A1 Premium EFB Maintenance-Free Battery (MFD23EF) 4032EFB

An Enhanced Flooded Battery (EFB) is designed to support idle stop start and smart alternator technology. When it comes time to replace the battery on many modern vehicles, it is important to replace it with the same type to avoid warning messages and shortened battery life, even if you don't use the idle stop start feature. EFBs deliver better cycling performance and accepts higher charge rates when compared to a standard Calcium battery. They are designed to meet the specific requirements in vehicles originally equipped with an EFB.
