  4. Which replacement should you choose?

The UPLUS LP12-9.0 is the best CyberPower CP1500PFCLCD battery replacement for most buyers who want a 12V 9Ah AGM battery with stated compatibility. For a preassembled two-battery pack, the UPC RB1290X2-UPC is a more specific fit, but only when the UPS serial number begins with CXX.

The CP1500PFCLCD needs two 12V batteries. Check your unit's full model and serial number, then compare the replacement's quantity, terminal type and dimensions with the batteries already installed.

If you're comparing standard batteries beyond this UPS, see our guide to best replacement UPS batteries in 12V. For a similar CyberPower unit, our CP1500AVRLCD3 replacement battery guide covers that model separately.

Which CyberPower CP1500PFCLCD battery replacements stand out?

The UPLUS LP12-9.0 is the clearest fit among single batteries because it names the CP1500PFCLCD and publishes terminal and size details. The UPC pack offers a more direct cartridge replacement, with a strict serial-number condition.

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

The best CyberPower CP1500PFCLCD batteries

These picks include single replacement batteries, two-battery packs and two CyberPower UPS models for reference. Sort out the required quantity first: a CP1500PFCLCD uses two 12V batteries, so a single-battery option may mean buying two.

ExpertPower EXP1290: Best for a two-battery replacement

ExpertPower EXP1290, CyberPower CP1500PFCLCD replacement batteries
9.7/10Our score
  • Two 12V 9Ah SLA AGM batteries
  • F2 terminals
  • 5.94 x 2.56 x 3.70 in dimensions; 3.94 in total height

The two-battery pack matches the 12V 9Ah format and F2 terminals, with dimensions to compare against the UPS compartment before ordering.

See it on Amazon

Pros

  • Two batteries included
  • F2 terminals
  • Published dimensions

Cons

  • Compatibility with this exact UPS model is not specified

ExpertPower's EXP1290 comes as two 12V 9Ah SLA AGM batteries, making the pack quantity convenient for a UPS that needs two batteries. It has F2 terminals, and its stated dimensions are 5.94 x 2.56 x 3.70 in, with a total height of 3.94 in.

The supplied facts describe broad use in UPS systems, but they don't name the CP1500PFCLCD. Compare the terminal position and compartment size in your UPS before choosing this pair.

This set is a practical option if you want two batteries in one pack and your existing batteries match the listed format. It does not include model-specific confirmation for the CP1500PFCLCD, so verify compatibility against your unit.

CyberPower CP1500PFCLCD PFC Sinewave UPS Battery Backup: Best for checking the original UPS

CyberPower CP1500PFCLCD PFC Sinewave UPS Battery Backup, CyberPower CP1500PFCLCD replacement batteries
9.7/10Our score
  • 1500VA/1000W PFC sine wave UPS
  • Two 12V batteries required
  • Color LCD and automatic voltage regulation

This is the UPS itself, useful as a reference when confirming the exact model and battery arrangement before buying replacements.

See it on Amazon

Pros

  • Exact model name for identification
  • Specifies two 12V batteries
  • Color LCD shows battery and power conditions

Cons

  • Not a replacement battery

The CyberPower CP1500PFCLCD listing here is the UPS itself, not a replacement battery. It helps confirm that this model uses two 12V batteries and provides an exact model reference when checking the label on your unit.

The UPS is rated at 1500VA/1000W and has a color LCD that displays battery and power conditions. Automatic voltage regulation corrects minor power fluctuations without switching to battery power.

Use this reference if you are comparing your unit's model name or checking the original system's stated battery quantity. You still need a separate replacement battery pack or pair, and the exact serial number can matter for cartridge-style replacements.

UPLUS LP12-9.0 12V 9Ah Rechargeable AGM Battery: Best for stated CP1500PFCLCD compatibility

UPLUS LP12-9.0 12V 9Ah Rechargeable AGM Battery, CyberPower CP1500PFCLCD replacement batteries
9.6/10Our score
  • 12V 9Ah sealed lead-acid battery
  • F2 terminal with F1 adapters included
  • Stated compatible with CP1500PFCLCD

UPLUS names the CP1500PFCLCD as a compatible model and gives dimensions and terminal details to check against your battery compartment.

