EFB batteries have a large number of possible charging cycles and provide more than double the partial and deep discharge performance in comparison with conventional batteries.ĮFB batteries are often installed in vehicles with simple automatic start-stop systems. This material helps to stabilize the active material of the plates and extend the life of the battery. Between the plate and the separator there is also a polyester scrim. Here too, the plates are insulated from each other with a microporous separator. The abbreviation “EFB” stands for “Enhanced Flooded Battery”.

Connecting the individual cells in series produces the required voltage of 12 Volt.ĭo you want to know more? You can find out how a battery functions in our article about the structure and function of starter batteries.Ĭonventional batteries such as lead-acid batteries are the most common types of battery. The required battery capacity is achieved by connecting the individual plates in the cell in parallel. The electrodes with different polarities are separated by a separator. The active material is immersed in an electrolyte, a mixture of acid and distilled water.Ī negative electrode also consists of active material, however in this case made of pure lead, and a negative grid. The grid structure gives the electrodes a solid structure and at the same time serves as an electrical conductor. A battery cell, also referred to as a plate block, consists of a positive and a negative set of plates, which in turn consists of several electrodes.Ī positive electrode consists of active material made from lead oxide and a positive grid made of lead alloy. Wet cell batteries (SLI) – proven and economicalĪ conventional starter battery consists of six battery cells.Starter batteries, EFB batteries and AGM batteries: The differences between battery types With modern, maintenance-free batteries, water loss is so low that topping up with distilled water is not necessary during the life of the battery. Just a few decades ago, the acid level in a car battery had to be regularly checked and topped up with distilled water if necessary. In spite of their different technological approaches, the latest generation of battery types have further positive features in common: They need less maintenance and are more reliable than 10 years ago – thanks to advances in battery technology.
AGM, EFB, Lead Acid: Three different battery types – many common featuresĪGM and EFB batteries are characterized by their high performance.
EFB and AGM batteries are new battery types, which cater for the increased demands of the present generation of vehicles. With continuous innovations and further developments, over the years classic wet batteries have increased in performance, reliability and versatility. Starter batteries have proved themselves in millions of cars throughout the world.
