Charger Knowledge

Transformer charger versus high-frequency charger
Transformer chargers with a downstream rectifier are relatively inexpensive, but they are large, heavy and less efficient than high-frequency chargers. They allow 1- to 3-step charging methods based on the W-characteristic (W, Wa, WaPuls, W0Wa, WU, WUWa …
Chargers in a workshop
Especially for workshops, there is another charger that supplies the vehicle with power during diagnoses and software updates on the vehicle electronics. During this phase, the vehicle management system requires a particularly large amount of power and …
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, …
Safety instructions for handling acid
Battery acid consists partly of sulphuric acid, which is highly corrosive. It attacks your skin, textiles and even metal. Put on protective clothing! So always wear gloves, safety glasses and possibly an acid-proof apron when handling batteries. Choose …
What does that even mean? Charging curve?
Current and voltage during charging can be measured and displayed as a curve over the course of the charging time. Depending on which processes, controls by switch-off (a) or switch-over points (0) are possible with a charger, one speaks of the provided charging characteristics.
Why is the charging voltage of the charger important?
In principle, when charging, the electrons within the battery move from one electrode to the other, in the opposite direction to when they draw current, i.e. discharge. If a discharged battery is provided with too high a voltage from the current or voltage …
Charging correctly step by step
Tip: For full performance: Charge before first installation! 1. preparation Check that your charger matches the battery. Does the charger support the correct charging voltage? Does the charging current provided match the battery? What charging curve …
Which charger for which battery type?
The most important distinction is that sealed batteries and especially lithium batteries can react extremely to the heat and overpressure during overcharging. A reliable cut-off is particularly important here. Modern fully automatic electronic chargers …
Chargers for rescue and safety vehicles
Emergency and rescue vehicles and other safety-related types of vehicles often sit around for months, but when it comes down to it, they need to be ready at a moment's notice to put out fires, rescue injured people or clear roads. Chargers like the Fronius …
Cleanliness pays off
To ensure proper battery function, it makes sense to keep the battery surface clean and dry. Greasy or silicone-containing dirt on the lid can hinder the flow of current. Moisture on the battery can cause a short circuit in the worst case.
