How To Kill A Car Battery In 9 Lessons Or What Not To Do | Use

ONE battery failure can be boring, but most of the time it can be avoided.

Modern vehicles have a power-intensive technology. If we add a change in driving habits after the lockdowns related to Covid19, a dead or dead battery is more common than three years ago.

CTEK, specialist in charging solutions for vehicles, details the 9 worst practices that can drain and/or affect the performance of a vehicle’s battery.

1. Take short trips

If you regularly make short trips, especially in urban areas, the battery will discharge faster.

It requires 150 to 350 A battery current just to start the car. On short daily trips, the generator has neither the time nor the capacity to replace this energy consumption. On several short trips, the battery is quickly flat.

2. Allow the vehicle to experience extreme temperatures

The outside temperature affects the condition of the vehicle’s battery. A battery in a temperate zone lasts 47 months compared to 30 months in a very hot zone.

During heat waves, the most frequent problems are mainly battery and engine cooling problems. The battery is much more stressed (air conditioning and ventilation are running at full speed and the electrolyte tends to dry out).

Similarly, a battery can lose up to 35% of its performance when the temperature reaches freezing, and up to 50% if the temperature drops below minus 10 degrees in winter.

3. Leave the key near the vehicle

Leaving the car key overnight or even on a hook near the vehicle can continue to communicate with the car, draining the battery unnecessarily.

4. Allow the battery to discharge without responding

A standard lead-acid battery naturally discharges 0.1 V per month, even if it sits on a shelf. It may not seem like much, but if you consider that a fully charged battery is 12.72V and a chemically discharged battery that the car has difficulty starting with is 11.8V, in just eight months of non-use, the the battery seems flat.

This does not take into account other discharges which can also affect the life of the battery.

In addition, the phenomenon of sulphation appears from 12.2 volts: it is destructive to the battery’s lead elements.

5. Promote continuous energy consumption, including when parking

When the car is stationary, the battery powers things like the clock, radio, electric parking brake and alarm system, even though these things don’t have much impact on the battery.

On modern vehicles, engine cooling fans and other systems continue to run after the ignition is turned off to quickly cool the engine and prevent damage.

The vehicle can manage its own network and communicate with the manufacturer’s servers via the Telematics Control Unit (TCU).

Automatic updates sent, the ability to remotely turn on lights, heat, etc., from one’s phone via an app can also pass through this network.

6. Play with opening the doors and trunk or leave the doors open with the engine off

Every time the driver opens the doors or trunk to get something out, the car comes to life and interior lights like doors drain the battery.

Unlocking the vehicle, opening the trunk and re-locking the vehicle can consume approximately 50 A from the battery. It may seem like a trivial matter, but doing this regularly can have an impact on battery voltage. The impact is none the less negligible, as all the vehicle’s systems are activated during the short time the car is open.

7. Promote parasitic discharge

Stray battery discharge constantly drains the battery. It could be a headlight/light switch, alternator or other electrical problem. To avoid this, the driver can ensure that all lights are switched off and that the boot, glove compartment and doors are fully closed and locked before leaving the car.

8. Letting generator failures linger

The car depends on the battery when the driver starts the engine.

When the vehicle is running, the battery depends on the alternator to keep it charged.

If the alternator isn’t working properly, it won’t charge the battery properly, which can make starting the car difficult.

9. Don’t worry about sulfation

A chemical reaction called sulphation occurs if the battery drops below 12.2V.

Lead sulfate crystals then begin to accumulate on the battery plates, degrading the battery, reducing its capacity and starting potential.

The vehicle starts easily if the battery is at 12.2V, but at 12.2V the battery is already dying.

“Nothing lasts forever, including your car battery. In many cases it depends on where you live, how you drive and how you maintain your battery. More than 87% of batteries returned under warranty are not defective but suffer from sulphation. Charging your car battery at least once a month extends its life up to three times. Buying a reliable battery charger and setting up a regular battery maintenance routine therefore makes perfect sense, all year round. And since battery failure can damage or compromise a vehicle’s electronic components, a charger is definitely worth the investment.” explains Abel Santirso, regional manager CTEK.
