## Questions & Answers

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

**Q: Does it beep on outage and can you mute it?**
A: Yes it does beep.   You can however mute the device during an outage by pressing the button on the front.   I have the 850VA and purchased in 2021.

**Q: What is the surge suppression/protection rating (in joules)?**
A: 316 Joules. It's written in the manual under specifications.

**Q: What is the maximum operating temperature of this device?**
A: Operating temperature range is 32-104F (0 to40C).  Most applications are used for protecting desktop computers, gaming consoles, wifi routers and other electronics, typically in an indoor setting.  Please contact our Vertiv for other uses.
