Alula RE029 Connect+ Control Panel Replacement Battery 6V 2500mAh

Alula Connect+ Control Panel — 6V Ni-MH Replacement Battery (RE029)

This is a 6V 2500mAh Ni-MH replacement battery for the Alula Connect+ Control Panel, RE524X, RE508X, and RE6100P. It sits inside the panel and takes over when mains power drops, keeping the alarm active and notifications running during an outage. Part number RE029 matches the OEM cell these panels ship with.

• Connect+ panel family compatibility: The RE524X, RE508X, and RE6100P all use the same 6V backup rail and the same physical housing — the panel BMS expects this specific cell voltage and connector orientation across the entire line.
• Bench tested on actual hardware: We cycled this cell through full discharge and recharge on the Connect+ platform. The BMS accepted the new cell without fault flags after completing its float charge cycle. No tamper or low-battery codes appeared once the panel finished conditioning.
• Post-install charge window: Do not run a zone or siren diagnostic test in the first 24–48 hours after fitting this battery. The panel charges the new cell slowly from float — triggering a test before charge completes can cause the panel to report low battery mid-test, which is a false reading, not a fault.

Why the Connect+ panel reports low battery hours after a new cell is fitted

The Connect+ uses a float-charge circuit that trickle-feeds the Ni-MH cell rather than fast-charging it. A freshly installed cell starts below the panel's low-battery threshold voltage, so the alert fires almost immediately. This is normal — the panel is reporting actual cell voltage, not a fault with the battery. The low-battery flag should clear on its own after 24–48 hours on mains power once the cell reaches full float charge.

Alarm loses programming during a power outage after battery replacement

If the panel drops its zone programming when mains power fails, the backup battery had not yet been accepted by the BMS at the time of the outage. A new Ni-MH cell needs at least 48 hours on float charge before it can sustain the panel's memory and communication circuits through an outage. Pulling mains power too soon after installation forces the panel to run on a cell that hasn't reached working voltage. Restore mains, allow the full 48-hour conditioning window, and recheck programming before the next test.
