CyberPower RB1290 UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/9Ah

These replacement batteries do quite well in my CyberPower UPS units that I have spread all over the house (it might be cheaper in the long run to get a whole house UPS, but I never have that much unallocated funds available at one time). They have ridden my computer and other electronics through many midwestern storms, and since the feed from Indiana Michigan Power is inconsistent at best, these things tend to get a lot of exercise in my house. They are not the cheapest available on Amazon, but I'm afraid to try these off brands that are advertised at lowball prices. For the cost of replacing my computer or entertainment equipment, I'll pay a little extra and get what I know works.

I'll start by saying that getting this battery in and out of my UPS unit was not hard, but it was awkward and bruised knuckles based on the tiny wires they put in there and the difficulty of just yanking. Cyberpower is fine for most uses, but when a battery goes out, those plugins do not even function as a surge as there is no power to them, and there isn't an easy way to shut it up without just pulling the battery out while you wait for a replacement. I wasn't a fan of the whole battery just died problem as there was no real preamble to it.

I've had the CyberPower 1000 for 2 years and this is my second battery. I may be incorrect, but the battery last from 1.5 to 2 years; IT MAY BE THE WAY I AM USING IT. I experience maybe 10 Events per year and I would not have known that unless I checked the battery display for the number of events,...I never realized the power was interrupted. I give this unit a 👍 BIG THUMBS UP. I use the UPS to power & protect my OLED TV, my computer and a mobile phone charger. My OLED and computer combined are a$6,000; that is not unusual. Even if you have a MODEST computer and TV, you're still looking at a minimum of $1,000 of equipment. If you get a NASTY,...nasty power spike, you could easily loose both pieces of equipment. For the average person, you can get a CyberPower UPS for under $200.

Battery arrived well packaged and in good condition. Took 5 minutes to remove the old dead unit and put this new Cyberpower-branded battery in my 6 yr. old 1000 w. unit. Slid right in, power cables connected zippy-zap and sealed the case up. Plugged in and power on, battery already at 70$ and now charging up. Most painless install I've done in a long time. Hope this battery lasts as long as the old one.

