What is the difference between EFB batteries and ordinary batteries?
2 Answers
EFB batteries differ from ordinary batteries mainly in internal structure, performance, service life, and price. EFB stands for Enhanced Flooded Battery, a type of start-stop battery. Based on traditional battery technology, EFB batteries can adjust electrolyte concentration by adding distilled water, thereby improving deep-cycle performance. Relevant information about car batteries is as follows: 1. Introduction: Car batteries, also known as storage batteries, are a type of battery that converts chemical energy into electrical energy. Typically, the term "battery" refers to lead-acid batteries, which are mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte. 2. Working Principle: It uses lead plates filled with sponge-like lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and 22-28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharge, chemical energy is converted back into electrical energy.
I just drove a Hyundai and noticed a big difference between EFB batteries and regular ones. EFB is specifically designed for start-stop systems, while regular batteries tend to fail under frequent starts because they're not tailored for that kind of load. EFB batteries have thicker plates, allowing them to handle deeper discharge cycles, and generally last one or two years longer. Although they cost about 100-200 yuan more, it's worth it in the long run. After switching to EFB, my start-stop system works much smoother, and I don’t have to worry about the engine suddenly stalling. Maintenance isn’t much different—both require regular checks on fluid levels—but EFB is more reliable. If your car has a start-stop feature, upgrade ASAP for a more worry-free drive.
