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 …
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 …
Filling a dry pre-charged battery
Dry pre-charged batteries must be filled with battery acid and charged before installation.
Checking the battery step by step
There are many reasons for weakening or failing batteries. An important step in tracking them down is to measure the voltage with a battery tester.
Here's how:
1. preparation
Disconnect the battery from the vehicle, if possible remove it. Tips on how …
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 …
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, …
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 …
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!
Chargers for supply batteries
In order to supply the connected consumers permanently, supply batteries usually have a larger capacity than starter batteries, which are intended to deliver a lot of power, especially in the short term. Chargers designed for starter batteries reach their …
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 …
