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

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.

Does it beep on outage and can you mute it?

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.

What is the surge suppression/protection rating (in joules)?

316 Joules. It's written in the manual under specifications.

What is the maximum operating temperature of this device?

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.
