What do discoloured plugs mean?
A brown-reddish discoloration of the plugs indicates an overcharging of the battery and a fault in the charging system.
Tip: Your workshop can check whether your charge controller is working properly.
Tip: Check the function and characteristics of your …
Recognising and classifying battery damage
When the battery fails, it's annoying. Sometimes it's because of a faulty battery, sometimes it's because of the way you handle it. And only cause research and precaution helps permanently.
What is wrong with the battery can often be seen from the outside. …
Before the winter or summer break, it is best to remove the battery or at least disconnect it and store it in a cool (ideally at 10 to 15 °C) and dry place. Charge every 4 to 6 weeks for 24 to 48 hours with a suitable charger.
Check the state of charge …
AGM or GEL drive batteries
Drive batteries in AGM or GEL technology are sealed, absolutely maintenance-free, leak-proof batteries in a closed design with a fixed electrolyte (in fleece or gel). Both are suitable for medium to heavy cyclic use, for example in cleaning machines, …
Determine excessive self-discharge
If the battery charge drops significantly, possibly overnight, this may be due to leakage current. Silent, unwanted loads can be detected with an ammeter. Oils or liquids deposited on the surface of the battery can also cause considerable self-discharge. …
Why does this battery have such a good current draw?
Due to the AGM technology, this battery absorbs the current particularly well, i.e. it recharges faster than a conventional wet battery and you can charge it with a higher charging current or a more powerful charger, like the ?
This characteristic comes …
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!
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.
What do deposits on the battery plugs mean?
Black deposits on the plugs indicate a battery that has worn out prematurely due to continuous excessive load.
Tip: Always ensure a good balance between current drain and charging.
Information on capacity calculations and charging behaviour can be found …
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 …