See it on Amazon

Pros

  • Names CP1500PFCLCD compatibility
  • F1 adapters included
  • Published size

Cons

  • Single battery; confirm the quantity your UPS needs

UPLUS names the CP1500PFCLCD among its compatible CyberPower models. The LP12-9.0 is a 12V 9Ah rechargeable AGM battery with F2 terminals and included F1 adapters.

Its dimensions are 5.95 x 2.56 x 3.68 in. Compare those measurements with the battery compartment, and remember that the CP1500PFCLCD uses two batteries.

This option is sold as one battery, so confirm how many you need.

Choose it when you want a battery that explicitly names your UPS model and offers details you can check before buying. For nearby models, compatibility may differ, so use the full model label rather than assuming one CyberPower battery fits every tower UPS.

CyberPower EC850LCD Ecologic UPS Battery Backup: Best for comparing another CyberPower UPS

CyberPower EC850LCD Ecologic UPS Battery Backup, CyberPower CP1500PFCLCD replacement batteries
9.5/10Our score
  • 850VA/510W UPS
  • 12 outlets
  • LCD and ECO mode

The EC850LCD is a different CyberPower UPS, so its battery details should not be treated as confirmation of CP1500PFCLCD battery fit.

See it on Amazon

Pros

  • Useful model reference within the brand
  • LCD shows battery and power conditions
  • ECO outlets can turn off peripherals

Cons

  • Not a CP1500PFCLCD replacement battery

The CyberPower EC850LCD is another UPS, not a replacement battery for the CP1500PFCLCD. Its model name and battery backup features can help distinguish it from the CP1500PFCLCD when checking labels, but its specifications do not guarantee battery compatibility with the larger model.

This EC850LCD has 12 outlets, an LCD panel and ECO mode outlets that can shut off connected peripherals when a computer is off or asleep. CyberPower states a three-year warranty that includes the battery.

Keep this item in view only if you are also comparing UPS systems. For a battery replacement, use a battery or pack that matches the CP1500PFCLCD's requirements and verified serial fit.

Mighty Max Battery ml9-12: Best for a single F2 battery

Mighty Max Battery ml9-12, CyberPower CP1500PFCLCD replacement batteries
9.4/10Our score
  • 12V 9Ah rechargeable SLA AGM
  • F2 terminal
  • 5.94 x 2.56 x 4.02 in dimensions

This single 12V 9Ah battery has an F2 terminal. Compare its 4.02 in height with the compartment and confirm whether you need one or two.

See it on Amazon

Pros

  • F2 terminal
  • Rechargeable SLA AGM
  • Published dimensions

Cons

  • Only one battery included

Mighty Max's ML9-12 is a single 12V 9Ah rechargeable SLA AGM battery with an F2 terminal. Its dimensions are 5.94 x 2.56 x 4.02 in, making height an important check against the CP1500PFCLCD compartment.

Because the UPS uses two 12V batteries, one unit alone is not a full replacement set. Confirm whether you need two matching batteries, then verify dimensions and terminal fit before ordering.

This option makes sense when you want a single F2 battery and can source the second one separately. The product details do not specifically name the CP1500PFCLCD, so check compatibility carefully.

RB1290X2-UPC Battery Pack for CyberPower UPS System: Best for matching serial CXX

RB1290X2-UPC Battery Pack for CyberPower UPS System, CyberPower CP1500PFCLCD replacement batteries
8.6/10Our score
  • Two 12V sealed lead-acid batteries
  • Direct replacement for RB1290X2
  • CP1500PFCLCD compatibility limited to serials beginning CXX

The assembled pack is a model-specific option only for CP1500PFCLCD units whose serial numbers begin with CXX. Check the serial before choosing it.

See it on Amazon

Pros

  • Names CP1500PFCLCD compatibility with a serial condition
  • Two batteries included
  • Two-year warranty stated

Cons

  • Not identified as compatible with every CP1500PFCLCD serial number

The UPC RB1290X2-UPC is a two-battery replacement pack for select CyberPower systems. For the CP1500PFCLCD, its compatibility is limited to units with serial numbers beginning CXX.

That condition makes checking the serial number essential. Find the UPS label and confirm the first three characters before buying; a similar model name does not override the stated serial restriction.

