Vacuum runs for only a few minutes on a full charge, no error code shown

Safety: Do not open the battery pack.

• 1. Fully charge: Charge the battery until the charger indicates full. Leave it on the charger for an extra 30 minutes.
• 2. Test runtime: Use the vacuum continuously on low power and time the runtime. Compare with the original specification in the manual.
• 3. Try eco mode: If available, use eco mode to see if runtime improves significantly. Very short runtime in all modes indicates a worn battery.
• 4. Replace battery: If runtime is much lower than specified (e.g., less than 30–40% of original), purchase a compatible SilverCrest replacement battery pack.