Photos i included: The battery that says CyberPower, that's the replacement battery i received from Amazon. The other battery is the original battery that was in my UPS. (The UPS was bought brand new) Thought i would mention this as it's odd that the original battery doesn't say CyberPower but the replacement battery does. The 3rd photo is the UPS with the battery cover removed. There's two cables that need to be unplugged to remove the battery. And reconnected to the new battery when installing the new battery. ____________________________ I own the CyberPower 1000PFCLCD, UPS. I think there's more than 1 version of this UPS model. I think this is the newer (last version) of it, because mine doesn't look like this: https://www.amazon.com/dp/B00429N192 Mine has no USB, no tilting LCD screen. But the replacement battery works just fine. ____________________________ FIRST THING TO KNOW ABOUT THIS UPS: You know when the battery is dying because having a dying battery causes the UPS to randomly beep, display an error message on the LCD screen then randomly turn off and cut off power to your devices that are plugged in. And this specific UPS model was at the point that it would only stay on for 3-5 min before it cuts off. NOT GOOD because my PC was plugged into it. I'd turn the UPS back on, turn my PC back on. Few minutes later, the UPS would cut off power again. I contacted CyberPower and they told me to replace the battery. So i'm not 100% sure but i think this UPS can't be used without a battery. I think if you removed the battery it may not turn on at all or if it does turn on it'll randomly cause an error then shut off and turn all your devices off. So YOU NEED to replace the battery if you want to use the UPS. ____________________________ REPLACEMENT BATTERY: GOOD NEWS! This battery works! I replaced the battery with this new battery. I charged it 100% (according to the LCD screen on the UPS) So far the UPS is staying on, no errors (Both while plugged into the wall outlet and when unplugged). BUT i will NOTE, i am testing it without any devices plugged in. So far it seems fine though. ____________________________ NEW PROBLEM. Maybe, Maybe not: How long does this UPS run with no devices plugged in? I'm not sure. Is it 140 minutes? OR is it 200 minutes? I am testing the UPS with new battery replacement, charged to 100%, WITH NO DEVICES PLUGGED IN. With the UPS plugged in, the LCD screen said i had 200 minutes of battery life. I tested removing the UPS plug from the AC outlet to see how long the battery would last AND to test if it even works. Then i noticed the LCD screen started to countdown from 200 minutes. Every 1-3 seconds i would lose 1 minute of battery life. It was when it hit 140 Min left that the battery life % stabilized. And at 140 Min, it took longer than 1 minute before the battery went down to 139 Min, etc. Sooooo, if the battery is supposed to last 140 Min with no devices plugged in. I think the replacement battery works perfect (so far). If it's 200 Min with no devices plugged in, then there may be an issue with battery life. I think it may actually be 140min but then why would it tell me 200min? Not sure. Due to there being different versions of this UPS model, that makes it even more confusing to find the answer. But so far, after 140 Min, the battery seems very stable. ____________________________ WARNING, BE CAREFUL when changing the battery: First, in order to change the battery (for the model that i own), put the UPS on it's side. There's 1 screw on the bottom of the UPS. Unscrew it, slide over the plastic cover, remove the cover. NOW you have access to the battery. There's a pull tab attached to the battery to help you pull the battery out. BUT the battery is connected to two terminals, positive and negative (red and black)... (almost like a car battery), you will need to unplug it to remove the battery. So slide the battery out as far as you can, then detach the cables. The danger here is, the replacement battery has no plastic cover to protect one of the terminals. So both metal terminals are exposed. I'm not an electrical expert but i do know it's dangerous if you were to touch both the terminals with metal at the same time. I believe that's what you'd call a short circuit. That's VERY bad. What would happen if you short circuit the battery? Most likely some smoke, fire and a potential BOOM! So avoid that at all cost. The original battery has a plastic cover on the red terminal to help prevent that accident. The replacement battery does not include that. BUT DON'T FEAR, it's easy to replace the battery. BUT again, be careful, After i plugged in the red terminal to the new battery and then i tried to plug in the black connector next, a big spark flew. That was scary. Use plyers, grab onto the rubber piece of the connector and connect it that way. For safety. ALSO be careful when putting the replacement battery in. I almost pinched the red cable when sliding the new battery in with the cables connected. So go slow, make sure you clear the cables, so you don't pinch the cable. ____________________________ IN CONCLUSION: The $40 is worth the replacement battery considering this UPS would cost around $130 brand new. But i'm still not sure if the full battery life should be 140min or 200min (with nothing plugged in) If it's 140min then i 100% recommend this battery. It works perfect. (So far) If it's supposed to be 200min, you might be getting short changed. Either way, it's still a good purchase. It works, only cost $40 PLUS this is the only replacement option available.

It works. Packing was good. Delivery was good. My payment was good. All good. The instructions for replacing the battery for my model were accurate. What was lacking were suggestions on to deal with removing the clips on the old battery if they do not release easily. I asked AI and it suggested using needle noise plyers and a flat head screwdriver and cautioned me not to pull on the wires. It worked and I did no damage.

Works as expected. No issues with installing or charging the battery. I'm a little surprised my CyberPower UPS did not give any audible warning the original battery was no longer holding a charge and actually just simply shut down. Not good. But that's more of criticism of CyberPower. I have now labeled the date I replace the battery and just plan to get a new one in about 3 years. Rechargeable batteries do not last forever. Replacement battery arrive and install as expected and I'm satisfied with my purchase.

Perfect fit, came with 82% charge, bought to replace a dead battery worked since 2016!

100% Recomendado...

I bought this battery for a Cyberpower CP1000AVRLCD unit. I had the same battery in it since 2015. It finally started to not charge and would get scary hot. So hopefully this battery will solve everything. So far, installation took literally 2 minutes and it seems to be charging nicely. Mine arrived at 4% charge instead of being full which was a little odd, but it seems to be charging fine. Sounds like I won't get 7 years out of this battery like the original one, but for the price hopefully this will last at least a few years.

Great replacement, works as expected!

La compré para reemplazar la batería del modelo cp1000 y funcionó muy bien y es muy fácil de reemplazar

My power back up for my computer was squealing every time we had a power blip, and would not reset. Realized the battery was old so bought this one and its like new again for a great price. Very easy to replace!
