already up for a replacement, you will resort to always jumps tarting your battery.
