What this battery replaces

The PowerStar HR1234W is a 12 V 9 Ah sealed lead-acid battery built with AGM technology for maintenance-free operation. It serves as a direct OEM replacement for UPS units, emergency lighting, alarm panels and similar float-application equipment.

Compatibility checks before ordering

Verify that your device requires a 12 V 9 Ah block and that the terminal style matches the F2 (T1/T2) faston tabs supplied. Confirm the available space accommodates the 5.94 by 2.56 by 3.66 inch footprint and that the application is a float or standby role rather than deep-cycle use.

Build and daily implications

The spill-proof, valve-regulated design allows mounting in any orientation without leakage risk. Low-pressure venting and high-recovery capability support a 4–7 year expected life in float service, while the maintenance-free construction means no watering or periodic checks are required.

Questions about this item

What comes with the PowerStar HR1234W and what else do I need?

The battery is shipped ready to install with F2 terminals; no cables or mounting hardware are included, so reuse the leads from the unit you are replacing.

How do I pick the right version of the HR1234W for my UPS?

Match the 12 V rating, 9 Ah capacity and the F2 terminal type shown on your existing battery label; the case measures 5.94 by 2.56 by 3.66 inches, so confirm those dimensions fit your chassis.

What does the 12 V 9 Ah rating mean once the battery is in my UPS?

It indicates a nominal 12-volt output and a 9-ampere-hour capacity, giving a baseline runtime that will vary with the actual load your UPS draws during an outage.
