Cordless vacuum shuts off within seconds of starting; battery indicator flashes red

Safety first: Power the unit OFF and remove the battery pack before inspection.

• Fully recharge: Place the Hamilton Beach battery pack on its OEM charger until the charger indicates a full charge (often solid green). Do not interrupt the charge cycle.
• Cool-down period: If the vacuum was used heavily, allow the battery to cool for 30 minutes before recharging. Overheated packs can trigger undervoltage/overcurrent protection.
• Check for loose fit: Ensure the battery pack locks firmly into the vacuum. A loose pack can cause momentary disconnects that trigger E2.
• Test runtime: After a full charge, run the vacuum on low power. If it still shuts off within seconds and the red LED flashes, the pack’s cells or BMS are likely failing.
• Replace battery: Replace with a compatible Hamilton Beach lithium-ion battery pack. Do not attempt to open or repair the battery pack yourself due to fire and shock risk.
