Batteries without vent hose
Only conventional, wet batteries need a vent hose, because they gas strongly during operation. The resulting steam can escape through the openings in the plugs. To prevent the vapour from damaging the vehicle, conventional batteries are vented to 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 …
What does low maintenance mean?
Low-maintenance batteries can be recognised by the removable sealing plugs on the top, the vent hose and the white or transparent housing. In these batteries, the electrolyte is in liquid form, i.e. it is not bound as GEL or in fleece. They are not sealed …
What is a camper battery?
A supply battery used in motorhomes or campers, colloquially known as a camper battery. Typically, it is charged with stationary charging current at the RV parking lot or via a solar system, because the alternator is not sufficient to provide the necessary …
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 …
Utility batteries, which can be used as temporary storage for photovoltaic (PV) or small wind systems, are highly cycle resistant, meaning they can withstand different charging cycles well. In the renewable energy sector, charging cannot be done with …
What does absolutely maintenance-free mean?
Absolutely maintenance-free batteries are valve-regulated lead-acid batteries or VRLA batteries (VRLA = Valve Regulated Lead-Acid) that are sealed at the factory. Here, significantly less gas is produced than in wet batteries. The gas produced remains …
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 …
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 …
Charging during long idle periods
If the vehicle is stationary for long periods and you make a lot of short journeys, it is advisable to charge the battery regularly with a charger, even if the battery has a low self-discharge rate or high cold-start performance. The exact intervals depend …
