Cordless vacuum runs for only 1–3 minutes on a full charge, then shuts off

Safety first: Use only Bissell-approved batteries and chargers.

• Fully charge: Charge the battery until the indicator shows full. Leave it on the charger for an additional 30–60 minutes to ensure full top-off.
• Test in low mode: Run the vacuum in standard/low mode and time the runtime. If it is still only a few minutes, the battery capacity is likely degraded.
• Clean contacts: Clean battery and vacuum contacts with isopropyl alcohol to reduce resistance and heat.
• Replace battery: If the vacuum is more than 1–2 years old and runtime is significantly reduced, replace the battery pack with a genuine Bissell replacement.
• Check charger: If a new battery also shows short runtime, test or replace the charger to ensure it is delivering full charge.
