The Car Keeps Dying Battery and Alternator are Good: Why?

Nothing is more annoying than trying to start your automobile after going outside. Numerous factors might cause car batteries to fail. However, if your “car keeps dying battery and alternator are good,” it’s very reasonable to assume that there’s a larger issue that has to be resolved while you find yourself stranded.

The car keeps dying battery and alternator are good: What for? You may be having problems with recharging or a parasitic leak if the battery pack is dying, yet the alternator is working correctly.


Similar to how the physical heart pumps blood throughout the body, the car’s engine is what propels it forward. Among those essential elements for the motor to operate properly is the cell. Similar to a raincoat during a cyclone is a drained cell. The good news is that with a little assistance, determining what is destroying your battery is easy.

Indications of a Faulty Battery

Look out for these typical battery tender signs.

How Bright are Indeed the Panel Lights?

First, look there at the battery indicator on the panel. Even if the car isn’t moving, the battery ought to be charging. The cell is probably having a problem if your panel lights appear dim.

Inspect for Rust in the Batteries

Whether it didn’t bother you, thoroughly remove any rust on the cell with a cloth before having somebody jump-start it. The problem arises if you are unable to get the computer to restart.

The Automobile Battery May be Out of Date

Because of internal corrosion, batteries lose their capacity to hold a charge as they grow older. The cell ultimately reaches a point where it is unable to store enough energy longer to begin the automobile, regardless of the amount of energy the alternator supplies it with.

The Radio is Not Working

There is a significant chance your cell isn’t fully charged if you see the radio screen or the headlamps fluctuating or fading.

You Have a Bloated Battery

You must be able to recognize a swollen battery.

Indicators of a Damaged Alternator

It’s essential to watch out for particular poor alternator signs.

The Interior Lighting is Dim

Take notice of how bright the inside lights are when the car is operating. Your alternator is probably at blame if the display progressively darkens.

Headlights that are too Dim or Dazzling

Does anyone observe a brightening or fading of the lighting when you drive or halt? The alternator’s inability to maintain the cell sufficiently recharged is a common cause.

Sounds of a Growl

Even before the issue began, did you detect anything growling? That can occasionally happen even before the alternator breaks out.

It Smells Like a Heating Element or Burnt Rubber

Burnt tires or sizzling wires odour might be a warning that your alternator was overheated. If so, it has to be replaced.

The Car Keeps Dying Battery and Alternator Are Good: Why?

Users’ irresponsibility, problems with the power system, as well as the cell themselves are indeed the three primary factors at fault. Sure of the issues listed below are sufficient to kill a cell by itself, whereas others are typically combined with a cell that is currently poor or near death.

Leaving the Dome and Headlights Active

A cell would discharge overnight if lights are used, or even an extremely faint dome light. Even though sure headlights are intended to stay on for a short period of time, a broken system might keep them on all the time.

Low or Damaged Battery

Battery health and strength can affect how effectively it holds a charge. An extremely weak cell may be destroyed by even little draws.

Damaged or Faulty Cell Connectors

Your recharging mechanism may be unable to top up the cell while you are traveling due to corroded cell connectors. Corrosions prevent the cables from connecting to the electrical connections correctly, which makes it harder to charge the battery and prevents the wires from receiving electrical energy from it.

An issue might also arise from loose battery connectors. An alternator might malfunction due to strained or slack belts as well as worn tensioners.

Various Electrical Grid Parasitic Discharges

When a vehicle’s battery discharges even while the motor is off, particularly so over the course of an overnight period while it is not being used, this is known as parasitic battery drain. Although they might be challenging to locate, parasitic drains have the power to eradicate batteries.

Climatic Extremes, Either Warm or Cold

A battery that is brand-new or in excellent condition won’t be destroyed by high heat or cold. However, a cell that is poor or old could fail under such circumstances. Extreme temperatures can aggravate further underlying problems.

Climatic Extremes, Either Warm or Cold

Faulty Charging Systems

A problem with the charging mechanism could be to blame if a battery seems to expire while you’re traveling. Whether or if your car’s alternator is in excellent working order, a defective cell that intermittently charges or continuously drains by itself will continue to lose power.

The solution is to take out the battery, completely charge it using a rechargeable battery, or swap it out.

The car keeps dying battery and alternator are good: How do you solve it?

Evaluate the Batteries

Checking the voltage using a multimeter would be an option, although it only provides limited information. This is so that you understand that the cold cranking amps are what truly start your automobile. You require a specialized tool in order to verify cold starting amps.

Look Over the Alternator

Although you believe everything to be in order, did you do the proper checks? To determine whether the alternator is operating correctly, you must examine the voltage output. Its output should range from 13.5 to 15 volts if everything is in order.

Keep an Eye Out for Parasitic Draws

Whenever the alternator is not recharging the cell, anything is destroying it. If the alternator is operating and the cell is retaining a charge, this indicates that something is dying in the battery. That shows you have drawn.

Verify the Proper Wiring for the Alternator

Although it’s uncommon, it does occasionally happen. The best course of action would be to confirm that the wire connecting the alternator to the cell is sound and linked correctly. Corrosion on these cables might increase resistance. The alternator’s output voltage is useless if the cell never receives it.
