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!
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.
