Determining car battery size made easy!

Abmessungen Batterie Teaser

A battery should have a long service life, as much power as possible or plenty of capacity for many consumers. But at the end of the day, the battery must above all fit into the vehicle. Length, width, height - if you know what's important, you'll enjoy a battery that fits right from the start.

Car battery replacement: check dimensions & installation space

The installation space is crucial for starter batteries, so open the cover and take a look at the conditions. It is best to measure the old battery, as the new one should fit in again. You can find out what you need to look out for in our article.

How exactly do you measure?

Regardless of the shape of the battery - protruding terminals, recessed terminals, base plate or round cell - the absolute mass of the battery always applies. This means

The absolute length including the cover overhang, the absolute width including the base strip and the absolute height, i.e. up to the height of the poles, or up to the highest point of the battery if the poles are recessed.
The Graphic shows how to measure the length, width and height of a battery correctly.

Note the circuit

The circuit plays a role in ensuring that the poles are exactly where they should be connected.

Simply turn the battery so that the side closest to the poles is facing your own body. Of course, keep it upright, although a brief tilt of up to 45° should not be a problem with any battery. The decisive factor now is which side the positive terminal is on, right or left or sometimes at the front, e.g. with a US front terminal battery.

Individual planning instead of predefined installation space

If you don't want to replace a battery but want to choose one for the first time, for example for a special vehicle or a custom bike, you start from the available space. For many applications, there are batteries that are particularly compact, for example pure lead batteries, which still provide a lot of starting power with smaller dimensions or...

... round cells with wound grids, which provide a lot of capacity in a small space in terms of supply and drive.

If it has to be particularly light and small, the lithium battery is the best choice with very high starting power and very high, fully usable capacity in a very small space.

When choosing a battery, dimensions are usually the last thing you think about. But what good is the best battery if it doesn't fit in the vehicle?
