5 Reasons Your Car Battery Keeps Failing and What to Do

Car Battery
A car battery that will not start can be a driver's worst nightmare, especially if you are stuck in traffic or on a deserted road. Sometimes, a failing battery will give off signs of trouble, but much of the time, battery problems can catch you unawares. If you are stranded on the roadside with a dead battery, consider calling a towing company to help you jumpstart your car.

Here are a few reasons why your battery keeps stalling.

1. Age

If you are driving around with an old battery, chances are you will find yourself on the roadside needing to jumpstart the battery.

An old battery will not hold a full charge for long. Car batteries have an average life span of 4–6 years so you should be keen to replace yours at around this time.  

An old car battery will make cranking noises when you turn on the car. You may also notice that none of the lights turns on when you start the car.

If your car will not start, get in touch with a reputable local towing company to help you jumpstart the battery or to tow the car to the nearest repair shop.

Bear in mind that an old battery may only be able to jumpstart once or twice and will completely stall at some point. Replace your old battery to avoid such a situation.

2. Drain

Drain refers to the energy your battery continues to lose even after parking your car. Some drain is inevitable because your car battery continues to power background processes such as the security alarm, radio, and clock when you are not driving.

However, several factors can lead to excessive drain and minimize your battery's service life. For example, aftermarket car alarms tend to use up excess energy, draining a fully charged battery within days.

That thumping stereo you installed recently could also be draining your battery dry. Draining is especially likely if the amplifier is set improperly and will not go into standby mode.

To improve the longevity of your battery, consider minimizing the components in your vehicle that use up too much energy. Most of the time, these are cosmetic components that do not directly affect the performance of your vehicle.

3. Faulty Electricals

Faults in the car's charging system can result in the battery not topping up correctly. The alternator is responsible for charging your car's battery.

Problems such as wear and tear on the tensioners and sagging belts can affect the performance of the alternator. As a result, your battery may fail to charge fully, increasing the risk of sudden battery failure.

Regular maintenance can help to detect and prevent problems with the alternator before the issue gets out of control.

4. Corrosion

Over time, battery connectors, cables, and terminals may succumb to corrosion. Visible corrosion appears as large green, white, or blue patches of residue on the battery.

This corrosive residue will prevent current from flowing from the battery to the car's starter motor. Additionally, corrosion on the cable connectors and terminals will also interfere with the alternator's ability to charge the battery when you are driving.

5. Faulty Headlights

Leaving your headlights on for prolonged periods will drain your battery. Some headlights may stay on for a short while before turning off. However, electrical problems can keep the headlights on, hogging valuable current needed to run your vehicle. 

Also turning on the interior lights in the car can suck your battery dry. Use interior lights only when necessary.

A dead battery can be inconveniencing, but with regular maintenance, you can avoid many of these problems.
