Review: Una batería de gran calidad, a punto estuve de gastar en un nuevo no break ya que no encontraba baterías y ya me había dado por vencido hasta que vi que comenzaron a vender originales... Vale la pena comprar la batería para dejar como nuevo tu no break Review: I bought this RB1280X2B replacement battery pack (2-batteries set by CyberPower ready-to-go) to replace a failed battery pack in my old CTS1400S (1400va) UPS. They came when promised, were delivered on-time and properly, were boxed properly and well-secured safe from any damage. They arrived fully charged. The existing battery pack was easy to extract (remove 2-screws from the bottom of the face plate, slide it down about 3/8" of an inch to release the tabs from the slots, and gently pull off) and the new pack was easy to slip in. It was about a 3-min project altogether. The hardest part was removing the power plug from the existing battery pack as it's a nice tight fit. After getting this setup I plugged int he unit and verified it was working, plugged in a very light load and simulated a power failure. I let it draw down to 80% capacity, then plugged it back into utility power to check for charging issues. It passed all tests and is now in service. The tech I spoke to at CyberPower years ago recommended as a rule-of-thumb no more than 3-battery rotations, the original plus two, but in any kind of production environment figure two rotations (original plus one replacement) then replace the UPS. This seems to hold true for us as after the first set of replacement batteries goes out, they charger circuitry is getting pretty beat up. All-in-all the CyberPower replacements have been a good value for us. I can't speak to "aftermarket" types, but it's worth noting the CyberPower-labeled battery pack we received was made by Leoth in China. ## Features - The CyberPower RB1280X2B UPS Replacement Battery Cartridge restores life to CyberPower UPS systems that have weak or completely depleted internal batteries; It comes with two 12V/8Ah 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 RB1280X2B comes in reusable packaging for delivering expired batteries to recycling centers - Compatible with the CyberPower model: CP1500PFCLCD - 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 | B00GOU93XA | | Amperage | 8 Amps | | Battery Cell Type | Sealed Lead Acid | | Brand | CyberPower | | Built-In Media | Battery Kit and Installation Guide | | Color | Black | | Customer Reviews | 4.6 4.6 out of 5 stars (733) | | Enclosure Material | Metal | | Form Factor | Rack | | Global Trade Identification Number | 00649532612116 | | Item Dimensions | 6.4 x 20.2 x 15.1 centimeters | | Item Type Name | SLA AGM Battery | | Item Weight | 10.98 Pounds | | Manufacturer | CyberPower Systems | | Mfr Part Number | RB1280X2B | | Model Number | RB1280X2B | | Specification Met | No | | UPC | 649532612116 | | Unit Count | 1 Count | | Voltage | 125 Volts | | Wattage | 96 watts | ## Product Details - **Battery cell composition:** Sealed Lead Acid - **Brand:** CyberPower - **Colour:** Black - **Material:** Metal - **Voltage:** 125 Volts ## Images ![CyberPower RB1280X2B UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/8Ah - Image 1](https://m.media-amazon.com/images/I/51hpiwppJ6L.jpg) ![CyberPower RB1280X2B UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/8Ah - Image 2](https://m.media-amazon.com/images/I/51k+ShLmNLL.jpg) ![CyberPower RB1280X2B UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/8Ah - Image 3](https://m.media-amazon.com/images/I/61UPtqxLusL.jpg) ![CyberPower RB1280X2B UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/8Ah - Image 4](https://m.media-amazon.com/images/I/61YE+ZEcMoL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: What, if any, differences are there between the rb1280x2a and rb1280x2b cartridges?** A: I talked to CyberPower tech support. The difference between the Rb1280x2A and RB1280X2B is the cable connector. The RB1280X2A has a male connector and a female connector on the exit. It actually replaces HR1234W that is in CP1500AVR. The RB1280X2B has two recessed female connectors. There is also a RB1280X2 which is just the loose batteries the are in the assemblies listed above. Hope this helps. **Q: Got an F03 code... will this new battery fix it or is my unit defective?