Review: Works as-expected, a bit pricey - 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.
Review: Great replacement, works as well as OEM. - I have a CyberPower CP1500PFCLCD, which is one of the models that takes two batteries. I was a little concerned because I had read conflicting things about battery compatibility. As others here have said, these work just fine, you just have to remove some tape and separate them. Getting the new batteries plugged in was way easier than I was expecting as well. The battery backup is back up and running, and for a fraction of the cost of a whole new unit.

## 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.

### ⭐⭐⭐⭐⭐ Required expense if you own a UPS
*by S***. on June 3, 2023*

I have two UPSs currently in operation. One 8 years old and one four years old, both running off of their original batteries. The older one finally started complaining about its battery not holding a charge, so I needed to get a new one. This UPS was running my cable modem and firewall, so critical to my network. The other UPS was on my main system and accessory equipment. I decided to give the 4-year old a load test and it failed. Ok, guess I'm getting two new batteries now. CyberPower's battery design is two 12V batteries in series instead of in parallel. Without a lot of work to reconfigure two generic batteries, I just went ahead and bought the appropriate CyberPower units. The two batteries were well packaged and protected from shipping damage. There were no outer boxes, just the original boxes with a UPS sticker slapped on them. No biggie. Installation was quite simple. A single screw to remove in order to slide the front panel off and disconnect the cabling. The older UPS has typical 1/4" spade connectors so it was a little work to disconnect the old battery and connect the new one. The 4-year old has a nonstandard connector making generic replacements more difficult, but making reconnection with approved components a breeze. I'm glad I replaced them when I did because last week the power went out without notice for a couple hours and I could shut my computer, my NAS and firewall down correctly with time to spare. Well worth the investment!
