12V 7.0Ah UPS Replacement Battery

This sealed AGM battery delivers 12 volts and 7.0Ah capacity as a direct OEM replacement for the APC RBC2 cartridge. It fits a wide range of Back-UPS and Smart-UPS models including the BE500R, BK500, and SU420NET series. The maintenance-free design offers an expected service life of four to seven years under normal float conditions.

Verify Battery Count Before Ordering

Open the UPS battery compartment and count the internal cells before purchasing. Units containing a single battery require one RBC2 replacement, while units with two batteries need an RBC1 pack instead. Confirming the configuration prevents ordering the wrong kit and ensures proper runtime restoration.

Suits Home and Small-Office UPS Owners

This pack is built for users replacing a depleted cell in compatible APC units up to the 550VA class. Buyers needing higher-capacity packs for larger rack-mount UPS systems or those seeking lithium-based chemistry should look at alternative product lines.

Questions about this item

Does the BatteryJack RBC2 come with cables or mounting hardware, or must I buy them separately?

The battery ships as a single 12 V 7.0 Ah AGM unit; cables and mounting brackets are not included and must be sourced separately if your UPS does not reuse the original hardware.

How do I decide between the RBC2 and RBC1 for my APC unit?

Open the battery door and count the cells: one 12 V block means you need the RBC2, while two blocks require the RBC1 instead.

What runtime can I expect from the 7.0 Ah capacity in a Back-UPS 500?

Runtime varies with load, but the 7.0 Ah rating matches the original specification for supported models such as the Back-UPS 500, delivering the manufacturer’s rated backup time when the battery is fresh.
