Answer / hemant nimbalkar

There is no need to turn off the ups or remove the
connection.We can check spec. gravity at the time of
battery charging.Spec.gravity is checked by hydrometer.Just
immersed the the hydrometer in each cell which have to
mesure.Press the rubber handle &take some electrolyte and
mesure sp. gravity. the value should be 1200-1250.
