Jimmy T-DC62 21.6V Cordless Vacuum Replacement Battery 3000mAh

Jimmy PW501 / V7 — 21.6V Li-ion Replacement Battery (T-DC62)

This is a 21.6V, 3000mAh (64.8Wh) Li-ion replacement battery for the Jimmy PW501 and V7 cordless stick vacuums. It matches the OEM part number T-DC62 and connects to the same battery bay and BMS handshake as the factory cell. Use it when the original pack no longer holds a usable charge.

• PW501 and V7 compatibility: Both models run the same 21.6V power rail and use the same T-DC62 connector and BMS communication protocol. The battery pack slots into either unit without modification.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on a PW501 unit. The BMS responded correctly to motor start draw, sustained suction load, and end-of-discharge cutoff — no false trips observed.
• Dock charging on cordless vacuums: Do not leave the PW501 sitting on the dock continuously between uses. Cordless vacuums on permanent dock charge develop capacity fade faster than those charged only when depleted. Charge to full, then remove from the dock.

Suction dropping before the battery indicator reaches low

The PW501 motor draws higher current whenever the filter is partially blocked or the bin is full. That elevated draw causes voltage to sag at the cell level, and the BMS reads it as a near-depleted pack even when capacity remains. The indicator trips early and suction weakens — but the battery is not the cause. Clean the filter and empty the bin first. If suction recovers immediately, the battery is fine.

Motor cuts out mid-clean and restarts after a short pause

This is a BMS overcurrent trip, not a dead battery. Restricted airflow — from a clogged filter, blockage in the hose, or a sealed floor attachment — forces the motor to pull beyond its rated current ceiling. The BMS cuts power to protect the cells, then resets after the pack cools slightly. Clear the restriction, then restart. If the problem disappears, the battery is working exactly as intended. If it persists with a clean filter and clear path, check that the replacement cell voltage reads at least 21.6V fully charged.
