Who it fits

Key specs explained for AJC

Voltage: 12V

This value indicates the electrical pressure the battery provides to your UPS system. You need a 12V unit to match the internal requirements of most standard uninterruptible power supplies. If the voltage does not match exactly, the UPS will not function correctly or may be damaged. Always check your original battery label to confirm this number before purchasing a replacement.

Capacity: 9Ah

The amp-hour rating shows how much energy the battery stores. A 9Ah capacity determines how long your computer and monitors will stay running during a power outage. Higher numbers mean longer backup time. This spec helps you compare if this replacement matches the runtime of your original unit or if you need a larger battery for extended protection.

Waveform: Pure Sine Wave

This describes the shape of the electrical current the battery supports within the UPS inverter. Pure sine wave output is clean and stable, making it safe for sensitive electronics like servers and gaming PCs. It prevents humming or overheating in power supplies. You should verify your UPS model supports this waveform to ensure compatibility and optimal device protection.

Dimensions: 5.94 x 2.56 x 3.7 inches

These physical measurements tell you if the battery will fit inside your UPS chassis. You must compare these numbers to the space available in your unit. A mismatch in length, width, or height can prevent the battery from seating properly or connecting to the terminals. Accurate sizing ensures a secure fit and reliable electrical contact within the device.

Design and Build Details

According to the listing, this AJC battery is a sealed lead-acid unit built for the CyberPower PFC Sinewave CP1500PFCLCD UPS. The casing is a standard rectangular block. It measures 5.94 inches in length, 2.56 inches in width, and 3.7 inches in height. These dimensions are critical because they must fit the specific battery compartment inside your UPS. If the size does not match the original slot, you cannot install it. The weight is listed at 5.8 pounds. This mass is typical for a 12V 9Ah battery and suggests a robust internal plate structure. It is not a lightweight travel unit. It is designed for stationary use in a home or office. The pure sine wave attribute is a key design feature. It means the battery supports inverters that output a smooth, clean power curve. This protects sensitive electronics from damage. You do not need to worry about complex wiring or external controls. The unit is a direct replacement. There are no displays, buttons, or apps to manage. The design is purely functional. It sits inside the UPS and provides backup power when the grid fails. The sealed construction means you do not need to add water or check acid levels. It is maintenance-free. This simplicity is a benefit for most users. You install it, and it works. The build focuses on reliability and compatibility rather than fancy features. The compact footprint allows it to fit in tight spaces within the UPS chassis. This is a practical design for a backup power source.

Setup And Daily Use Guide

Installation requires matching the physical dimensions and electrical output of your existing unit. The listing specifies a length of 5.94 inches, a width of 2.56 inches, and a height of 3.7 inches. You must verify that your UPS bay accommodates these exact measurements. The unit weighs 5.8 pounds, which is standard for this capacity class. Handling it with care is necessary to avoid damaging the sealed lead-acid cells during removal and insertion.

This battery is designed specifically for the CyberPower PFC Sinewave CP1500PFCLCD model. It provides a 12-volt output with a 9Ah capacity. The pure sine wave specification is critical for your connected equipment. Unlike modified sine wave batteries, this unit delivers a smooth, consistent power signal. This waveform mimics the clean power from your utility grid. It ensures that sensitive electronics, such as computers and medical devices, operate without interference or overheating.

In daily use, the battery supports your UPS during power outages. The 9Ah rating determines how long your devices stay online. Heavier loads will drain the battery faster, while lighter loads extend runtime. The sealed design means you do not need to add water or perform maintenance. It is a maintenance-free solution for keeping your systems running. The pure sine wave output protects your hardware from potential damage caused by distorted power waves. This feature makes it suitable for a wide range of sensitive electronics that require clean power. The unit is ready to use once installed correctly in the designated UPS slot.

Before You Buy This Battery

You need to confirm your UPS model matches the CyberPower PFC Sinewave CP1500PFCLCD exactly. This AJC unit is a direct replacement, not a universal fit for all 12V slots. Check your existing battery label for the 12V 9Ah rating. The pure sine wave specification is critical for sensitive electronics. If your original unit was modified or is a different brand, this may not work. You should also verify the physical dimensions. The listing states it measures 5.94 by 2.56 by 3.7 inches. Ensure your UPS compartment has enough space. Proper disposal of your old lead-acid battery is required. Recycling centers handle this safely. This option suits users who want a spec-matched replacement without changing their UPS hardware. It fits alongside other pure sine wave batteries by offering exact compatibility. You avoid the risk of mismatched voltage or waveform issues. Focus on verifying the model number first. Then check the dimensions. Finally, confirm the 9Ah capacity matches your power needs.

Check before you buy

• Verify your UPS is a CyberPower PFC Sinewave CP1500PFCLCD model.
• Confirm your old battery is 12V and 9Ah capacity.
• Check that your UPS bay fits 5.94 by 2.56 by 3.7 inches.
• Ensure your devices require pure sine wave output.
