Clicking Back-UP Pro 1000

[Anonymous user]

About a year or so ago, we purchased a few Back-UP Pro 1000 units and up until now they have been working fine. Lately, for one unit, when anything is plugged into it, it will start clicking usually every few minutes. Also, before anything is plugged into it, it will give me a time of 860 minutes remaining but when something is plugged in it instantly drops to 45/ 47 minutes.The only thing that we plug into the Backup Battery side of the Pro 1000 is a surge protector that connects to a PC, 2 monitors, and a phone charger.

We've tried plugging the Pro 1000 into other outlets on the wall, plugging our surge protector into either the 'Surge Protector' side or the 'Backup Battery' side of the Pro 1000. We've tried letting to Pro 1000 charge over night before we plug anything into it but it still clicks and drops in coverage time.

Has anyone ever seen this? Is there a fix for this?

Hello PinkRatchet,

What is the exact part# of this UPS?You can get the part# and serial# of the UPS from the white sticker with bar codes at the back of the unit. I recommend that you plug the PC and the 2 monitors directly to the battery backed up outlets of the UPS and the phone charged should go to the surge only side. Surge protectors filter the power for surges and offer EMI/RFI filtering but do not efficiently distribute the power, meaning that some equipment may be deprived of the necessary amperage it requires to run properly (more here).

The runtime this UPS provides depends on how much the battery charge is and is inversely proportional to the power consumption of the devices plugged into the battery backed up outlets (usually in watts), use the LCD screen of the UPS to find out how much the power consumption is of those devices and then check the battery runtime chart that is on the technical specifications webpage of the UPS. The UPS clicks probably because it sees something on the input voltage that causes the unit to switch to on battery operation, that may also be the reason why the runtime is dropping.
