We have several SUA750 UPS, when we replace new batteries and gave a load to test, After few minits It alarmed continuously like overload. Need to reset anything. What is the procedure for battery replacement?

[BillP]

we have already calibrated the UPS, according to the standard procedure ,But the problem is still on going . The rated UPS(SUA750I) capacity, around 540Watts, we applied dummy load, around 300Watts. after few seconds, battery level led bar flashing and contineous beep sound.

Calibration is done according to the instructions but problem remains.
