FY series charger apply to the size of a series of car batteries slow, fast and forced to start charging, and so on. This series is used in slow, fast electric ion decomposition principle, there are a variety of high-temperature decomposition of the Department of battery used car battery for optimal results. As a result of multi-rectifier, rechargeable (12V-24V) battery, 12V, 24 voltage, current show that the battery can understand the situation and has assisted with imposed start, and so on.
