What this battery is and who it fits

The PowerStar 12V 3.5AH SLA battery uses advanced AGM technology for maintenance-free operation. It is a direct 100% OEM replacement for the PE12V3AF1, PS-1230, UB1234 and WP3-12 models. The unit is designed for UPS backup, emergency lighting, fire alarm panels and security systems.

Check your existing setup before ordering

Verify that your device requires a 12 volt battery with a 3.5 ampere-hour rating and F1/F2 terminal spacing of 1.6 inches. Confirm the physical envelope of 5.28 by 2.64 by 2.4 inches fits the battery compartment. Match the replacement against the listed UPS cartridges such as RBC35, RBC47 and the APC BE350 series.

Suits users needing a drop-in SLA cell.

This battery suits owners of the compatible UPS, alarm and telecom units who need a sealed lead-acid cell with a four-to-seven-year expected life. It is not for buyers who need a different voltage, capacity or terminal layout, nor for applications that require lithium or nickel-based chemistries.

Questions about this item

What comes in the box with this 12V 3.5AH SLA battery and do I need to buy cables or connectors separately?

The battery ships as a single sealed unit with F1/F2 style terminals; no cables, harnesses or mounting hardware are included so you must reuse or purchase the correct leads for your UPS or device.

The title lists 3.5AH but the description says 3.3AH — which capacity should I choose for my APC BE350?

Both ratings refer to the same physical cell; the 3.3AH figure is the 20-hour discharge rating while 3.5AH is the nominal label — either value will power the BE350 because the battery matches the required dimensions and terminal spacing.

What does the 1.6-inch terminal spacing mean when I install this battery in my Cyber Power CPS325SL?

The 1.6-inch centre-to-centre distance matches the original UB1234 and PS-1230 packs so the battery drops straight into the CPS325SL tray and the existing connector plugs on without adapters.
