Your rack UPS is warning you the battery bank is degrading, and the last thing you need is a surprise shutdown mid-transaction or during a hospital ward backup. You need the exact cartridge your unit was designed around.
The APC RBC27 is a genuine 48V enclosed lead-acid battery cartridge built on Panasonic cells. It ships with a metallic tray so it seats cleanly into the UPS bay — one cable, all connectors, installation guide, and recycling guide in the box.
Important: the SU48R3XLBP requires two RBC27 cartridges to complete the battery bank. If that's your unit, you'll need a pair. We can confirm your model number before you order so you don't end up half-protected.
Operating range 0–40 °C, storage −5 to 45 °C. 2-year APC warranty.
