Direct UPS Battery Replacement

The APC RBC63 is a sealed lead-acid cartridge designed to restore runtime to compatible S-type power conditioners with battery backup. It delivers a 48 V DC output and arrives ready for installation without fluid handling.

Maintenance-Free Sealed Construction

Suspended electrolyte technology eliminates the need for watering or orientation checks during its service life. At 25.50 lb the unit is a single-piece swap that fits the existing battery bay without extra brackets or cables.

Runtime Window and Chemistry Limits

Expected battery life spans 26297.44 to 43829.06 hours depending on load and temperature conditions. Lead-acid chemistry means capacity will gradually decline and the cartridge is not suited for applications requiring lithium-ion energy density or rapid recharge cycles.
