Batteries in the UPS are dead. so installed new Exide batteries for 3 APC BackUP UPS ES 500 along with 2 numberic 600VA upses. Numberics are working fine and giving abt 10 min backup.
But these APCs are going to low battery mode whenever the power goes off and continuous beeping starts with amber light flashing. does anybody had this problem? What might be the reason? I even left them for charging all night. but still the same problem.
Earler its like 1 min normal beep and then battery low beep. (around 3min total backup)
With these new batteries directly the conrinuous beep starts.
Any suggestions?
