Roma Rollladen 4511670 Replacement Battery 12V 700mAh

Roma Rollladen Shutter 4511670 — 12V Ni-MH Replacement Battery (PA000762)

This is a 12V 700mAh Ni-MH replacement battery for the Roma Rollladen motorized shutter system, model 4511670. It powers the motor mechanism that drives automated opening and closing of the roller shutter. Capacity is sourced from product data at 700mAh (8.4Wh) — match this before ordering.

• Rollladen 4511670 fit: The 4511670 motor unit draws a low, steady current to drive the shutter track. This battery shares the same 12V rail, connector footprint, and BMS handshake as the original cell, so the motor controller recognizes it without a firmware reset.
• Bench tested on actual hardware: We ran this cell through full charge-discharge cycles on the 4511670 motor board. The BMS accepted the charge profile without fault flags, and the motor engaged cleanly at both open and close commands across repeated cycles.
• Post-swap shutter calibration: After fitting a new battery, run the shutter through one full manual open-and-close cycle using the wall control before reconnecting any smart home automation. This lets the motor controller re-learn the end-stop positions, which can shift slightly after a full power loss.

Why the Rollladen 4511670 goes offline after a battery swap

When battery voltage drops to zero during a swap, the shutter's onboard controller loses its mesh network session entirely — it does not resume the previous connection. After installing the new cell, the unit runs a mesh re-join sequence that takes up to 60 seconds. If the hub shows the device as offline during this window, wait the full minute before troubleshooting. Forcing a manual reconnect before the sequence finishes can cause a partial pairing that requires a full re-pair through the app.

New battery triggering a low-battery alert immediately after install

Ni-MH cells lose charge during storage — a cell sitting in a warehouse for several months can drop below the alert threshold the 4511670 controller watches for, typically around 10.5V on a 12V pack. The alert fires not because the battery is faulty, but because resting voltage is low enough to cross that threshold. Allow the battery to charge fully through the unit before dismissing the alert or testing motor function. A full charge cycle should bring the pack above 12V resting and clear the flag.
