The 220 Ah calcium starter battery "PAG" (A 001 982 04 08 26) is replaced by the improved calcium starter battery "EFB" (A 002 982 20 08 26).
The design of the starter battery basically remains unchanged; changes involve other alloy additives and mixed elements in the interior, for example.
Properties of the improved calcium starter battery "EFB":
Shelf life of up to 15 months
Improved cycle strength
Higher resistance to vibration
In a vehicle warranty case, continue to use only the antimony starter battery "DHD" (A 000 982 13 08 26). This is also recommended for vehicles with high power requirements in the living space, typically for long-haul vehicles.
PAG = Pb-AG-CA, lead-silver-calcium alloy
EFB = Enhanced Flooded Battery
DHD = Double Heavy Duty Technology
