Traditional UPS battery test maintenance testing methods: 1. the multimeter to measure battery terminal voltage proved measured with a multimeter float UPS battery terminal voltage is unable to determine whether the old battery has failed. So generally offline or online measurement of the battery terminal voltage, measured battery terminal voltage is about 12V (for 12V battery is concerned), the minimum can not be lower than 10.5V. 10.5V battery voltage is insufficient or the battery has failed. If the battery charge after charge or activate the rear end voltage still can not reach 12V, that is a dead battery. 2. Test whether the moment of starting the UPS battery output-current characteristics of the battery back-up UPS mains power to the inverter switching time requirement is less than 7ms, generally designed around 4-5ms. That is, once the electricity supply interruption, UPS batteries must output load current is required in less than 4-5ms time. Some failure of the battery terminal voltage and capacity to meet the requirements, but can not reach the high-current discharge current requirement in less than 4-5ms, also failed battery. UPS battery output-current characteristic moment only in closed mains to test battery performance without knowing the situation there is a certain risk, is generally not carried out. UPS battery is not instantaneous output current is sufficiently large, generally due to battery discharge caused by the prolonged absence of regular discharge or periodic discharge of UPS batteries basically non-existent problem. UP 3. UPS discriminating method discriminating S battery capacity and the capacity of the conventional battery UPS batteries discrimination in general the same way, the whole group from the UPS battery shunt resistor wire on the power supply system, with eight or ten hour rate constant current discharge, and then first to reach the discharge voltage of a monomer of the UPS battery discharge time and current, to calculate its capacity.
