BATNI13 Daitem Panel Pre 2007 Replacement Battery 6V 1500mAh

Daitem Panel Pre 2007 — 6V Ni-MH Replacement Battery (BATNI13)

This is the BATNI13 replacement battery for the Daitem alarm control panel manufactured before 2007. It runs at 6V Ni-MH with 1500mAh (9Wh) capacity, supplying backup power to the panel during mains failure. If your panel is showing a low battery fault or failing to hold backup power, this cell is the direct replacement.

• Pre-2007 Daitem panel compatibility: These legacy panels use a 6V Ni-MH cell with a specific connector and charge management circuit. The BATNI13 matches the voltage rail and physical envelope — 71.10 x 50.20 x 14.50mm — required by the panel's battery bay.
• Bench tested on actual hardware: We ran this cell through charge acceptance and float stabilisation cycles. The panel's BMS accepted the cell cleanly and transitioned to float without triggering a fault condition after a full conditioning period.
• Post-install charge conditioning: Do not run a zone or siren test immediately after fitting this cell. Allow 24–48 hours on the panel's float charge before any diagnostic test. Running a test too early can cause the panel to log a low battery event even when the cell is functioning correctly.

Alarm panel losing programming during a power outage after fitting the new battery

The Daitem pre-2007 panel relies on the backup cell to hold volatile memory during mains loss. A freshly fitted Ni-MH cell has not yet completed its first full charge cycle and may carry insufficient charge to sustain panel memory under load. If the mains drops before the cell has fully conditioned — typically within the first 48 hours — the panel can lose zone programming, user codes, or event logs. Fit the new battery, restore mains power, and allow a full 48-hour charge period before disconnecting mains for any test or planned outage.

Panel still showing low battery fault 30 minutes after fitting the BATNI13

This is a charge state issue, not a cell fault. The panel's BMS reads cell voltage before reporting battery status — a new Ni-MH cell ships at a storage charge level, often below the panel's low-battery threshold voltage. The panel will continue to show a low battery indication until the cell charges sufficiently, which typically takes 24–48 hours on float. If the fault clears within that window, the cell and panel are operating correctly. If the fault persists beyond 48 hours, check the panel's charge voltage output at the battery terminals — it should read between 6.8V and 7.2V with the cell connected.
