^ 20 pcs. na 7ah ang battery nito pinalitan mo na ba lahat??

at dapat sure kana makapag charge muna yung battery kahit at least mga 8 hours..

check mo kung may input voltage na pumapasok....

check mo din yung charging voltage....

try mo muna din na makapg initialize yang UPS bago mo lagyan nang load..
