ClareOne Smart Home Panel CLR-C1-BATT Replacement Battery 3.8V 5000mAh

ClareOne CLR-C1-PNL1 Smart Home Panel — 3.8V Li-Polymer Replacement Battery (CLR-C1-BATT)

This 3.8V, 5000mAh lithium-polymer battery replaces the internal backup cell in the ClareOne Smart Home Panel (CLR-C1-PNL1). It keeps the panel running during mains power outages so security monitoring and emergency alerts stay active. Dimensions are 80.60 × 50.00 × 9.00mm — confirm your existing cell matches before ordering.

• CLR-C1-PNL1 fit confirmation: The ClareOne panel uses a single lithium-polymer cell at 3.8V with a dedicated BMS that monitors cell state and signals low-battery warnings to the Clare app. This replacement carries the same OEM part number CLR-C1-BATT and matches the voltage rail the panel's BMS expects.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the ClareOne panel and confirmed the BMS accepted the cell without fault codes, held charge correctly, and triggered the panel's backup mode at the expected low-voltage threshold.
• Post-swap network behaviour: After installing this battery and restoring power, give the panel at least 60 seconds before expecting it to show as online. The ClareOne panel runs a mesh network re-join sequence after any power interruption — cutting that short by checking too early can look like a failed installation when the battery is fine.

Why the ClareOne panel drains this battery faster after a network change

When the panel loses its primary network connection — due to a router change, SSID update, or ISP outage — it increases its polling frequency while trying to reconnect. That elevated polling draws more current from the backup cell than normal standby operation. A battery that looked fine before a network change may now deplete noticeably faster. Restoring a stable network connection returns the panel to its standard low-draw standby mode.

Low battery alert showing immediately after fitting a new cell

If the panel throws a low battery alert within minutes of a new cell being installed, the replacement battery arrived from storage at a voltage below the panel's warning threshold — typically under 3.5V. The BMS reads that as a depleted cell and fires the alert before any charge has occurred. Connect the panel to mains power and allow a full charge cycle to complete. Once the cell climbs above the alert threshold the warning clears automatically.
