Ursus Trotter Excellenza 2000 Replacement Battery 14.8V 3400mAh

Ursus Trotter Excellenza 2000 — 14.8V Li-ion Replacement Battery

This 14.8V Li-ion battery pack replaces the original cell in the Ursus Trotter Excellenza 2000 cordless vacuum cleaner. Capacity is 3400mAh (50.32Wh), matching the original power spec. It fits the Excellenza 2000 platform and restores cordless operation after the factory cell has degraded through repeated charge cycles.

• Excellenza 2000 fit: The Excellenza 2000 runs a 14.8V four-cell Li-ion pack at a fixed connector and BMS configuration. This replacement matches that voltage rail and physical form factor — 75.50 × 42.50 × 42.00mm — so no adapter or modification is needed.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on the Excellenza 2000 platform. The BMS handled motor-start current draw without tripping and communicated correctly with the vacuum's charge circuit throughout.
• Dock charging habit on the Excellenza 2000: Do not leave the vacuum sitting on the dock continuously between uses. Cordless vacuums kept on permanent dock charge develop capacity fade significantly faster than units charged only when depleted. Charge to full, then remove from the dock.

Suction dropping before the battery indicator shows low

The Excellenza 2000 motor draws more current when airflow is restricted — a partially blocked filter forces the motor to work harder, pulling the pack voltage down faster than the indicator expects. The indicator tracks cell voltage at rest, not under load, so it can still show two bars while suction has already deteriorated noticeably. This is voltage sag under increased draw, not a fault in the battery itself. Clean the filter first; if sag continues with a clean filter, the original cell has likely lost capacity and replacement will restore full suction duration.

Motor cuts out mid-clean then recovers after a short pause

This is a BMS overcurrent trip, not a motor fault. When suction is sustained against a blockage or a heavily loaded carpet, current draw spikes above the BMS threshold and the pack shuts the output. The brief pause resets the BMS and power returns. Check the filter and clear any blockage in the brush head or hose before attributing the cutout to the battery. If the filter is clean and blockages are cleared, check that the pack voltage reads at least 16.4V at full charge — a pack that tops out below that figure has a cell balance issue.
