1500mAh Ni-MH alarm battery

This 7.2V 1500mAh Ni-MH rechargeable pack replaces the 300-03864-1 and LKP500-4B cells used in Honeywell LYNX PLUS and LYNX Touch security panels. It restores backup power so the system stays active during mains outages. The pack is supplied new and ready for installation.

Suits owners of listed LYNX panels

Installers or homeowners with an L3000, L5000, L5100, L5200 or L7000 control unit can use this as a direct replacement. It also fits the L3000GSMPK and K5109 models referenced by the manufacturer. Systems that require a different voltage, chemistry or form factor will not accept this pack.

7.2V 1500mAh Ni-MH specification

The decisive figure is the 7.2V 1500mAh nickel-metal-hydride rating, which delivers 10.80Wh of energy. Match this voltage and capacity exactly to the original battery label before ordering. A mismatched voltage or chemistry will prevent the panel from charging or holding a proper backup charge.

Questions about this item

When will the 1500mAh Ni-MH pack need replacement?

The 1500mAh Ni-MH pack typically lasts three to five years in alarm-panel backup duty; plan on swapping it once runtime drops below the panel's required backup window.

What limits runtime during a prolonged mains outage?

The 10.80Wh capacity is the hard ceiling — once the 7.2V pack discharges to the panel's low-voltage cutoff, backup ends until mains returns.

Does the battery generate noticeable heat or noise while the panel runs continuously?

Ni-MH chemistry stays cool and silent during float charge and standby; only a heavy discharge-charge cycle produces slight warmth, never audible noise.
