Frequently Asked Questions
Which APC UPS models is the RBC18 compatible with?
A: The RBC18 cartridge is compatible with the following APC models: PS250, PS250I, PS450, PS450I, SC250RM1U, SC250RMI1U, SC450R1X542, SC450RM1U, and SC450RMI1U. To confirm compatibility, locate the model number on the label on the back or bottom of your UPS unit before ordering.
How do I install the RBC18 battery cartridge?
A: Installation is straightforward and typically requires no tools. The cartridge slides into the battery bay of your APC UPS and connects using the existing wiring harness. Because the RBC18 is hot-swap compatible, you can complete the replacement while the UPS remains plugged in and actively protecting your equipment.
Will using a third-party battery void my APC UPS warranty?
A: In most cases, no. Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your warranty solely because you used a third-party replacement part. They would need to demonstrate that the third-party part directly caused the failure in question. Using our RBC18 replacement cartridge is a legal and often more affordable alternative to purchasing directly from APC.
Is the battery charged when it arrives?
A: Sealed lead-acid batteries like the RBC18 ship with a partial charge and will condition fully once connected to your UPS. For the best performance, allow your UPS to complete a full charge cycle before depending on it for backup power. Most APC units will display a ready or charged indicator once the battery is fully conditioned.
