ExpertPower EXP1290, 2 Pack 12V 9AH SLA AGM Rechargeable 12V Battery Backup

So far so good. Just installed (took less than 5 mins) and 4 screws later my UPS is back up and running showing a full charge. No more error messages on my CyberPower 1500. Direct replacement, shipped quickly and came charged at 95% when powered up. Can't speak to any longevity since I just installed it but my last battery set lasted for about 5 years so we'll see. At this price point if I get 12-18 mos out of it, it would be worth it. Because its lead acid and is not constantly charging and discharging, it should hold up for a while.

This is a great battery pack for anyone needing a dependable 12V replacement or backup power solution. I found the ExpertPower EXP1290 batteries easy to install, and they arrived ready to use. The 9Ah capacity provides solid performance, and the AGM design makes them convenient and maintenance-free. Getting two batteries in the pack is also a good value, especially for UPS that call for thiss, alarm systems, emergency lighting, or other backup power applications. Overall, these are reliable, well-built batteries that do exactly what they're supposed to do.

My Cyber Power UPS CP1500va, md# CP1500AVRLCD, went belly up, no power back up when the shore power went down. System showed the batteries at 100% but due to their age they did not have the amps capable to back up my system. After research I purchased these replacement batteries. I received the new batteries and they are physically identical, an exact replacement. 12v-9.0ah x 2. I spent 10 minutes and replaced the old with new and the system is working well at this time. Only time will tell the longevity of the new batteries. The original batteries lasted 5 years. Thank you!!

Get about a year out of them. Buts that all you get from ones twice the price. I have four in a UPS.

I have a CyberPower 1500VAC Battery Backup that began throwing the E02 error. This error is indicative of the current batteries not holding the appropriate voltage. Upon investigating, these batteries appeared to be direct replacement and so I went for it. These arrived exactly as advertized and were, in fact, exact replacements for the ones I removed from my CyberPower. I tested the voltage of each prior to installation and they were both showing about 14v. Knowing the voltage was good, I quickly got them installed and powered up the device. The batteries arrived with an approximate state of charge around 90%. I have been running these for just over a week without any issues. This was a very simple and straightforward fix with a quality replacement at a fair price. I have chosen to rate this product 5 stars. It has met my expectations for the price and I would completely recommend. Although I haven't had them for very long, I have monitoried them every day and they are holding the charge as expected. Due to my immediate need for the replacement batteries, I didn't spend much time reading previous reviews, but these are definitely worth reviewing. They were exactly what I was looking for and working exactly as advertised. Criteria for Stars: 1 - Total rip off, doesn't perform basic advertised functions or not product advertised. I would likely RETURN and would NEVER recommend. 2 - Not worth the money. Performs some of the basic advertised functions, but likely not all, and ultimately was deemed as not providing enough value for the money spent. I would not buy again, and would likely not recommend unless the buyer had a very specific use case. 3 - It performs the basic functions as advertised, and has some usefulness at the price point, but doesn't work for all of the reasons I purchased. I would likely not buy again, and would only recommend if buyer understood usefulness limitations. 4 - It performs most all of the features I purchased it for, but has limitations. I would likely buy again and would recommend. 5 - Completely as advertised and likely exceeded expectations. Is if high quality and well shipped. I would totally buy again and recommend.

Bought a set of these to replace the OEM batteries in my CyberPower 1500 UPS. The OEM batteries had lasted a little over 4 years (Dec 2016 - Feb 2021) before starting to throw alarms on the unit. I bought my first set of these in March of '21, and they lasted until June '26. Thus I will happily be ordering another pair. $40-$45 for >5 years of performance is a fantastic deal in my experience.

Bought this for a Hyper Toy Company, HPR350 24V Electric Dirt Bike child's electric dirt bike and it works great. Like a new bike. I'm not a hundred percent sure but I think it will also work on a Razor Dirt Rocket MX350 - Blue, up to 14 mph, 24V Electric-Powered Dirt Bike for Child. I'm about ninety percent sure it will work on that model, after researching the battery. I'm thankful we got the right batteries we needed. I'm very happy with this product.

I bought the ExpertPower EXP1290 2-pack 12V 9AH batteries to use as replacement batteries for my UPS, and they worked well for that. The fit was good for my setup, and installation was straightforward. Once installed, the UPS recognized the batteries and was back up and running like it should. That is exactly what I wanted instead of replacing the whole UPS. The quality feels solid so far, and the batteries seem like a good option for backup power, UPS units, ride-on toys, emergency lights, or other small 12V battery uses as long as the size and specs match what you need. For value for money, I think the 2-pack is a good deal. Replacement UPS batteries can get expensive, so being able to swap these in and keep the unit working makes sense. I can’t speak to long-term durability yet, but so far they are doing the job with no complaints. Would I buy them again? Yes. Good replacement batteries for my UPS.

Great battery, good price.

Las baterías llegaron en el tiempo estimado, bien empacadas y funcionan bien.

It's been in my UPS for about a year without trouble. So far, so good. I've read some people complaining about the connectors being too small, but i didn't have any problems making my connections (of course, you have to make sure you don't attach your cable connectors upside-down).

No son de la capacidad original, pero funcionan perfecto, duran probablemente 30-40% menos, pero en mi caso eso significa tener prendidos un par de dispositivos no críticos (TV) por un par de horas si se llega a ir la electricidad por mucho tiempo... por ejemplo terminar de ver una película, cosas así.

They're batteries. I plugged them in. They work. They're black with square corners. What more do you want me to say?
