That's probably a reseller account.

They downplay deals so they can dissuade people from buying stuff they're trying to flip.

I would love to see the Li-On battery technology 'trickle down' faster to the consumer market. I've been experimenting with using a USB power bank and a USB 3.1 PD development board to power my various DC networking components.
The elimination of DC -> inverter -> AC -> router power brick -> rectifier -> DC has looses at each step.

any good brand/deal on a battery for these things? I have one that's sitting as the battery I'm pretty sure is bad/dead.
Idk if it's the best deal but I've bought and used a number of Weize 12v 9AH (F2 terminals) in my cyber power upses . Got them on Amazon for $43 for two. I'm happy with them.

They're likely not pure sinewave but for a lot of equipment that doesn't matter. I still use an older one that has a new battery. Runs other stuff just fine.
For home lab I use a lifepo larger system.
Yeah I haven't personally needed pure sine wave for anything. I use them on my networking equipment and monitors and such. No issues with square waves. I think PC PSUs can be touchy about it tho. Maybe if you have to run on battery often then it might decrease the lifespan of the equipment. Remember tho that simulated vs pure sine wave only comes into play when your AC mains disconnects. It's pure sine wave while on 120V

I've gotten into 18650 builds myself and am planning on a solar / lithium whole house build some day. I just know I'll burn the house down tho. But I've got my spot welder lol

Not recommended to connect to a sump pump, since they will exceed the 900W power rating.
Yeah I tried hooking up a poop pump to one of these. A beefy one too 1500VA series. It immediately alarmed and shut off.

My sump pump has a marine battery as a battery backup. Same size as a large car battery. This battery backup has saved my basement from flooding numerous times.

Consumer Grade UPS's like these aren't intended to be used on equipment like sump pumps and poop pumps that have motors that cycle power pretty hard when operating. As you discover. Even with a beefy UPS.

prefer lifepo batteries for inside and there's already plenty of them. They're just larger batteries ($$) and some aren't fast enough to switch on power outage. But that's also improving. I use one as a giant ups and it's been amazing. My home lab can run for a long time.

Have a synology nas without an ups at the moment. Wondering if the cheap model is good enough to gently shut it down, if I'm here when it goes out?

To be honest, I did expect a deeper discount for the 1500VA being it's a refurb plus the non-sine wave version. This is comparing to the unicorn deal that Staples had for $170 however.

Also, buyer beware that Woot is passing along misleading information for the 1350VA [woot.com]. Checking the model number against the manufacturer website [cyberpowersystems.com] says that it's a simulated sine wave, not a pure sine wave that Woot says it is.

Looks like all the true sine wave are gone. Simulated is OK but not for my purposes.

I'd love to see APC/Cyberpower etc come out with a LiFePO4 battery, as they last much longer before replacement and are way lighter. Perhaps we'll see more of the fabled solid state hit the market before long. I've already seen a few consumer grade solid states for sale but their price point is still a bit high.

which gian UPS
I gave up on these lead acid UPSs a couple months ago. We had a lot of bad storms here in Texas the first half of this year and our power was going out all the time. My cyberpower and APC batteries would keep my equipment running for about 9 minutes total. That's with one of the cyberpower 1500s backing up only my desktop PC case, another running my monitor, another running network equipment, etc. NINE minutes even with a fairly new UPS with a colorful screen etc. Out of frustration/desperation I splurged on an ecoflow delta2 for $400 and it will run my main PC, monitor, and local network equipment for 4 hours. FOUR hours. LiFePO. How do I know it'll really run for 4 hours? Because we had a 6 hour power outage a week later (tornadoes) and I eeked it out to 5 hours by shutting down all but the most critical apps. I ordered the delta2 regular spare later that day, and then a delta2 + spare combo for my server. Delta2 = 4 hours at $400. My last cyberpower 1500va = 9 minutes at ~$130. It just does not compare. I now have 8 lead acid UPSs sitting outside on a dead freezer. Absolutely no problem with the switchover in a power flicker / surge / whatever. Not trying to shill for ecoflow... I'm sure other LiFePO products will do the trick.

edit: just looked under the desk and reminded myself that I actually still have my newest cyberpower 1500va inline between my PC and the ecoflow delta2. So I haven't tested failover without the lead acid UPS in the mix.

Would either of the two simulated sine wave models (1500VA) be ok to run a regular sized refrigerator for a little while? Or does it HAVE to be pure sine wave for that.
You need something like a river 2 pro to run the fridge. That's what I threw on mine. Powers for >5 hrs but that depends on your refrigerator. After 5 hours I fired up the generator and recharged the river 2 pro. Charging time is a little over 1.5hrs if I recall correctly. I got my river 2 pro for about 300 on sale.

Anybody know if they also refurbish the surge protection portion? I'm not sure what surge protection technology these use. For example, regular surge protector strips use consumable MOV's and I wouldn't be surprised if these did also but I really don't know.

My consumer UPS have never been able to report a bad battery. The only way to tell is to unplug it with a load to see if it keeps you powered.

For 3 years, it seems like it's time to replace the batteries and you're good as new.

Plugin a pc with the cyber power software and run a battery test. If it turns off, the battery is completely dead. I had a CP 1325 that did the same thing. Threw in a new battery and it's working great.

If it has usb it will work fine. I've used a variety of UPS (apc and cyber power) with both of my synos

I keep my gear on backups. However, all backups seem to fail eventually. Likely just the battery, but it's hard for me to tell TBH. The devices don't really distinguish why they are screeching uncontrollably.

I've gone to Amazon or eBay for battery replacements. Does anyone have a good lead on trustworthy battery replacements to Cyberpower? I have at least 2 that need some new juice currently.
