The CyberPower RB1280X2A is the strongest starting point for a CP1500AVRLCD3 replacement because CyberPower identifies the CP1500AVRLCD with a CPA serial prefix as compatible. Verify your exact model, serial prefix and battery connections before ordering, since the compatibility note does not name the “3” suffix separately.

A replacement can come as a ready-to-install cartridge or as a pair of individual batteries. The cartridge bundles the batteries into an assembly; loose pairs require you to confirm that the dimensions and terminals match the ones in your UPS.

Which CyberPower CP1500AVRLCD3 replacement battery fits best?

The RB1280X2A is the most directly supported choice in this group because its stated compatibility includes CP1500AVRLCD units with serial numbers beginning CPA. The remaining options may be useful when their battery setup and connections match your UPS, but confirm before buying.

We compared the stated compatibility, battery count, capacity, dimensions, terminals and warranty details. Our score weighs specs, features and buyer feedback against what you’re shopping for.

CyberPower RB1290 UPS Replacement Battery Cartridge: Best for a pre-assembled cartridge

9.7/10Our score

• One 12V/9Ah sealed lead-acid battery
• User-installable pre-assembled cartridge
• Reusable battery recycling packaging
• 18-month warranty

This pre-assembled cartridge is convenient to install, but its stated compatible models do not include the CP1500AVRLCD3. Confirm compatibility with CyberPower before choosing it for that UPS.

See it on Amazon

Pros

• Pre-assembled cartridge
• Reusable packaging for battery recycling
• 18-month warranty

Cons

• Stated compatible models do not include CP1500AVRLCD3

The RB1290 is a pre-assembled, user-installable cartridge with one 12V/9Ah sealed lead-acid battery. Its stated compatible models are CP1000AVRLCD, CP1000PFCLCD and CP1000PFCLCDTAA, so the CP1500AVRLCD3 is not among the named models.

CyberPower includes reusable packaging for delivering an expired battery to a recycling center and provides an 18-month warranty for defects under normal use and conditions. Those details make the cartridge convenient for a compatible CP1000 owner, but they do not guarantee fit in a CP1500AVRLCD3.

Before considering it for your UPS, confirm compatibility with CyberPower using the complete model and serial number. Don’t rely on the shared “AVRLCD” portion of two model names as a fit check.

CyberPower RB1280X2A UPS Replacement Battery Cartridge: Best for a matching CyberPower cartridge

9.6/10Our score

• Two 12V/9Ah sealed lead-acid batteries
• Pre-assembled user-installable cartridge
• Compatible with CP1500AVRLCD units with CPA serial prefix
• 18-month warranty

CyberPower names the CP1500AVRLCD with a CPA serial prefix as compatible. Check the complete model and serial details on your UPS to confirm the CP1500AVRLCD3 is covered.

See it on Amazon

Pros

• Explicit CP1500AVRLCD compatibility by serial prefix
• Two-battery cartridge arrives pre-assembled
• 18-month warranty

Cons

• Compatibility requires checking the serial prefix

The RB1280X2A contains two 12V/9Ah sealed lead-acid batteries in a pre-assembled cartridge. CyberPower names CP1500AVRLCD units with serial numbers beginning CPA among its compatible models.

That is the clearest compatibility match among these picks. Because the model in this guide includes a “3” suffix, check the serial prefix and confirm that CyberPower’s compatibility guidance covers your exact unit before ordering.

The cartridge is user-installable and comes with reusable packaging for recycling expired batteries. CyberPower provides an 18-month warranty for defects in materials and workmanship under normal use and conditions.

Mighty Max Battery 12V 9Ah SLA Battery: Best for a 9Ah battery pair

9.4/10Our score

• Two 12V/9Ah sealed lead-acid batteries
• 5.94 x 2.56 x 4.02 in each
• F2 terminals
• One-year warranty

This two-battery set is described as a replacement for the CyberPower CP1500AVRLCD. Compare its dimensions and F2 terminals with the batteries and connections in your CP1500AVRLCD3 before ordering.

See it on Amazon

Pros

• 9Ah capacity per battery
• Dimensions and terminal type are specified
• One-year warranty

Cons

• No wire harness or mounting accessories included

The Mighty Max pair provides two 12V/9Ah sealed lead-acid batteries and is described as a replacement for the CyberPower CP1500AVRLCD. Each battery measures 5.94 x 2.56 x 4.02 in and has an F2 terminal.

Mighty Max includes the batteries only, with no wire harness or mounting accessories. Check whether your CP1500AVRLCD3 uses the same terminal type and whether these dimensions fit its battery compartment.

The batteries are rechargeable and have a one-year manufacturer warranty. This option can suit a buyer replacing individual batteries who has verified that the battery arrangement, fit and connectors match.

