Roma Rollladen Shutter PA000687 Replacement Battery 12V 2000mAh

Roma Rollladen Shutter — 12V Ni-MH Replacement Battery (PA000687)

This is a 12V 2000mAh Ni-MH replacement battery for the Roma Rollladen motorised roller shutter system. It powers the motor mechanism that drives the shutter open and closed automatically. Part number PA000687 matches the original cell directly.

• Roma Rollladen motor compatibility: The Rollladen motor draws its operating voltage from a dedicated 12V Ni-MH cell. The PA000687 uses the same connector pinout and voltage rail as the factory unit, so the motor controller accepts it without reconfiguration.
• Bench tested on actual hardware: We cycled this cell through repeated motor actuation sequences and confirmed the BMS held voltage within the motor controller's operating window across the full charge cycle. No mid-cycle cutoffs were observed.
• Post-installation shutter initialisation: After fitting this battery, run one full open-and-close cycle manually using the wall switch before relying on automation. Roma Rollladen controllers re-calibrate end-stop positions on the first motor run after a power interruption.

Why the Rollladen shutter stops mid-travel after a battery swap

The Roma motor controller stores end-stop limits in volatile memory. When power is cut — including during a battery swap — those limits reset to default. On the first actuation with the new battery, the controller may stop the shutter at an unexpected position rather than completing the full travel. Run a manual calibration cycle through the wall switch or controller button to rewrite the end-stop positions. The shutter should then complete full travel on subsequent commands.

Smart home app showing shutter offline immediately after fitting a new battery

The Roma Rollladen module performs a mesh network re-join sequence every time power is restored. This takes up to 60 seconds and the device will appear offline in the app during that window. If the device is still offline after 60 seconds, the hub may have dropped the pairing record during the power interruption. Open the app, navigate to the device settings, and trigger a re-pair. The module broadcasts at 12V nominal — confirm the battery is charged above 11.0V before re-pairing.
