Question 1

Is this ups expected to last longer than 3 years? is the battery replaceable? is there a way to disable beeping?

Accepted Answer

Thank you for your question.  Yes, the UPS is designed to last longer than 3 yrs. It comes with a standard 3 yr. warranty. The battery inside this PST5 UPS is VRLA and depending on environmental and use factors will need to be replaced typically in 3-5 years under standard temperature environments and following recharge guidelines in the manual.  We do offer Lithium in our PSI5 series that has 2-3X the life of VRLA and takes the heat even better.
Beeping along with the LED color is alerting you to draw your attention to the unit as a warning indicator. Page 17 of our manual highlights 1 beep/sec rate is notice that the load devices attached to the output of the UPS are exceeding the UPS rating and one should reduce the load plugged into the UPS.  2 beeps/5 sec or 3 beeps/30 seconds indicate the battery is week.  Charge the ups or replace the battery.  We have not designed this unit with disable alarm functionality.
Yes, the battery is replaceable.
