Picked one of these up for the kids during their sale last year. Works great in maintaining power so they can online game.

Some parents just don't care about their kids getting a pure sine wave signal and it's ripping this country apart.

This thing uses lead acid batteries? Gross. Get with the times, CyberPower.

You are aware that lithium aren't the best at charging and float 100% This is why not many lithium ups are available unless you want to talk about offgrid which cycle through charge and discharge cycles consistently. But lithium ups are also very loud fan wise. Keeping the battery at 100% comes at a very high cost.

Li-Ion degrades modestly quickly being kept at 100%, yes. For the most part, newer UPSes are using LiFePO4 batteries, which are essentially fine being kept at 100% don't have the fire risk of Li-Ion and degrade very modestly over years.

With lead acid batteries, you will be replacing the them probably every 5 years, even if you don't use them at all, and sooner if you have frequent discharging. Neither of the lithium chemistries care about actually being used.

Most importantly, this item is $7,000 and can put out 8,000 watts for 11 minutes. Meanwhile you can buy a LiFePO4 power bank for $1,000 less which would power 8,000 watts for 1.5 hours, and the batteries will probably outlast the inverter. Granted, these aren't really designed to be UPSes, but this is why people look at "deals" like this and wonder this costs so much for what it does.

Is it that important to have one of these for devices that cost less than half of this product?

do you really need to say more besides enterprise class? The two most expensive computer hardware class is 1. Apple 2. Enterprise followed by Gamer coming pretty close to the two, but not there yet. This UPS is enterprise class. At 8 thousand dollars, i would not recommend it, and would tell people you can get a pretty insane LiFePO4 10kwh off grid system, and pull whatever your using the ups off grid most of the time being charged constantly on top though a Auto Transfer Switch inverter, which is why i said off grid solutions. It wont be "Enterprise" class, but it will play Crysis/Minecraft which is the most important right?

That's waht I was thinking too. This isn't something you want.A decent LiFePO4 is cheaper and last much longer.
Besides that, what would you need 8000 watts for at home ? In a server rack ?
