The APC RBC2 is a maintenance-free, sealed lead-acid replacement battery for compatible APC Back-UPS models, including BE500R, BE550MC, BK500, SC420, and SU420NET, making it suitable for owners replacing the battery in a listed UPS.

Recommended For

  • Owners of a compatible APC Back-UPS whose battery has reached end of life and who want to restore the UPS’s original backup performance.
  • Home-office users with a compatible Back-UPS who need a replacement battery for brief interruptions while they save work or shut down a computer and monitor.
  • Home-network or small-office users with a compatible APC UPS who want to restore temporary battery backup for a modem, network connection, or other data-sensitive equipment.
  • APC Back-UPS owners who have confirmed RBC2 is the replacement listed for their exact UPS model and prefer replacing the battery cartridge rather than the entire working UPS.
