I purchased my AVR1000 almost 7 years ago, and after a recent outage that completely drained the battery (I wasn't home when it happened, but my machine was on), it is just now acting "weird."

Tech support quickly sent new batteries and it worked great ever since!

Awesome battery backup

This battery "back up" has failed me for the last time, Admiral CyberPower.

This is not acceptable given I have other brands of UPS that are 12+ years old that have gone through multiple battery changes but still work even if the battery has been depleted.

Just dont overload them or you will kill the battery fast.

A good battery backup for general office use, but not recommended for computers.

It holds up for small power bumps (the APC would die out as the battery was dead after 2 years, other units lasted less than 6 months).

This battery is worthless

I needed a good battery backup for a storm team computer and this did it.

2020 - power went out july 12 2020 - dead batteries

Your battery dies everything dies

Battery back-up is good for computers, tv and cable boxes, radios, and all other types of devices

Support suggested a likely worn-out battery issue and recommended replacement batteries

After I got my gear plugged in, the display on the 1000 said I had enough battery power to run my PS4 in rest mode for 10 hours

Usually the battery will go bad and you can replace them

Battery died on the second outage

Found out the 4 new batteries I bought were also crap (probably been sitting on the shelf for years)

Now in Sept of 2020 the batteries are failing which is to be expected but this unit will totally shut down even with normal levels of incoming line power available.

When the battery starts to fail, the UPS will start to fail, even when it is connected to power.

I have had it for 3 years and it only experienced a few power outages but has already lost all battery

The battery back up doesn’t work at all.

Easy to setup and the Synology shutdown part was also easy in that it autodetected the compatible battery backup and just had to enable it.*Update*Yesterday had our first big snow storm of the year and had a power outage.

Battery just died yesterday and I just realized I’ve had it for a little bit over 5 years

it's a bad battery but STILL

The UPS itself (not the battery) died within one year and a half

One other feature of note is the lack of replaceable batteries

Once the batteries start to fail, though, the manufacturer makes it as difficult as possible for the owner to replace them

The unit is pulling 18.3 watts with completely dead batteries.

excellent battery back up system

The bad battery was a little bit of a hassle, but customer support was good and the unit has otherwise worked well.

The CyberPower does not feature a user-replaceable battery

No interruptions, battery will power both units for a fair amount of time.

I don't mean that the battery is messed up, or the sin wave is out of sync, I mean, when the power goes out it just sits there and looks at you like nothing is wrong while all your equipment experiences a sudden power drop

Indications showed batteries were depleted.

Provide battery protection and surge protection

I suspect the batteries inside are cheap.

It also reported that the battery backup would shutdown the NAS if the battery started to deplete.

I replaced the batteries on these and they still didn't work

Despite having fresh (4 months old) batteries, a recent power outage not only resulted in the UPS basically turning off and not providing power to what was connected to it, but now I cannot turn it back on.

But I did use it to power my cellphone up and it did not drain the battery

battery not working

It will stay on battery until it runs the battery dead

All required me to open the unit to disable the AC alarm(cut the circuit), and most had replaceable batteries, but none other than CyberPower made it easy and truly lasted three years on a set of batteries

Battery depleted within seconds despite tiny power draw

I also use them at work and have found that they work well and the battery is easily replaceable by almost any battery shop and at a god

Good battery

but a full battery is available.

I purchased the premium model CyberPower UPS 2-1/2 years ago, and the batteries in it have started leaking

A good battery backup for general office use, but not recommended for computers.

I've used APC in the past, but that brand had a tendency to kill their batteries VERY quickly.

I suspected the battery had been exhausted - as it should be, but the house had power and the until was offline

Excellent battery backup and surge protector for my WiFi and TV

I recieved with the batteries dead

When I opened the unit's case, I found the upper battery was leaking, which caused the surface it was sitting on to be bubbled from the acid

The battery of the DOA UPS worked perfectly on the one that works, and the battery of the one that works doesn't change anything on the status of the DOA UPS

These units worked flawlessly for the time that I had him, batteries died two years after purchase, but did not care to replace them

This is a solid battery backup, saved me several times in bad storms or outage where it could have damaged my hardware

Never knew how much I would need and love a battery back

With my configuration I am actually able to run the devices for 50 minutes before the battery is depleted.

I want to a battery store and replaced the battery but that only worked for a few years.

After doing some problem solving, I kinda figured it was a dead battery, called Cyberpower tech support

I generally replace at that point rather than face a fast dying battery on an outage

After 8 years my older CyberPower backup stopped working, battery dead, alarm signal etc

This UPS has a pair of 8 Amp/hr lead-acid batteries.

If the battery is depleted, the unit will remain powered off completely and not provide power to any outlets - even the outlets that are not connected to the battery.

We have also accidentally overloaded it with a space heater and the battery responded with a loud beep noise and I remedied quickly

Battery is still good and holds a good charge after three years

The battery inside is not incapable of holding a charge under even small amounts of load.

I ordered a new battery for my old one as well and will move that battery to my old pc

It did not work as a battery back up for very long if at all.

Only 4 stars because of the dead battery issue, will change to 5 if the new ones fix the issue.

I made sure it is plugged in on battery side and the battery is good

If the power goes out now the battery is instantly dead

The unit should not power up at all if the battery is completely dead

Great battery life, has handled several power surges already without so much as a flicker to the connected devices.

After 8 years my older CyberPower backup stopped working, battery dead, alarm signal etc

this lines out the power, great battery back up...fantastic price

I do not expect it to provide backup in a power loss event without good batteries but it should continue to work as a source of power and surge protector even without batteries as my old APC does

When it arrived the batteries were dead

The panel shows the batteries are fine, and that the load is light, but interrupt power to the unit and it no longer switches to battery, it just dies altogether.

Looks like faulty batteries.

After over two years the battery is still working properly.

Although mostly still holding, it seems the batteries were getting weak.

I first noticed that the battery had gone bad (within 2 years) when after a power outage I only got about 2 minutes of up time.

These units worked flawlessly for the time that I had him, batteries died two years after purchase, but did not care to replace them

Part of the description states leak free battery

The machine works as it should and it's very easy to install -- just plug things in.

Works as it's supposed to however I did not realize the battery was already attached.

It works exactly as we expect.

Substantial time (as well as having bought additional wifi adapters/dongles) trying to determine why wifi and dual monitors would not work

I called OG&E to complain and they told our electricity was terrible (which everyone in town already knows) and they would not accept responsibility for my television issues.
