The order of disconnection and connection
The negative terminal is connected to the body, hence the name grounding. If you accidentally touch the positive terminal and the body at the same time when the negative terminal is connected, e.g. with a metallic tool, a short circuit could occur that …
Why are the labels coming off my battery?
Detached labels indicate wear due to excessive temperatures.
Tip: Always give your battery time to cool down before charging or use a charger that charges temperature compensated.
Tip: If you operate your vehicle or device in a very hot environment, choose …
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 …
Always choose the right battery for the application
When choosing a battery, it basically depends on what it is to be used for.
The most important distinction is between starter batteries, including motorcycle batteries, and cyclic batteries such as traction or supply batteries.
Starter batteries, including …
These block batteries ensure the uninterruptible power supply (UPS) of POS systems or smaller computer systems as well as security systems such as locking systems or security lighting when the power grid fails. UPS systems also protect the connected loads …
What is wear and what can you do about it?
With a worn battery, the active material has degraded due to excessive load. Modern vehicles with many consumers constantly place higher demands on the battery. The capacity of the installed batteries is often not designed for this.
Prevention
The choice …
What types of supply batteries are there?
In order to withstand the stress of cyclic operation for a long time without an excessive drop in performance, the active material in supply batteries is particularly well protected.
Depending on the technology used, this is done in different ways:
In …
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 …
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. …
Identifying and filling the liquid level
Markings on the outside of the white or transparent housing of a wet battery indicate the minimum (MIN) and maximum (MAX) fill levels.
During commissioning or initial filling, the battery must be filled with battery acid up to the upper mark (MAX).
During …
