Replacement battery for APC RBC47

The BatteryJack 12 V 3.3 Ah sealed lead-acid unit is a direct 100 % OEM replacement for APC RBC47 and PS-1230 cartridges. It fits a wide range of Back-UPS ES models including BE325, BE350, BE350G and BE350U as well as CyberPower CPS325SL and similar UPS units. Maintenance-free AGM construction makes it suitable for emergency lighting, fire alarm panels and security systems.

Thermals noise and power draw

Sealed AGM chemistry produces no audible noise and requires no ventilation beyond normal cabinet airflow. Self-discharge is low enough to support a 4 to 7 year service life in standby applications. The battery delivers its rated capacity at 12 V without active cooling or maintenance cycles.

Capacity and terminal spacing

Rated at 3.3 Ah with a terminal centre distance of 1.6 inches, the cell matches the electrical and mechanical interface of the original RBC47 cartridge. Overall dimensions are 5.28 by 2.64 by 2.4 inches, ensuring it seats correctly in the listed UPS housings.

Questions about this item

How do I install the 12V 3.3AH SLA battery in my APC RBC47 UPS, and what is the common mistake?

Disconnect the UPS from mains power before opening the battery door; the step most people miss is reconnecting the red lead to the positive terminal and the black lead to the negative terminal in the correct order.

What maintenance or replacement will this AGM battery need later?

The sealed AGM design is maintenance-free for its 4-7 year expected life; after that period the entire 12V 3.3AH unit must be replaced as individual cells cannot be serviced.

What limit appears first when this battery runs under sustained UPS load?

The 3.3AH capacity determines runtime; once the stored charge is depleted the voltage drops and the UPS shuts down, so capacity is the first limit reached during extended discharge.
