12V 12AH UPS Replacement Battery

This 12 volt 12 ampere-hour sealed lead acid battery uses AGM technology for maintenance-free operation. It serves as a direct OEM replacement for UPS and emergency backup power systems. The unit carries a two-year warranty on non-UPS applications and a three-year warranty on UPS devices. It ships new and ready to install.

Suits UPS and backup power systems

Buyers maintaining uninterruptible power supplies, emergency lighting, alarm panels or DC control systems will find the correct voltage and capacity here. The F2 terminal layout matches the specified UB12120 D5775 form factor. Users needing a different terminal type, higher capacity or lithium chemistry should look at other products.

F2 terminal and 151 mm length

The single specification that decides fit is the F2 terminal combined with the 151 millimetre length and 98 millimetre width. These dimensions and the terminal style must match the battery compartment and wiring harness of the host device. Verify both measurements before ordering.

Questions about this item

Does the 12 V 12 Ah AGM battery generate noticeable heat or noise during continuous UPS operation?

The sealed lead-acid AGM design runs silently and produces minimal heat under normal float-charge conditions in a UPS.

What existing hardware must I already have to install these F2-terminal batteries?

You need a UPS or device that accepts two 12 V 12 Ah blocks with F2 faston terminals and the 151 × 98 × 101 mm footprint.

Will the 151 mm length and 101 mm total height fit the battery compartment of my older RBC6-compatible UPS?

Yes, the dimensions match the standard UB12120 D5775 form factor used in legacy RBC6 UPS units.
