Battery backup produces different types of noise. If your backup has a fan, that fan may respond to a case of overheating by running at a higher speed than normal which, in turn, will generate a much louder humming. If something is detached or broken, it will produce rattling inside the ups.
Why is my UPS making sound?
When the UPS is working on battery, it produces lot of heat because of Transistors or MOSFETs. To reduce the heat generated the built in fan runs at high speed. This creates buzzing sound. Also some times when the transformer used is loosely fitted, it produces high frequency sound.
Why is my APC battery backup making a clicking noise?
AVR Boost is when the UPS uses the internal transformer to decrease input voltage which may be too high. When the UPS switches to use this transformer, an internal relay makes a clicking sound. This is a normal operation of the UPS reacting to too-high, or too-low voltage.”
Do all UPS make a noise?
Every single one of them makes noise.
The towers buzz, click and hum when they turn on. They all also make electronic beeps (which can be turned off). and ALL of them make annoying buzzing sounds when the power cuts out.

How do I stop noise UPS?
Now, to stop the UPS beeping sound, find the “Control” icon in the left column. Another confirmation box will appear, asking you “Toggle Beep?”. Choose yes. Then the UPS will stop beeping.
Can UPS Explode?
Overcharging with a float voltage that is too high can cause excessive hydrogen and oxygen gases and can lead to internal dryout that, once accelerated, can cause thermal runaway – resulting in failure or even fire and explosion.
Can UPS trip?
The circuit breaker will “”trip”” or pop out if there is a severe overload on the output side of the UPS (i.e., too much equipment is plugged into the UPS). Solution: Reducing the load, then press the “”Reset”” button in. If the circuit breaker is tripped if it protrudes approximately 1/4″” out from the unit.
How do I silence my APC alarm?
Using Quick Mute on APC Back-UPS ES M-Series
How long does APC battery last?
Most APC batteries should last three to five years. There are many factors which affect Battery life including environment and number of discharges.
Is it normal for a UPS to buzz?
There is nothing wrong with the UPS you bought. The buzzing comes from the big (as in BIG) transformer, which is buzzing becouse of electrical (as in electromagnetic effects) losses in the transformer itself. There are solutions to lessen the buzzing, but they cost money, which APC spends on other things.
When should I replace my APC battery?
The battery is by far the most vulnerable and failure-prone part of your UPS. If you have your UPS long enough, you will probably have battery problems. Once every six months to a year or so you should recalibrate your UPS’s battery sensor, and once every several years you will have to replace the batteries.
How do I reset my APC battery backup?
APC Smart UPS – How to reset / restart
- Turn off and unplug UPS from wall.
- Press and hold the OFF button again.
- You may see a quick flash of the LED’s and you should hear an audible “”click”” from the UPS.
- Turn UPS back on.

Yes. The outlets will operate without any battery backup protection. Surge protection will continue to function normally. If your model has a display screen, there is a button on the front panel that can be used to mute the alarm.
Why does the UPS truck honk?
I contacted my regional UPS office and was informed that horn honking is a UPS ‘nation-wide’ policy. They said it is done to ‘facilitate deliveries.
How do I know if my UPS battery is bad?
When near failure, batteries will often begin to demonstrate strange symptoms you can use to judge the remaining life of your battery. Typically, repeating alarms, flashing panel lights, and strange terminal displays are all symptoms of a failing UPS battery.
Can APC UPS catch fire?
Fires from a UPS are very rare. They do have lead acid batteries, that can catch on fire, esp if not changed when needed.
How do I check the health of my UPS battery?
To test any battery, it must be fully charged first. After charging, the surface charge must be removed and this can be done by briefly turning on the headlight, for instance, then let the battery sit for a couple of hours. After this, the battery is ready for both tests.
