About this replacement
Taurus Saugroboter Striker Slim VER. II — 14.4V Ni-MH Replacement Battery (079710000)
This is a 14.4V, 1500mAh Ni-MH battery for the Taurus Saugroboter Striker Slim VER. II robotic vacuum cleaner. It also covers the Striker Slim Ver II and T270 variants sharing the same battery bay and connector. OEM part numbers 079710000 and 086240000 both apply to this cell.
- T270 and Striker Slim VER. II platform: These variants share the same 14.4V rail, physical battery bay, and BMS handshake profile, so one cell covers all three fit models without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Striker Slim platform. The BMS accepted the cell without fault codes and the suction motor reached normal operating draw throughout the test.
- Dock charging habit on robotic vacuums: Do not leave the Striker Slim permanently on its charging dock. Ni-MH cells in continuous trickle charge degrade faster than those charged only when depleted. Charge to full, then remove the unit from the dock until the next cleaning cycle.
Suction dropping before the battery indicator reaches low on the Striker Slim
Ni-MH cells show voltage sag under load before the state-of-charge indicator registers a problem. On a robotic vacuum, a partially blocked filter forces the suction motor to draw above its rated current, accelerating that sag. The battery's BMS then reduces output to protect the cell, and the user sees weaker suction while the indicator still shows charge remaining. Clean or replace the filter first — if suction recovers, the cell is not the cause.
Motor cutting out mid-cycle and then recovering after a pause
This pattern is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked brushroll, clogged filter, or carpet pile jamming the intake — current draw spikes beyond the BMS threshold and the circuit opens. The unit pauses, the BMS resets after the load drops, and the motor restarts. Clear the restriction, then retest. If the cutout continues with an unobstructed intake, measure resting cell voltage — it should sit at or above 14.4V after a full charge.
