Question 1

Does it have ethernet ports?

Accepted Answer

No, and generally you'll want to avoid surge protectors or UPS's with built in surge protectors that have multiple ports (i.e. coaxial, Ethernet, phone) since these devices turn on at different voltage levels. So once a surge comes in on the LINE (HOT) side of the AC outlet and the voltage has reached a certain level, the surge will be directed to both the NEUTRAL and the SAFETY GROUND, but as soon as that happens, some of the surge makes it's way into the COAX, ETHERNET, and PHONE ports and if you have something plugged into those ports then it goes into the devices. A recent study (see:  http://incompliancemag.com/article/lightning-surge-damage-to-ethernet-and-pots-ports-connected-to-inside-wiring/) confirms this. The best place to secure PHONE, and COAX connections is where they enter the house and where they can have a short (less than 10 foot connection to a buried GROUND ROD). If you secure phone & coax at the service entrance and protect your electronics with Type 3 Surge Protectors you won't need to secure the Ethernet connections.Also, it's not a good idea to rely on the Surge Protector inside a UPS as those have a higher clamping voltage generally in the 650-800 Volt range and that means until the voltage reaches 800 volts, your electronics is getting zapped. You can't plug a UPS with an MOV surge protector into an existing MOV based surge protector for compliance (safety) issues, but you can plug a UPS with an MOV surge protector or an MOV surge protector into a Series Mode filter since the filter does not rely on sacrificial MOV's. The Series Mode filter starts to work at 121.4 VAC on a 120 VAC line and it totally eliminates the surge instead of diverting it and hoping the surge can make it's way back through your house wiring to the buried ground rod from the main electrical panel.

Question 2

Can the audible beeps be totally disabled ?   Its fine for me to monitor it only via PC with USB.   I cannot have it beep at all in my environment,

Accepted Answer

Don't trust answers here unless the exact model is specified in the answer. On a BE 650G1 the alarm will beep 4 times every 30 seconds when running on battery. Pressing the power button for 1 to 2 seconds on this model will stop the beeping, but only because that will power off the unit and kill power to your devices. If you don't want the beeping, download the user manual and make sure it details how to mute the UPS; do NOT pay attention to keywords like "mutable" that APC puts on their product web pages, these are inaccurate.

Question 3

How long will it power my system while the power is off

Accepted Answer

It will allow enough time to save your work, then safely shutdown the system. It is wise to configure the power chute software with a USB connection to the PC, and your system will safely be brought down before the battery is exhausted without your interaction. Figure if you have a 300 watt PSU in your desktop, then the PC is likely using about 1/4 to 1/3 wattage while idle if no extra storage is present or expansion cards added inside. That's probably why they show us the 100 watt examples. The display is likely the top power consumer. A laptop would last significantly longer since they typically consume less than 100 watts, and rarely much more if over that.

Question 4

How often does the battery need to be replaced?

Accepted Answer

I have had APC batteries last 7-8 years, the shortest was 13 months (12-month warranty, figures!).  I have bought replacement batteries from other vendors, don't last at all.  I had a beautiful APOC SUA1500, Batteries Plus sold me 2 x SLA batteries duct taped together (yes, literally) and they were NOT made for a backup power suppl;y as they stated, leaked, corroded the entire inside of my very expensive unit!  I certainly regret that decision!  Batteries Plus said they had the APC batteries, but when I got to the store they did not, ordering them, would take a long time, so I tried their option - will NEVER shop at Batteries Plus again!

Just yesterday I had one APC battery die.  Bought new unit Dec 17, 2017, today is March 31, 2020.  Just over 3 years, their average.  No complaints.
