Checking the liquid level against sulphation
In a battery or accumulator, the chemical reaction between the active material of the grids and the acid generates current (electrons emitted) to supply the loads or stores current (electrons) provided by the charger or alternator.
If the acid only partially …
Also important for starter batteries: the consumers
Even before the engine is started, the starter battery has to do a lot and supply standard equipment such as the lighting system. This draws current from the battery, which is no longer available for starting.
Nowadays, there are also a number of consumers …
Dimensions before starting power
First of all, a battery must fit in your vehicle or machine. Check the dimensions of your old battery or the available space in the battery compartment of your vehicle.
The placement of the terminals, i.e. where exactly the positive and negative terminals …
What is a starter battery?
A battery that is charged by the alternator and starts the vehicle. For this purpose, the starter motor requires a lot of current for a short time. In addition to the cold start capacity (CCA), which indicates how much current the battery can ideally …
Charge lithium battery before installation
A battery that is not fully charged when installed will not reach its full performance in the future and will have a significantly shortened service life.
Lithium batteries can also lose charge during storage. We recommend that you also fully charge them …
In a nutshell, the battery generates electricity, which it delivers to the consumers. It is charged and is ready again.
So far, so good. Meanwhile, a bit of chemistry happens inside the battery.
Current flow
In principle, current flows between a positive …
Checking the battery step by step
There are many reasons for weakening or failing batteries. An important step in tracking them down is to measure the voltage with a battery tester.
Here's how:
1. preparation
Disconnect the battery from the vehicle, if possible remove it. Tips on how …
Whether short or long: charging takes place while driving
How much time does your battery normally have to charge? If your journeys are never shorter than 100 km, this is different from if you regularly only drive distances of 1 - 2 km. The alternator charges the battery with a steady, low current. It takes …
How does a melted pole occur?
A melted pole is caused by a short circuit when the battery polarity is reversed during bridging or when the poles are connected by a tool or other object.
Tip: Take care when handling batteries.
Learn more about short circuit and how to avoid it.
Why should you charge wet batteries open?
Gases are produced during charging. As they rise, they mix the battery acid.
It is better for the battery if it is open during this process.
Important: This only applies to initial charging and to all batteries that can be opened. Never open a battery by force!
