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 …
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. …
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 …
Drive batteries with grid plates
The classic lead-acid battery in the closed, low-maintenance design is suitable for the light operation of golf caddies, wheelchairs, cleaning machines, mobile lifting platforms or light industrial trucks. With the best price-performance ratio, good high-current …
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 …
Round cell drive batteries
The "wound" grid of the round cell battery combines the advantages of a supply battery with good starting characteristics in a relatively small space. The battery has good recharge behaviour after deep discharge and good cyclic behaviour (approx. …
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.
Drive batteries with armoured plates
Wet deep-cycle batteries in armoured plate or tubular plate technology are designed for the heaviest loads. Several tubes, in which the active mass is quasi "armoured", are joined together to form plates. This design makes them extremely resilient …
What is short circuit and how do I prevent it?
Short-circuiting occurs when the two terminals or plates of a battery are accidentally connected together. This can happen if the separator between the plates is damaged by vibration, for example, or if excessive battery sludge builds up, closing the …
Always choose a battery that matches the load
Depending on the type of battery, it is designed for certain loads:
Starter batteries must deliver as much current as possible during the starting process. The cold start current, measured in CCA, is informative here and shows how much starting power …
