Review: Exactly what I was looking for! - I bought 1 of these and used it to replace the battery in my CyberPower unit. It was easy to do and now it works great once again. This saves a lot of money to just replace the batteries rather than buying a whole new unit. I used to use APC brand battery backup and AVR units, but then I realized they are pretty much a scam. With APC, you buy an expensive unit, it comes with the battery. Then 3 or 4 years down the road, the battery starts failing as you might expect. But with 2 different APC units I've had, I went on their site to buy a replacement battery, and it wasn't in stock. It appeared to be discontinued. Then I started looking up batteries for other APC units and realized that they seemingly only stocked batteries for the latest units. None of the ones for older units... you know, the ones where you would actually need a replacement. However, they offered a seemingly large discount on buying an entirely new battery backup unit, but only if you bought it off their site at their super-inflated regular price. With the discount on their regular price, it brought the price down to about what you expect off desertcart or best buy or whatever. In other words, the discount was worthless. So at the end of all this, I concluded that the APC units were a scam that you wouldn't discover until many years down the road. That was about 11 years ago when I came to that final conclusion. Since then, I've stuck with CyberPower because they keep the same models of backup units in service for a very long time. The unit I bought 10 years ago (the one that takes THIS battery) is still sold on desertcart for example. And getting genuine replacement batteries for them is easy and not a ripoff. In conclusion, APC lost me as a customer 10+ years ago, and I'm not going back. It was a no-brainer to switch to any unit that didn't pull these shenanigans. So I started using CyberPower units and haven't ever regretted it. Maybe APC has changed their philosophy since then? But I'm not going to look into that matter because... who cares... Review: Fit and perform like OEM because they are OEM - My cyberpower UPS (CP1500AVRLCD ser.# starting CPA) stopped working due to suspected battery failure (over 5 years old). I considered a generic battery, and I have used them on other UPS' in the past, but decided to spend the extra on a quality OEM replacement. Per instructions, I removed the old battery, installed the replacement. It fit perfectly, no fiddling with the batteries to stick together, the replacement had the same wiring harness as the original and the replacement fit perfectly. The UPS is functional again. Very happy. FWIW, I checked and one of the old batteries reads 13.4 volts sitting, but any load and and it drops to 0 volts. The other battery is useable, but likely has reduced capacity. So if your Cyberpower UPS is not working, it is likely to be old batteries. The OEM replacement are easy to use, and known quality. I expect another 5 years from these. The replacement is easy. Remove one screw, slide the front panel down to open the front. Unplug the red and black wires (They are polarized, so you can't hook up backwards). SLide the old battery pack out, slide the new one in. reconnect the wires. Replace the front panel, install the screw. Voila', functioning UPS. ## Features - The CyberPower RB1280X2A UPS Replacement Battery Cartridge restores life to CyberPower UPS systems that have weak or completely depleted internal batteries; It comes with two 12V/9Ah sealed lead-acid batteries - SEALED LEAD-ACID BATTERIES: Supplies high surge currents, provides robust power-to-weight ratios, and cost effective; MAINTENANCE-FREE BATTERY FLUID: Never requires replacement - USER-INSTALLABLE CARTRIDGE: Allows for quick and convenient installation; each cartridge is pre-assembled; The RB1280X2A comes in reusable packaging for delivering expired batteries to recycling centers - Compatible with these CyberPower models: CP1350AVRLCD (with serial numbers beginning with 'CPK'), CP1500AVRT, CP1500AVRLCD (with serial numbers beginning with 'CPT' or 'CPA') - 18-MONTH WARRANTY: Covers defects in materials and worksmanship in the product under normal use and conditions within eighteen months of the purchase date ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B009ACPBXK | | Amperage | 2 Amps | | Antenna Location | UPS Systems | | Battery Capacity | 9 Amp Hours | | Battery Cell Composition | Other Than Listed | | Battery Cell Type | Other Than Listed | | Best Sellers Rank | #128,779 in Health & Household ( See Top 100 in Health & Household ) #295 in 12V Batteries | | Brand | CyberPower | | Built-In Media | Battery,Installation Guide | | Compatible Phone Models | Universal/SmartPhones | | Customer Reviews | 4.5 out of 5 stars 1,145 Reviews | | EU Spare Part Availability Duration | 18 Months | | External Testing Certification | Não Aplicável | | Global Trade Identification Number | 00649532602049 | | Item Dimensions | 6 x 8 x 3 inches | | Item Height | 3 inches | | Item Type Name | SLA AGM Battery | | Item Weight | 12 Pounds | | Manufacturer | CyberPower Systems | | Model Name | CPS RB1280X2A Replacement Batteries | | Model Number | RB1280X2A | | Number of Batteries | 2 12V batteries required.

Some of the less expensive replacement batteries are not. I decided to spend more on these batteries since I experienced short life on some non-OEM computer batteries in the past. Well packed -- double boxed. The leads could be a tad bit longer. ## Frequently Bought Together - CyberPower RB1280X2A UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/9Ah - CyberPower CP1500PFCLCD PFC Sinewave UPS System, 1500VA/1000W, 12 Outlets, AVR, Mini Tower,Black - CyberPower RB1280X2B UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/8Ah --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/15795782-cyberpower-rb1280x2a-ups-replacement-battery-cartridge-maintenance-free-user-installable](https://www.desertcart.com.kw/products/15795782-cyberpower-rb1280x2a-ups-replacement-battery-cartridge-maintenance-free-user-installable) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-16*
