Switching ups 24x7

[maverick786us]

I recently purchased an APV 1.5 KVA smart ups, which provide enough juice for my printer and router. Now my printer is on only when I use it. But I purchased an expensive Asus 1900 rt dual ban router which is on 24x7. I connected it with the UPS for safety against voltage fluctuation. For that I might have to switch on the ups 24x7. Now the question is, does switching on the UPS 24x7 reduces its life? Specially the batteries?

The avg battery life on a UPS is 3-5 years I believe....

I've never heard of anyone turning off a UPS, why wouldn't you leave it on 24/7. I probably get about 4-6 years from my batteries and then I just typically replace the unit unless the battery is easily replaceable and cheaper than a new unit.

Thanks for the information. I will keep it on 24X7 to protect the router. The onlything that I will make sure is the battery isn't completely drained out during the power outage. So if there is any power cut, then I will avoid printing and scanning. But the router doesn't consume any power, therefore will keep it on.

Err... printer the powered ports of a UPS? Bad idea, doubly bad idea if it's a laser printer.

Better to just have the printer on the surge protection side.

That is the reason I replaced that 1KVA UPS with 1.5KVA which provides a power of almost 800W, while my LED printers maximum power consumption is 333. Now I am using my old UPS for my PC. The 1KVA UPS couldn't handle the load of the printer, when the printing process takes place or when printer initializes while starting. This one is able to take the load, although sometimes it beep for some seconds. But still is it safe?

Still a bad idea, laser printers are very spiky in their loads, particularly when it's warming up the fuser. You really don't need a printer on the battery side. I mean if there's a power outage you're only real concern is getting everything shut down safely, not finishing a print job.

Yeah those things eat up some wattage on startup, always dims the lights when they turn on, spikes to 660w

Yes I agree, I will switch it to the surge protection. But I hope if the printer is on, and someone accidentally switches of the main power, will it crash the OS, firmware that is installed in the printer?

I happened to face this issue in my old HP 7500 All in 1 series printer. Although it was an inkjet, but couple of improper shutdowns (accidentally) resulted in an error in the firmware, where it happened to display some binary error code in the screen. Although I was pleased when, I sold that printer.

With my new printer, i decided, that I will always use a UPS.

That 7500 failed because HP is junk

You will find no UPS manufacturer that recommends placing laser printers onto battery power. Their transient loads can lead to damaging the UPS, increasing harmonic distortion which may cause instability in anything plugged into battery backup, or commit suicide itself.

Leave the UPS running at all times, it will only intervene when there are power events and it will keep the battery charged like an alternator in a car which also uses lead acid batteries. These things like to be at 100% for the life span. In fact, letting it sit and lose charge decreases its lifespan. You can also run tests periodically with the computer if it's turned on and plugged into the USB/network.