** A: See https://www.cyberpowersystems.com/product/ups/cp1500pfclcd/. Scroll down and click Support tab for contact info and online form. Click Download tab to get the manual that explains lighted display: "FAULT: This icon (exclamation point inside triangle) appears if there is a problem with the UPS. Press the POWER button to turn off the UPS. F01: Battery Mode or AC/Utility Power Mode Overload fault (Turn on the UPS again.) F02: Battery Output Short fault (Turn on the UPS again.) F03: Charger Fault (Contact CyberPower Systems for support.) F04: Internal Fault (Contact CyberPower Systems for support.)" **Q: If I buy these, can I keep them stored to use them later on, or do they expire?** A: All lead-acid batteries have an expiration date that varies very little depending upon use. Typically there is less than a 6 month difference between no use, and full use, over the lifetime of such batteries. This is why car batteries are not filled with acid until sold. The acid eats away at the plates at a fairly constant rate. The disolved plate matter condenses at the bottom of the battery, when there is a reservoir. Once the reservoir is filled, the cells short out and become unusable, dead. **Q: The batteries in my cp1500pfclcd are 9ah batteries, the description shows 8ah batteries, can you confirm the capacity of these batteries?** A: You are absolutely correct. I have purchased 5 of the CP1500PFCLCD model UPS over the last 4-5 years, and are beginning to need battery replacements. The two batteries are joined in a unique way, and with a unique recessed connector which makes replacements very specific (unless you want to customize and re-wire the battery connections). It's rather disappointing from CyberPower to cheap out this way. Two 8 amp batteries gives 16 amps vs 18 amps with 9A batteries on the DC side of powering the UPS. Unless you know for sure, you are maxing out 12 .5 amps (1500 watts divided by 120v = 12.5 amps) you'll probably be fine. If you are thinking, my PC has a 1500 watt power supply, so I should get a 1500 watt UPS, it's doubtful your PC is pulling 1500 watts or 12.5 amps continuously. If so, your PC's power supply isn't going to last that long IMHO, and you should be looking at a higher rated UPS. Also, we do not know if the internal circuit design of the UPS is capable of outputting 1500 watts with 8A batteries, if so it would not last quite as long, a few seconds to a few minutes less depending on the load (what you have plugged into it). But yeah, you are right. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by F***. on 20 June 2023* Una batería de gran calidad, a punto estuve de gastar en un nuevo no break ya que no encontraba baterías y ya me había dado por vencido hasta que vi que comenzaron a vender originales...

Fit perfectly and took my CP1500PFCLCD back to like-new runtime of around 15 minutes at half load. I got about 4 years out of the original batteries. The old ones still worked but only lasted about 30-60 seconds so figured it was time to replace them. I’m happy with the price. Cyberpower seems to have reasonable replacement battery costs compared to other big manufacturers, which is great. Just be sure to check your original battery type before ordering. There are two types for the CP1500PFCLCD. If yours has a wire terminal hanging off the batteries, you need a different “A” type battery. This one is the “B” type with a socket between the batteries. Some of the other reviewers left negative review for this reason so be sure to check yours before you order. ## Frequently Bought Together - CyberPower RB1280X2B UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/8Ah - CyberPower CP1500PFCLCD PFC Sinewave UPS System, 1500VA/1000W, 12 Outlets, AVR, Mini Tower,Black - CyberPower RB1290X2 UPS Replacement Battery Cartridge, Maintenance-Free, User Installable, 12V/9Ah --- ## 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.vu/products/679348393-cyberpower-rb1280x2b-ups-replacement-battery-cartridge-maintenance-free-user-installable](https://www.desertcart.vu/products/679348393-cyberpower-rb1280x2b-ups-replacement-battery-cartridge-maintenance-free-user-installable) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
