Question about HP R1500 XR (204404B31) UPS System

Open Question

UPS suddenly inoperable

I purchased a rebuilt XR1500R UPS to use in my home theater rack.

It was too loud so I replaced the fans with quieter ones and ran them at half speed, and added 2 additonal fans inside and a third one mounted to the rear, to improve airflow while still keeping the sound down. I'm running the two main fans at 6 volts and the other 3 at the full 12 volts.

After setting this up, I left the machine to run on AC with no load, and when I checked on it about 12 hours later, the keypad had locked up, every indicator light was on, the internal fans were shut off and there was no power available at the outlets.

The only way to get the lights to turn off is to disconnect both AC and the battery, but plugging in the AC or the battery and pushing the on switch causes the lockup again.

At this point, the device is unusable.

Any suggestions for repair would be accepted with much thanks.

SOURCE: With the battery is switch

One of the converters is fried and acts as a short . This in turn activates the onboard protection.
The unit must be dismantled to test and identify the failed parts. Very good knowledge of switching psu's is mandatory to do that so this job should exclusively the domain of a pro.

Will not turn on


If the battery is dead you will need to replace it with a new one, preferably, before the UPS will turn on again.

Yeah, its better to buy a new UPS. But hey, if you have the time to search for it go for it. If you call the MFR and just ask for parts dept, then tell them the part no on the fan and order it from them. Hope this helps

It is probably a bad battery. They usually don't last much longer than 2-3 years. You could try replacing the battery, but I would suggest just replacing the whole UPS with a new model.

My BE500U backup UPS ES is emitting a continuous alarm. Is this a dead/dying battery issue or something else?

I found cooling fan was seized, causing overlheat, and loud whistle. WD 40 eased up the bearings, but I expect I will eventually have to change the fan. Mine is an APC XS900.

My suggestion would be to replace the battery to make sure the battery is not shorting out the UPS. If you can't do that, take out the battery and then replug the UPS back in.

If you still get the same results then that means the main board inside of the ups system is bad and you would need to get a new UPS system.

I need a replacement cooling fan for my smart ups 1400. It sounds like a freight train under my desk, and I cannot go buy one off the shelf.

well it could be your fan is dirty that why it makin lot of noise the problem why the ups i quite runnig the fan it becoz it try to cool down the temperture.. as i know your ups i puttin under the desk there not much ventiltation and the floor is dusty.. to be right you hav to place somewhere that is cool and more ventilation.. so the ups won't always be makin sound.. well replace a cooler fan would cost u much and also even u replace the fan it matter of time when your ups trap more dust and evently the ups might givin noise plus your ups might hitting not juz the fan it might be you hardware havin the problem or the battery is easy spoil within 2 years time or less

UPS Batteries bulging and not working

There are several reasons for a buldged battery.

Mainly - older batteries do that. These batteries are meant to be replaced every so often. The r1500 is an older model, and therefore if those are the original batteries, it's probably normal.

My unit the battery is about to die also, I will be replacing it soon :-).
