ΕΠΙΣΚΕΥΗ UPS - ΑΛΑΓΗ ΜΠΑΤΑΡΙΑΣ / FIXING A UPS - GHANGE A UPS BATTERY

Most of the times UPS stops to work the reason is a destroyed battery. We have to open it (4 screws to the bottom) and try to connect a 12 V battery we have at the lab. If it works again we also have to disconnect the battery and take measures with a multimeter to the battery contacts to be sure that the system charges the battery. We must measure about 13 to 13.5 voltage there. If it is ok we replace the battery with a new one , close the box and the UPS is ok again.
