AGM technology


If you want a high cold start performance, the AGM is the starter battery of choice. Why the structure of the AGM also has an effect on the service life of a battery and for which applications the AGM is not suitable, you can find out here. 


Sealed and absolutely maintenance-free

AGM (=Absorbent Glass Mat) batteries contain separators made of glass fiber fleece that absorb the entire electrolyte. As a VRLA (valve-regulated lead-acid) battery, it is sealed and absolutely maintenance-free. Gas generated during normal operation is recombined to form acid and bound back into the glass fiber fleece.

Plenty of starting power, fast charging

Due to the glass fiber fleece, the reaction takes place on the complete contact surface of the plates. This leads to a much faster electron exchange and thus more cold start performance. However, it also ensures that the charging process is much faster and more effective than with liquid electrolyte. This better charging behavior protects the battery better against premature aging and makes it more resistant to cycling. This helps in vehicles with start-stop technology and for many short trips, as well as when charging with solar technology.

More resistant to vibration, but only slightly more leak-proof

Because the plate packs are compressed and the separators fit tightly, AGM is more resistant to vibration. For agricultural machinery, for example, there are particularly vibration-resistant batteries with AGM technology.

The AGM is always the suitable starter or motorcycle battery when a lot of power is to be achieved with little charge. And also suitable for lighter drive and supply applications.
