Removing the starter battery or motorcycle battery
If you want to remove a start-stop battery: inform the vehicle system before removal.
First disconnect the negative cable (usually black), also called ground or earth, from the negative terminal of the battery.
Then remove the positive cable (usually red) from the positive terminal of the battery.
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.

Check the state of charge …
What does maintenance-free mean?
In maintenance-free batteries, the electrolyte is in liquid form. They are usually closed at the factory, often with a double or labyrinth lid in which any gases produced condense and remain in the battery. In normal operation, maintenance-free ones do …
Chargers for traction batteries
As with supply batteries, traction batteries are used in cyclic applications, i.e. the batteries are used until they are quite empty and are charged during idle times. Here, the charger is part of an effective drive application. The efficiency of the …
Ideally, batteries should be kept dry. Even slight moisture can promote leakage currents.
If you've noticed condensation on your battery frequently in the past, such as with temperature fluctuations, or water can get to your battery, it's worth considering …
The order of disconnection and connection

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.
