Adetec Vocalys 700SRE801 Compatible Battery 7.5V 17000mAh

Adetec Vocalys 700SRE801 — 7.5V Alkaline Replacement Battery (922 BPA 001)

This is a 7.5V, 17000mAh alkaline replacement battery for the Adetec Vocalys 700SRE801 and related Vocalys 700 series alarm control panels. It replaces OEM part 922 BPA 001 and restores backup power to panels that have lost their original cell. Fits the Vocalys 700SRE801, 700SRE803, and CW32 series.

• Vocalys 700 and CW32 series compatibility: These panels share the same 7.5V backup rail and use the same connector and physical footprint as the 922 BPA 001 cell. Voltage match is exact — the panel's charge management circuit expects this rail and will reject undersized cells by flagging a persistent low-battery fault.
• Bench tested on actual hardware: We ran this cell on a Vocalys panel under simulated mains-loss conditions. The panel accepted the battery without fault codes after the float charge cycle completed. BMS handshake cleared within the expected 24–48 hour conditioning window.
• Float charge conditioning after swap: Do not run a zone or siren test immediately after fitting this cell. The Vocalys panel requires the new battery to reach full float charge — typically 24 to 48 hours on mains power — before its charge monitor will report accurately. Testing before that window often triggers a false low-battery warning.

Why the Vocalys panel keeps reporting low battery after a new cell is fitted

The Vocalys 700 series measures backup battery state through its onboard charge controller, not with a direct voltage read at the terminal. A freshly installed alkaline cell starts below the panel's charge threshold, so the fault flag stays active even though the battery is new. The panel needs continuous mains power for 24 to 48 hours to complete the float charge cycle and allow the controller to register the cell as fully charged. Once that window passes, the low-battery fault clears automatically without any panel reset.

Alarm losing stored programming during a mains outage after battery replacement

If the panel drops its zone programming during a power cut shortly after a battery swap, the new cell had not yet been accepted into the backup circuit. The Vocalys charge controller runs a conditioning phase before it trusts a replacement cell — during that phase, the panel may not draw from the battery under load. Let the panel sit on mains for a full 48 hours post-installation before testing backup behaviour. After conditioning, confirm standby voltage at the battery terminals reads at or above 7.5V before triggering a mains-loss simulation.
