## Questions & Answers

**Q: How many joules? 5s1500lcd**
A: The answer to that question depends on the load.  If you load the UPS lightly, you will be able to extract more energy (Joules) then if it had a heavy load.  That's pretty-much the nature of batteries.

I have an Ellipse PRO 1500 running a 55-inch TV, Stereo, and two PC-style computers. If the TV and Stereo are off, the UPS says I'm drawing 138 watts, and the UPS expects to be able to run for 41 minutes.  With 1 watt = 1 Joule/second, that's about 340,000 Joules.  If I turn on the TV and Stereo, the power rises to 442 watts, and the run-time drops to 7 minutes, 26 seconds.  Now the total energy available in Joules is down to 197,000.

I hope these two data points tell you what you need to know.

**Q: Is the LCD always on, or can it be turned off?**
A: It goes to sleep

**Q: lithium or lead acid battery? I am looking for a supercap UPS?**
A: Sealed lead-acid battery.

**Q: Does this have an alarm for when it is running on battery? If so can it be muted at all times?**
A: The 3S350 does have an audible alarm when power is removed, beeping once every 3 or 4 seconds. Unfortunately, it is not very loud.   Depending upon where it is placed you may not even be able to hear it. There is no way to silence the alarm.  For my money this is still the best value.
