Is the battery used with the automatic start-stop type the same as the battery without the automatic start-stop type? It's actually different. The battery with automatic start-stop type, in fact, this kind of battery has a function that can provide a large current instantly and can quickly and repeatedly charge. Ordinary batteries (lead-calcium batteries) do not have this function, and relatively speaking, batteries equipped with automatic start-stop functions have a life span that is 2 to 3 times longer than that of ordinary lead-calcium batteries. At present, there are two types of high-efficiency batteries (start-stop batteries) on the market, one is AGM and the other is EFB. AGM is mainly used in European models or German models, while EFB's start-stop battery is mainly used in Japanese cars. Although the names of these two batteries are not the same, the actual functions of the batteries are also the same. In cars, the general specification of 12V (70AHCCA720) or higher is generally recognized as a high-efficiency battery (start-stop battery). The standard battery below 12V (65AHCCA550) is generally recognized as an ordinary battery (lead-calcium battery).
