Infinite Prime 7.2V Control Panel Replacement Battery 11AAAH6YMX

Infinite Prime Control Panel — 7.2V Ni-MH Replacement Battery (11AAAH6YMX)

This is a 7.2V, 2000mAh Ni-MH replacement battery for the Infinite Prime Control Panel alarm system. It slots into the panel housing and provides backup power when mains supply is interrupted. Voltage and cell count match the original specification exactly.

• Infinite Prime Control Panel compatibility: The Infinite Prime panel range uses a six-cell Ni-MH pack running at 7.2V nominal. The connector and cell arrangement on this replacement match the factory configuration, covering OEM references 11AAAH6YMX, GP150AAM6YMX, GP220AAM6YMX, INF-BATPNL, and PG800.
• Bench tested on actual hardware: We ran this cell on a representative alarm panel load. The BMS accepted the battery without fault codes, float charge engaged correctly, and the panel transitioned cleanly from mains to battery backup under simulated power loss.
• Post-installation conditioning: Do not run a zone or siren test immediately after fitting this battery. Allow 24–48 hours on float charge first. The panel samples battery voltage during diagnostic routines — an un-conditioned cell will read low and trigger a false low-battery fault even if the battery is healthy.

Alarm panel showing low battery hours after installing new cell

Ni-MH cells ship in a partially discharged state. The Infinite Prime panel monitors terminal voltage and compares it against a threshold — typically around 6.8–7.0V — to decide whether to raise a low-battery fault. A freshly installed cell sitting below that threshold will trigger the fault immediately, even though the battery is not defective. Float charge through the panel's own charging circuit brings the pack to full capacity over 24–48 hours. Once the cell reaches full float voltage, the fault clears on its own without any intervention.

Alarm losing programming during a power outage after battery replacement

If the panel loses its configuration during a mains outage shortly after a battery swap, the replacement cell had not yet been accepted into float charge. The panel requires a minimum charge acceptance period — typically 48 hours on mains — before the backup battery can sustain the memory-hold current through an outage. During that window, a power cut drops panel voltage below the RAM retention threshold and wipes volatile memory. Restore mains power, re-enter panel programming, and allow the full 48-hour conditioning cycle before testing backup operation.
