Question: What is maintenance like on an UPS?  Isn't the battery constantly being overcharged?  How often should you replace a battery in an UPS?
Document: I have switched from APC to CyberPower. I was constantly having APC units go bad or having to replace batteries in them. I have never had that problem with any of the CyberPower UPSs that i have bought. And i have bought about 30 of them. Their software that comes with the UPS for configuring it is also nice, but i have never really had to use it.
I found that APC Back-UPS would typically last 1 to 2 years with the original batteries and then up to 1 year per set of replacement batteries. This just didn't seem right. The UPS feature seldom needs to kick in, so it frustrates me to replace this technology so often. I was ready to try a different brand, so I tried CyberPower.Just 7 months in, this model failed to keep a light to medium load powered for a split second outage. I don't consider that to be acceptable.
inexpensive UPS for our servers. Runs smoothly. Easy to replace battery when it wears out. People like the displays. No problems so far.
It seems the batteries are good for 3 or 4 years at best before you need to replace them. This was a replacement and I really like it and all the features for powering up and down. I have it connect to a NAS File Server along with my MAC Pro, Printers, Displays and more. I really wanted the surge protection and the battery backup is mainly for the NAS File Server which know to power off when the UPS is active.
We bought several of these to replace several APC Back-UPS 1000 that were causing the PC to reboot whenever the UPS switched from power to battery and back. This was killing us as we're in a fairly old building and small power bumps happen frequently.These CyberPower UPSes work great. What I like best is the PowerPanel Business Edition software that allows me to monitor each unit on my network, and run diagnostic tests. Very easy to install and use.
Needed to replace my APC UPS due to the battery no longer being able to handle the load where during power drop the UPS would fail and the units attached would shut down. I was looking at APC again but came across Cyberpower and they seemed like nice product for the price. I've had this unit for over a week and so far I'm pleased. I really like the display read out that shows vital information such as backup time, electrical currents, and load.
This is my first UPS with battery backup. I have an Alienware computer with an i7 970 and a ATI 5870 graphics card, and a 24 inch monitor hooked up to the battery backup. I get an estimated 22 minutes of life before it shuts down. Works great. Love the display and I personally appreciate the screen auto off function after about 20 seconds. Definitely should be an option for those who want to see it constantly though.My first experience with a battery backup has been great. Well recommended.
I bought this device because I like having our network and computers protected from Lightning, surges and brown downs. This is an outstanding device for protection, and it is considerably less expensive than the competition (which I stopped using because of the heavy price. The consumer can also replace the battery at a small price, and avoid having to replace the entire unit.
Bought this to replace an APC Parachute similar sized model for my home office. The APC battery went in under 18 months, and the cost for replacement was not that much less thanbuying this new Cyber Power Unit. I especially like the automatic power down (logical shut down) of my server after an extended outage before the back up unit power is exhausted.
I use two large UPSes in my home office for my computers and network gear. I have had good experiences with other CyberPower units like these, so when it was time to replace my aging APC models, I chose these. They are more compact, yet offer plenty of power and battery back-up capacity for my setup. I also especially appreciate the line conditioning these units provide.
Answer: Hello, just to make it clear I purchased a CP 1350AVR LCD UPS (the picture shows a CP 1500AVR LCD) The model you select depends on the total load that you need. This is the second CP UPS that I've have. I had a CP 1200AVR (no LCD) for around 7 years. It worked great until the batteries needed to be replaced. The unit always stays plugged in and on even if the computers are turned off (I have my modem and router connected) and I have never had an issue with overcharging. I would not worry about overcharging. We don't get many long term power outages but we do get a fair number of quick on/off/on power surges which can cause problems if you are using the computer. This unit's AVR fixes those issues and protects your computer and the work that you were doing. It beeps and tells you that you lost A/C power and the time left on the backup batteries. It gives you time to save and close your work and shut down your PC normally. There is no maintenance on these UPS. CP recommends replacing the batteries between 3 to 6 years. That depends on how often they are used for backup and to what amount you drain them. I wait a few minutes and if the power does not come back on I would then shut things down and wait until the power was back on. As I said, I got seven years out of the original batteries. You know when to replace the batteries when things don't work as normal. At that point you can go to the software and do a "self test" and that will tell you - my PC just shut down! I would recommend that around six years you get new batteries, but again that depends on how many times you drain them down. Hope this helps.
