AGM stands for absorbent glass mat. These battery types are currently being installed on the new stop start vehicles and other luxury vehicles on the market. They can also be very useful on performance cars that do low mileage or vehicles that have heavy electrical demands.
Stop start vehicles are becoming more and more popular due to the EU fuel emission campaign. The growing demand for AGM batteries has increased 14% in just 2 years in the United Kingdom alone.
The main car manufacturers using this technology at the moment are Audi, BMW, Mercedes and Nissan.
