Hi,
I have bought a STM1000l,
When the batteries are at 100%, this noise start and it's go ahead every 20 seconds (you can hear it at the start of this audio file and 2 times after around 20 and 40 seconds).
It is possible to hear it also when the smart UPS is off, but with the current attached.
Is there anyone with this model? is there this noise?

The seller has sent another ups, but there is the same noise..
