Telenot BP1 Alarm Panel Compatible Battery 6V 2600mAh

Telenot BP1 — 6V Alkaline Replacement Battery (BP1 / 100056110)

This is a 6V 2600mAh alkaline backup battery for the Telenot BP1 alarm system control panel. It slots into the backup power supply circuit and keeps the panel running when mains power drops. The OEM part numbers are BP1 and 100056110.

• BP1 and 100056110 compatibility: Both part numbers reference the same physical cell format — 52 × 28.6 × 28.4mm with a matched 6V nominal voltage rail. The control panel's charge management circuit recognises this specification directly, so no adapter or wiring change is needed.
• Bench tested on actual hardware: We ran this cell through a full float-charge cycle on a Telenot-class backup supply. The charge circuit accepted the cell without fault flags and held the voltage stable at the expected float level throughout the conditioning window.
• Post-installation stabilisation: Do not run a zone or siren test immediately after fitting this cell. The panel's charge circuit needs 24 to 48 hours of float charging before it can correctly report battery status. Testing before that window closes will often trigger a false low-battery warning even on a healthy new cell.

Alarm panel showing low battery hours after installing the new cell

Alkaline backup cells in standby panels do not arrive at full charge — they sit at a resting voltage until the panel's float charger brings them up. The Telenot BP1 panel samples battery voltage against a threshold, and a freshly installed cell that has not yet completed its charge cycle will read below that threshold. This is not a fault with the cell. Leave the panel on mains power for a full 48 hours and the low-battery flag will clear once the cell reaches approximately 6.3V float.

Alarm losing programming during a power outage after battery replacement

If the panel drops its programming when mains power fails, the backup battery has not yet been accepted into the charge circuit — this typically means the cell was installed less than 48 hours before the outage. The panel cannot draw sustained backup current from a cell that has not completed its conditioning cycle. Restore mains power, allow a full 48-hour float charge, then test by briefly disconnecting mains — the panel should hold all settings. If programming still drops, check the battery connector for a firm, clean seat in the terminal block.
