CAUTION
！
Perform a battery test periodically to check if the batteries have deteriorated. Using a deteriorated battery may result
in battery leakage and, in the worst case, smoke, a fire or a disaster. When the batteries have deteriorated, replace
them.
Run a battery test following the procedure below. If the UPS has performed a backup operation within 12 hours prior to the test, the
result may show an error. In such a case, conduct the test when the UPS has not performed a backup operation within the last 12
hours.
