Assistance For Smart UPS SUA1000XL problem

[Anonymous user]

My UPS creating problem with charging and load i have installed two batteries. I using its after three month of shutdown.  I am using it from Last two years.

Some time battery charging indicators blink some time remains static.

Its making too much clicking sound. Its also make clicking sound even it totally poweroff. Red wire connected with positive terminal and black wire to negative terminal, while both batteries -/+ connected to each other. 

Please help guys.

Your Smart UPS is likely in need of a runtime calibration if you have installed new batteries. The blinking battery charge level LEDs indicate that the UPS believes it can only power the load for a short period of time. (By default this is two minutes, but it can be adjusted through UPS management software. You may want to check that value.)

To perform a runtime calibration, you'll need an outlet strip with a switch, properly grounded electrical outlet, and an electrical load of some kind that runs to at least 30% of the UPS's rated capacity. Purely resistive loads (not computers or motors) are best for this, and incandescent light bulbs work well.

1. Safely power down the load to which the UPS is attached. Since the UPS will be away from the load for a while, you may want to put another UPS in place if the load is critically important.

2. Place the UPS in a location where you can work with it easily. Plug the outlet strip into the wall outlet, and the UPS into the outlet strip.

4. Turn the UPS on and let it charge the battery for at least eight hours.

5. Connect your lamps or other dummy loads, turn them on and give them a few minutes to stabilize. It's important that the load remain nearly constant while the UPS is being calibrated.

6. Switch the outlet strip OFF. The UPS should begin carrying the load. Allow the UPS to do so until it shuts down.

7. Allow the UPS to recharge its battery for a minimum of eight hours. Place it back in its original location and reconnect the equipment that needs to be protected.

Note: if the batteries in the UPS have gotten bad enough, it may not be possible to perform a successful calibration. At one time, APC provided a calibration key to solve this problem. I'm unsure if they still do.

My understanding is that calibration using your manual procedure should always work. On some of the older UPSes, issuing a software calibration command would be ineffective because the estimated runtime is too low.
