Tags: Will UPS batteries be connected in series to affect their capacity? Q: Will UPS batteries be connected in series to affect their capacity? Why is the efficiency of UPS power supply only 80%, is it caused by series connection? Answer: The series connection of UPS batteries has no effect on the battery capacity, but the voltage is accumulated. For example, if four 12V100AH u200bu200bbatteries are connected in series, their voltage is 48V, but the capacity is still 100AH, without any change. 80% of UPS power efficiency is not affected by the series connection of batteries, but the defect of the inverter itself.
