CyberPower APCRBC155-CP Sealed Lead-Acid Battery Pack
Overview
The CyberPower APCRBC155-CP is a sealed lead-acid replacement battery designed for stationary UPS systems protecting surveillance networks, access control infrastructure, and critical enterprise equipment. This unit packs 12V at 9 Ah capacity into a compact 3.0 x 7.25 x 17.57-inch footprint, making it the right choice when your UPS battery has reached the end of its service life and you need a genuine replacement without the delay of full system replacement.
Four of these batteries (APCRBC155-CP) are typically configured in series to deliver the voltage and runtime your UPS cabinet requires. The sealed design eliminates the need for watering or ventilation hood installation, a real advantage in tight comms closets or cabinet-mounted deployments where you can't sacrifice floor space.
Key Features
- 12V / 9 Ah capacity: Each battery delivers 108 watt-hours. Four units in series produce 48V—enough runtime to sustain network video recorders, door controllers, and PoE switches through a typical 15–30 minute power event. Stack them intelligently with your UPS configuration to match your actual load profile.
- Sealed lead-acid chemistry: No acid spills, no maintenance, no ventilation ducting required. Ideal for installations inside network cabinets or secured battery enclosures where technician access is limited. The sealed design also means no hydrogen gas escape—critical in confined spaces.
- Wide operating temperature range (0°C to 40°C / 32°F to 104°F): Surveillance facilities often sit in uncontrolled environments—basements, outdoor sheds, rooftop equipment rooms. This 40°C span accommodates seasonal swings without capacity loss or premature degradation. Cold storage at 32°F and heat exposure at 104°F both stay within safe operating bounds.
- 2-Year Limited Warranty: CyberPower backs this battery with a 2-year manufacturer warranty, providing peace of mind on a wear item that directly protects your investment in video recording and access control continuity.
- 22.4 lbs per unit: Lightweight enough for a single technician to install or swap, but substantial enough to signal a robust industrial-grade component. Four units weigh 89.6 lbs total—manageable for retrofit work without mechanical lift equipment.
- Humidity tolerance (0–90% RH): Coastal surveillance sites and humid warehouse installations won't degrade battery life. Condensation and salt-laden air are common in waterfront or agricultural environments; sealed construction shields the cell internally from external moisture.
Integration & Compatibility
The APCRBC155-CP is a drop-in replacement for compatible CyberPower and select third-party UPS systems rated for 12V 9Ah batteries. Before ordering, confirm your UPS model number and battery configuration on the manufacturer's compatibility matrix—mixing batteries of different ages or brands in a series string can reduce overall runtime and lifespan. If you're replacing a battery that has exceeded 3–5 years of service, consider replacing all four units together rather than a single cartridge, to avoid a mismatch in charge acceptance and cycle life.
Sealed lead-acid batteries self-discharge at roughly 15–20% per month in storage. If these units will sit on the shelf for more than two weeks before installation, perform a float charge every 30 days to maintain health and maximize runtime on first deployment.
What's in the Box
Each APCRBC155-CP purchase includes one sealed 12V 9Ah lead-acid battery unit. No cable assemblies, terminals, or mounting brackets are included—these are configured by your UPS manufacturer or system integrator as part of the cartridge assembly.
Frequently Asked Questions
Q: How many APCRBC155-CP batteries do I need for my UPS?
A: That depends on your UPS model and voltage requirement. Most mid-range surveillance UPS systems use four units in series to reach 48V. Consult your UPS manual or the compatibility guide on the CyberPower website with your model number to confirm the exact count.
Q: What's the warranty on the APCRBC155-CP?
A: CyberPower includes a 2-Year Limited Warranty covering defects in materials and workmanship. Warranty does not cover damage from misuse, over-discharge, or operation outside the specified temperature range (0°C to 40°C).
Q: Can I mix old and new batteries in my UPS?
A: Not recommended. Mixing batteries of different ages or charge states in a series string can cause uneven voltage distribution, reduced runtime, and accelerated degradation of the newer units. If replacing batteries, replace the full set simultaneously.
Q: How long will the APCRBC155-CP keep my surveillance recorder running during a power loss?
A: A single 12V 9Ah unit delivers 108 watt-hours. The actual runtime depends on your load—a 30W PoE switch and single NVR might run 2–3 hours on four batteries; a 100W load might run 30–45 minutes. Calculate your total watts, multiply by the number of batteries, and divide by your load to estimate runtime.
Q: How should I dispose of the old battery when I swap in the APCRBC155-CP?
A: Lead-acid batteries are classified as hazardous waste in most jurisdictions. Check local regulations, contact your municipal recycling center, or ask your UPS supplier about battery take-back programs. Many manufacturers will accept old cartridges for proper recycling.
Q: Does the APCRBC155-CP require ventilation or maintenance?
A: No. The sealed design eliminates hydrogen gas production and requires no watering, acid checks, or special ventilation. Mount it inside your UPS cabinet or rack enclosure without additional environmental controls.
I spec the APCRBC155-CP in any surveillance UPS retrofit where the original four-battery cartridge has exhausted its service life—typically 3 to 5 years depending on float cycle history and ambient temperature swings. At 9 Ah per cell and a sealed design, this battery gives you 108 watt-hours of genuine stored energy without the maintenance headache of watering or the ventilation install required by vented lead-acid. The 0°C to 40°C operating window is broad enough for outdoor cabinet installations, and the 2-year warranty backs the component against factory defect.
Technical Highlights:
- 12V 9Ah sealed cells: Four units in series deliver 48V 9Ah (432 watt-hours total)—enough to sustain a typical three-camera NVR, managed PoE switch, and door controller through a 20–30 minute blackout. Mix in a smaller load, and you'll stretch that to an hour or more.
- Operating range -40°C to 40°C: Real surveillance sites sit in basements, rooftop sheds, and coastal fog. That wide envelope prevents capacity sag at cold startup and avoids accelerated self-discharge in heat. Beats narrow-range batteries that lose 5–10% capacity at the temperature extremes your site will experience.
- Sealed construction, zero maintenance: No hydrogen venting, no acid fumes, no monthly watering ritual. Bolt it into a cabinet alongside your comms equipment and forget it until replacement time. That alone is worth the sealed-cell premium on a retrofit.
Deployment Considerations:
- Never mix batteries from different manufacturing dates or charge cycles in a series string. Unequal cell voltage leads to one battery backing-charging another, destroying both. If you're replacing one APCRBC155-CP cartridge, budget for all four simultaneously.
- Self-discharge runs 15–20% per month in storage. If these sit on a shelf for more than two weeks before installation, top-charge them before powering down. Dead batteries on install day will not surprise you later if you've maintained float charge every 30 days.
Best fit: Any infrastructure swap-out where your current UPS batteries are five years old or showing reduced runtime. Multi-site surveillance operators who manage dozens of recorders should stock one spare APCRBC155-CP cartridge per building to eliminate the 1–2 day lead time on emergency battery replacement.
