APC Charge-ups #57 1-YR SP-04 - CURK57-01-04

APC by Schneider Electric CURK57-01-04 Replacement Battery Cartridge

Overview

The CURK57-01-04 is APC by Schneider Electric's Charge-UPS #57 replacement battery — a single lead-acid cartridge designed to restore runtime capacity in compatible APC UPS units when the original battery has reached end of service life. If your surveillance infrastructure, network closet, or facility equipment depends on APC battery backup, keeping a verified replacement on hand prevents unplanned downtime when the original pack degrades. The CURK57-01-04 (often searched as CURK57 01 04) ships as a single unit in black, matching the original factory configuration.

Key Features

• Lead-Acid Battery Chemistry: Sealed lead-acid construction delivers the reliable, maintenance-free operation that field technicians expect in always-on environments — no electrolyte checks, no venting concerns in enclosed equipment rooms.
• 3-Year Battery Life Rating: APC rates this cartridge for a 3-year service interval, giving facilities managers a concrete replacement schedule rather than guessing when runtime starts to degrade. Plan battery swaps proactively around this cycle to avoid emergency replacements.
• Single-Battery Configuration: Ships with one battery unit, sized for UPS models that use the #57 cartridge slot. Verify your UPS model accepts the #57 cartridge before ordering — using the correct cartridge number is the single most common compatibility error in battery replacement workflows.
• 0–40°C Operating Temperature Range: Rated for operation from 0°C to 40°C (32°F to 104°F), covering standard equipment room, server closet, and indoor security head-end environments. Installations in unconditioned spaces near the upper boundary will shorten effective battery life — keep ambient temp below 25°C for maximum longevity.
• -15°C to 45°C Storage Temperature Range: The extended storage range (-15°C to 45°C) means you can warehouse spare cartridges in non-climate-controlled storerooms without degrading the cells before deployment — useful for bulk spare inventory at facilities with multiple UPS units.
• 0–95% Operating Relative Humidity (Non-Condensing): Rated across the full 0–95% RH operating band, so humidity in typical equipment rooms and security head-end enclosures won't be a concern. Avoid condensing conditions — the non-condensing caveat matters in environments with rapid temperature swings.
• Compact Form Factor — 165 × 70 × 419 mm: At 165mm wide, 70mm tall, and 419mm deep, this cartridge fits the physical slot geometry of compatible APC Charge-UPS systems. Confirm slot clearance before ordering if your rack or enclosure is tightly populated.
• 41.33 kg CO₂e Carbon Footprint: APC publishes lifecycle carbon data for this SKU at 41.33 kg CO₂e — relevant for organizations tracking Scope 3 emissions in their infrastructure procurement.

Integration & Compatibility

The CURK57-01-04 is designated for APC Charge-UPS systems that specify the #57 battery cartridge. Cross-reference your UPS model number against APC's battery replacement guide before purchasing — APC uses cartridge numbers (#57, #116, #140, etc.) as the canonical compatibility identifier. Installing the wrong cartridge number in a UPS chassis is not supported and may prevent the unit from operating correctly. No tools beyond a standard screwdriver are typically required for cartridge swap on most APC UPS chassis designs. The 1-YR SP-04 designation in the product name refers to the service plan tier associated with this cartridge SKU.

Frequently Asked Questions

Q: What UPS models is the CURK57-01-04 compatible with?

A: The CURK57-01-04 is designed for APC Charge-UPS systems that use the #57 battery cartridge. Cross-reference your specific UPS model number against APC's replacement battery selector to confirm compatibility before ordering. The cartridge number (#57) is the primary compatibility identifier.

Q: What is the expected battery life of the CURK57-01-04?

A: APC rates this cartridge for a 3-year battery life under normal operating conditions. Actual longevity depends on ambient temperature — operating consistently near the 40°C upper limit will reduce effective service life. For maximum life, keep the UPS in a space at or below 25°C.

Q: What are the operating temperature limits for the CURK57-01-04?

A: The operating temperature range is 0°C to 40°C (32°F to 104°F). Storage temperature extends from -15°C to 45°C, so spare cartridges can be warehoused in non-climate-controlled spaces without damage to the cells.

Q: How many batteries are included with the CURK57-01-04?

A: One (1) lead-acid battery cartridge is included per unit. If your UPS requires multiple cartridges, order the quantity needed to match your chassis configuration.

Q: Can the CURK57-01-04 be stored long-term before deployment?

A: Yes. The storage temperature range of -15°C to 45°C and storage humidity range of 0–95% support long-term warehousing in typical storeroom conditions, provided condensation is avoided. Follow APC's guidelines for periodic charge maintenance if storing for extended periods.

Karl Wilson

The CURK57-01-04 is a straightforward but operationally critical component — a factory-replacement lead-acid cartridge for APC Charge-UPS systems using the #57 slot. In surveillance and physical security head-ends, UPS battery failure is one of the most common causes of unplanned recorder or network downtime, and the 3-year rated service life on this cartridge gives you a concrete maintenance schedule to work with rather than reactive replacement after a power event exposes a degraded battery.

Technical Highlights:

• 3-Year Service Life: A defined 3-year replacement cycle lets you build battery swaps into annual maintenance contracts — far more manageable than chasing degraded runtime on a case-by-case basis across multiple UPS units in a facility.
• 0–40°C Operating Range: Covers virtually every conditioned indoor equipment room, but note that sustained high-end temperatures compress effective cycle life on lead-acid chemistry. If your head-end room regularly hits 35°C+, plan to inspect capacity annually rather than waiting the full 3-year interval.
• Sealed Lead-Acid Chemistry: No maintenance, no electrolyte top-off, no venting requirements — appropriate for enclosed AV/security equipment racks where gel or AGM alternatives may not be specified by the chassis OEM.

Deployment Considerations:

• Confirm the #57 cartridge number against your UPS chassis model before ordering — APC's cartridge numbering system is the authoritative compatibility reference, and the wrong cartridge physically may not seat or charge correctly in a mismatched chassis.
• Storage humidity is rated to 95% but condensation is the watch-out: rapid temperature swings in a storeroom (e.g., loading dock adjacent to cold storage) can cause condensation on battery terminals even within the rated RH envelope.

This cartridge is the right call for facilities teams running scheduled maintenance programs on APC Charge-UPS deployments in security operations centers, NVR head-ends, and access control infrastructure — anywhere a proactive swap prevents the battery from becoming the weakest link in a hardened physical security system.
