The vacuum runs for only a few minutes on a full charge and then shuts off.

Safety first: Use only original Sencor batteries and chargers.

• Verify full charge: Charge the vacuum until the indicator shows 100% or all bars lit.
• Test on ECO mode: Run the vacuum on the lowest power setting. If runtime is still very short, the battery is worn.
• Check for overheating: If the battery becomes very hot during short use, cells are likely failing.
• Replace battery: Purchase and install a genuine Sencor replacement battery pack compatible with your model. Dispose of the old battery at an authorized recycling center.