4

Mighty Max Battery 12V 7.2AH Replacement Battery: Best for a 7.2Ah pair

9.0/10Our score

• Two 12V/7.2Ah sealed lead-acid batteries
• 5.90 x 2.50 x 3.90 in each
• F1 terminals
• One-year warranty

This pair has a lower stated capacity than the 9Ah options and uses F1 terminals. Check the UPS requirements and existing battery connectors before choosing it.

See it on Amazon

Pros

• Battery dimensions are specified
• Rechargeable sealed lead-acid batteries
• One-year warranty

Cons

• 7.2Ah capacity
• No wire harness or mounting accessories included

This Mighty Max set includes two 12V/7.2Ah sealed lead-acid batteries. Each measures 5.90 x 2.50 x 3.90 in and uses an F1 terminal.

Its 7.2Ah capacity differs from the 9Ah options above, so check your UPS requirements before considering it. The F1 connection also differs from the F2 terminals on the Mighty Max 9Ah pair and the Vici set.

Mighty Max says the batteries can be mounted in any position and provides a one-year manufacturer warranty. The set includes the batteries, without a wire harness or mounting accessories.

5

Vici 12V 9Ah SLA Battery Replacement: Best for an F2-terminal alternative

8.8/10Our score

• Two 12V/9Ah lead-acid batteries
• 5.95 x 2.56 x 3.7 in each
• F2 terminals
• Limited warranty

Vici offers another two-battery 9Ah option with F2 terminals and dimensions close to the Mighty Max pair. Verify the UPS fit, connection layout and warranty terms.

See it on Amazon

Pros

• 9Ah capacity per battery
• F2 terminals
• Dimensions are specified

Cons

• Compatibility with CP1500AVRLCD3 is not specified

The Vici pair contains two 12V/9Ah lead-acid batteries with F2 terminals. Each battery measures 2.56 x 5.95 x 3.7 in, making the dimensions close to those of the Mighty Max 9Ah pair.

Vici identifies these batteries as a replacement for the CyberPower CP1500AVRLCD, but does not specify compatibility with the CP1500AVRLCD3. Compare the exact size, terminal type and connection arrangement with your UPS before choosing this pair.

The set comes with a limited warranty. Check its terms before buying, particularly if you’re comparing it with the one-year Mighty Max warranty or the 18-month CyberPower cartridge warranty.

How do cartridge and loose replacement batteries differ?

A cartridge comes as an assembled battery unit, while loose replacement batteries are individual units that need to match the UPS compartment and connections. For a CP1500AVRLCD3, the RB1280X2A offers the clearest model-family match, subject to checking the serial prefix and exact suffix.

The two CyberPower cartridges here have different stated compatibility. The RB1280X2A names CP1500AVRLCD units with a CPA prefix; the RB1290 names CP1000 models instead.

Loose-battery sets make the terminal and dimension check especially important. The two 9Ah pairs from Mighty Max and Vici use F2 terminals, while the 7.2Ah Mighty Max set uses F1 terminals.

Match those details to the original batteries and the UPS instructions.

What should you match before ordering a replacement?

Match the full model, serial prefix, battery count, voltage, capacity, dimensions and terminals to your specific UPS. If any of those details differ, confirm the correct replacement with CyberPower before buying.

Start with the label on the UPS and the labels on the existing batteries. Record the voltage and capacity, then measure the batteries and note the connector type and orientation.

If you’re still comparing UPS battery options, our best APC BX1500M replacement battery guide covers a different APC model. For another CyberPower unit, see the CP1500PFCLCD battery picks, or compare options for the APC RBC17 cartridge.

Which CP1500AVRLCD3 replacement should you choose?

Choose the RB1280X2A first if your serial prefix and exact CP1500AVRLCD3 model are confirmed compatible by CyberPower. Pick an individual battery pair only when its battery count, capacity, dimensions and terminals match your UPS.

Frequently asked questions

Which battery fits a CyberPower CP1500AVRLCD3?

CyberPower names the RB1280X2A for CP1500AVRLCD units with serial numbers beginning CPA. Check the full model and serial number on your UPS, then confirm that the cartridge applies to your CP1500AVRLCD3 before ordering.

For loose batteries, also compare the required capacity, size and terminal connections.

Does the CP1500AVRLCD3 use one battery or two?

The CP1500AVRLCD3 battery setup should be confirmed using the UPS label or CyberPower’s guidance for your exact unit. The RB1280X2A contains two 12V/9Ah batteries, while the RB1290 contains one 12V/9Ah battery and names other compatible models.

Do not choose based on the CP1500 name alone.

Can I replace the cartridge with loose SLA batteries?

A loose-battery pair can be an option if its voltage, capacity, dimensions and terminals match the UPS requirements and original connections. The Mighty Max and Vici options here are two-battery sets, but their F1 or F2 terminals differ.

Check the original battery labels and connection layout first.

What should I check before ordering a UPS battery?

Match the complete UPS model, serial prefix, battery count, voltage, capacity, dimensions and terminal type. A similar model name does not confirm that a cartridge or battery pair fits your unit.
