Replacement security alarm battery

This sealed lead-acid unit serves as a direct replacement for ADI ADEMCO 456-651 and compatible Enersys Cyclon models. It fits security panels, emergency lighting and telecommunications backup systems that require a 6V 5.0Ah pack with F2 terminals. The 1-pack format suits single-bay installations.

Upgrade from depleted or mismatched cells

The battery replaces legacy units such as Dual-Lite 12-706, 12-793, 0120706 and 0120793 as well as Hawker Cyclon 0809-0012 and X-Cell 0809-0010 references. The jump is worth it when the original pack no longer holds charge or when a starved-electrolyte design is specified for longer service life and rugged construction.

Capacity and headroom for backup duty

Rated at 5.0Ah, the monobloc delivers reliable runtime for alarm panels, UPS units, medical equipment and solar electronics. The patented starved-electrolyte system supports fast recharge, high discharge rates and low internal resistance. It is not suited for cyclic deep-discharge applications or installations that demand higher amp-hour reserves.

Questions about this item

Will the 5.48" length, 2.12" width and 3.02" height fit my ADI ADEMCO 456-651 alarm panel?

The battery measures 5.48" long, 2.12" wide and 3.02" high, matching the original ADI ADEMCO 456-651 dimensions for a direct fit.

How do I connect the F2 (.250) Fast-On terminals without damaging the spade connectors?

Push the .250 Fast-On terminals straight onto the F2 spades until they click; do not bend the tabs sideways or the connection will loosen over time.

When should I replace this 6V 5.0Ah sealed lead-acid battery in my security system?

Plan replacement every 3–5 years or when the panel shows a low-battery trouble code, as sealed lead-acid capacity drops with age.
