Others have commented that it is cheaper to get a couple of knockoffs and assemble them using the original tape and wire harness. With the shipping differences, I took perhaps a $40 hit by buying these. Amortized over their lifespan, I'm good with that. Having OEM CyperPower batteries rather than knockoffs may or may not be better but my

This was for our 8 year old Cyber Power electrical backup. The batteries are heavy and the fit is close. Also, you have to make sure the cables are out of the way of the cover. It took a couple of tries and got it in and hooked up. It was already fully charged so all was well

My old 1500AVR battery died almost 6 years to the day, wouldn't hold a charge even though it was reporting as 100% capacity avail and even would successfully pass self-tests. Power loss always resulted in an immediate cut. Always test manually by unplugging the UPS at the source.O.E. replacement arrived yesterday with a full charge.

My headline says it all ... it was delivered way before the time the order indicated. I had an e-mail notifying me of the delivery date. Very pleasant driver. A snap to install. Works perfectly even though it isn't the exact number of the original battery. The physical size of this replacement battery is slightly larger than the

Old alarm panel battery was not holding charge anymore, so the warning light kept coming on. Security alarm serviceman was going to come in and replace the battery for "just $60". This is the very same battery, which cost me $36 shipped. It took 30 seconds to change and the warning condition has gone away after a few

Product looked as advertised, and was delivered in a timely manner. Not everything you order at this time of Covid problems comes in a timely manner. What can you say about a battery? Only time will tell how long it lasts, however as soon as I removed the old battery and connected this one the alarm system started to function

Good value retrofit for original battery failure. I bought a Cyberpower CP1285AVR in 2010 the batteries failed 2021, so a good run. I searched for the replacement pack RB1280x2D, which is two batteries in series with a plastic spacer for the wires. Had trouble finding it and the price of the single batteries was decent. So you just peel

I'm not sure why Amazon wants me to rate "sheerness" or "warmth", because this is a battery. I gave 5 stars for easy to install. Now that I think about it, the case was very sheer but it was quite cold. Which is sort of what I expect from a sealed lead acid battery.The battery works just

Mostly just use this to power my cable modem, wifi router, and a mini low wattage PC for remote access. With this load I have just under 70 minutes. I don't get many power outages but they seem to always happen when I'm out, this prevents the loss of internet/wifi in my house.The installation is trivial, can be a bit tough to stuff the

UPDATE. It's 2020 June 22nd and this thing still works excellent. Last year during Hurricane Dorian I plugged this into my little generator to keep it charged, and plugged laptops, cellphones, lamps, you name it, into it. It's not really designed for power outages, but it serves well in a 1 week power outage as a charger for small

I bought these a while back for some new boxes I was building. I have owned at least 2-3 dozens of consumer UPS's (and a few retired ones from work) starting at the 90's after experiencing the first power outages that resulted in loss of data, and I've been using them ever since for each and every one of my computers (that I care

This machine does not work for aquarium and shall not be used with aquarium related products. I learned this the hard way. The purpose of UPS is that after the power outage, there is a battery back up so the machine can still running. However, for this machine, after the battery is used up, the UPS will turn off (which is normal).

This battery back-up has two sides: plugs with surge protection and battery back-up and the other side for surge protection only. Great price point for the power it provides for our PC, screen, 2.0 sound system etc. Has gone into use a few times with 110 power outages and provides ample time to shut down the PC correctly with back-up

I bought two of these to install into an aged APC BackUPS XS 1000. The original batteries gave a really good run time when they were new, but nothing lasts forever I guess.

This fit my 1500PFCLCD UPS perfectly and is a genuine CyberPower product. Check whether your unit has the "RB1280X2A" or the RB1280X2B battery in it before ordering a replacement.

I was looking for a UPS for the network equipment in my house (Router, Wi-Fi AP, Switch, NAS) and had to go with APC given its reputation for rock solid reliability.

My main issue is that it makes a very high pitched electrical noise that is way too bothersome for me to be able to use the product.
