12V 2.2Ah SLA replacement battery

This sealed lead-acid battery uses AGM technology to deliver 12 volts and 2.2 ampere-hours of capacity. It is built as a direct replacement for the FirstPower FP1223 and compatible DSC Alexor System BD2312 units. The maintenance-free design requires no watering or electrolyte checks during its service life.

Verify voltage terminal layout and physical fit

Before ordering, confirm that your device specifies a 12V 2.2Ah SLA battery and that the terminal arrangement matches the original FP1223 unit. Measure the available space in the battery compartment to ensure the replacement will seat correctly. Check that the existing charger is rated for sealed AGM chemistry.

AGM construction enables any-position mounting

The absorptive glass mat separator holds the electrolyte so the battery can operate safely on its side or upright without leakage. Gas recombination exceeds 90 percent during normal use, reducing internal pressure buildup. The sealed case meets IATA non-spillable classification for transport.

Questions about this item

Does the FP1223 arrive ready to install, or do I need to purchase cables or mounting hardware separately?

The battery is a sealed AGM unit with integrated terminals; no electrolyte, cables or brackets are supplied, so reuse the existing leads and hold-downs from the BD2312 or DSC Alexor System you are replacing.

The listing mentions FP1223 and BD2312 — which one matches my alarm panel?

FP1223 is the FirstPower model number; BD2312 is the DSC Alexor System part it replaces — both describe the same 12 V 2.2 Ah SLA battery, so order this item for either reference.

What does the 90 % gas-recombination figure mean for everyday backup use?

Over 90 % of gas generated during charge and discharge recombines internally, keeping the case sealed, eliminating water loss and allowing maintenance-free operation in any orientation for the 4–7 year design life.
