Silvercrest SSR 3000 A1 Replacement Battery 14.4V 2600mAh

Silvercrest SSR 3000 A1 / SSWR A1 — 14.4V Li-ion Replacement Battery

This is a 14.4V 2600mAh Li-ion battery for the Silvercrest SSR 3000 A1 and SSWR A1 cordless stick vacuums. It slots into the battery bay on both models and restores full motor power when the original cell can no longer hold a charge. Capacity comes from the product data: 2600mAh / 37.44Wh.

• SSR 3000 A1 and SSWR A1 compatibility: Both models run the same 14.4V motor rail and share an identical battery bay geometry and connector pinout. A single cell spec covers both — no adapter or modification needed.
• Bench tested on actual hardware: We cycled this cell through the SSR 3000 A1's BMS under full-load suction draw. The protection circuit held cutoff at the correct low-cell threshold and accepted charge from the OEM dock without handshake errors.
• Dock charging behaviour on cordless vacuums: Do not leave this vacuum sitting on the charging dock continuously. Cordless vacuums left permanently docked develop capacity fade much faster than those charged only when the cell is depleted. Charge to full, then remove from the dock.

Suction dropping before the battery indicator reaches low

This is voltage sag under load, not a failed cell. When the filter is partially blocked, the motor works harder and draws more current than its rated figure. The BMS reads that as a low-voltage event and throttles output before the indicator catches up. Clean or replace the filter first — if suction stabilises, the battery is fine. If sag continues with a clean filter, cell capacity has degraded past the point where it can sustain peak current draw.

Motor cutting out mid-clean and recovering after a few seconds

This is an overcurrent trip from the battery's BMS, not a motor fault. A blockage or restricted airflow forces the motor to spike current above the BMS cutoff threshold — the circuit opens, power drops, and the BMS resets after a few seconds once current falls. Check the filter, brush roll, and hose for any obstruction before assuming the battery is at fault. If cut-outs persist with clear airflow, verify the replacement cell's BMS trip threshold is rated for the SSR 3000 A1's peak draw.
