APC by Schneider Electric CURK143-01-04 Battery Replacement Service Plan
Overview
The CURK143-01-04 is APC by Schneider Electric's Charge-ups 143 one-year service plan unit — a sealed lead acid (VRLA) battery replacement package rated at 120 V, intended to maintain runtime continuity in supported APC UPS systems. If your site depends on uninterrupted power for surveillance recorders, access control panels, or network infrastructure, replacing aging batteries on a defined service cycle is the most straightforward way to avoid unexpected runtime failures. The CURK143-01-04 includes one VRLA battery with a stated battery life rating of five years, giving you a predictable replacement horizon to work with.
Key Features
- 120 V Sealed Lead Acid (VRLA) Chemistry: valve-regulated lead acid construction means no free electrolyte, no routine watering, and no venting requirements — suitable for enclosed equipment rooms and server closets without additional ventilation provisions.
- Five-Year Battery Life Rating: a defined service life lets you schedule replacements proactively rather than reactively — important in surveillance and access control environments where a dead UPS during a power event is a critical failure.
- Operating Temperature 0–40 °C: covers standard indoor equipment room conditions, but note that operating toward the upper end of that range accelerates lead acid aging — battery rooms should stay below 25 °C for full rated service life.
- Operating Humidity 0–95% (non-condensing): wide humidity tolerance means the unit functions across most climate-controlled and semi-controlled indoor environments without derating.
- Operating Altitude up to 3,048 m (10,000 ft): no derating required for high-altitude installations such as mountain campus buildings or elevated equipment rooms.
- Compact Form Factor — 279 × 225 × 481 mm: fits within the physical envelope of compatible APC Charge-ups 143 chassis without requiring rack space reconfiguration.
Installation Notes
The CURK143-01-04 (often searched as CURK143 01 04) is a replacement battery assembly designed for use with the APC Charge-ups 143 platform. Verify compatibility with your specific UPS chassis model before ordering — APC battery cartridges are not universally interchangeable across product families. The unit ships with one battery; no additional batteries are included. Package dimensions are 293 × 253 × 495 mm at 25.2 kg — account for weight when planning delivery and installation logistics, particularly in overhead or elevated equipment cabinets.
Frequently Asked Questions
Q: What battery technology does the CURK143-01-04 use?
A: The CURK143-01-04 uses sealed lead acid (VRLA) technology — valve-regulated, maintenance-free, and safe for enclosed equipment rooms without special ventilation.
Q: What is the rated battery life for the CURK143-01-04?
A: The battery life is rated at five years under normal operating conditions. Actual service life depends on operating temperature — cooler environments extend life, while sustained high-temperature operation shortens it.
Q: What are the operating temperature limits for the CURK143-01-04?
A: Operating temperature range is 0–40 °C (32–104 °F). For longest battery service life, maintain the installation environment below 25 °C where possible.
Q: How many batteries are included with the CURK143-01-04?
A: One battery is included per unit.
Q: What is the voltage rating of the CURK143-01-04?
A: The battery is rated at 120 V, matching the APC Charge-ups 143 platform's power architecture.
The CURK143-01-04 is a VRLA battery replacement for the APC Charge-ups 143 platform — a maintenance item, not a performance upgrade, but one that matters operationally. A five-year rated service life gives facilities and security teams a clear replacement schedule, which is exactly what you want in a surveillance or access control environment where UPS failure during a power event means cameras go dark and doors may fail unpredictably.
Technical Highlights:
- VRLA Construction: sealed, valve-regulated design eliminates electrolyte maintenance and hydrogen venting concerns — you can install this in a locked IT closet or wall cabinet without additional ventilation infrastructure.
- 0–40 °C Operating Range: covers all standard climate-controlled indoor environments, though sustained temps above 25 °C will shorten the five-year rated life — a real factor in non-air-conditioned equipment rooms in warm climates.
- 25.2 kg Package Weight: this is a heavy battery assembly — plan for two-person installation and verify that your equipment rack or cabinet shelf is rated for the load before sliding it in.
Deployment Considerations:
- Verify exact chassis compatibility before ordering — APC battery cartridges are platform-specific and the Charge-ups 143 family does not accept batteries from other APC UPS lines interchangeably.
- At 25.2 kg shipping weight, coordinate delivery logistics for installations above ground floor; freight elevator access or a second technician is not optional on this one.
The CURK143-01-04 is the right call for planned battery maintenance cycles in facilities running APC Charge-ups 143 UPS units to back surveillance NVRs, access control hardware, or network switching — anywhere a reactive replacement approach is unacceptable.
