Restore your high-capacity 2U rack-mount Smart-UPS to factory runtime with this fully assembled, hot-swappable OEM battery sled.
Your 3000VA rack-mount Smart-UPS is the powerhouse of your server cabinet. When its internal batteries inevitably age out after 3 to 5 years, you are faced with a choice: risk your entire IT load on unverified aftermarket batteries, or restore your UPS to its exact factory specifications. The APC Genuine Replacement Battery Cartridge #43 (RBC43) is the official, Schneider Electric-certified power module designed specifically for APC's heavy-duty 2U systems. This is not a box of loose 12V blocks that your IT team has to manually tape and wire together. The RBC43 arrives as a fully assembled, heavy-duty metal sled complete with high-current wiring and fuses. Simply slide the old tray out and slide the new one in, restoring your mission-critical backup power without ever dropping the load to your connected servers.
Key Features & Benefits:
-
True OEM Certification: Guaranteed to meet or exceed original APC factory specifications. Deploying a genuine RBC43 ensures your UPS maintains its rigorous UL safety certification and keeps your $150,000 Equipment Protection Policy completely intact.
-
Zero-Downtime Hot-Swapping: Your servers cannot afford to go offline for a maintenance window. The RBC43 is designed to be safely swapped while your UPS continues to deliver perfectly clean, uninterrupted power to your rack.
-
Fully Assembled Metal Sled: Rebuilding aftermarket battery trays is dangerous, time-consuming, and voids warranties. The RBC43 arrives pre-wired inside its factory metal housing, meaning your technicians can complete the swap in minutes, not hours.
-
Intelligent Auto-Detection: Once the new sled is firmly seated and connected, your Smart-UPS will automatically detect the genuine cartridge, clear the flashing red battery alarm, and recalibrate your exact runtime availability.
-
Eco-Friendly Recycling: Every genuine APC replacement battery includes a prepaid return shipping label (in the US) and clear instructions for the safe, EPA-compliant recycling of your heavy, spent lead-acid tray.
