Learn More About What Your Battery Powers

The battery is at the heart of the car. It powers all of the electrical systems - and when it fails, none of these systems will work.

THE ROLL OF THE BATTERY

Safety

Window Heating

The window heating is absolutely essential during winter and consumes 120W.

Windscreen Wiper

Keep your eyes on the road. The windscreen wipers do a good job, but they
consume between 80 and 150 watts.

Low/High Beam

Lights on – vehicle lights are essential for safety. Modern LED systems
consume as little as 50W.

Comfort

Heated Electronically

Stay warm! The heating makes use of the heat produced by the engine, but with an
energy consumption of 1000W it's still one of the major drains on the battery.

Seat Warmer

Nice and cozy! A seat warmer will typically consume 100–200 watts per seat.

Air Conditioning

When you turn the AC on, the energy mainly comes from the engine. However, on top of
this it consumes another 500W of battery power.

Accessories

Electric Sunroof

Here comes the sun. But it takes 200W of battery power to fold back the roof.

Window Lifter

The car’s window and door management system uses several electrical motors
and takes up 150W of battery power.

Cigarette Lighter

A cigarette lighter may be used to charge your smartphone and takes up another
100W on average.

THE ROLL OF THE BATTERY

Utilities

Starter

It takes 800W up to 3000W of battery power to start the engine of your car.

Radiator Fan

Uniform cooling, powerful engine performance. The radiator draws about 800W
from the electrical system.

Engine Management System

Modern cars cannot meet today’s environmental standards and requirements
without an engine management system. This uses up to 200W.

Headlamp Cleaning System

During operation, the cleaning system drains up to 100W from the battery.

FACTORS THAT AFFECT BATTERY LIFE

Excessive heat can cause sulfation and corrosion inside your battery. You usually notice the problem (trouble with cold starts and poor charge acceptance) during cold weather.

Extreme Temperatures

FACTORS THAT AFFECT BATTERY LIFE

A parked car uses up to 1% of the battery´s charge for standby functionality. In addition depending on the ambient temperature and the age of the battery, self-discharge can drain the battery within a few weeks.

Irregular Use

LIME-GREEN-BACKGROUND

FACTORS THAT AFFECT BATTERY LIFE

Driving only short distances does not give your battery enough time to recharge. In winter, high-consumption accessories such as defrosters and heated seats make matters worse.

Short Trips

THE ROLL OF THE BATTERY

As your car ages, the performance of its battery declines due to corrosion and sulfation. The sulfate crystals that form can clog the pores of your battery’s plates, preventing proper charging.