The pack includes two 12V 9Ah batteries and states a two-year warranty. Choose it when your CP1500PFCLCD serial matches the condition and you want a cartridge-style pack rather than two individual batteries.

SafeAMP 12V 9.5Ah UPS Battery for CyberPower: Best for an RB1290X2 two-pack

SafeAMP 12V 9.5Ah UPS Battery for CyberPower, CyberPower CP1500PFCLCD replacement batteries
8.3/10Our score
  • Two 12V 9Ah sealed lead-acid batteries
  • Compatible replacement for RB1290X2
  • Model compatibility requires verification

SafeAMP describes a two-battery replacement for the RB1290X2 and names select CyberPower models. Confirm your exact UPS model and serial fit before ordering.

See it on Amazon

Pros

  • Two batteries included
  • RB1290X2 compatibility stated
  • User-replaceable design

Cons

  • Compatibility with CP1500PFCLCD is not specified

SafeAMP describes this as a two-battery replacement for the RB1290X2 and names several CyberPower models. The CP1500PFCLCD is not among the models named in its compatibility details, so don't assume it fits based on the shared brand or battery format.

The two included batteries are described as 12V 9Ah sealed lead-acid units. SafeAMP calls the design user-replaceable and gives a six-month manufacturer warranty.

Consider it only after confirming with the seller that your exact CP1500PFCLCD model and serial are supported. For a nearby CyberPower model, use our CP1500AVRLCD3 battery replacement guide to keep the model-specific checks separate.

How do you choose a battery for the CP1500PFCLCD?

Choose by exact model and serial fit first, then confirm battery count, voltage, terminals and dimensions. A generic 12V 9Ah label is not enough to establish that a battery or pack fits your UPS.

Does the replacement include both batteries?

The CP1500PFCLCD requires two 12V batteries. ExpertPower and the UPC RB1290X2-UPC are two-battery options, while UPLUS and Mighty Max are listed as single batteries.

Check the pack quantity before placing an order. If buying two separate batteries, they should match in voltage, capacity, terminal type and condition.

Which terminals and dimensions should you check?

The ExpertPower, UPLUS and Mighty Max options specify F2 terminals. UPLUS also includes F1 adapters, but adapter availability does not replace checking the terminal setup inside your UPS.

Compare the full battery dimensions with the compartment, including total height when applicable. The Mighty Max measures 4.02 in high, while ExpertPower gives a 3.94 in total height.

When does the UPC pack fit?

The UPC RB1290X2-UPC names the CP1500PFCLCD as compatible only for serial numbers beginning with CXX. Read the complete UPS label before ordering, and do not treat compatibility with another CyberPower model as proof of fit.

The SafeAMP option names select CyberPower models, but the CP1500PFCLCD is not among those named. Confirm exact compatibility before considering it for this unit.

Which replacement should you choose?

Pick the UPLUS LP12-9.0 if you want a single 12V 9Ah battery that explicitly names the CP1500PFCLCD and gives terminal and dimension details. Choose the UPC RB1290X2-UPC if your unit's serial begins with CXX and you want a two-battery pack.

For a single F2 battery without model-specific confirmation, compare the ExpertPower and Mighty Max dimensions and buy the correct quantity. If you're comparing APC replacements too, see our APC RBC17 battery guide and APC BX1500M replacement battery guide.

Frequently asked questions

How many batteries does the CyberPower CP1500PFCLCD use?

The CP1500PFCLCD requires two 12V batteries. Before buying, check whether the replacement option is a two-battery set or a single battery, and compare terminal type and dimensions with the batteries in your UPS.

Is every RB1290X2 pack compatible with the CP1500PFCLCD?

No. The UPC RB1290X2-UPC pack specifies CP1500PFCLCD compatibility only for units with serial numbers beginning CXX.

Other options name select CyberPower models or the RB1290X2 cartridge, so verify your exact model and serial before ordering.

Can I use a 12V 9Ah battery in this UPS?

A 12V 9Ah format appears in the replacement options here, but capacity alone does not confirm fit. Check the battery quantity, terminals, dimensions and your UPS serial number against the replacement's stated compatibility.

What should I check before replacing the battery?

Confirm the full UPS model, serial number, number of batteries, terminal type and compartment dimensions. The CP1500PFCLCD takes two 12V batteries, while some options in this guide are sold as one battery and others as a two-battery pack.
