DIFFERENCE BETWEEN AGM AND EFB

BATTERY TECHNOLOGIES IN START-STOP SYSTEMS

Back to overview

The start-stop system was developed to reduce CO2 and fuel consumption. In addition to energy management and a battery sensor,special start/stop batteries are  absolutely essential for the implementation. Two different battery technologies are basically used in vehicles with automatic start-stop systems, depending on the energy requirement and the required vibration or cycle stability.

 

  • AGM Absorbent Glass Mat
  • EFB Enhanced Flooded Battery

An overview of the hard facts

 

AGM battery

 

  • AGM = Absorbent Glass Mat: the acid is absorbed into the glass fleece and thus bound.
  • Running Bull AGM: Starter and on-board power supply battery for start-stop vehicles with highest energy demand and braking energy recuperation, also increasingly used as an on-board battery in electric cars
  • for middle and upper class vehicles up to luxury class
  • up to 360,000 engine starts
  • Running Bull BackUp: back-up battery for start-stop vehicles or electric cars with the highest energy requirements and braking energy recuperation

 

AGM technology is mainly used in start-stop systems with the highest energy demand, braking energy recuperation and for optimum on-board power supply stability. Primarily in the case of middle and luxury class vehicles up to the luxury class, the Running Bull AGM battery is the perfect solution. AGM (Absorbent Glass Mat) is a recombination battery.

 

EFB battery

 

  • EFB = Enhanced Flooded Battery: the cycle-resistant starter battery with liquid electrolyte
  • Running Bull EFB: starter and on-board power supply battery for vehicles with high energy requirements and simpler start-stop systems or increasingly also used as a back-up battery in electric cars
  • for small cars up to upper middle class
  • up to 270,000 engine starts

 

EFB technology is mainly used in simpler start-stop systems, generally in vehicles with high energy requirements and for optimum on-board power supply stability. Primarily in the case of small cars up to the upper middle class, the Running Bull EFB Battery the optimal solution.



*The system allows a very quick restart of the engine within 10 seconds after switching off the ignition.
*The cycle stability indicates how often a battery can be discharged and recharged until its capacity falls below a certain value.

Running Bull batteries are the ideal 12V power storage for many electric vehicles. MEGA power for engine start and on-board power supply for most additional electrical consumers. Because before the high-voltage battery can be accessed, high-voltage safety must be ensured. In order for this to be tested, control units must be in operation; these draw all the energy from the 12V lead-acid-based on-board battery.
