Miele Scout RX2 Replacement Battery 14.8V 6700mAh

Miele Scout RX2 / RX3 — 14.8V Li-ion Replacement Battery (10559142)

This is a 14.8V, 6700mAh Li-ion battery for the Miele Scout RX2 and Scout RX3 robotic vacuum cleaners. It slots into the same battery bay as the original and uses the same OEM part reference (10559142 / 11779170). When the original cell degrades, the robot cuts cleaning cycles short or refuses to dock-charge — this replacement restores full operating capacity.

• RX2 and RX3 compatibility: Both models run the same 14.8V four-cell Li-ion architecture and use the same BMS handshake protocol with the charging station. One battery fits both platforms without any modification.
• Bench tested on actual hardware: We cycled this battery through the Scout's charging station and confirmed the BMS communicates correctly — charge acceptance, cell balancing, and protection cutoffs all behaved within spec.
• Dock charging habit on robotic vacuums: Do not leave the Scout sitting on the dock permanently between uses. Robotic vacuums on continuous trickle charge develop capacity fade faster than units charged only when depleted. Charge to full, then remove the robot from the dock if it will sit unused for more than a few days.

Suction dropping before the battery indicator reaches low on the Scout RX2

This happens when the filter is partially blocked and the motor draws more current than its rated load. The BMS sees an overcurrent condition and reduces power to the motor before the battery itself is depleted. The battery indicator still reads mid-range because the cells are fine — the restriction is the problem. Clean or replace the filter, and the full suction level returns at the same charge state.

Scout RX3 not charging after fitting a replacement battery

The Scout's charging station expects a BMS handshake before it begins passing current. If the replacement battery's BMS does not respond correctly, the dock LED may stay amber or show no activity at all. Verify the battery terminals are seated fully — the connector is a friction fit and partial contact breaks the handshake. If the dock still does not begin charging, measure voltage at the battery terminals: a fully discharged cell below 10V may need a brief manual charge cycle to wake the BMS before the dock can take over.
