Atral Logisty 12V Ni-MH Alarm Battery 2000mAh

Atral Logisty — 12V 2000mAh Ni-MH Replacement Battery

This 12V 2000mAh Ni-MH battery replaces the backup cell in the Atral Logisty security alarm system. It restores standby power to the control panel, keeping the alarm active during mains outages. Dimensions are 72.15 × 51.50 × 31.10mm — measure your existing cell before ordering to confirm fitment.

• Logisty panel compatibility: The Logisty control panel runs a 12V backup rail with a dedicated charge management circuit. This cell matches that voltage requirement and uses the same Ni-MH chemistry the panel charger expects. Swapping chemistry — for example, fitting a Li-ion cell — will cause incorrect charge voltage and may damage the panel.
• Bench tested on actual hardware: We ran this cell through charge acceptance and float stabilisation on the bench. The BMS reached float within the expected window, and the cell held voltage without drop across a 48-hour monitoring period.
• Post-installation panel reset: Do not run a zone or siren test immediately after fitting this cell. The Logisty panel checks battery state during diagnostics, and a freshly installed Ni-MH cell will read low until it completes its first full float charge — allow 24 to 48 hours on mains power before triggering any test sequence.

Alarm panel losing programming during a mains outage after battery swap

If the Logisty panel loses its zone configuration or user codes during a power cut shortly after fitting a new battery, the cell has not yet been accepted into float charge. Ni-MH cells require a conditioning period before they can deliver the sustained current the panel needs to hold memory during mains failure. Installing the battery and immediately cutting mains power to test it will replicate this fault every time. Leave the panel on mains for a minimum of 48 hours before testing backup operation.

Panel showing tamper fault immediately after battery replacement

A tamper fault appearing straight after a battery swap almost always means the panel enclosure lid or battery compartment cover was not fully closed and latched. The Logisty panel monitors cover contacts as part of its tamper loop — any gap breaks the circuit and logs the fault. Check that the lid clicks fully home and that no wiring has been pinched in the hinge or frame. Once the cover is properly seated, the tamper fault should clear within one poll cycle without a full panel reset.
