Battery occupies a very important position in the UPS and EPS power supply equipment, how to properly maintain the battery, so prolong life, to maximize the effect? Here I will describe briefly.General UPS / EPS power supply 12V battery capacity, mostly in a, float voltage between 13.5V to 13.8V, the float voltage is too low, the battery can not be charged, the float voltage is too high, it will cause over-voltage charging, when the float when the charging voltage exceeds 14V overvoltage considered that charge, over-voltage charging can cause electrolyte in the water is separated into hydrogen and oxygen overflow, is what we usually see bulging battery, the battery life is shortened. Charging method should preferably be segmented current charging, i.e., using a larger initial charging current, charging time to a small current stage of charging switch to a smaller current, the charging is generally designed 0.1C . Such a charge mode though healthy, but not easy to maintain. For this ser...

![eps power supply charger direct impact on battery life]( "eps power supply charger direct impact on battery life")
EPS in the charger constant current constant voltage charging method commonly used two-stage charging mode or constant voltage limiting. Charger is good or bad influence on the larger battery life, you should ensure that the maximum charging current does not exceed the permissible value is equipped with a battery float voltage batteries comply with the recommended values, such as temperature compensation is better with high frequency ripple current should be controlled at a lower level. Of course, you can use other charging methods, such as cyclic charging, auto BC - float control, but the control is slightly more complicated. Mains is normal, EPS in the charger usually also need to control the system power supply. Chargers should have high reliability and good self-protection, should be able to adapt to a wide range of input AC voltage to ensure proper charging power in a variety of harsh environments and for the EPS control system power supply. Due to the power charger is small and m...
