Direct UB12150F2 replacement

This two-pack supplies 12 V 12 Ah sealed lead-acid batteries built to replace the UB12150F2 model in UPS units, emergency lighting, alarm panels and similar backup systems. Advanced AGM construction makes them maintenance free and suitable for indoor installations.

Capacity difference decides fit

Each unit delivers 12 Ah compared with the 15 Ah of the original UB12150F2, so runtime will be proportionally shorter. Verify that the reduced capacity still meets the load and autonomy requirements of your specific device before purchasing.

Sealed AGM design runs cool and silent

The absorbed glass mat electrolyte eliminates gassing during normal float charging, so no ventilation or active cooling is required. Typical self-discharge is low, giving an expected service life of four to seven years in standby use.

Dimensions match original footprint

Physical size is 151 mm long, 98 mm wide and 101 mm total height with terminals, matching the UB12150F2 envelope. Each battery weighs approximately 4.20 kg, allowing a straight mechanical swap without bracket modifications.

Questions about this item

What does the 12Ah rating mean for UPS runtime?

The 12Ah capacity provides slightly less stored energy than the original 15Ah unit, so backup time will be reduced proportionally under the same load.

What connector type does the F2 terminal use?

The F2 terminal is a standard faston tab that accepts push-on spade connectors common in UPS and alarm systems.

Will the 151mm length fit my existing battery tray?

Each battery measures 151mm long, 98mm wide and 101mm total height, so verify your tray allows at least those clearances.
