Compatible APC PowerShield Kit

This replacement battery kit is designed for APC UPS units that require a 12V 18A high-rate discharge SLA battery. It provides a direct, factory-fresh power source to restore backup runtime. The kit includes comprehensive installation instructions for straightforward user replacement. It suits IT administrators and home-office users maintaining existing APC power protection systems.

Single Battery Cartridge Design

The kit consists of one sealed lead-acid cartridge weighing 15 units, delivering 12 volts and 18 amps of capacity. It fits into the existing UPS chassis without requiring modifications to wiring or mounting hardware. Replacing the cartridge frees the UPS to resume full autonomous operation during mains failures. No additional components or tools beyond basic hand tools are needed for the swap.

Suits Direct APC CP50B48 Replacement

This product suits buyers who need a new 12V 18A battery to match the original CP50B48 specification exactly. It is not for users whose UPS requires a different voltage, amp-hour rating, or multi-battery string configuration. Buyers needing lithium chemistry, hot-swappable modules, or extended runtime bundles should look at other solutions.

Questions about this item

How long will the 12 V 18 A SLA battery keep my UPS running during an outage?

Runtime depends on the connected load; the 18 Ah rating gives a capacity baseline for calculating expected minutes.

Does the sealed lead-acid cell generate noticeable heat or fan noise during continuous float charging?

The battery itself is passive and silent; any warmth or noise comes from the UPS charger, not the cartridge.

Will this cartridge fit my APC UPS without extra cables or mounting hardware?

It is built as a direct CP50B48 compatible replacement and includes the factory connectors needed for installation.
